AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
831 PM PDT FRI MAY 29 2015

.SYNOPSIS...THE HOTTEST WEATHER SO FAR THIS YEAR IS EXPECTED OVER
THE WEEKEND WITH HIGHS APPROACHING RECORD LEVELS IN SOME AREAS.
TEMPERATURES WILL SLOWLY RETURN TO NEAR NORMAL BY THE MIDDLE OF NEXT
WEEK WITH INCREASING AFTERNOON BREEZES AS A WEAK TROUGH OF LOW
PRESSURE MOVES OVER THE WESTERN STATES.
&&

.UPDATE...MADE A FEW TWEAKS TO THE SKY GRIDS TO ACCOUNT FOR SOME
HIGH CLOUDS DRIFTING OVER THE REGION THIS EVENING. ALSO REDUCED POPS
NOW THAT SHOWER ACTIVITY WAS ALL BUT OVER. THERE COULD STILL BE A
FEW DROPS FALLING IN FAR EASTERN LINCOLN COUNTY. OTHERWISE THE
FORECAST IS IN GOOD SHAPE AND NO OTHER UPDATES ARE NEEDED AT THIS
TIME.
&&

.PREV DISCUSSION...
243 PM PDT FRI MAY 29 2015

.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT.

LINGERING MOISTURE AND INSTABILITY OVER EAST CENTRAL NEVADA AND
NORTHWEST ARIZONA WILL PRODUCE A FEW SHOWERS AND THUNDERSTORMS
THROUGH EARLY THIS EVENING BEFORE IT IS PUSHED TO THE NORTHEAST BY A
STRONG RIDGE MIGRATING INLAND FROM THE WEST COAST. THIS WILL BRING A
TASTE OF SUMMERLIKE TEMPERATURES WITH HIGH TEMPS APPROACHING RECORD
LEVELS FOR SOME AREAS SATURDAY AND ESPECIALLY SUNDAY. THE RIDGE AXIS
IS FORECAST TO MOVE OVERHEAD SATURDAY THEN CONTINUE MIGRATING EAST
OVER UTAH AND THE INTERMOUNTAIN REGION BY SUNDAY AHEAD OF A LOW
PRESSURE SYSTEM APPROACHING NORTHERN CALIFORNIA. SOME THIN CIRRUS
WILL MOVE OVER THE REGION TONIGHT AND SATURDAY WITH THE RIDGE BUT
SHOULD NOT BE DENSE ENOUGH TO LIMIT SUNSHINE. INCREASING SOUTH-
SOUTHWEST BREEZES SUNDAY AFTERNOON AHEAD OF THE PACIFIC NORTHWEST
TROUGH WILL AID BOUNDARY LAYER MIXING AND PRODUCE THE HOTTEST DAY OF
THE FORECAST PERIOD. WITH HIGHS OF 104-110 ACROSS MUCH OF THE MOJAVE
DESERT REGION. SOME TWEAKS WERE MADE TO MINIMUM TEMPERATURE GRIDS
BASED ON OBSERVED TRENDS...OTHERWISE LITTLE CHANGE WAS NEEDED TO THE
PREVIOUS FORECAST.

.LONG TERM...MONDAY THOUGH FRIDAY.

AFTER A SCORCHING WEEKEND GENERAL WEAK TROUGHING WILL TAKE OVER THE
WESTERN US...LEADING TO SOME SLIGHT COOLING WITH TEMPERATURES
RETURNING CLOSER TO NORMAL. LIFT AND MOISTURE ASSOCIATED WITH ANY
SHORTWAVE ACTIVITY MOVING THROUGH FLOW SHOULD REMAIN WELL NORTH OF
THE AREA...WITH ANY IMPACTS AROUND THE AREA LIMITED TO WIND AND HIGH
CLOUDS...ESPECIALLY ON MONDAY. BOTH THE GFS AND EURO HINT AT MORE
ENERGY COMING SOUTHWARD TOWARDS THE END OF NEXT WEEK.
&&

.AVIATION...FOR MCCARRAN...WINDS WILL FAVOR TYPICAL DIURNAL TRENDS
WITH SPEEDS GENERALLY LESS THAN 9 KNOTS THROUGH SATURDAY. TEMPS WILL
REACH OR EXCEED 100F BOTH SATURDAY AND SUNDAY FOR A FEW HOURS DURING
THE AFTERNOON AND EARLY EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED SHOWERS AND THUNDERSTORMS OVER EAST CENTRAL
NEVADA AND NORTHWEST ARIZONA WILL DISSIPATE BY EARLY THIS EVENING.
DRY CONDITIONS WITH WINDS FAVORING TYPICAL DIURNAL DIRECTIONAL
TRENDS AT 10 KTS OR LESS CAN BE EXPECTED THROUGH SATURDAY UNDER
CIRRUS CLOUDS. SLIGHTLY HIGHER SPEEDS ARE EXPECTED SUNDAY AFTERNOON
AND EVENING WITH GUSTS OF 15-25 KTS POSSIBLE ESPECIALLY IN AND
AROUND KDAG.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
247 PM PDT FRI MAY 29 2015

.SYNOPSIS...

HIGH PRESSURE WILL BRING VERY WARM TEMPERATURES THROUGH THIS
WEEKEND. A COLD FRONT WILL BRING GUSTY WINDS SUNDAY AND MONDAY,
WITH TEMPERATURES DROPPING TO NEAR NORMAL FROM MONDAY THROUGH MUCH
OF NEXT WEEK. LOW PRESSURE SETTING UP IN THE PACIFIC NORTHWEST WILL
BRING POSSIBLE SHOWERS AND THUNDERSTORMS MONDAY THROUGH THURSDAY,
MAINLY NORTH OF INTERSTATE 80.


&&

.SHORT TERM...

THE RIDGE OF HIGH PRESSURE CONTINUES TO STRENGTHEN OVER THE WEST
COAST AS WE GO INTO THE WEEKEND. THERE REMAINS A VERY SLIGHT CHANCE
OF A STORM NEAR THE MONO-MINERAL COUNTY CONVERGENCE ZONE LATE TODAY,
BUT IT LOOKS AS THOUGH IT WILL BE MOSTLY TOWERING CUMULUS. WARMING
TEMPERATURES ALOFT TOMORROW WILL KEEP CONVECTION CAPPED WITH GOOD
MIXING. TEMPERATURES ACROSS THE LOWER VALLEYS WILL REACH TO LOW 90S
SATURDAY WITH LOW 80S IN THE SIERRA.

A FAST MOVING AREA OF LOW PRESSURE APPROACHES NORTHERN CA/NV ON
SUNDAY INCREASING WINDS ACROSS THE REGION. LATE IN THE DAY ON
SUNDAY, 700MB WINDS INCREASE TO AROUND 40KT, AS THE JET MOVES IN.
MODELS HAVE BEEN TRENDING SLOWER WITH THE JET CORE AND STRONGEST
WINDS ALOFT, BRINGING THEM IN AFTER MIDNIGHT SUNDAY NIGHT. DURING
THE DAY ON SUNDAY, WIND GUSTS 30 TO 35 MPH ARE LIKELY, ESPECIALLY
ALONG THE SIERRA FRONT FROM MINDEN NORTH TO SUSANVILLE, THEN PICKING
UP LATE IN THE DAY BEFORE THE SUN GOES DOWN. LAKE WIND ADVISORIES
WILL BE POSSIBLE, DUE TO GUSTY WINDS AND CHOPPY LAKE CONDITIONS ON
TAHOE AND PYRAMID (LATE IN THE DAY). ANYONE PLANNING BOATING OR
KAYAKING ON TAHOE OR PYRAMID ON SUNDAY SHOULD BE AWARE OF POTENTIAL
CHOPPY CONDITIONS.

THE TROUGH AXIS SWINGS THROUGH NORTHERN CA/NV ON SUNDAY NIGHT,
BECOMING NEGATIVELY TILTED. THERE IS A SLIGHT CHANCE OF NOCTURNAL
SHOWERS SUNDAY NIGHT INTO MONDAY MORNING, DUE TO THE STRONG FORCING
ALTHOUGH MOISTURE IS LACKING. POST-FRONTAL GRADIENT WILL REMAIN
TIGHT ON MONDAY WITH BREEZY WEST WINDS. HOON

.LONG TERM...TUESDAY THROUGH FRIDAY...

VERY FEW CHANGES TO THE LONG TERM CONCERNING FORECASTED WEATHER
ELEMENTS. MODELS REMAIN IN FAIRLY GOOD AGREEMENT THROUGH EARLY
WEDNESDAY BEFORE SIGNIFICANT DIVERGING OCCURS. RIDGING BEGINS TO
SHIFT EASTWARD TUESDAY ALLOWING FOR COOLER TEMPERATURES THAN THIS
WEEKEND WITH HIGHS BECOMING MUCH MORE SEASONABLE IN THE UPPER 70S BY
MID WEEK. DID LOWER TEMPERATURES A SMALL BIT AS A NOD TO THE ECMWF
WHICH DIGS AN UPPER LOW WEDNESDAY THROUGH FRIDAY WHILE GFS MAINTAINS
A TROUGH SKIRTING THE OREGON BORDER. AS SUCH, FORECASTER CONFIDENCE
IS LOW FOR PRECIPITATION CHANCES UNTIL MODELS COME TO MORE OF A
CONSENSUS. THE ONLY OTHER TING TO NOTE WILL BE THE POSSIBILITY OF
SOME BREEZY CONDITIONS, ESPECIALLY NORTH OF HIGHWAY 50 AS THE
APPROACHING TROUGH TIGHTENS THE PRESSURE GRADIENT WEDNESDAY
AFTERNOON. BOYD

&&

.AVIATION...

VFR CONDITIONS ARE EXPECTED THROUGH THE WEEKEND WITH FAIRLY LIGHT
WINDS THROUGH SATURDAY. EACH DAY COULD SEE GUSTIER LATE AFTERNOON
WINDS EAST OF THE SIERRA...TYPICAL FOR THE WARMER MONTHS. CONVECTION
IS ALSO A POSSIBILITY EACH DAY...MAINLY OVER THE FAR SOUTHERN AREAS
SOUTH OF A LINE FROM BRIDGEPORT TO YERINGTON TO AUSTIN. ANY
CONVECTION SATURDAY SHOULD BE ISOLATED ENOUGH THAT EVEN IF THUNDER
DOES DEVELOP STORMS COULD BE NAVIGATED AROUND.

BY SUNDAY AFTERNOON SURFACE WINDS WILL BE STRONGER WITH GUSTS TO
NEAR 30 KTS AND RIDGE GUSTS APPROACHING 50 KTS OR MORE. CLOUDS ALSO
INCREASE LATE SUNDAY BUT CIGS SHOULD REMAIN VFR. 20/BOYD

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
244 PM PDT FRI MAY 29 2015

.SYNOPSIS...HIGH PRESSURE REMAINS OVER THE AREA THROUGH THE
WEEKEND ALLOWING TEMPERATURES TO CLIMB INTO THE MID 80S TO LOW
90S. A THUNDERSTORM OR TWO MAY DEVELOP EACH DAY THROUGH NEXT
WEEK. AN UPPER LOW WILL BRING COOLER TEMPERATURES AFTER MONDAY.

&&

.SHORT TERM...TONIGHT THROUGH SUNDAY. THE FORECAST MODELS ARE IN
FAIRLY GOOD AGREEMENT WITH BUILDING HIGH PRESSURE OVER THE CWA.
THIS WILL DRY OUT THE LOWER LEVELS ALLOWING TEMPERATURES TO CLIMB
INTO THE MID 80S TO LOWER 90S OVER THE WEEKEND. SHOULD BE ENOUGH
INSTABILITY TO TRIGGER AN AFTERNOON THUNDERSTORM OR TWO OVER
EASTERN AND EAST CENTRAL NV...BUT POPS ARE EXPECTED TO LOW WITH
THE LIMITED LOW LEVEL MOISTURE AVAILABLE.

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY. A COUPLE OF LOW PRESSURE
SYSTEMS WILL AFFECT THE FORECAST AREA DURING THIS PERIOD. THE FIRST
SHORT WAVE WILL BE MOVING ONTO THE PACIFIC NORTHWEST COAST SUNDAY
NIGHT AND MONDAY WITH ENOUGH MOISTURE AND LIFT TO DEVELOP SOME
SHOWERS AND THUNDERSTORMS ACROSS NORTHERN NV, WITH POPS IN THE 15-30
PCT RANGE. AS THIS SHORT WAVE MOVES ACROSS THE PACIFIC NORTHWEST ON
TUESDAY MOISTURE WILL BE CONFINED TO THE FAR NORTH, OVER NORTHERN
HUMBOLDT AND NORTHERN ELKO COUNTIES FOR A FEW SHOWERS AND
THUNDERSTORMS IN THOSE AREAS. MODEL DIFFERENCES CROP UP WITH REGARDS
TO THE SECOND SHORT WAVE THU/FRI WITH THE GFS/CANADIAN MODELS MOVING
THE CENTER OF THIS FEATURE ACROSS THE PACIFIC NORTHWEST WITH THE
SOUTHERN PORTION MOVING ACROSS NORTHERN NV FOR SOME SHOWERS AND
THUNDERSTORMS, MAINLY NORTH. THE ECMWF MODEL HOWEVER DROPS THIS
FEATURE SOUTHWARD INTO CA AS A CLOSED LOW THU/FRI KEEPING MOISTURE
MAINLY CONFINED TO WESTERN NV. INHERITED FORECAST WAS IN LINE WITH
THE GFS/CANADIAN SOLUTION AND DID NOT DEVIATE MUCH FROM THAT AS
ECMWF CONTINUES TO BE THE OUTLIER.

&&

.AVIATION...SOME INSTABILITY AND MOISTURE FOR ISOLATED THUNDERSTORMS
ACROSS CENTRAL NV TIL 03Z, WITH A 10-15 PCT CHANCE OF A THUNDERSTORM
AFFECTING THE KELY TERMINAL. NO THUNDERSTORMS EXPECTED AT KTPH AS
MOISTURE AND INSTABILITY WILL REMAIN TO THE NORTH AND EAST OF THIS
TERMINAL. NO THUNDERSTORMS EXPECTED TO AFFECT ANY TAF TERMINALS ON
SATURDAY.

&&

.LKN WATCHES/WARNINGS/ADVISORIES...NONE.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
243 PM PDT FRI MAY 29 2015

.SYNOPSIS...THE HOTTEST WEATHER SO FAR THIS YEAR IS EXPECTED OVER
THE WEEKEND WITH HIGHS APPROACHING RECORD LEVELS IN SOME AREAS.
TEMPERATURES WILL SLOWLY RETURN TO NEAR NORMAL BY THE MIDDLE OF NEXT
WEEK WITH INCREASING AFTERNOON BREEZES AS A WEAK TROUGH OF LOW
PRESSURE MOVES OVER THE WESTERN STATES.
&&

.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT.

LINGERING MOISTURE AND INSTABILITY OVER EAST CENTRAL NEVADA AND
NORTHWEST ARIZONA WILL PRODUCE A FEW SHOWERS AND THUNDERSTORMS
THROUGH EARLY THIS EVENING BEFORE IT IS PUSHED TO THE NORTHEAST BY A
STRONG RIDGE MIGRATING INLAND FROM THE WEST COAST. THIS WILL BRING A
TASTE OF SUMMERLIKE TEMPERATURES WITH HIGH TEMPS APPROACHING RECORD
LEVELS FOR SOME AREAS SATURDAY AND ESPECIALLY SUNDAY. THE RIDGE AXIS
IS FORECAST TO MOVE OVERHEAD SATURDAY THEN CONTINUE MIGRATING EAST
OVER UTAH AND THE INTERMOUNTAIN REGION BY SUNDAY AHEAD OF A LOW
PRESSURE SYSTEM APPROACHING NORTHERN CALIFORNIA. SOME THIN CIRRUS
WILL MOVE OVER THE REGION TONIGHT AND SATURDAY WITH THE RIDGE BUT
SHOULD NOT BE DENSE ENOUGH TO LIMIT SUNSHINE. INCREASING SOUTH-
SOUTHWEST BREEZES SUNDAY AFTERNOON AHEAD OF THE PACIFIC NORTHWEST
TROUGH WILL AID BOUNDARY LAYER MIXING AND PRODUCE THE HOTTEST DAY OF
THE FORECAST PERIOD. WITH HIGHS OF 104-110 ACROSS MUCH OF THE MOJAVE
DESERT REGION. SOME TWEAKS WERE MADE TO MINIMUM TEMPERATURE GRIDS
BASED ON OBSERVED TRENDS...OTHERWISE LITTLE CHANGE WAS NEEDED TO THE
PREVIOUS FORECAST.

.LONG TERM...MONDAY THOUGH FRIDAY.

AFTER A SCORCHING WEEKEND GENERAL WEAK TROUGHING WILL TAKE OVER THE
WESTERN US...LEADING TO SOME SLIGHT COOLING WITH TEMPERATURES
RETURNING CLOSER TO NORMAL. LIFT AND MOISTURE ASSOCIATED WITH ANY
SHORTWAVE ACTIVITY MOVING THROUGH FLOW SHOULD REMAIN WELL NORTH OF
THE AREA...WITH ANY IMPACTS AROUND THE AREA LIMITED TO WIND AND HIGH
CLOUDS...ESPECIALLY ON MONDAY. BOTH THE GFS AND EURO HINT AT MORE
ENERGY COMING SOUTHWARD TOWARDS THE END OF NEXT WEEK.
&&

.AVIATION...FOR MCCARRAN...WINDS WILL FAVOR TYPICAL DIURNAL TRENDS
WITH SPEEDS GENERALLY LESS THAN 9 KNOTS THROUGH SATURDAY. TEMPS WILL
REACH OR EXCEED 100F BOTH SATURDAY AND SUNDAY FOR A FEW HOURS DURING
THE AFTERNOON AND EARLY EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED SHOWERS AND THUNDERSTORMS OVER EAST CENTRAL
NEVADA AND NORTHWEST ARIZONA WILL DISSIPATE BY EARLY THIS EVENING.
DRY CONDITIONS WITH WINDS FAVORING TYPICAL DIURNAL DIRECTIONAL
TRENDS AT 10 KTS OR LESS CAN BE EXPECTED THROUGH SATURDAY UNDER
CIRRUS CLOUDS. SLIGHTLY HIGHER SPEEDS ARE EXPECTED SUNDAY AFTERNOON
AND EVENING WITH GUSTS OF 15-25 KTS POSSIBLE ESPECIALLY IN AND
AROUND KDAG.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTERS ARE ENCOURAGED TO REPORT
ANY SIGNIFICANT WEATHER CONDITIONS ACCORDING TO STANDARD OPERATING
PROCEDURES.

950 AM PDT FRI MAY 29 2015

.SYNOPSIS...OUTSIDE OF A STRAY SHOWER OR THUNDERSTORM ACROSS THE
HIGHER ELEVATIONS OF THE SOUTHERN GREAT BASIN THIS AFTERNOON AND
EVENING DRY CONDITIONS ARE EXPECTED ACROSS THE AREA TODAY. THE
HOTTEST WEATHER OF THE YEAR SO FAR IS EXPECTED THIS WEEKEND.
TEMPERATURES WILL SLOWLY RETURN TO NEAR NORMAL BY THE MIDDLE OF NEXT
WEEK.
&&

.UPDATE...VISIBLE SATELLITE LOOPS SHOWED SOME CUMULUS BEGINNING TO
DEVELOP OVER EAST CENTRAL NEVADA THIS MORNING WHICH MAY LEAD TO A
FEW SHOWERS OR THUNDERSTORMS OVER NORTHERN LINCOLN COUNTY THIS
AFTERNOON. THE REST OF THE FORECAST AREA WILL BE VERY WARM AND DRY
AS INDICATED IN THE INHERITED GRIDS AND AS DETAILED IN THE PREVIOUS
DISCUSSION. NO IMMEDIATE CHANGES NEEDED.
&&

.PREV DISCUSSION...
240 AM PDT FRI MAY 29 2015

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT.

CIRRUS WAS EXITING THE EASTERN PARTS OF THE AREA EARLY THIS MORNING
AS A JET STREAK PULLS ON EAST. ALTHOUGH RIDGING ALOFT WILL BUILD
INTO CALIFORNIA TODAY, MORE CIRRUS WILL SPILL IN OVER THE TOP OF THE
RIDGE INTO OUR AREA THIS AFTERNOON INTO TONIGHT. HOWEVER, IT SHOULD
NOT BE TOO EXTENSIVE.

WITH THE RIDGE BUILDING IN TODAY HIGH TEMPS WILL RISE A COUPLE OF
DEGREES FROM THURSDAY. WE ONCE AGAIN WENT WITH THE WARMER END OF
GUIDANCE WHICH WAS THE MAV (GFS). AT MCCARRAN AIRPORT TODAY WE ARE
FORECASTING A HIGH OF 99 BUT MANY SPOTS ON THE EAST SIDE OF THE LAS
VEGAS VALLEY WILL SEE TRIPLE DIGITS TODAY.

THERE IS STILL JUST ENOUGH MID-LEVEL MOISTURE IN PLACE AND A WEAK
RIPPLE NOTED IN THE 500 MB HEIGHTS PROGGED FOR THIS AFTERNOON OVER
THE SOUTHERN GREAT BASIN THAT AN ISOLATED SHOWER OR THUNDERSTORM MAY
POP WITH THE HEATING OF THE DAY MAINLY ACROSS NORTHERN LINCOLN AND
NORTHERN INYO COUNTIES. THIS ACTIVITY SHOULD END BY THIS EVENING AND
THE LATEST HRRR MODEL SUPPORTED THE CURRENT POPS.

EVEN WARMER (MAYBE HOTTER DEPENDING ON YOUR TAKE) IS EXPECTED THIS
WEEKEND ACROSS THE AREA AS THE RIDGE ALOFT BUILDS OVERHEAD ON
SATURDAY THEN GETS PUSHED EAST ON SUNDAY BY AN APPROACHING LONGWAVE
MID/UPPER LEVEL TROUGH. THIS WILL PUSH TEMPS UP A FEW DEGREES EACH
DAY WITH SUNDAY BEING THE WARMEST DAY AS WE GET ON THE BACK SIDE OF
THE RIDGE AND LOW-LEVEL MIXING INCREASES. WE CONTINUED TO SIDE WITH
THE WARMER MAV FOR HIGH TEMPS WHICH PUTS LAS VEGAS AT THE FIRST
TRIPLE DIGITS OF THE YEAR AT MCCARRAN ON SATURDAY. THIS WILL PUT
HIGH TEMPS NEAR RECORD LEVELS ON SUNDAY IN LAS VEGAS (RECORD IS 104
SET IN 2002). OTHERWISE DRY CONDITIONS ARE EXPECTED AREA-WIDE THIS
WEEKEND WITH SLIGHTLY GUSTIER WINDS SUNDAY AFTERNOON AND EVENING
FROM THE SOUTH TO SOUTHWEST ESPECIALLY AROUND BARSTOW.

REMEMBER TO STAY HYDRATED THIS WEEKEND AND IF IN THE HIGHER
MOUNTAINS BE CAREFUL FOR THE IMPACTS OF SNOW MELT INCLUDING COLD AND
RAPID FLOWS IN STREAMS AND CREEKS AND MELTED SNOW REFREEZING AND
FORMING ICE ON TRAILS.

.LONG TERM...MONDAY THOUGH FRIDAY MORNING.

AFTER A SCORCHING WEEKEND GENERAL WEAK TROUGHING WILL TAKE OVER THE
WESTERN US...LEADING TO SOME SLIGHT COOLING WITH TEMPERATURES
RETURNING CLOSER TO NORMAL. LIFT AND MOISTURE ASSOCIATED WITH ANY
SHORTWAVE ACTIVITY MOVING THROUGH FLOW SHOULD REMAIN WELL NORTH OF
THE AREA...WITH ANY IMPACTS AROUND THE AREA LIMITED TO WIND AND HIGH
CLOUDS...ESPECIALLY ON MONDAY. BOTH THE GFS AND EURO HINT AT MORE
ENERGY COMING SOUTHWARD TOWARDS THE END OF NEXT WEEK.
&&

.AVIATION...FOR MCCARRAN...EXPECT WINDS TO FAVOR TYPICAL DIURNAL
DIRECTIONS THROUGH THIS EVENING. SPEEDS OF 8-12 KTS WITH GUSTS TO 14-
18 KTS ARE EXPECTED IN THE LATE AFTERNOON AND EARLY EVENING
OTHERWISE WINDS SHOULD MAINLY BE 8 KTS OR LESS. FEW-SCT CLOUDS AT
TIMES AOA 25K FEET. TEMPS WILL REACH OR EXCEED 100F BOTH SATURDAY
AND SUNDAY FOR A FEW HOURS DURING THE AFTERNOON AND EARLY EVENING.
OTHERWISE WINDS WILL FAVOR TYPICAL DIURNAL DIRECTIONAL TRENDS
THROUGH THE WEEKEND WITH SLIGHTLY HIGHER SPEEDS ON SUNDAY EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED SHRA/TSRA ARE EXPECTED AFTER 20Z TODAY THROUGH
AROUND 05Z SATURDAY ALONG AND NORTH OF KBIH-KBJN-KCDC LINE.
OTHERWISE EXPECT DRY CONDITIONS WITH WINDS FAVORING TYPICAL DIURNAL
DIRECTIONAL TRENDS AT 10 KTS OR LESS. DRY CONDITIONS ARE EXPECTED
AREA-WIDE THIS WEEKEND WITH WINDS AGAIN FAVORING TYPICAL DIURNAL

MID/UPPER LEVEL TROUGH. THIS WILL PUSH TEMPS UP A FEW DEGREES EACH
DAY WITH SUNDAY BEING THE WARMEST DAY AS WE GET ON THE BACK SIDE OF
THE RIDGE AND LOW-LEVEL MIXING INCREASES. WE CONTINUED TO SIDE WITH
THE WARMER MAV FOR HIGH TEMPS WHICH PUTS LAS VEGAS AT THE FIRST
TRIPLE DIGITS OF THE YEAR AT MCCARRAN ON SATURDAY. THIS WILL PUT
HIGH TEMPS NEAR RECORD LEVELS ON SUNDAY IN LAS VEGAS (RECORD IS 104
SET IN 2002). OTHERWISE DRY CONDITIONS ARE EXPECTED AREA-WIDE THIS
WEEKEND WITH SLIGHTLY GUSTIER WINDS SUNDAY AFTERNOON AND EVENING
FROM THE SOUTH TO SOUTHWEST ESPECIALLY AROUND BARSTOW.

REMEMBER TO STAY HYDRATED THIS WEEKEND AND IF IN THE HIGHER
MOUNTAINS BE CAREFUL FOR THE IMPACTS OF SNOW MELT INCLUDING COLD AND
RAPID FLOWS IN STREAMS AND CREEKS AND MELTED SNOW REFREEZING AND
FORMING ICE ON TRAILS.

.LONG TERM...MONDAY THOUGH FRIDAY MORNING.

AFTER A SCORCHING WEEKEND GENERAL WEAK TROUGHING WILL TAKE OVER THE
WESTERN US...LEADING TO SOME SLIGHT COOLING WITH TEMPERATURES
RETURNING CLOSER TO NORMAL. LIFT AND MOISTURE ASSOCIATED WITH ANY
SHORTWAVE ACTIVITY MOVING THROUGH FLOW SHOULD REMAIN WELL NORTH OF
THE AREA...WITH ANY IMPACTS AROUND THE AREA LIMITED TO WIND AND HIGH
CLOUDS...ESPECIALLY ON MONDAY. BOTH THE GFS AND EURO HINT AT MORE
ENERGY COMING SOUTHWARD TOWARDS THE END OF NEXT WEEK.

.AVIATION...FOR MCCARRAN...EXPECT WINDS TO FAVOR TYPICAL DIURNAL
DIRECTIONS THROUGH THIS EVENING. SPEEDS OF 8-12 KTS WITH GUSTS TO 14-
18 KTS ARE EXPECTED IN THE LATE AFTERNOON AND EARLY EVENING
OTHERWISE WINDS SHOULD MAINLY BE 8 KTS OR LESS. FEW-SCT CLOUDS AT
TIMES AOA 25K FEET. TEMPS WILL REACH OR EXCEED 100F BOTH SATURDAY
AND SUNDAY FOR A FEW HOURS DURING THE AFTERNOON AND EARLY EVENING.
OTHERWISE WINDS WILL FAVOR TYPICAL DIURNAL DIRECTIONAL TRENDS
THROUGH THE WEEKEND WITH SLIGHTLY HIGHER SPEEDS ON SUNDAY EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED SHRA/TSRA ARE EXPECTED AFTER 20Z TODAY THROUGH
AROUND 05Z SATURDAY ALONG AND NORTH OF KBIH-KBJN-KCDC LINE.
OTHERWISE EXPECT DRY CONDITIONS WITH WINDS FAVORING TYPICAL DIURNAL
DIRECTIONAL TRENDS AT 10 KTS OR LESS. DRY CONDITIONS ARE EXPECTED

950 AM PDT FRI MAY 29 2015

.SYNOPSIS...OUTSIDE OF A STRAY SHOWER OR THUNDERSTORM ACROSS THE
HIGHER ELEVATIONS OF THE SOUTHERN GREAT BASIN THIS AFTERNOON AND
EVENING DRY CONDITIONS ARE EXPECTED ACROSS THE AREA TODAY. THE
HOTTEST WEATHER OF THE YEAR SO FAR IS EXPECTED THIS WEEKEND.
TEMPERATURES WILL SLOWLY RETURN TO NEAR NORMAL BY THE MIDDLE OF NEXT
WEEK.
&&

.UPDATE...VISIBLE SATELLITE LOOPS SHOWED SOME CUMULUS BEGINNING TO
DEVELOP OVER EAST CENTRAL NEVADA THIS MORNING WHICH MAY LEAD TO A
FEW SHOWERS OR THUNDERSTORMS OVER NORTHERN LINCOLN COUNTY THIS
AFTERNOON. THE REST OF THE FORECAST AREA WILL BE VERY WARM AND DRY
AS INDICATED IN THE INHERITED GRIDS AND AS DETAILED IN THE PREVIOUS
DISCUSSION. NO IMMEDIATE CHANGES NEEDED.
&&

.PREV DISCUSSION...
240 AM PDT FRI MAY 29 2015

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT.

CIRRUS WAS EXITING THE EASTERN PARTS OF THE AREA EARLY THIS MORNING
AS A JET STREAK PULLS ON EAST. ALTHOUGH RIDGING ALOFT WILL BUILD
INTO CALIFORNIA TODAY, MORE CIRRUS WILL SPILL IN OVER THE TOP OF THE
RIDGE INTO OUR AREA THIS AFTERNOON INTO TONIGHT. HOWEVER, IT SHOULD
NOT BE TOO EXTENSIVE.

WITH THE RIDGE BUILDING IN TODAY HIGH TEMPS WILL RISE A COUPLE OF
DEGREES FROM THURSDAY. WE ONCE AGAIN WENT WITH THE WARMER END OF
GUIDANCE WHICH WAS THE MAV (GFS). AT MCCARRAN AIRPORT TODAY WE ARE
FORECASTING A HIGH OF 99 BUT MANY SPOTS ON THE EAST SIDE OF THE LAS
VEGAS VALLEY WILL SEE TRIPLE DIGITS TODAY.

THERE IS STILL JUST ENOUGH MID-LEVEL MOISTURE IN PLACE AND A WEAK
RIPPLE NOTED IN THE 500 MB HEIGHTS PROGGED FOR THIS AFTERNOON OVER
THE SOUTHERN GREAT BASIN THAT AN ISOLATED SHOWER OR THUNDERSTORM MAY
POP WITH THE HEATING OF THE DAY MAINLY ACROSS NORTHERN LINCOLN AND
NORTHERN INYO COUNTIES. THIS ACTIVITY SHOULD END BY THIS EVENING AND
THE LATEST HRRR MODEL SUPPORTED THE CURRENT POPS.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
322 AM PDT FRI MAY 29 2015

.SYNOPSIS...

HIGH PRESSURE WILL BRING VERY WARM TEMPERATURES THROUGH THIS
WEEKEND. A COLD FRONT WILL BRING GUSTY WINDS SUNDAY AND MONDAY,
WITH TEMPERATURES DROPPING TO NEAR NORMAL FROM MONDAY THROUGH MUCH
OF NEXT WEEK. LOW PRESSURE SETTING UP IN THE PACIFIC NORTHWEST
WILL BRING POSSIBLE SHOWERS AND THUNDERSTORMS MONDAY THROUGH
THURSDAY, MAINLY NORTH OF INTERSTATE 80.

&&

.SHORT TERM...

THE WARMING TREND WILL CONTINUE FOR THE NEXT COUPLE OF DAYS AS
UPPER LEVEL RIDGE AXIS MOVES ACROSS CALIFORNIA TODAY AND INTO THE
GREAT BASIN ON SATURDAY. FOR TODAY, WEAK FLOW IN THE MINERAL-MONO
COUNTY CONVERGENCE ZONE ALONG WITH SOME INCREASE IN INSTABILITY
MAY TRIGGER ISOLATED LATE DAY CONVECTION. MODEL SOUNDINGS ALSO SHOW
A WEAKER CAP IN THIS AREA COMPARED TO YESTERDAY, SO WE ADDED A
SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS FOR PARTS OF MONO AND
MINERAL COUNTIES. ANY CELLS THAT DEVELOP ARE LIKELY TO BE SLOW
MOVING BUT ALSO SHORT LIVED DUE TO LIMITED FORCING, WITH ACTIVITY
WINDING DOWN AFTER SUNSET.

FOR THIS WEEKEND, AIR MASS BECOMES MORE STABLE WITH THUNDERSTORMS
UNLIKELY TO DEVELOP, AS RIDGE AXIS MOVING EAST ACROSS THE GREAT
BASIN BRINGS DRIER SOUTHWEST FLOW ALOFT. IMPROVED MIXING EACH DAY
WILL LEAD TO MANY LOWER ELEVATION SITES REACHING OR EXCEEDING 90
DEGREES.

WINDS WILL INCREASE SUNDAY AFTERNOON AND EVENING AS LOW PRESSURE
APPROACHES THE NORTHERN CALIFORNIA COAST. LATEST GUIDANCE IS A
LITTLE SLOWER AND FARTHER WEST WITH THE TRACK OF THIS LOW COMPARED
TO PREVIOUS RUNS, SO WE BACKED OFF A BIT ON WIND SPEEDS DURING THE
AFTERNOON, BUT KEPT PEAK GUSTS OF 30-35 MPH IN PLACE FOR SUNDAY
EVENING. IN ADDITION, WE ONLY DROPPED MAX TEMPS A FEW DEGREES
FROM SATURDAY, WITH LITTLE CHANGE NEAR AND EAST OF THE HIGHWAY 95
CORRIDOR.

AS THE TROUGH AND COLD FRONT MOVES ACROSS NORTHERN NV SUNDAY NIGHT,
COOLER CONDITIONS WILL BEGIN TO SPREAD OVER THE REGION. THE
POTENTIAL FOR PRECIP IS LOW, EXCEPT FOR POSSIBLE EARLY MORNING
SHOWERS IN AREAS NORTH OF FALLON-PYRAMID LAKE WHERE INCREASED
FORCING ALOFT COMBINES WITH AN AREA OF MID LEVEL MOISTURE. MJD

.LONG TERM...MONDAY THROUGH THURSDAY...

THERE IS REALLY NO SIGNIFICANT CHANGE TO FORECAST REASONING THIS
CYCLE AS OPPOSED TO THE PREVIOUS. THE DETERMINISTIC MODELS ARE IN
DECENT AGREEMENT THAT A BROAD TROUGH OF LOW PRESSURE WILL DEVELOP
THROUGH THE EARLY AND MIDDLE PORTIONS OF THE WEEK BEFORE STARTING TO
DRIFT EAST BY THE END OF THE WEEK. THE GEFS ENSEMBLE MEMBERS ALL
GENERALLY SUPPORT THIS SOLUTION AS WELL.

WITH THE TROUGH INITIALLY SHOWING UP AS A LOW AMPLITUDE WAVE MONDAY
AND THE BULK OF THE UPPER LEVEL SUPPORT FOR PCPN FARTHER NORTH INTO
THE PAC NW...WE HAVE JUST SOME SLIGHT CHANCE TO LOW END CHANCE POPS
FOR THE FAR NORTHERN PORTIONS OF THE CWA MONDAY AND TUESDAY. HIGH
TEMPS SHOULD BE NEAR TO SLIGHTLY ABOVE AVERAGE AND WINDS WILL BE
STRONGER MONDAY ALONG AND SOUTH OF I-80.

BY WEDNESDAY THE TROUGH BECOMES MORE AMPLIFIED WITH SLIGHTLY COOLER
AIR ALOFT. THIS COULD PRODUCE POPS FARTHER SOUTH INTO THE SOUTHERN
1/3 OF THE CWA BUT FOR NOW WE DO NOT HAVE THIS NOTED IN THE
FORECAST. BE AWARE...THOUGH...AS WE PROGRESS CLOSER TO THE WED/THU
TIME FRAME POPS FOR THE SOUTHERN CWA MAY BE INTRODUCED. HIGH TEMPS
ARE LIKELY TO BE A LITTLE COOLER FOR WED AND THU BUT STILL AROUND
AVERAGE FOR EARLY JUNE. 20

&&

.AVIATION...

VFR CONDITIONS ARE EXPECTED THROUGH THE WEEKEND WITH FAIRLY LIGHT
WINDS THROUGH SATURDAY. EACH DAY COULD SEE GUSTIER LATE AFTERNOON
WINDS EAST OF THE SIERRA...TYPICAL FOR THE WARMER MONTHS. CONVECTION
IS ALSO A POSSIBILITY EACH DAY...MAINLY OVER THE FAR SOUTHERN AREAS
SOUTH OF A LINE FROM BRIDGEPORT TO YERINGTON TO AUSTIN. ANY
CONVECTION TODAY AND SATURDAY SHOULD BE ISOLATED ENOUGH THAT EVEN IF
THUNDER DOES DEVELOP STORMS COULD BE NAVIGATED AROUND.

BY SUNDAY AFTERNOON SURFACE WINDS WILL BE STRONGER WITH GUSTS TO
NEAR 30 KTS AND RIDGE GUSTS APPROACHING 50 KTS OR MORE. CLOUDS ALSO
INCREASE LATE SUNDAY BUT CIGS SHOULD REMAIN VFR. 20

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
240 AM PDT FRI MAY 29 2015

.SYNOPSIS...OUTSIDE OF A STRAY SHOWER OR THUNDERSTORM ACROSS THE
HIGHER ELEVATIONS OF THE SOUTHERN GREAT BASIN THIS AFTERNOON AND
EVENING DRY CONDITIONS ARE EXPECTED ACROSS THE AREA TODAY. THE
HOTTEST WEATHER OF THE YEAR SO FAR IS EXPECTED THIS WEEKEND.
TEMPERATURES WILL SLOWLY RETURN TO NEAR NORMAL BY THE MIDDLE OF NEXT
WEEK.
&&

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT.

CIRRUS WAS EXITING THE EASTERN PARTS OF THE AREA EARLY THIS MORNING
AS A JET STREAK PULLS ON EAST. ALTHOUGH RIDGING ALOFT WILL BUILD
INTO CALIFORNIA TODAY, MORE CIRRUS WILL SPILL IN OVER THE TOP OF THE
RIDGE INTO OUR AREA THIS AFTERNOON INTO TONIGHT. HOWEVER, IT SHOULD
NOT BE TOO EXTENSIVE.

WITH THE RIDGE BUILDING IN TODAY HIGH TEMPS WILL RISE A COUPLE OF
DEGREES FROM THURSDAY. WE ONCE AGAIN WENT WITH THE WARMER END OF
GUIDANCE WHICH WAS THE MAV (GFS). AT MCCARRAN AIRPORT TODAY WE ARE
FORECASTING A HIGH OF 99 BUT MANY SPOTS ON THE EAST SIDE OF THE LAS
VEGAS VALLEY WILL SEE TRIPLE DIGITS TODAY.

THERE IS STILL JUST ENOUGH MID-LEVEL MOISTURE IN PLACE AND A WEAK
RIPPLE NOTED IN THE 500 MB HEIGHTS PROGGED FOR THIS AFTERNOON OVER
THE SOUTHERN GREAT BASIN THAT AN ISOLATED SHOWER OR THUNDERSTORM MAY
POP WITH THE HEATING OF THE DAY MAINLY ACROSS NORTHERN LINCOLN AND
NORTHERN INYO COUNTIES. THIS ACTIVITY SHOULD END BY THIS EVENING AND
THE LATEST HRRR MODEL SUPPORTED THE CURRENT POPS.

EVEN WARMER (MAYBE HOTTER DEPENDING ON YOUR TAKE) IS EXPECTED THIS
WEEKEND ACROSS THE AREA AS THE RIDGE ALOFT BUILDS OVERHEAD ON
SATURDAY THEN GETS PUSHED EAST ON SUNDAY BY AN APPROACHING LONGWAVE
MID/UPPER LEVEL TROUGH. THIS WILL PUSH TEMPS UP A FEW DEGREES EACH
DAY WITH SUNDAY BEING THE WARMEST DAY AS WE GET ON THE BACK SIDE OF
THE RIDGE AND LOW-LEVEL MIXING INCREASES. WE CONTINUED TO SIDE THE
WARMER MAV FOR HIGH TEMPS WHICH PUTS LAS VEGAS AT THE FIRST TRIPLE
DIGITS OF THE YEAR AT MCCARRAN ON SATURDAY. THIS WILL PUT HIGH TEMPS
NEAR RECORD LEVELS ON SUNDAY IN LAS VEGAS (RECORD IS 104 SET IN
2002). OTHERWISE DRY CONDITIONS ARE EXPECTED AREA-WIDE THIS WEEKEND
WITH SLIGHTLY GUSTIER WINDS SUNDAY AFTERNOON AND EVENING FROM THE
SOUTH TO SOUTHWEST ESPECIALLY AROUND BARSTOW.

REMEMBER TO STAY HYDRATED THIS WEEKEND AND IF IN THE HIGHER
MOUNTAINS BE CAREFUL FOR THE IMPACTS OF SNOW MELT INCLUDING COLD AND
RAPID FLOWS IN STREAMS AND CREEKS AND MELTED SNOW REFREEZING AND
FORMING ICE ON TRAILS.

.LONG TERM...MONDAY THOUGH FRIDAY MORNING.

AFTER A SCORCHING WEEKEND GENERAL WEAK TROUGHING WILL TAKE OVER THE
WESTERN US...LEADING TO SOME SLIGHT COOLING WITH TEMPERATURES
RETURNING CLOSER TO NORMAL. LIFT AND MOISTURE ASSOCIATED WITH ANY
SHORTWAVE ACTIVITY MOVING THROUGH FLOW SHOULD REMAIN WELL NORTH OF
THE AREA...WITH ANY IMPACTS AROUND THE AREA LIMITED TO WIND AND HIGH
CLOUDS...ESPECIALLY ON MONDAY. BOTH THE GFS AND EURO HINT AT MORE
ENERGY COMING SOUTHWARD TOWARDS THE END OF NEXT WEEK.
&&

.AVIATION...FOR MCCARRAN...EXPECT WINDS TO FAVOR TYPICAL DIURNAL
DIRECTIONS THROUGH THIS EVENING. SPEEDS OF 8-12 KTS WITH GUSTS TO 14-
18 KTS ARE EXPECTED IN THE LATE AFTERNOON AND EARLY EVENING
OTHERWISE WINDS SHOULD MAINLY BE 8 KTS OR LESS. FEW-SCT CLOUDS AT
TIMES AOA 25K FEET. TEMPS WILL REACH OR EXCEED 100F BOTH SATURDAY
AND SUNDAY FOR A FEW HOURS DURING THE AFTERNOON AND EARLY EVENING.
OTHERWISE WINDS WILL FAVOR TYPICAL DIURNAL DIRECTIONAL TRENDS
THROUGH THE WEEKEND WITH SLIGHTLY HIGHER SPEEDS ON SUNDAY EVENING.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED SHRA/TSRA ARE EXPECTED AFTER 20Z TODAY THROUGH
AROUND 05Z SATURDAY ALONG AND NORTH OF KBIH-KBJN-KCDC LINE.
OTHERWISE EXPECT DRY CONDITIONS WITH WINDS FAVORING TYPICAL DIURNAL
DIRECTIONAL TRENDS AT 10 KTS OR LESS. DRY CONDITIONS ARE EXPECTED
AREA-WIDE THIS WEEKEND WITH WINDS AGAIN FAVORING TYPICAL DIURNAL
DIRECTIONAL TRENDS. SLIGHTLY HIGHER SPEEDS ARE EXPECTED SUNDAY
AFTERNOON AND EVENING WITH GUSTS OF 15-25 KTS POSSIBLE ESPECIALLY IN
AND AROUND KDAG.

VERY GOOD AGREEMENT ON THE LATEST RUN...ADVERTISING A CONTINUED
PROGRESSIVE SYNOPTIC PATTERN. DRIER AND WARMER CONDITIONS ARE
EXPECTED AS A LOW AMPLITUDE RIDGE AXIS TRANSLATES EAST THROUGH THE
STATE. THUNDERSTORM ACTIVITY WILL STILL BE PRESENT BUT MORE
LIMITED. THE BEST INSTABILITY TO TRIGGER STORMS TODAY WILL BE
ACROSS EASTERN NEVADA AS WELL AS ALONG THE HIGHWAY 50 CORRIDOR IN
CENTRAL NEVADA. FOR SATURDAY...AS THE RIDGE AXIS CROSSES THE
CWFA...CONVECTION WILL BE SUBDUED UP NORTH FOR THE MOST PART AND

.PREV DISCUSSION... /ISSUED AT 200 PM /

SYNOPSIS...NEVADA WILL ENJOY A STRONG WARMING TREND THROUGH
SUNDAY. A MUCH DRIER WEATHER PATTERN HAS ARRIVED...WITH ONLY
ISOLATED THUNDERSTORMS ACROSS CENTRAL NEVADA FRIDAY
AFTERNOON...AND ON THE HIGHER TERRAIN OF ELKO COUNTY SATURDAY
AFTERNOON.

SHORT TERM...TONIGHT THROUGH SATURDAY.

RESIDUAL BOUNDARY LAYER MOISTURE RESULTING IN AN EXTENSIVE CUMULUS
FIELD ACROSS NEVADA THIS AFTERNOON, WITH WEAK INSTABILITY YIELDING
A FEW SHOWERS AND LIGHTNING STRIKES ACROSS EASTERN NEVADA.
SUBSIDENT NW FLOW IS TAKING OVER BEHIND THE DEPARTING WYOMING
TROUGH, AND EXPECT ALL SHOWERS TO END AND CUMULUS TO DISSIPATE
RAPIDLY THIS EVENING. LOW TEMPERATURES NEAR LATE MAY NORMALS UNDER
A MOSTLY CLEAR SKY FRIDAY MORNING.

FRIDAY...HIGH PRESSURE AMPLIFIES OVER THE GREAT BASIN, WITH RISING
HEIGHTS AND WARMING TEMPERATURES. VALLEYS WILL WARM WELL INTO THE
70S, WITH THE WARMEST LOCALES IN THE SOUTHERN/WESTERN ZONES IN THE
LOWER 80S. WEAK INSTABILITY WILL YIELD A FEW THUNDERSTORMS ACROSS
THE SE ZONES FRIDAY AFTERNOON, SE OF A MANHATTAN-EUREKA-CURRIE
LINE. COVERAGE WILL BE LIMITED.

SATURDAY...THE WARMING TREND CONTINUES, AS HIGH PRESSURE CONTINUES
TO STRENGTHEN. HEIGHTS AND THICKNESSES RISE SUBSTANTIALLY
SATURDAY, WITH 500 MB HEIGHTS NEAR 584 DM AT ELKO BY 5 PM. EXPECT
THE WARMEST TEMPERATURES OF THE YEAR SO FAR, WITH LOW TO MID 80S
COMMON. THE WARMEST LOCALES, SUCH AS BATTLE MOUNTAIN, AND THE
LOWEST VALLEYS OF NYE COUNTY, WILL FLIRT WITH 90 DEGREES. THE
WARMEST TEMPERATURE AT ELKO SO FAR IN 2015 IS 81 DEGREES. WEAK
INSTABILITY WILL AGAIN DEVELOP OVER THE HIGHER TERRAIN OF ELKO
COUNTY SATURDAY AFTERNOON, FUELED BY THE TOASTY TEMPERATURES.
FOLLOWED THE NAM/ECMWF QPF PLACEMENT FOR THE POP GRIDS, BUT AGAIN
COVERAGE WILL BE VERY LIMITED. MOST OF US SIMPLY MUCH WARMER AND
MUCH DRIER. DID UNDERCUT MODEL GUIDANCE BY A COUPLE DEGREES
THROUGH SATURDAY, TO ACCOUNT FOR WET SOILS AND EVAPORATION OF
STANDING WATER.  TURNER

LONG TERM...SATURDAY NIGHT THROUGH NEXT THURSDAY. MODELS IN PRETTY
GOOD AGREEMENT THROUGH TUESDAY. AFTER TUESDAY ALL MODELS AGREEMENT
ON GENERAL TROUGH PATTERN OVER WESTERN US...HOWEVER DIFFER ON LOCATION AND
STRENGTH OF SHORTWAVES EMBEDDED IN THE PATTERN SO LOWER CONFIDENCE
AFTER TUESDAY.

SATURDAY NIGHT THROUGH MONDAY SOUTHWESTERLY FLOW WITH WEAK
SHORTWAVES EMBEDDED IN THE FLOW WILL KICK OFF MAINLY
AFTERNOON/EVENING THUNDERSTORMS. TEMPERATURES WILL ALSO BE WARMER
BUT HIGHER THAN NORMAL LOW LEVEL MOISTURE MAY KEEP TEMPERATURES DOWN
A DEGREE OR TWO. ONLY MADE MINOR CHANGES TO POPS WITH MOISTURE
AND LIFT IN PLACE ONLY THING TO NOTE IS FORECAST SOUNDINGS SHOW A BIT
OF A WARMER LAYER ABOVE 500MB SO CONVECTION MAY BE LIMITED TO HIGH TERRAIN
BUT STILL A FEW DAYS OUT AND MODELS MAY GET BETTER HANDLE ON UPPER
LEVEL TEMPS. WINDS WILL ALSO BE A BREEZY ON SUNDAY AND MONDAY
GUSTING UP TO 30 TO 35 MPH DUE TO STRONGER PRESSURE GRADIENT.

TUESDAY THROUGH THURSDAY UPPER LEVEL HEIGHTS DECREASE WITH SLIGHTLY
COOLER AIR AS PARENT LOW MOVES ACROSS WASHINGTON AND IDAHO WITH
TROUGH OVER THE GREAT BASIN THIS WILL BRING MORE SHOWERS AND
ISOLATED THUNDER ACROSS NORTHERN NEVADA. MADE SOME MINOR CHANGES TO
POPS AND SKY BUT WITH UNCERTAINTY WITH TIMING OF SHORTWAVES DID NOT
MAKE ANY MAJOR CHANGES.

AVIATION...ISOLATED THUNDERSTORM ACTIVITY WILL CONTINUE THROUGH THE

70S, WITH THE WARMEST LOCALES IN THE SOUTHERN/WESTERN ZONES IN THE
LOWER 80S. WEAK INSTABILITY WILL YIELD A FEW THUNDERSTORMS ACROSS
THE SE ZONES FRIDAY AFTERNOON, SE OF A MANHATTAN-EUREKA-CURRIE
LINE. COVERAGE WILL BE LIMITED.

SATURDAY...THE WARMING TREND CONTINUES, AS HIGH PRESSURE CONTINUES
TO STRENGTHEN. HEIGHTS AND THICKNESSES RISE SUBSTANTIALLY
SATURDAY, WITH 500 MB HEIGHTS NEAR 584 DM AT ELKO BY 5 PM. EXPECT
THE WARMEST TEMPERATURES OF THE YEAR SO FAR, WITH LOW TO MID 80S
COMMON. THE WARMEST LOCALES, SUCH AS BATTLE MOUNTAIN, AND THE
LOWEST VALLEYS OF NYE COUNTY, WILL FLIRT WITH 90 DEGREES. THE
WARMEST TEMPERATURE AT ELKO SO FAR IN 2015 IS 81 DEGREES. WEAK
INSTABILITY WILL AGAIN DEVELOP OVER THE HIGHER TERRAIN OF ELKO
COUNTY SATURDAY AFTERNOON, FUELED BY THE TOASTY TEMPERATURES.
FOLLOWED THE NAM/ECMWF QPF PLACEMENT FOR THE POP GRIDS, BUT AGAIN
COVERAGE WILL BE VERY LIMITED. MOST OF US SIMPLY MUCH WARMER AND
MUCH DRIER. DID UNDERCUT MODEL GUIDANCE BY A COUPLE DEGREES
THROUGH SATURDAY, TO ACCOUNT FOR WET SOILS AND EVAPORATION OF
STANDING WATER.  TURNER

LONG TERM...SATURDAY NIGHT THROUGH NEXT THURSDAY. MODELS IN PRETTY
GOOD AGREEMENT THROUGH TUESDAY. AFTER TUESDAY ALL MODELS AGREEMENT
ON GENERAL TROUGH PATTERN OVER WESTERN US...HOWEVER DIFFER ON LOCATION AND
STRENGTH OF SHORTWAVES EMBEDDED IN THE PATTERN SO LOWER CONFIDENCE
AFTER TUESDAY.

SATURDAY NIGHT THROUGH MONDAY SOUTHWESTERLY FLOW WITH WEAK
SHORTWAVES EMBEDDED IN THE FLOW WILL KICK OFF MAINLY
AFTERNOON/EVENING THUNDERSTORMS. TEMPERATURES WILL ALSO BE WARMER
BUT HIGHER THAN NORMAL LOW LEVEL MOISTURE MAY KEEP TEMPERATURES DOWN
A DEGREE OR TWO. ONLY MADE MINOR CHANGES TO POPS WITH MOISTURE
AND LIFT IN PLACE ONLY THING TO NOTE IS FORECAST SOUNDINGS SHOW A BIT
OF A WARMER LAYER ABOVE 500MB SO CONVECTION MAY BE LIMITED TO HIGH TERRAIN
BUT STILL A FEW DAYS OUT AND MODELS MAY GET BETTER HANDLE ON UPPER
LEVEL TEMPS. WINDS WILL ALSO BE A BREEZY ON SUNDAY AND MONDAY
GUSTING UP TO 30 TO 35 MPH DUE TO STRONGER PRESSURE GRADIENT.

TUESDAY THROUGH THURSDAY UPPER LEVEL HEIGHTS DECREASE WITH SLIGHTLY
COOLER AIR AS PARENT LOW MOVES ACROSS WASHINGTON AND IDAHO WITH
TROUGH OVER THE GREAT BASIN THIS WILL BRING MORE SHOWERS AND
ISOLATED THUNDER ACROSS NORTHERN NEVADA. MADE SOME MINOR CHANGES TO
POPS AND SKY BUT WITH UNCERTAINTY WITH TIMING OF SHORTWAVES DID NOT
MAKE ANY MAJOR CHANGES.

AVIATION...ISOLATED THUNDERSTORM ACTIVITY WILL CONTINUE THROUGH THE
EARLY EVENING WITH ABOUT 30 PERCENT CHANCE AT KELY AND ABOUT 10 TO 15
PERCENT CHANCE AT KEKO...OTHERWISE OTHER TAF SITES WILL BE VFR WITH
NO SIGNIFICANT ISSUES.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
634 PM PDT THU MAY 28 2015

.SYNOPSIS...ISOLATED SHOWERS OR THUNDERSTORMS WILL STILL BE POSSIBLE
THIS EVENING ACROSS THE HIGHER TERRAIN OF SOUTHERN NEVADA AND IN THE
EASTERN SIERRA. THE SHOWER ACTIVITY WILL BE EVEN LESS ON FRIDAY
AFTERNOON WITH DRY AND HOT CONDITIONS EXPECTED ACROSS THE ENTIRE
AREA ON SATURDAY AND SUNDAY. TEMPERATURES WILL MODERATE NEXT
WEEK...BUT CONTINUE TO REMAIN ABOVE NORMAL.
&&

.UPDATE...SATELLITE SHOWS A LARGE AREA OF HIGH CLOUDS MOVING
SOUTHEAST ACROSS THE AREA THIS EVENING ASSOCIATED WITH HIGH LEVEL
MOISTURE BEING PUSHED ACROSS THE AREA BY THE JET STREAM. INFRARED
SATELLITE SHOWS THE CIRRUS HAS ENHANCED OFF THE SPRING MOUNTAINS
OVER SOUTHERN CLARK COUNTY. IN ADDITION THE LEADING EDGE OF THE
CIRRUS WAS ALREADY WELL INTO SOUTHERN MOHAVE COUNTY. I ADJUSTED UP
SKY COVER OVER THE SOUTHEAST AREA FOR THE REST OF TONIGHT AS A
RESULT.

TODAY`S HIGH OF 97 IN LAS VEGAS MARKED THE FIRST TIME THE HIGH HAS
REACHED ABOVE NORMAL SINCE MAY 11TH WHEN IT WAS 88 (NORMAL THEN IS
87).

THE CURRENT FORECAST LOOKS GOOD AND NO CHANGES OTHERWISE ARE NEEDED
AWAY FROM SKY COVER TONIGHT.
&&

.PREVIOUS DISCUSSION...
ISSUED AT 235 PM PDT THY MAY 28 2015

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT.

TEMPERATURES ARE 3 TO 5 DEGREES WARMER IN COMPARISON TO THIS TIME
YESTERDAY AND THAT TREND WILL CONTINUE THE NEXT FEW DAYS. VISIBLE
SATELLITE IMAGERY SHOWS SOME CUMULUS DEVELOPMENT IN AN AREA OF WEAK
INSTABILITY ACROSS CENTRAL NYE AND LINCOLN COUNTIES. A FEW SHOWERS
ARE POSSIBLE THIS EVENING AND A LIGHTNING STRIKE OR TWO CANNOT BE
RULED OUT...ESPECIALLY ACROSS THE EASTERN PORTIONS OF LINCOLN
COUNTY. A BAND OF CIRRUS MOVING IN FROM CENTRAL AND NORTHERN
CALIFORNIA WILL PROVIDE SOME HIGH CLOUDS ACROSS MUCH OF THE AREA
DURING THE EVENING HOURS. A SLIGHT CHANCE OF SHOWERS ARE POSSIBLE
ONCE AGAIN TOMORROW AFTERNOON IN LINCOLN COUNTY...BUT OVERALL
COVERAGE WILL BE LESS THAN TODAY.

THE MAIN ISSUE OF THE FORECAST PERIOD WILL BE THE RAPID INCREASE IN
TEMPERATURES AS A STRONG RIDGE OF HIGH PRESSURE BUILDS INTO THE
AREA. HIGH TEMPERATURES TOMORROW ARE EXPECTED TO BE ON AVERAGE 25
DEGREES WARMER THAN THEY WERE JUST ONE WEEK AGO. TEMPERATURES ARE
EXPECTED TO BREAK ABOVE THE CENTURY FOR THE FIRST TIME OFFICIALLY IN
LAS VEGAS ON SATURDAY...WITH SUNDAY LOOKING TO BE THE WARMEST DAY OF
THE PERIOD. TEMPERATURES ARE EXPECTED TO REACH WITHIN A FEW DEGREES
OF RECORD LEVELS IN LOCATIONS LIKE LAS VEGAS...BARSTOW AND KINGMAN
ON SUNDAY.

ON ANOTHER NOTE...THE FIRST TROPICAL STORM OF THE SEASON HAS FORMED
IN THE EASTERN PACIFIC...ANDRES...WHICH IS FORECAST TO BECOME A
HURRICANE THIS EVENING. THE FORECAST KEEPS ANDRES WELL AWAY FROM THE
SOUTHWEST U.S.

.LONG TERM...MONDAY THOUGH THURSDAY NIGHT.

A SEASONAL WEEK SETTING UP FOR NEXT WEEK BEGINNING WITH A PACIFIC
SHORTWAVE MOVING INTO THE PAC NW MONDAY WHICH THEN SETS THE STAGE
FOR A WEEK DEFINED BY WEAK TROUGHING. THIS WILL BRING IN MORE
SEASONAL TYPE CONDITIONS FOR EARLY JUNE COMPARED TO THE LATE
JUNE/EARLY JULY TEMPERATURES EXPECTED OVER THE FINAL MAY WEEKEND.
ANY SHORTWAVE ENERGY MOVING THROUGH THE TROUGH PATTERN IS NOT
EXPECTED TO PRODUCE ANY ACCUMULATING PRECIPITATION ALTHOUGH ANY
DEEPENING IN ONE OF THESE PASSING SHORTWAVES COULD RESULT IN LIGHT
PRECIP OVER THE SIERRA AND SOUTHERN GREAT BASIN MOUNTAINS. MONDAY
LOOKS LIKE THE BREEZY DAY OF THE WEEK ALTHOUGH LOCAL AFTERNOON
BREEZES ARE LIKELY EACH DAY.

EVENING WITH SCT-BKN CLOUDS AOA 25K FEET TONIGHT. SIMILAR CONDITIONS
EXPECTED ON FRIDAY WITH LIGHT AND VARIABLE WINDS DURING THE
MORNING...BECOMING SOUTHEAST AT 10 KTS OR LESS IN THE AFTERNOON.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED SHRA/TSRA ENDING BY 05Z FRIDAY NORTH OF KIYK-
KDRA-KCDC LINE. GUSTY AND ERRATIC WINDS ARE POSSIBLE IN AND NEAR ANY
SHRA/TSRA WITH CIGS LOWERING TO 5K-8K FEET AND LOCAL MOUNTAIN
OBSCURATIONS POSSIBLE. OTHERWISE WINDS WILL FAVOR TYPICAL DIURNAL
DIRECTIONAL TRENDS AT 10 KTS OR LESS THIS EVENING. FEW-SCT CLOUDS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
200 PM PDT THU MAY 28 2015

.SYNOPSIS...NEVADA WILL ENJOY A STRONG WARMING TREND THROUGH
SUNDAY. A MUCH DRIER WEATHER PATTERN HAS ARRIVED...WITH ONLY
ISOLATED THUNDERSTORMS ACROSS CENTRAL NEVADA FRIDAY
AFTERNOON...AND ON THE HIGHER TERRAIN OF ELKO COUNTY SATURDAY
AFTERNOON.

&&

.SHORT TERM...TONIGHT THROUGH SATURDAY.

RESIDUAL BOUNDARY LAYER MOISTURE RESULTING IN AN EXTENSIVE CUMULUS
FIELD ACROSS NEVADA THIS AFTERNOON, WITH WEAK INSTABILITY YIELDING
A FEW SHOWERS AND LIGHTNING STRIKES ACROSS EASTERN NEVADA.
SUBSIDENT NW FLOW IS TAKING OVER BEHIND THE DEPARTING WYOMING
TROUGH, AND EXPECT ALL SHOWERS TO END AND CUMULUS TO DISSIPATE
RAPIDLY THIS EVENING. LOW TEMPERATURES NEAR LATE MAY NORMALS UNDER
A MOSTLY CLEAR SKY FRIDAY MORNING.

FRIDAY...HIGH PRESSURE AMPLIFIES OVER THE GREAT BASIN, WITH RISING
HEIGHTS AND WARMING TEMPERATURES. VALLEYS WILL WARM WELL INTO THE
70S, WITH THE WARMEST LOCALES IN THE SOUTHERN/WESTERN ZONES IN THE
LOWER 80S. WEAK INSTABILITY WILL YIELD A FEW THUNDERSTORMS ACROSS
THE SE ZONES FRIDAY AFTERNOON, SE OF A MANHATTAN-EUREKA-CURRIE
LINE. COVERAGE WILL BE LIMITED.

SATURDAY...THE WARMING TREND CONTINUES, AS HIGH PRESSURE CONTINUES
TO STRENGTHEN. HEIGHTS AND THICKNESSES RISE SUBSTANTIALLY
SATURDAY, WITH 500 MB HEIGHTS NEAR 584 DM AT ELKO BY 5 PM. EXPECT
THE WARMEST TEMPERATURES OF THE YEAR SO FAR, WITH LOW TO MID 80S
COMMON. THE WARMEST LOCALES, SUCH AS BATTLE MOUNTAIN, AND THE
LOWEST VALLEYS OF NYE COUNTY, WILL FLIRT WITH 90 DEGREES. THE
WARMEST TEMPERATURE AT ELKO SO FAR IN 2015 IS 81 DEGREES. WEAK
INSTABILITY WILL AGAIN DEVELOP OVER THE HIGHER TERRAIN OF ELKO
COUNTY SATURDAY AFTERNOON, FUELED BY THE TOASTY TEMPERATURES.
FOLLOWED THE NAM/ECMWF QPF PLACEMENT FOR THE POP GRIDS, BUT AGAIN
COVERAGE WILL BE VERY LIMITED. MOST OF US SIMPLY MUCH WARMER AND
MUCH DRIER. DID UNDERCUT MODEL GUIDANCE BY A COUPLE DEGREES
THROUGH SATURDAY, TO ACCOUNT FOR WET SOILS AND EVAPORATION OF
STANDING WATER.  TURNER


.LONG TERM...SATURDAY NIGHT THROUGH NEXT THURSDAY. MODELS IN PRETTY
GOOD AGREEMENT THROUGH TUESDAY. AFTER TUESDAY ALL MODELS AGREEMENT
ON GENERAL TROUGH PATTERN OVER WESTERN US...HOWEVER DIFFER ON LOCATION AND
STRENGTH OF SHORTWAVES EMBEDDED IN THE PATTERN SO LOWER CONFIDENCE
AFTER TUESDAY.

SATURDAY NIGHT THROUGH MONDAY SOUTHWESTERLY FLOW WITH WEAK
SHORTWAVES EMBEDDED IN THE FLOW WILL KICK OFF MAINLY
AFTERNOON/EVENING THUNDERSTORMS. TEMPERATURES WILL ALSO BE WARMER
BUT HIGHER THAN NORMAL LOW LEVEL MOISTURE MAY KEEP TEMPERATURES DOWN
A DEGREE OR TWO. ONLY MADE MINOR CHANGES TO POPS WITH MOISTURE
AND LIFT IN PLACE ONLY THING TO NOTE IS FORECAST SOUNDINGS SHOW A BIT
OF A WARMER LAYER ABOVE 500MB SO CONVECTION MAY BE LIMITED TO HIGH TERRAIN
BUT STILL A FEW DAYS OUT AND MODELS MAY GET BETTER HANDLE ON UPPER
LEVEL TEMPS. WINDS WILL ALSO BE A BREEZY ON SUNDAY AND MONDAY
GUSTING UP TO 30 TO 35 MPH DUE TO STRONGER PRESSURE GRADIENT.

TUESDAY THROUGH THURSDAY UPPER LEVEL HEIGHTS DECREASE WITH SLIGHTLY
COOLER AIR AS PARENT LOW MOVES ACROSS WASHINGTON AND IDAHO WITH
TROUGH OVER THE GREAT BASIN THIS WILL BRING MORE SHOWERS AND
ISOLATED THUNDER ACROSS NORTHERN NEVADA. MADE SOME MINOR CHANGES TO
POPS AND SKY BUT WITH UNCERTAINTY WITH TIMING OF SHORTWAVES DID NOT
MAKE ANY MAJOR CHANGES.

LINE. COVERAGE WILL BE LIMITED.

SATURDAY...THE WARMING TREND CONTINUES, AS HIGH PRESSURE CONTINUES
TO STRENGTHEN. HEIGHTS AND THICKNESSES RISE SUBSTANTIALLY
SATURDAY, WITH 500 MB HEIGHTS NEAR 584 DM AT ELKO BY 5 PM. EXPECT
THE WARMEST TEMPERATURES OF THE YEAR SO FAR, WITH LOW TO MID 80S
COMMON. THE WARMEST LOCALES, SUCH AS BATTLE MOUNTAIN, AND THE
LOWEST VALLEYS OF NYE COUNTY, WILL FLIRT WITH 90 DEGREES. THE
WARMEST TEMPERATURE AT ELKO SO FAR IN 2015 IS 81 DEGREES. WEAK
INSTABILITY WILL AGAIN DEVELOP OVER THE HIGHER TERRAIN OF ELKO
COUNTY SATURDAY AFTERNOON, FUELED BY THE TOASTY TEMPERATURES.
FOLLOWED THE NAM/ECMWF QPF PLACEMENT FOR THE POP GRIDS, BUT AGAIN
COVERAGE WILL BE VERY LIMITED. MOST OF US SIMPLY MUCH WARMER AND
MUCH DRIER. DID UNDERCUT MODEL GUIDANCE BY A COUPLE DEGREES

STANDING WATER.  TURNER


.LONG TERM...SATURDAY NIGHT THROUGH NEXT THURSDAY. MODELS IN PRETTY
GOOD AGREEMENT THROUGH TUESDAY. AFTER TUESDAY ALL MODELS AGREEMENT
ON GENERAL TROUGH PATTERN OVER WESTERN US...HOWEVER DIFFER ON LOCATION AND
STRENGTH OF SHORTWAVES EMBEDDED IN THE PATTERN SO LOWER CONFIDENCE
AFTER TUESDAY.

SATURDAY NIGHT THROUGH MONDAY SOUTHWESTERLY FLOW WITH WEAK
SHORTWAVES EMBEDDED IN THE FLOW WILL KICK OFF MAINLY
AFTERNOON/EVENING THUNDERSTORMS. TEMPERATURES WILL ALSO BE WARMER
BUT HIGHER THAN NORMAL LOW LEVEL MOISTURE MAY KEEP TEMPERATURES DOWN
A DEGREE OR TWO. ONLY MADE MINOR CHANGES TO POPS WITH MOISTURE
AND LIFT IN PLACE ONLY THING TO NOTE IS FORECAST SOUNDINGS SHOW A BIT
OF A WARMER LAYER ABOVE 500MB SO CONVECTION MAY BE LIMITED TO HIGH TERRAIN
BUT STILL A FEW DAYS OUT AND MODELS MAY GET BETTER HANDLE ON UPPER
LEVEL TEMPS. WINDS WILL ALSO BE A BREEZY ON SUNDAY AND MONDAY
GUSTING UP TO 30 TO 35 MPH DUE TO STRONGER PRESSURE GRADIENT.

TUESDAY THROUGH THURSDAY UPPER LEVEL HEIGHTS DECREASE WITH SLIGHTLY
COOLER AIR AS PARENT LOW MOVES ACROSS WASHINGTON AND IDAHO WITH
TROUGH OVER THE GREAT BASIN THIS WILL BRING MORE SHOWERS AND
ISOLATED THUNDER ACROSS NORTHERN NEVADA. MADE SOME MINOR CHANGES TO
POPS AND SKY BUT WITH UNCERTAINTY WITH TIMING OF SHORTWAVES DID NOT
MAKE ANY MAJOR CHANGES.

ISOLATED THUNDERSTORMS ACROSS CENTRAL NEVADA FRIDAY
AFTERNOON...AND ON THE HIGHER TERRAIN OF ELKO COUNTY SATURDAY
AFTERNOON.

RESIDUAL BOUNDARY LAYER MOISTURE RESULTING IN AN EXTENSIVE CUMULUS
FIELD ACROSS NEVADA THIS AFTERNOON, WITH WEAK INSTABILITY YIELDING
A FEW SHOWERS AND LIGHTNING STRIKES ACROSS EASTERN NEVADA.
SUBSIDENT NW FLOW IS TAKING OVER BEHIND THE DEPARTING WYOMING
TROUGH, AND EXPECT ALL SHOWERS TO END AND CUMULUS TO DISSIPATE
RAPIDLY THIS EVENING. LOW TEMPERATURES NEAR LATE MAY NORMALS UNDER
A MOSTLY CLEAR SKY FRIDAY MORNING.

FRIDAY...HIGH PRESSURE AMPLIFIES OVER THE GREAT BASIN, WITH RISING
HEIGHTS AND WARMING TEMPERATURES. VALLEYS WILL WARM WELL INTO THE
70S, WITH THE WARMEST LOCALES IN THE SOUTHERN/WESTERN ZONES IN THE
LOWER 80S. WEAK INSTABILITY WILL YIELD A FEW THUNDERSTORMS ACROSS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
130 PM PDT THU MAY 28 2015

.SYNOPSIS...

HIGH PRESSURE WILL BRING A WARMING TREND WITH TEMPERATURES WELL
ABOVE AVERAGE THROUGH THIS WEEKEND. A COLD FRONT WILL BRING GUSTY
WINDS SUNDAY INTO MONDAY WITH TEMPERATURES COOLING TO NEAR NORMAL BY
MONDAY. A FEW THUNDERSTORMS ARE POSSIBLE SUNDAY NIGHT AND MONDAY,
MAINLY NORTH OF INTERSTATE 80.

&&

.SHORT TERM...

RIDGE OF HIGH PRESSURE WILL CONTINUE TO STRENGTHEN OVER THE WEST
COAST THIS WEEKEND WITH WARMING TEMPERATURES. A FEW DEGREES OF
WARMING ARE EXPECTED FOR FRIDAY AND AGAIN ON SATURDAY WITH TEMPS
PEAKING OUT AROUND 90 DEGREES IN THE LOWER VALLEYS AND UPPER 70S AND
LOW 80S IN THE SIERRA. DRIER AIR AND SUBSIDENCE ALOFT WILL KEEP ANY
THUNDERSTORMS OUT OF THE FORECAST FRIDAY THROUGH SUNDAY. ANYONE
PLANNING TO GO SWIMMING IN THE LOCAL LAKES AND RIVERS THIS WEEKEND
SHOULD BE AWARE OF COLD WATER TEMPERATURES THIS TIME OF YEAR IN THE
50S.

BY SUNDAY, A FAST MOVING SHORTWAVE TROUGH APPROACHES NORTHERN
CALIFORNIA WITH A STRONG ASSOCIATED COLD FRONT. THE JET WILL DRIP
ACROSS THE RENO-TAHOE AREA LATE SUNDAY WITH 700MB WINDS INCREASING
TO AROUND 40-45 KTS. EXPECT TO SEE INCREASING WINDS SUNDAY AFTERNOON
WITH GUSTS UP TO 40 MPH LIKELY IN THE VALLEYS, ESPECIALLY ALONG THE
HIGHWAY 395 CORRIDOR FROM MINDEN NORTHWARD TO SUSANVILLE. NO FIRE
WEATHER STATEMENTS ARE EXPECTED AT THIS TIME, DUE TO RECENT RAINFALL
AND HIGHER MOISTURE IN THE NATIVE VEGETATION. LAKE WIND ADVISORIES
WILL LIKELY BE NEEDED ON SUNDAY IF MODEL TRENDS CONTINUE. CHOPPY
CONDITIONS WOULD BE EXPECTED FOR LOCAL AREA LAKES, INCLUDING TAHOE
AND PYRAMID.

RIDGE WINDS WILL INCREASE SHARPLY SUNDAY NIGHT AS THE COLD FRONT
PASSES THROUGH THE AREA. THERE IS A SLIGHT CHANCE OF THUNDERSTORMS
SUNDAY NIGHT, ALTHOUGH THE BEST CHANCES FOR SHOWERS WILL BE MONDAY
AS THE UNSTABLE AIR PUSHES IN. HOON

.LONG TERM...MONDAY THROUGH THURSDAY...

LITTLE CHANGE WAS NEEDED TO THE ONGOING FORECAST AS MODELS ARE STILL
IN GOOD AGREEMENT BRINGING A TROUGH AND STRONG COLD FRONT THROUGH
THE REGION BY MONDAY. THIS WILL BRING BREEZY WEST WINDS TO THE AREA
WITH GUSTS OF 35 TO 45 MPH POSSIBLE ON MONDAY. THE TROUGH COMES INTO
THE SIERRA AND NORTHWEST NEVADA WITH A NEGATIVE TILT, WHICH IS
FAVORABLE FOR INCREASED THUNDERSTORM DYNAMICS. HOWEVER, THE DEEPEST
MOISTURE REMAINS NORTH INTO OREGON, SO HAVE ONLY LOW END CHANCES FOR
SHOWERS AND THUNDERSTORMS FOR AREAS MAINLY NORTH OF SUSANVILLE-
LOVELOCK LINE. A FEW SHORTWAVES MOVE THROUGH THE FLOW, KEEPING
SLIGHT CHANCES FOR SHOWERS NORTH OF INTERSTATE 80 THROUGH TUESDAY
BEFORE THE REGION RETURNS TO DRY WESTERLY FLOW.

LONG RANGE MODELS AND MOST ENSEMBLE MEMBERS HAVE CONTINUED THE TREND
TOWARD GENERAL TROUGHINESS OVER THE WEST LASTING THROUGH THE WORK
WEEK, WHICH IS DIFFERENT THAN THE WEAK RIDGING SHOWING UP YESTERDAY.
THEREFORE, WILL KEEP TEMPERATURES NEAR NORMAL FOR THE WEEK, BUT WITH
LACK OF MOISTURE BEYOND TUESDAY, THE FORECAST WILL REMAIN DRY
WEDNESDAY AND THURSDAY. DJ

&&

.AVIATION...

WIDESPREAD VFR CONDITIONS CAN BE EXPECTED ACROSS THE SIERRA AND
WESTERN NEVADA THIS WEEKEND WITH A RIDGE OF HIGH PRESSURE ACROSS THE
REGION. AS DRIER AIR WORKS INTO THE AREA, CHANCES FOR ANY FOG
DEVELOPMENT IN THE SIERRA CONTINUE TO LESSEN. THERE WAS ONLY PATCHY
FOG AROUND KTRK LAST NIGHT, AND THIS MAY BE THE CASE ONCE AGAIN
TONIGHT, BUT CHANCES ARE ONLY AROUND 40 PERCENT AND THEREFORE WILL
LEAVE OUT OF THE TAF. CHANCES FOR FOG SAT/SUN MORNINGS IN SIERRA
VALLEYS ARE AROUND 10 PERCENT.

WINDS WILL BE LIGHT THROUGH SATURDAY, BUT THEN BECOME GUSTY FOR
SUNDAY AND MONDAY AHEAD OF A COLD FRONT. GUSTS OF 30 TO 40 KTS CAN
BE EXPECTED BOTH AFTERNOONS AREA-WIDE WITH TURBULENCE LIKELY ON THE
LEE SIDE OF THE SIERRA. DJ

BEFORE THE REGION RETURNS TO DRY WESTERLY FLOW.

LONG RANGE MODELS AND MOST ENSEMBLE MEMBERS HAVE CONTINUED THE TREND
TOWARD GENERAL TROUGHINESS OVER THE WEST LASTING THROUGH THE WORK
WEEK, WHICH IS DIFFERENT THAN THE WEAK RIDGING SHOWING UP YESTERDAY.
THEREFORE, WILL KEEP TEMPERATURES NEAR NORMAL FOR THE WEEK, BUT WITH
LACK OF MOISTURE BEYOND TUESDAY, THE FORECAST WILL REMAIN DRY
WEDNESDAY AND THURSDAY. DJ

&&

.AVIATION...

WIDESPREAD VFR CONDITIONS CAN BE EXPECTED ACROSS THE SIERRA AND
WESTERN NEVADA THIS WEEKEND WITH A RIDGE OF HIGH PRESSURE ACROSS THE
REGION. AS DRIER AIR WORKS INTO THE AREA, CHANCES FOR ANY FOG
DEVELOPMENT IN THE SIERRA CONTINUE TO LESSEN. THERE WAS ONLY PATCHY
FOG AROUND KTRK LAST NIGHT, AND THIS MAY BE THE CASE ONCE AGAIN
TONIGHT, BUT CHANCES ARE ONLY AROUND 40 PERCENT AND THEREFORE WILL
LEAVE OUT OF THE TAF. CHANCES FOR FOG SAT/SUN MORNINGS IN SIERRA
VALLEYS ARE AROUND 10 PERCENT.

WINDS WILL BE LIGHT THROUGH SATURDAY, BUT THEN BECOME GUSTY FOR
SUNDAY AND MONDAY AHEAD OF A COLD FRONT. GUSTS OF 30 TO 40 KTS CAN
BE EXPECTED BOTH AFTERNOONS AREA-WIDE WITH TURBULENCE LIKELY ON THE
LEE SIDE OF THE SIERRA. DJ

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
1235 PM PDT THU MAY 28 2015

.SYNOPSIS...WARMER AND DRIER WEATHER IS EXPECTED ACROSS NEVADA
FRIDAY THROUGH THE UPCOMING WEEKEND...WITH ONLY ISOLATED
THUNDERSTORMS EXPECTED.

&&

.UPDATE...ISOLATED SHOWERS HAVE DEVELOPED AS FAR WEST AS ELKO, SO
UPDATED GRIDS TO PULL POPS WEST A BIT. ALSO INCREASED CLOUD COVER
WITH EXTENSIVE CUMULUS FIELD. NO OTHER CHANGES.  TURNER

&&

.PREV DISCUSSION... /ISSUED AT 215 AM /

SYNOPSIS...MOTORISTS MAY ENCOUNTER SOME PATCHES OF FOG THIS
MORNING. AS TEMPERATURES WARM INTO THE 80S LATE THIS WEEK AND OVER
THE WEEKEND...CONDITIONS WILL GENERALLY BECOME DRIER. HOWEVER
THERE WILL BE THE POSSIBILITY OF A THUNDERSTORM OR TWO EACH DAY.

SHORT TERM...TODAY THROUGH FRIDAY. SOME PATCHY FOG MAY DEVELOP
THIS MORNING AS THINGS SETTLE DOWN A BIT. HOWEVER THERE ARE
STILL A FEW REMNANT SHOWERS ACROSS NORTHERN NEVADA THIS MORNING
AS WELL AS SOME THUNDERSTORM ACTIVITY OVER ELKO COUNTY. THE MODELS
SEEM TO BE IN VERY GOOD AGREEMENT WITH THE PROJECTED MOVEMENT EAST
OF A TROUGH OF LOW PRESSURE AND AN INCOMING RIDGE PATTERN.

TODAY THROUGH THIS EVENING. AS THE TROUGH SLOWLY EXITS...ONE MORE
SHORT WAVE LOBE WILL INSTIGATE SOME CONVECTION OVER EASTERN NEVADA
THIS AFTERNOON JUST AS A SHORT WAVE RIDGE AXIS BEGINS TO MOVE
INTO COASTAL CALIFORNIA. THE RIDGE IS EXPECTED TO AMPLIFY QUICKLY
LATE AFTERNOON AND EARLY EVENING AND SPREAD ITS INFLUENCE EASTWARD
THUS CONVECTION SHOULD SHUT OFF RATHER ABRUPTLY LATE THIS AFTERNOON
OR VERY EARLY THIS EVENING. WESTERN NEVADA WILL BEGIN TO WARM
SUBSTANTIALLY DUE TO THE SOUTHERLY PUSH OF DRIER AIR.

MIDNIGHT TONIGHT THROUGH FRIDAY. THE UPPER LEVEL PATTERN REMAINS
PROGRESSIVE. ALTHOUGH THE RIDGE WILL MOVE OVER THE STATE
FRIDAY TO BRING WARMER CONDITIONS...IT WILL ALSO UNDERGO DE-
AMPLIFICATION...SO DRYING WILL BE LIMITED. THERE WILL BE ENOUGH
MOISTURE UNDER THE RIDGE TO ALLOW FOR SOME THUNDERSTORM
DEVELOPMENT AGAIN FRIDAY AFTERNOON OVER EASTERN NEVADA AS WELL AS
ALONG THE HIGHWAY 50 CORRIDOR IN CENTRAL NEVADA.

LONG TERM...FRIDAY NIGHT THROUGH THURSDAY. THE MODELS ARE IN FAIRLY
GOOD AGREEMENT THROUGH THE SUN-MON TIME FRAME.

RIDGE BUILDS IN FRIDAY AND SATURDAY WITH WARMING AND "DRYING"
CONDITIONS. RESIDUAL MOISTURE WILL ALLOW FOR SOME AFTERNOON BUILDUPS
IN CENTRAL AND NORTHEASTERN NEVADA. PERHAPS EVEN AN ISOLATED
SHOWER/STORM. NOT MUCH IN THE WAY OF PRECIP EXPECTED.

SUNDAY AND MONDAY...BROAD SW FLOW SPREADS ACROSS THE AREA. RH WILL
DROP AND WINDS WILL INCREASE. A FEW AFTERNOON SHOWERS/STORMS WILL BE
POSSIBLE ACROSS NORTHERN NEVADA...BUT AGAIN..NOT EXPECTING ANY REAL
PRECIP. THIS WILL BE THE WARMEST WEEKEND YET. MANY PLACES WILL BE IN
THE 80S...WITH SOME VALLEY LOCATIONS BELOW 5000FT AROUND 90.

HEADING INTO THE MIDDLE PART OF NEXT WEEK...A TROUGH WILL SLOWLY
WOBBLE ACROSS NORTHERN NEVADA. THIS WILL PROVIDE THE BEST CHANCE IN
THE LONG TERM FOR BENEFICIAL AMOUNTS OF RAIN. THE LATEST SUITE OF
MODEL RUNS SHOW A MORE NORTHERN TRACK WITH THE UPPER LEVEL STORM
SYSTEM. DECIDED TO TWEAK POPS DOWN JUST A BIT...BUT DUE TO
UNCERTAINTY...DID NOT WANT TO MAKE ANY SIGNIFICANT CHANGES. STILL
KEPT ISOLATED SHOWERS/STORMS FOR NORTHERN NEVADA. GIVEN THE CURRENT
MODEL TRENDS...WOULD NOT BE SHOCKED TO SEE THIS CONTINUE TO SHIFT
NORTHWARD. THIS SOLUTION WOULD KEEP NEVADA DRY AND BREEZY.

AVIATION...VFR IS EXPECTED AT ALL TAF SITES THROUGH THE NEXT 24
HRS. A FEW -SHRA/-TS STILL PERSIST ACROSS NORTHERN NV AT THIS HOUR.
EXPECT THIS ACTIVITY TO CONTINUE MOVING EAST AND WEAKEN. LATER TODAY
(THU) EXPECT MUCH DRIER CONDITIONS. EXPECT SOME BUILDUP OF CUMULUS
CLOUDS ON MTN RANGES. KELY WILL HAVE A CHANCE AT VCTS...BUT CHANCES
OF A TS IS LESS THAN 20% IMPACTING THE AIRPORT.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1049 AM PDT THU MAY 28 2015

.SYNOPSIS...A FEW AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS
WILL BE AROUND TODAY AND POSSIBLY ON FRIDAY OVER THE SOUTHERN GREAT
BASIN. OTHERWISE EXPECT DRY CONDITIONS WITH A WARMING TREND THROUGH
THE WEEKEND. THE WARMEST WEATHER OF THE YEAR SO FAR IS EXPECTED THIS
WEEKEND. TEMPERATURES SHOULD GRADUALLY LOWER TO NEAR NORMAL BY THE
MIDDLE OF NEXT WEEK.
&&

.UPDATE...FORECAST IS ON TRACK AND NO UPDATES ARE PLANNED AT THIS
TIME. THE BEST OPPORTUNITY FOR SEEING A SHOWER OR ISOLATED
THUNDERSTORM WILL BE OVER THE PANHANDLE OF LINCOLN COUNTY THIS
AFTERNOON...WHERE SOME MARGINAL INSTABILITY WILL BE IN PLACE.  TODAY
WILL BE THE FIRST DAY WITH ABOVE NORMAL TEMPERATURES IN QUITE A
WHILE.  THE MAIN FORECAST ISSUE WILL BE THE WEEKEND HEAT. THE RECORD
HIGH IN LAS VEGAS ON SUNDAY IS 104 AND WE WILL BE VERY CLOSE TO
REACHING THAT VALUE.
&&

.PREVIOUS DISCUSSION...
235 AM PDT THU MAY 28 2015

.SHORT TERM...TODAY THROUGH SATURDAY NIGHT.

THE PATTERN ALOFT WILL TRANSITION TODAY TO ONE THAT IS WARMER AND
DRIER. A MID/UPPER LEVEL TROUGH THAT HAS BEEN AROUND OVER THE AREA
FOR MOST OF MAY WILL TRANSITION TO THE EAST TODAY OPENING THE DOOR
FOR A RARE RIDGE ALOFT TO BUILD INTO CALIFORNIA FROM THE PACIFIC.
THERE IS STILL ENOUGH MID-LEVEL MOISTURE AND A SMALL RIPPLE
(WEAKNESS) NOTED IN THE MODEL 500 MB HEIGHTS IN THE WAKE OF THIS
TROUGH ACROSS SOUTH-CENTRAL NEVADA THAT WITH THE HEATING OF THE DAY
A FEW SHOWERS AND THUNDERSTORMS COULD POP OVER THE SOUTHERN GREAT
BASIN FROM NORTHERN INYO TO LINCOLN COUNTIES. THE COVERAGE OF
ACTIVITY SHOULD BE A LITTLE LESS THAN YESTERDAY AND BASED ON THE
LATEST HRRR AND LOCAL ARW AND NMM 4 KM MODELS NO CHANGES WERE MADE
TO POPS. LIGHTNING, WIND GUSTS TO 45 MPH AND DOWNPOURS WILL AGAIN BE
THE MAIN HAZARDS WITH ANY STRONGER THUNDERSTORMS. OTHERWISE, EXPECT
A DRY DAY WITH CIRRUS SPILLING IN FROM THE NORTHWEST THROUGH THE DAY
COURTESY OF THE JET STREAM FEEDING IN HIGH LEVEL MOISTURE. TEMPS
WILL WARM A FEW MORE DEGREES AND THE WARMER MAV (GFS) NUMBERS WERE
MAINLY USED WITH ADDITIONAL TWEAKS BASED ON WHAT WE SAW YESTERDAY.

CIRRUS SHOULD CROSS THE AREA TONIGHT RESULTING IN A PARTLY CLOUDY
SKY ON AVERAGE. THE RIDGE ALOFT WILL BUILD FURTHER INLAND TOMORROW.
AGAIN, THE ARW AND NMM AS WELL AS THE WRF HINT THAT FEW SHOWERS MAY
TRY TO GO IN THE AFTERNOON AND EVENING OVER THE SOUTHERN SIERRA AND
IN NORTHERN LINCOLN COUNTY. LOW END SLIGHT CHANCE POPS WERE KEPT IN
FOR THIS AS THIS WILL COME DOWN TO MAINLY MOISTURE FROM SNOWMELT
SUBLIMATING AND TERRAIN HEATING DRIVING CONVECTION. OTHERWISE,
EXPECT TEMPS TO WARM A FEW MORE DEGREES AND AGAIN I WENT WITH THE
WARMER MAV.

SATURDAY LOOKS DRY AND RELATIVELY CLOUD-FREE AS THE RIDGE AXIS
BECOMES CENTERED OVER CALIFORNIA. HIGHS SHOULD WARM A FEW DEGREES
WHICH WOULD GIVE LAS VEGAS THE FIRST TRIPLE DIGIT HIGH OF THE YEAR
AT MCCARRAN THOUGH SOME EASTERN PARTS OF THE LAS VEGAS VALLEY WILL
LIKELY SEE THAT TODAY OR ON FRIDAY. TEMPS WILL NOT COOL OFF AS MUCH
AT NIGHT AS THE HEAT ISLAND KICKS IN AND LOWS FAIL TO DROP BELOW THE
MID 70S. OUR HIGH LAST FRIDAY WAS ONLY 74 IN CASE YOU FORGOT.

AS A REMINDER, CHECK YOUR AIR CONDITIONER AND STAY HYDRATED IF YOU
HAVE ANY WEEKEND PLANS. IN ADDITION, SNOW AND ICE MELT WILL CREATE
HIGH ELEVATION HAZARDS ESPECIALLY IN THE SIERRA. WE HAVE ISSUED A
GRAPHIC TO HIGHLIGHT THIS.

.LONG TERM...SUNDAY THOUGH THURSDAY MORNING.

HIGH PRESSURE OVER THE WESTERN US WILL DOMINATE THIS PERIOD WITH HOT
TEMPERATURES UNTIL MONDAY WHEN THE RIDGE BEGINS TO FLATTEN A BIT AS
AN UPPER LEVEL TROUGH APPROACHES THE PACIFIC NORTHWEST...HELPING TO
TAMPER TEMPS A FEW DEGREES AND INCREASE WINDS ACROSS THE AREA. THE
TROUGH WILL PASS BY WELL TO THE NORTH KEEPING CHANCES OF PRECIP WELL
NORTH...WITH ONLY SLIGHTLY COOLER TEMPS...NEAR NORMAL FOR THIS TIME
OF YEAR...AND SOME HIGH CLOUDS EXPECTED FOR THE AREA FOR TUESDAY AND
WEDNESDAY. BY THURSDAY ANOTHER TROUGH IS PROGGED TO DROP DOWN THE
BACK SIDE OF THE DEPARTING TROUGH FROM WEDNESDAY. THE GFS AND ECMWF
HANDLE THIS TROUGH DIFFERENTLY...WITH THE ECMWF BEING THE SLOWER OF
THE TWO AND DIGGING IT ALONG THE COAST IN CONTRAST TO THE GFS WHICH
IS MORE PROGRESSIVE AND FURTHER INLAND. BOTH MODELS KEEP DYNAMICS
AND MOISTURE CONFINED TO THE SIERRA AND SOUTHERN GREAT BASIN AT THIS
POINT.
&&

.AVIATION...FOR MCCARRAN...WINDS WILL FAVOR TYPICAL DIURNAL
DIRECTIONAL TRENDS AT 10 KTS OR LESS THROUGH THIS EVENING WITH THE
HIGHEST SPEEDS IN THE LATE AFTERNOON AND EVENING. FEW-SCT CLOUDS AOA
12K FEET IN THE AFTERNOON WITH SCT-BKN CLOUDS AOA 25K FEET TONIGHT.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED SHRA/TSRA AFTER 20Z THURSDAY AND ENDING BY 05Z
FRIDAY NORTH OF KIYK-KDRA-KCDC LINE. GUSTY AND ERRATIC WINDS ARE

AND LOCAL MOUNTAIN OBSCURATIONS POSSIBLE. OTHERWISE WINDS WILL FAVOR
TYPICAL DIURNAL DIRECTIONAL TRENDS AT 10 KTS OR LESS THROUGH

.SYNOPSIS...

HIGH PRESSURE WILL BRING A WARMING TREND WITH TEMPERATURES WELL
ABOVE AVERAGE THROUGH THIS WEEKEND. A TROUGH WILL BRING BREEZY
CONDITIONS SUNDAY AND MONDAY WITH TEMPERATURES COOLING TO NEAR
NORMAL BY MONDAY. A FEW THUNDERSTORMS ARE POSSIBLE SUNDAY NIGHT
AND MONDAY, MAINLY NORTH OF INTERSTATE 80.

&&

.SHORT TERM...

UPPER LEVEL RIDGE AXIS OFF THE CALIFORNIA COAST MOVES INLAND TODAY
WITH WARMING TREND CONTINUING. SOME HIGH LEVEL MOISTURE WILL ALSO
SPREAD ACROSS THE REGION DURING THE DAY AS WEAK UPPER LEVEL
IMPULSE MOVES THROUGH THE RIDGE. ANY FORCING ASSOCIATED WITH THIS
FEATURE APPEARS TO BE TOO WEAK AND ARRIVING TOO LATE IN THE DAY FOR
TRIGGERING THUNDERSTORMS. SOME CUMULUS BUILDUPS AND BRIEF SHOWERS
MAY OCCUR LATER TODAY NORTH OF SUSANVILLE-GERLACH, BUT WITH
COVERAGE LIKELY TO BE SPARSE AND MEANINGFUL PRECIPITATION NOT
EXPECTED, WE DIDN`T ADD MENTION OF PRECIP TO NORTHEAST CA-
NORTHWEST NV AT THIS TIME.

FOR FRIDAY AND SATURDAY, RIDGE AXIS MOVES SLOWLY EAST ACROSS
NEVADA, BRINGING EVEN WARMER TEMPERATURES TO THE REGION. BY
SATURDAY, INCREASING SOUTHWEST FLOW ALOFT WILL LEAD TO IMPROVED
MIXING, WITH HIGHS NEAR OR ABOVE 90 DEGREES FOR MANY WESTERN NV
VALLEYS. DESPITE THE WARMER SURFACE TEMPS, FURTHER LOW LEVEL
DRYING AND WARMING ALOFT WILL LIMIT INSTABILITY AND PREVENT
THUNDERSTORM DEVELOPMENT BOTH DAYS. MJD

.LONG TERM...SUNDAY THROUGH WEDNESDAY...

FEW CHANGES MADE TO THE LONG TERM FORECAST AS THE RIDGE MOVES EAST
SUNDAY WITH LOW PRESSURE MOVING INTO THE PACIFIC NORTHWEST MONDAY.
THE FLOW THEN BECOMES MORE ZONAL WITH WEAK SHORT WAVES BRUSHING
AREAS NEAR THE OREGON BORDER. WITH THE LOW SLIGHTLY SLOWER AND
LITTLE INSTABILITY SHOWING UP AHEAD OF IT WITH STRONG SOUTHWEST
FLOW, HAVE REMOVED THE THREAT OF CONVECTION SUNDAY. IT APPEARS THE
BEST CHANCE WOULD BE SUNDAY NIGHT AS DYNAMICS IMPROVE, BUT EVEN
THEN, IT MAY BE FARTHER EAST OVER NORTH CENTRAL NEVADA. THE OTHER
CHANGE MADE SUNDAY WAS TO INCREASE THE WIND AS THE LATEST GUIDANCE
HAS STRONGER SFC THERMAL/PRESSURE GRADIENTS AND WINDS ALOFT. COULD
SEE GUSTS APPROACH 40-45 MPH IF THESE RUNS REMAIN CONSISTENT.

AS THE LOW MOVES INTO OREGON MONDAY AND PUSHES A STRONG COLD FRONT
THROUGH, IT WILL REMAIN BREEZY ALONG WITH COOLER TEMPERATURES. WITH
SOME MOISTURE NORTH OF I-80 A FEW SHOWERS REMAIN POSSIBLE INTO
TUESDAY, AS WEAK SHORT WAVES EMBEDDED IN THE FLOW MOVE THROUGH

.SYNOPSIS...A FEW AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS
WILL BE AROUND TODAY AND POSSIBLY ON FRIDAY OVER THE SOUTHERN GREAT
BASIN. OTHERWISE EXPECT DRY CONDITIONS WITH A WARMING TREND THROUGH
THE WEEKEND. THE WARMEST WEATHER OF THE YEAR SO FAR IS EXPECTED THIS
WEEKEND. TEMPERATURES SHOULD GRADUALLY LOWER TO NEAR NORMAL BY THE
MIDDLE OF NEXT WEEK.
&&

.SHORT TERM...TODAY THROUGH SATURDAY NIGHT.

THE PATTERN ALOFT WILL TRANSITION TODAY TO ONE THAT IS WARMER AND
DRIER. A MID/UPPER LEVEL TROUGH THAT HAS BEEN AROUND OVER THE AREA
FOR MOST OF MAY WILL TRANSITION TO THE EAST TODAY OPENING THE DOOR
FOR A RARE RIDGE ALOFT TO BUILD INTO CALIFORNIA FROM THE PACIFIC.
THERE IS STILL ENOUGH MID-LEVEL MOISTURE AND A SMALL RIPPLE
(WEAKNESS) NOTED IN THE MODEL 500 MB HEIGHTS IN THE WAKE OF THIS
TROUGH ACROSS SOUTH-CENTRAL NEVADA THAT WITH THE HEATING OF THE DAY
A FEW SHOWERS AND THUNDERSTORMS COULD POP OVER THE SOUTHERN GREAT
BASIN FROM NORTHERN INYO TO LINCOLN COUNTIES. THE COVERAGE OF
ACTIVITY SHOULD BE A LITTLE LESS THAN YESTERDAY AND BASED ON THE
LATEST HRRR AND LOCAL ARW AND NMM 4 KM MODELS NO CHANGES WERE MADE
TO POPS. LIGHTNING, WIND GUSTS TO 45 MPH AND DOWNPOURS WILL AGAIN BE
THE MAIN HAZARDS WITH ANY STRONGER THUNDERSTORMS. OTHERWISE, EXPECT
A DRY DAY WITH CIRRUS SPILLING IN FROM THE NORTHWEST THROUGH THE DAY
COURTESY OF THE JET STREAM FEEDING IN HIGH LEVEL MOISTURE. TEMPS
WILL WARM A FEW MORE DEGREES AND THE WARMER MAV (GFS) NUMBERS WERE
MAINLY USED WITH ADDITIONAL TWEAKS BASED ON WHAT WE SAW YESTERDAY.

CIRRUS SHOULD CROSS THE AREA TONIGHT RESULTING IN A PARTLY CLOUDY
SKY ON AVERAGE. THE RIDGE ALOFT WILL BUILD FURTHER INLAND TOMORROW.
AGAIN, THE ARW AND NMM AS WELL AS THE WRF HINT THAT FEW SHOWERS MAY
TRY TO GO IN THE AFTERNOON AND EVENING OVER THE SOUTHERN SIERRA AND
IN NORTHERN LINCOLN COUNTY. LOW END SLIGHT CHANCE POPS WERE KEPT IN
FOR THIS AS THIS WILL COME DOWN TO MAINLY MOISTURE FROM SNOWMELT
SUBLIMATING AND TERRAIN HEATING DRIVING CONVECTION. OTHERWISE,
EXPECT TEMPS TO WARM A FEW MORE DEGREES AND AGAIN I WENT WITH THE
WARMER MAV.

SATURDAY LOOKS DRY AND RELATIVELY CLOUD-FREE AS THE RIDGE AXIS
BECOMES CENTERED OVER CALIFORNIA. HIGHS SHOULD WARM A FEW DEGREES
WHICH WOULD GIVE LAS VEGAS THE FIRST TRIPLE DIGIT HIGH OF THE YEAR
AT MCCARRAN THOUGH SOME EASTERN PARTS OF THE LAS VEGAS VALLEY WILL
LIKELY SEE THAT TODAY OR ON FRIDAY. TEMPS WILL NOT COOL OFF AS MUCH
AT NIGHT AS THE HEAT ISLAND KICKS IN AND LOWS FAIL TO DROP BELOW THE
MID 70S. OUR HIGH LAST FRIDAY WAS ONLY 74 IN CASE YOU FORGOT.

AS A REMINDER, CHECK YOUR AIR CONDITIONER AND STAY HYDRATED IF YOU
HAVE ANY WEEKEND PLANS. IN ADDITION, SNOW AND ICE MELT WILL CREATE
HIGH ELEVATION HAZARDS ESPECIALLY IN THE SIERRA. WE HAVE ISSUED A
GRAPHIC TO HIGHLIGHT THIS.

.LONG TERM...SUNDAY THOUGH THURSDAY MORNING.

HIGH PRESSURE OVER THE WESTERN US WILL DOMINATE THIS PERIOD WITH HOT
TEMPERATURES UNTIL MONDAY WHEN THE RIDGE BEGINS TO FLATTEN A BIT AS
AN UPPER LEVEL TROUGH APPROACHES THE PACIFIC NORTHWEST...HELPING TO
TAMPER TEMPS A FEW DEGREES AND INCREASE WINDS ACROSS THE AREA. THE
TROUGH WILL PASS BY WELL TO THE NORTH KEEPING CHANCES OF PRECIP WELL
NORTH...WITH ONLY SLIGHTLY COOLER TEMPS...NEAR NORMAL FOR THIS TIME
OF YEAR...AND SOME HIGH CLOUDS EXPECTED FOR THE AREA FOR TUESDAY AND
WEDNESDAY. BY THURSDAY ANOTHER TROUGH IS PROGGED TO DROP DOWN THE
BACK SIDE OF THE DEPARTING TROUGH FROM WEDNESDAY. THE GFS AND ECMWF
HANDLE THIS TROUGH DIFFERENTLY...WITH THE ECMWF BEING THE SLOWER OF
THE TWO AND DIGGING IT ALONG THE COAST IN CONTRAST TO THE GFS WHICH
IS MORE PROGRESSIVE AND FURTHER INLAND. BOTH MODELS KEEP DYNAMICS

.SYNOPSIS...MOTORISTS MAY ENCOUNTER SOME PATCHES OF FOG THIS

THERE WILL BE THE POSSIBILITY OF A THUNDERSTORM OR TWO EACH DAY.

&&

.SHORT TERM...TODAY THROUGH FRIDAY. SOME PATCHY FOG MAY DEVELOP
THIS MORNING AS THINGS SETTLE DOWN A BIT. HOWEVER THERE ARE
STILL A FEW REMNANT SHOWERS ACROSS NORTHERN NEVADA THIS MORNING
AS WELL AS SOME THUNDERSTORM ACTIVITY OVER ELKO COUNTY. THE MODELS
SEEM TO BE IN VERY GOOD AGREEMENT WITH THE PROJECTED MOVEMENT EAST
OF A TROUGH OF LOW PRESSURE AND AN INCOMING RIDGE PATTERN.

TODAY THROUGH THIS EVENING. AS THE TROUGH SLOWLY EXITS...ONE MORE
SHORT WAVE LOBE WILL INSTIGATE SOME CONVECTION OVER EASTERN NEVADA
THIS AFTERNOON JUST AS A SHORT WAVE RIDGE AXIS BEGINS TO MOVE
INTO COASTAL CALIFORNIA. THE RIDGE IS EXPECTED TO AMPLIFY QUICKLY
LATE AFTERNOON AND EARLY EVENING AND SPREAD ITS INFLUENCE EASTWARD
THUS CONVECTION SHOULD SHUT OFF RATHER ABRUPTLY LATE THIS AFTERNOON
OR VERY EARLY THIS EVENING. WESTERN NEVADA WILL BEGIN TO WARM
SUBSTANTIALLY DUE TO THE SOUTHERLY PUSH OF DRIER AIR.

MIDNIGHT TONIGHT THROUGH FRIDAY. THE UPPER LEVEL PATTERN REMAINS
PROGRESSIVE. ALTHOUGH THE RIDGE WILL MOVE OVER THE STATE
FRIDAY TO BRING WARMER CONDITIONS...IT WILL ALSO UNDERGO DE-
AMPLIFICATION...SO DRYING WILL BE LIMITED. THERE WILL BE ENOUGH
MOISTURE UNDER THE RIDGE TO ALLOW FOR SOME THUNDERSTORM
DEVELOPMENT AGAIN FRIDAY AFTERNOON OVER EASTERN NEVADA AS WELL AS
ALONG THE HIGHWAY 50 CORRIDOR IN CENTRAL NEVADA.

.LONG TERM...FRIDAY NIGHT THROUGH THURSDAY. THE MODELS ARE IN FAIRLY
GOOD AGREEMENT THROUGH THE SUN-MON TIME FRAME.

RIDGE BUILDS IN FRIDAY AND SATURDAY WITH WARMING AND "DRYING"
CONDITIONS. RESIDUAL MOISTURE WILL ALLOW FOR SOME AFTERNOON BUILDUPS
IN CENTRAL AND NORTHEASTERN NEVADA. PERHAPS EVEN AN ISOLATED
SHOWER/STORM. NOT MUCH IN THE WAY OF PRECIP EXPECTED.

SUNDAY AND MONDAY...BROAD SW FLOW SPREADS ACROSS THE AREA. RH WILL
DROP AND WINDS WILL INCREASE. A FEW AFTERNOON SHOWERS/STORMS WILL BE
POSSIBLE ACROSS NORTHERN NEVADA...BUT AGAIN..NOT EXPECTING ANY REAL
PRECIP. THIS WILL BE THE WARMEST WEEKEND YET. MANY PLACES WILL BE IN
THE 80S...WITH SOME VALLEY LOCATIONS BELOW 5000FT AROUND 90.

HEADING INTO THE MIDDLE PART OF NEXT WEEK...A TROUGH WILL SLOWLY
WOBBLE ACROSS NORTHERN NEVADA. THIS WILL PROVIDE THE BEST CHANCE IN
THE LONG TERM FOR BENEFICIAL AMOUNTS OF RAIN. THE LATEST SUITE OF
MODEL RUNS SHOW A MORE NORTHERN TRACK WITH THE UPPER LEVEL STORM
SYSTEM. DECIDED TO TWEAK POPS DOWN JUST A BIT...BUT DUE TO
UNCERTAINTY...DID NOT WANT TO MAKE ANY SIGNIFICANT CHANGES. STILL
KEPT ISOLATED SHOWERS/STORMS FOR NORTHERN NEVADA. GIVEN THE CURRENT
MODEL TRENDS...WOULD NOT BE SHOCKED TO SEE THIS CONTINUE TO SHIFT

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
1051 PM PDT WED MAY 27 2015

.UPDATE...
MINOR UPDATE TO CLEAN UP THE ZONE FORECAST WORDING.

A MINOR UPPER DISTURBANCE MOVING ACROSS NORTHERN NEVADA IS
PRODUCING A MID LEVEL CLOUD DECK OVER PERSHING AND EASTERN
CHURCHILL COUNTIES. THERE ARE ALSO VERY ISOLATED SHOWERS AND EVEN
A THUNDERSTORM OVER NORTHEAST PERSHING AND SOUTHEAST HUMBOLDT
COUNTIES, WITH LIGHTNING DETECTION INDICATING SOME IN-CLOUD
LIGHTNING NEAR THE BORDER OF THE TWO COUNTIES. THE WAVE WILL MOVE
AWAY FROM THE REGION IN THE NEXT COUPLE HOURS BRINGING THE END TO
THE ISOLATED CONVECTIVE THREAT OVER NORTHEAST PERSHING COUNTY.
SNYDER

&&

.SYNOPSIS...
HIGH PRESSURE WILL BRING WARMING TEMPERATURES FOR THE NEXT FEW
DAYS, WITH TEMPERATURES TOPPING OUT WELL ABOVE AVERAGE FOR THE
WEEKEND. A TROUGH WILL BRING BREEZY CONDITIONS SUNDAY AND MONDAY
WITH MUCH COOLER TEMPERATURES BY MONDAY. THERE IS A LOW CHANCE OF
THUNDERSTORMS SUNDAY AND MONDAY, MAINLY NORTH OF INTERSTATE 80.

&&

.PREVIOUS DISCUSSION... /ISSUED 254 PM PDT WED MAY 27 2015/

SHORT TERM...

LOW PRESSURE CONTINUES TO PUSH EAST OF OUR AREA WITH DRIER AIR AND
SUBSIDENCE STARTING TO TAKE HOLD ACROSS OUR FORECAST AREA. THERE ARE
A FEW AREAS OF WEAK INSTABILITY STILL THIS AFTERNOON, MAINLY SOUTH
OF HAWTHORNE AND NORTH OF SUSANVILLE, WHERE A FEW ISOLATED SHOWERS
AND THUNDERSTORMS ARE POSSIBLE. FOR TOMORROW, AGAIN CHANCES ARE SLIM
FOR ANY CONVECTIVE DEVELOPMENT, BUT THERE REMAINS A VERY SLIGHT
CHANCE OF SHOWERS EAST OF SUSANVILLE AND ALONG THE SIERRA CREST
SOUTH OF BRIDGEPORT. WARM AIR ALOFT WILL STRENGTHEN THE CAP, KEEPING
ANY STORMS VERY ISOLATED AT BEST.

AS WE GO INTO THURSDAY AND FRIDAY, WE WILL SEE A WARMING TREND AS
HIGH PRESSURE STRENGTHENS OVER THE WEST COAST. BY SATURDAY, WE
EXPECT THE WARMEST TEMPERATURES OF THE YEAR SO FAR. TEMPERATURES IN
WESTERN NEVADA WILL BE NEAR 90 DEGREES WITH UPPER 70S AND LOW 80S IN
THE SIERRA.

AS HOT TEMPERATURES RETURN TO THE REGION AND FOLKS BEGIN THINKING
ABOUT SUMMER, PEOPLE MAY THINK ITS A GOOD IDEA TO COOL OFF IN LOCAL
LAKES AND RIVERS. UNFORTUNATELY, THE CURRENT WATER TEMPERATURE IN
LAKE TAHOE IS ABOUT 53 DEGREES. PLEASE BE AWARE OF THE COLD WATER
TEMPERATURES THIS TIME OF YEAR IN LOCAL LAKES AND RIVERS.
HYPOTHERMIA IS A REAL THREAT DURING EARLY SUMMER, ESPECIALLY IF YOU
AREN`T EXPECTING IT. HOON

LONG TERM...SUNDAY THROUGH WEDNESDAY...

UPPER LEVEL RIDGE BEGINS TO SHIFT EASTWARD SUNDAY AS AN AREA OF LOW
PRESSURE APPROACHES THE NORTHWEST COAST. THIS WILL SEND A COLD FRONT
THROUGH NORTHERN CA/NV WITH BREEZY WINDS SUNDAY AND MONDAY
AFTERNOONS. THE NEGATIVELY TILED UPPER LEVEL TROUGH WILL SHIFT INTO
THE SIERRA AND NORTHWEST NEVADA MONDAY, WHICH IS FAVORABLE FOR
INCREASED THUNDERSTORM DYNAMICS. HOWEVER, THE DEEPEST MOISTURE
REMAINS NORTH INTO OREGON, SO HAVE ONLY LOW END CHANCES FOR SHOWERS
AND THUNDERSTORMS FOR AREAS MAINLY NORTH OF SUSANVILLE-FALLON LINE.
A FEW SHORTWAVES MOVE THROUGH THE FLOW, KEEPING SLIGHT CHANCES FOR
SHOWERS NORTH OF INTERSTATE 80 THROUGH TUESDAY. AFTER ANOTHER WARM
DAY ON SUNDAY, HIGH TEMPERATURES WILL DROP TO NEAR NORMAL FOR THE
EARLY PART OF NEXT WEEK AS THE UPPER TROUGH LINGERS OVER THE REGION.
LONG RANGE MODELS ARE SHOWING RIDGING BUILDING BACK INTO THE WEST
WEDNESDAY INTO THURSDAY OF NEXT WEEK WHICH WILL LEAD TO DRIER AND
WARMER CONDITIONS. DJ

AVIATION...

CUMULUS DEVELOPMENT ACROSS THE NORTHERN SIERRA AND NORTHWEST NEVADA
HAS BEEN FAIRLY FLAT TODAY. THE ONLY PLACES WHERE ISOLATED
THUNDERSTORMS APPEAR TO BE A POSSIBILITY THIS AFTERNOON ARE ACROSS
SOUTHERN MONO AND MINERAL COUNTIES. OTHERWISE, SCATTERED STORMS HAVE
FORMED THROUGH CENTRAL AND EASTERN NV. STORMS WILL DISSIPATE AROUND
SUNSET TONIGHT.

FOG WILL LIKELY REDEVELOP TONIGHT THROUGH THE MARTIS VALLEY,
INCLUDING KTRK, FROM AROUND 10Z-14Z. OTHERWISE, VFR CONDITIONS ARE
EXPECTED ACROSS THE REGION AS A RIDGE OF HIGH PRESSURE BUILDS INTO
THE WEST. DJ

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
1051 PM PDT WED MAY 27 2015

.UPDATE...
MINOR UPDATE TO CLEAN UP THE ZONE FORECAST WORDING.

A MINOR UPPER DISTURBANCE MOVING ACROSS NORTHERN NEVADA IS
PRODUCING A MID LEVEL CLOUD DECK OVER PERSHING AND EASTERN
CHURCHILL COUNTIES. THERE ARE ALSO VERY ISOLATED SHOWERS AND EVEN
A THUNDERSTORM OVER NORTHEAST PERSHING AND SOUTHEAST HUMBOLDT
COUNTIES, WITH LIGHTNING DETECTION INDICATING SOME IN-CLOUD
LIGHTNING NEAR THE BORDER OF THE TWO COUNTIES. THE WAVE WILL MOVE
AWAY FROM THE REGION IN THE NEXT COUPLE HOURS BRINGING THE END TO
THE ISOLATED CONVECTIVE THREAT OVER NORTHEAST PERSHING COUNTY.
SNYDER

&&

.SYNOPSIS...
HIGH PRESSURE WILL BRING WARMING TEMPERATURES FOR THE NEXT FEW
DAYS, WITH TEMPERATURES TOPPING OUT WELL ABOVE AVERAGE FOR THE
WEEKEND. A TROUGH WILL BRING BREEZY CONDITIONS SUNDAY AND MONDAY
WITH MUCH COOLER TEMPERATURES BY MONDAY. THERE IS A LOW CHANCE OF
THUNDERSTORMS SUNDAY AND MONDAY, MAINLY NORTH OF INTERSTATE 80.

.PREVIOUS DISCUSSION... /ISSUED 254 PM PDT WED MAY 27 2015/

SHORT TERM...

LOW PRESSURE CONTINUES TO PUSH EAST OF OUR AREA WITH DRIER AIR AND
SUBSIDENCE STARTING TO TAKE HOLD ACROSS OUR FORECAST AREA. THERE ARE
A FEW AREAS OF WEAK INSTABILITY STILL THIS AFTERNOON, MAINLY SOUTH
OF HAWTHORNE AND NORTH OF SUSANVILLE, WHERE A FEW ISOLATED SHOWERS
AND THUNDERSTORMS ARE POSSIBLE. FOR TOMORROW, AGAIN CHANCES ARE SLIM
FOR ANY CONVECTIVE DEVELOPMENT, BUT THERE REMAINS A VERY SLIGHT
CHANCE OF SHOWERS EAST OF SUSANVILLE AND ALONG THE SIERRA CREST
SOUTH OF BRIDGEPORT. WARM AIR ALOFT WILL STRENGTHEN THE CAP, KEEPING
ANY STORMS VERY ISOLATED AT BEST.

AS WE GO INTO THURSDAY AND FRIDAY, WE WILL SEE A WARMING TREND AS
HIGH PRESSURE STRENGTHENS OVER THE WEST COAST. BY SATURDAY, WE
EXPECT THE WARMEST TEMPERATURES OF THE YEAR SO FAR. TEMPERATURES IN
WESTERN NEVADA WILL BE NEAR 90 DEGREES WITH UPPER 70S AND LOW 80S IN
THE SIERRA.

AS HOT TEMPERATURES RETURN TO THE REGION AND FOLKS BEGIN THINKING
ABOUT SUMMER, PEOPLE MAY THINK ITS A GOOD IDEA TO COOL OFF IN LOCAL
LAKES AND RIVERS. UNFORTUNATELY, THE CURRENT WATER TEMPERATURE IN
LAKE TAHOE IS ABOUT 53 DEGREES. PLEASE BE AWARE OF THE COLD WATER
TEMPERATURES THIS TIME OF YEAR IN LOCAL LAKES AND RIVERS.
HYPOTHERMIA IS A REAL THREAT DURING EARLY SUMMER, ESPECIALLY IF YOU
AREN`T EXPECTING IT. HOON

LONG TERM...SUNDAY THROUGH WEDNESDAY...

UPPER LEVEL RIDGE BEGINS TO SHIFT EASTWARD SUNDAY AS AN AREA OF LOW
PRESSURE APPROACHES THE NORTHWEST COAST. THIS WILL SEND A COLD FRONT
THROUGH NORTHERN CA/NV WITH BREEZY WINDS SUNDAY AND MONDAY
AFTERNOONS. THE NEGATIVELY TILED UPPER LEVEL TROUGH WILL SHIFT INTO
THE SIERRA AND NORTHWEST NEVADA MONDAY, WHICH IS FAVORABLE FOR
INCREASED THUNDERSTORM DYNAMICS. HOWEVER, THE DEEPEST MOISTURE
REMAINS NORTH INTO OREGON, SO HAVE ONLY LOW END CHANCES FOR SHOWERS
AND THUNDERSTORMS FOR AREAS MAINLY NORTH OF SUSANVILLE-FALLON LINE.
A FEW SHORTWAVES MOVE THROUGH THE FLOW, KEEPING SLIGHT CHANCES FOR
SHOWERS NORTH OF INTERSTATE 80 THROUGH TUESDAY. AFTER ANOTHER WARM
DAY ON SUNDAY, HIGH TEMPERATURES WILL DROP TO NEAR NORMAL FOR THE
EARLY PART OF NEXT WEEK AS THE UPPER TROUGH LINGERS OVER THE REGION.
LONG RANGE MODELS ARE SHOWING RIDGING BUILDING BACK INTO THE WEST
WEDNESDAY INTO THURSDAY OF NEXT WEEK WHICH WILL LEAD TO DRIER AND
WARMER CONDITIONS. DJ

AVIATION...

CUMULUS DEVELOPMENT ACROSS THE NORTHERN SIERRA AND NORTHWEST NEVADA
HAS BEEN FAIRLY FLAT TODAY. THE ONLY PLACES WHERE ISOLATED
THUNDERSTORMS APPEAR TO BE A POSSIBILITY THIS AFTERNOON ARE ACROSS
SOUTHERN MONO AND MINERAL COUNTIES. OTHERWISE, SCATTERED STORMS HAVE
FORMED THROUGH CENTRAL AND EASTERN NV. STORMS WILL DISSIPATE AROUND
SUNSET TONIGHT.

FOG WILL LIKELY REDEVELOP TONIGHT THROUGH THE MARTIS VALLEY,
INCLUDING KTRK, FROM AROUND 10Z-14Z. OTHERWISE, VFR CONDITIONS ARE
EXPECTED ACROSS THE REGION AS A RIDGE OF HIGH PRESSURE BUILDS INTO
THE WEST. DJ

.REV WATCHES/WARNINGS/ADVISORIES...
