AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
736 PM PDT TUE MAY 26 2015

.SYNOPSIS...AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS CAN BE
EXPECTED THROUGH THURSDAY ACROSS THE SOUTHERN GREAT BASIN MAINLY
OVER THE HIGHER ELEVATIONS. OTHERWISE EXPECT DRY CONDITIONS WITH A
WARMING TREND THROUGH THE END OF THE WEEK. THE WARMEST WEATHER OF
THE YEAR SO FAR IS EXPECTED THIS WEEKEND.
&&

.UPDATE...A TON OF CIRRUS HAS WORKED IN ACROSS THE SOUTHERN HALF OF
THE AREA AS THE JET STREAM PASSES BY OVERHEAD ACCOMPANIED BY A NICE
AMOUNT OF HIGH LEVEL MOISTURE. THE CIRRUS WAS ENHANCING OFF THE SAN
BERNARDINO RANGE ESPECIALLY INTO THE MORONGO BASIN AND TO AREAS JUST
EAST OF BARSTOW. AS A RESULT, I ADJUSTED UP SKY COVER FOR TONIGHT
AND WEDNESDAY MORNING ACROSS THE SOUTHERN HALF OF THE AREA
ESPECIALLY SOUTH OF INTERSTATE 40. AREAS IN MOHAVE COUNTY MAY BE A
BIT UNDERDONE STILL TOMORROW MORNING WITH SKY COVER BUT THIS CAN BE
ADJUSTED LATER ON.

RADAR SHOWED A FEW SHOWERS STILL ACROSS LINCOLN COUNTY MOVING EAST
AND A FEW SHOWERS AND THUNDERSTORMS IN ESMERALDA AND NORTHERN INYO
COUNTIES. ACTIVITY IN GENERAL HAS NOT BEEN AS EXTENSIVE AS YESTERDAY
EVENING AND THUS WITH THE LOSS OF HEATING SHOULD DIMINISH EARLIER
THAN WHAT WE SAW LAST NIGHT.

OTHERWISE THE FORECAST LOOKS IN GOOD SHAPE.
&&

.AVIATION...FOR MCCARRAN...GUSTY SOUTHWEST WINDS WILL CONTINUE
THROUGH AROUND 06Z TUESDAY OR SO THEN DECREASE TO AROUND 8-10 KTS.
ONCEA AGAIN ON TUESDAY EAST TO SOUTHEAST WINDS AT 4-8 KTS SHOULD
BECOME MORE SOUTHERLY BETWEEN 22Z TUESDAY AND 00Z WEDNESDAY AND
INCREASE TO 10-14 KTS WITH GUSTS TO 22 KTS. SCT-BKN CLOUDS MAINALY
AOA 25K FEET WITH A FEW BASES AS LOW AS 12K FEET.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...MAINLY DIURNAL WIND DIRECTIONS THROUGH TONIGHT AT 15
KTS OR LESS. SCT-BKN CLOUDS AOA 25K FEET TONIGHT SOUTH OF KIYK-KDRA-
KSGU LINE. NORTH OF THIS LINE THERE WILL SHRA/TSRA THROUGH ABOUT 06Z
TUESDAY OR SO. GUSTY AND ERRATIC WINDS...MVFR OR LOWER VSBY IN
HEAVIER SHRA AND CIGS TO 5K-8K FEET ARE POSSIBLE. LOCAL MOUNTAIN
OBSCURATIONS ARE ALSO POSSIBLE. SIMILAR CONDITIONS ARE EXPECTED
TUESDAY.
&&

.PREVIOUS DISCUSSION...
ISSUED AT 326 PM PDT TUE MAY 26 2015

.SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT.

A BROAD TROUGH OF LOW PRESSURE REMAINS ACROSS THE WESTERN U.S.
DURING THE SHORT TERM. ANOTHER SHORTWAVE WILL SKIRT THE AREA
TOMORROW BRINGING ADDITIONAL SHOWERS AND THUNDERSTORMS TO THE
SOUTHERN GREAT BASIN DURING THE AFTERNOON HOURS. THE MAIN TROUGH
WILL WEAKEN AND BEGIN TO EJECT EASTWARD ON THURSDAY ALLOWING FOR
MORE ZONAL FLOW TO DEVELOP OVER THE DESERT SOUTHWEST. THIS WILL
BRING A WARMING TREND WITH HIGH TEMPERATURES CREEPING BACK ABOVE
NORMAL BY THURSDAY.


.LONG TERM...FRIDAY THROUGH TUESDAY.

THE STORY OF THE LONG TERM PERIOD WILL BE AFTERNOON HIGHS PUSHING
THE CENTURY MARK ACROSS MOST DESERT LOCALES THROUGH THE BEGINNING OF
NEXT WEEK...AS A SHORTWAVE RIDGE TRAVERSES OVER THE AREA THIS
WEEKEND. MINOR DIFFERENCES CONTINUE TO EXIST WITH OPERATIONAL
GUIDANCE REGARDING THE OVERALL AMPLITUDE OF THE AFOREMENTIONED
RIDGE. HOWEVER ALL BASE AND DERIVED GUIDANCE CONTINUES TO
CONSISTENTLY INDICATE HIGH TEMPERATURES AT LEAST WITHIN A FEW
DEGREES OF EACH OTHER FROM MODEL TO MODEL OVER THE WEEKEND...FURTHER
INCREASING CONFIDENCE OF THE FIRST 100 DEGREE DAY OF 2015 FOR MANY
DESERT LOCALES...INCLUDING LAS VEGAS. BOTH THE OPERATIONAL GFS/ECMWF
INDICATE A FAIRLY VIGOROUS TROUGH IMPINGING ON THE GREAT BASIN LATE
SUNDAY INTO MONDAY...WHICH WILL INCREASE SOUTHERLY/SOUTHWESTERLY
FLOW ACROSS MUCH OF THE CWA IN THIS TIMEFRAME. THIS WILL PROMOTE
GOOD MIXING...ESPECIALLY ON SUNDAY AFTERNOON...WHICH WILL BUMP UP
HIGH TEMPERATURES A FEW DEGREES FROM FRIDAY AND SATURDAY LIKELY
MAKING THIS THE HOTTEST DAY OF THE YEAR THUS FAR. TEMPERATURES WILL
COOL A FEW DEGREES MONDAY AND TUESDAY IN RESPONSE TO THE PASSING
TROUGH...BUT WILL REMAIN ABOVE SEASONAL NORMALS.

TOMORROW BRINGING ADDITIONAL SHOWERS AND THUNDERSTORMS TO THE
SOUTHERN GREAT BASIN DURING THE AFTERNOON HOURS. THE MAIN TROUGH
WILL WEAKEN AND BEGIN TO EJECT EASTWARD ON THURSDAY ALLOWING FOR
MORE ZONAL FLOW TO DEVELOP OVER THE DESERT SOUTHWEST. THIS WILL
BRING A WARMING TREND WITH HIGH TEMPERATURES CREEPING BACK ABOVE
NORMAL BY THURSDAY.


.LONG TERM...FRIDAY THROUGH TUESDAY.

THE STORY OF THE LONG TERM PERIOD WILL BE AFTERNOON HIGHS PUSHING
THE CENTURY MARK ACROSS MOST DESERT LOCALES THROUGH THE BEGINNING OF
NEXT WEEK...AS A SHORTWAVE RIDGE TRAVERSES OVER THE AREA THIS
WEEKEND. MINOR DIFFERENCES CONTINUE TO EXIST WITH OPERATIONAL
GUIDANCE REGARDING THE OVERALL AMPLITUDE OF THE AFOREMENTIONED
RIDGE. HOWEVER ALL BASE AND DERIVED GUIDANCE CONTINUES TO
CONSISTENTLY INDICATE HIGH TEMPERATURES AT LEAST WITHIN A FEW
DEGREES OF EACH OTHER FROM MODEL TO MODEL OVER THE WEEKEND...FURTHER
INCREASING CONFIDENCE OF THE FIRST 100 DEGREE DAY OF 2015 FOR MANY
DESERT LOCALES...INCLUDING LAS VEGAS. BOTH THE OPERATIONAL GFS/ECMWF
INDICATE A FAIRLY VIGOROUS TROUGH IMPINGING ON THE GREAT BASIN LATE
SUNDAY INTO MONDAY...WHICH WILL INCREASE SOUTHERLY/SOUTHWESTERLY
FLOW ACROSS MUCH OF THE CWA IN THIS TIMEFRAME. THIS WILL PROMOTE
GOOD MIXING...ESPECIALLY ON SUNDAY AFTERNOON...WHICH WILL BUMP UP
HIGH TEMPERATURES A FEW DEGREES FROM FRIDAY AND SATURDAY LIKELY
MAKING THIS THE HOTTEST DAY OF THE YEAR THUS FAR. TEMPERATURES WILL
COOL A FEW DEGREES MONDAY AND TUESDAY IN RESPONSE TO THE PASSING
TROUGH...BUT WILL REMAIN ABOVE SEASONAL NORMALS.




.AVIATION...FOR MCCARRAN...VFR CONDITIONS. SOUTHEAST TO SOUTH WINDS
OF 8-12 KTS WITH GUSTS F 15-20 KTS ARE EXPECTED THROUGH 00Z WHEN
WINDS SHOULD TREND TOWARD THE SOUTHWEST. WIND SPEEDS SHOULD BEGIN
TO DECREASE AFTER SUNSET. SIMILAR CONDITIONS ARE EXPECTED WEDNESDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...MAINLY DIURNAL WIND DIRECTIONS THROUGH TONIGHT AT 15
KTS OR LESS. SCT-BKN CLOUDS AOA 25K FEET TONIGHT SOUTH OF KIYK-
KDRA-KSGU LINE. NORTH OF THIS LINE THERE WILL SHRA/TSRA THROUGH
ABOUT 06Z OR SO WEDNESDAY. GUSTY AND ERRATIC WINDS...MVFR OR LOWER
VSBY IN HEAVIER SHRA AND CIGS TO 5K-8K FEET ARE POSSIBLE. LOCAL

912 AM PDT MON MAY 25 2015

.SYNOPSIS...A TROUGH ALOFT COMBINED WITH ENOUGH MOISTURE AND
INSTABILITY WILL HELP TO SPARK OFF MAINLY AFTERNOON AND EVENING
SHOWERS AND THUNDERSTORMS TODAY THROUGH THURSDAY ACROSS THE SOUTHERN
GREAT BASIN ESPECIALLY OVER THE HIGHER ELEVATIONS. OTHERWISE EXPECT
DRY CONDITIONS WITH A WARMING TREND THROUGH THE END OF THE WEEK. THE
WARMEST WEATHER OF THE YEAR SO FAR IS EXPECTED THIS WEEKEND.
&&

.UPDATE...MADE SOME MINOR MODIFICATIONS TO POP/SKY/WX/WIND THROUGH
THIS EVENING. THE SHOWERS THAT PERSISTED OVERNIGHT ACROSS THE
SOUTHERN GREAT BASIN ARE TAPERING OFF QUICKLY THIS MORNING. MODEST
INSTABILITY IS EXPECTED TO DEVELOP ONCE AGAIN THIS AFTERNOON ACROSS
THE SIERRA AND SOUTHERN GREAT BASIN AND WILL LIKELY LEAD TO ANOTHER
ROUND OF SHOWERS/ISOLATED THUNDERSTORMS TRIGGERED BY A SHORTWAVE
MOVING ACROSS CENTRAL NEVADA. I DID ADD IN A SLIGHT CHANCE OF PRECIP
OVER THE SPRING/SHEEP RANGES IN CLARK COUNTY AS MODELS DO HINT AT
THE POTENTIAL FOR SHOWERS THERE. ALSO TWEAKED WINDS TO BETTER MATCH
THE HRRR..SPECIFICALLY IN INCREASING SPEEDS AND KEEPING SOUTHEAST
WINDS GOING AT KLAS FOR A BIT LONGER.
&&

.AVIATION...FOR MCCARRAN...VFR CONDITIONS. SOUTHEAST WINDS ARE
EXPECTED TO INCREASE TO 8-14 KTS WITH GUSTS 15-20 KTS EARLY THIS
AFTERNOON. MODELS NOW INDICATED THAT A TURN TO SOUTH/SOUTHWEST WINDS
WILL BE A BIT LATER THAT PREVIOUSLY INDICATED. FOR THE MOMENT THE
BEST ESTIMATE AT THIS SWITCH IS 23-00Z THIS AFTERNOON. SPEEDS SHOULD
BEGIN TO DECREASE AFTER SUNSET. SIMILAR CONDITIONS ARE EXPECTED
WEDNESDAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...MAINLY DIURNAL WIND DIRECTIONS THROUGH TONIGHT AT 15
KTS OR LESS. A FEW CLOUDS AOA 12K FEET TODAY WITH SCT-BKN CLOUDS AOA
25K FEET TONIGHT SOUTH OF KIYK-KDRA-KSGU LINE. NORTH OF THIS LINE
THERE WILL BE A POSSIBILITY OF SHRA/TSRA AROUND AGAIN MAINLY AFTER
20Z TODAY THROUGH 06Z OR SO WEDNESDAY. GUSTY AND ERRATIC

303 AM PDT MON MAY 25 2015

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT.

THE CONVECTIVE COMPLEX THAT GOT GOING YESTERDAY EVENING ACROSS SOUTH-
CENTRAL NEVADA HAS PUSHED TOWARD THE UTAH BORDER EARLY THIS MORNING
IN A SOMEWHAT DECAYED STATE. MOST OF THE MAIN COMPLEX WAS NOW JUST
AN AREA OF LIGHT TO MODERATE RAIN, HOWEVER, WE HAVE SEEN SOME CELLS
DEVELOP ON THE SOUTHERN FLANK OF THE MAIN AREA OF PRECIPITATION
ACROSS NORTHERN MOHAVE COUNTY IN THE LAST HOUR. BASED ON THE HRRR,
THIS ACTIVITY IS ALL SLATED TO MOVE EAST AND SHOULD EXIT THE AREA BY
LATER THIS MORNING. HOWEVER, A SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS WAS LEFT IN THE FORECAST FOR LINCOLN COUNTY AND ADDED
TO THE FORECAST FOR NORTHERN MOHAVE COUNTY TO ACCOUNT FOR THIS.
WHATEVER CLOUDS ARE AROUND FROM THIS SHOULD CLEAR OUT AS WELL BY
LATER THIS MORNING.

WE REMAIN IN A BROAD TROUGH IN THE MID AND UPPER LEVELS OF THE
ATMOSPHERE ACROSS THE SOUTHWEST. TWO FEATURES ARE OF NOTE THIS
MORNING. ONE IS THE MAIN JET STREAM WHICH IS PASSING BY TO OUR
SOUTH. THIS WILL PUSH A BAND OF HIGHER LEVEL MOISTURE ACROSS THE
SOUTHERN THIRD OF THE AREA TODAY INTO TONIGHT RESULTING IN HIGH
CLOUDS. SOME OF THE CLOUDS COULD ENHANCE OFF THE COASTAL RANGES OF
SOCAL BY LATER TODAY INTO TONIGHT AND THUS SKY COVER HERE MAY BE
UNDERDONE. THE SECOND FEATURE TO WATCH CAN BE SEEN ON WATER VAPOR
IMAGERY DIGGING SOUTH ACROSS NORCAL AND NORTHWESTERN NEVADA THIS
MORNING. THIS NEXT PIECE OF ENERGY WILL WORK SOUTH AND EAST ACROSS
THE SOUTHERN HALF OF NEVADA TODAY AND ONCE AGAIN WITH THE MOISTURE
(MAINLY MID-LEVEL) AND INSTABILITY IN PLACE HELP TO SPARK OFF
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS THIS AFTERNOON ACROSS THE
SOUTHERN GREAT BASIN ESPECIALLY OVER THE HIGHER ELEVATIONS. SIMILAR
TO YESTERDAY, ACTIVITY SHOULD PUSH WEST TO EAST ACROSS THE AREA.
INSPECTING THE HRRR AND LOCAL 4KM HIGH RESOLUTION ARW AND NMM
MODELS, THERE APPEARS TO BE TWO MAIN AREAS THAT WILL NEED TO BE
WATCHED THIS AFTERNOON. THE FIRST IS NORTHERN LINCOLN COUNTY AND THE
SECOND WILL BE ACROSS ESMERALDA COUNTY AS WELL AS THE WHITE
MOUNTAINS, NORTHERN OWENS VALLEY AND EASTERN SLOPES OF THE SOUTHERN
SIERRA NEVADA. POPS WERE RAISED SLIGHTLY FOR THE LATTER. THE MAIN
THREATS IN AND NEAR THUNDERSTORMS TODAY WILL BE GUSTY AND ERRATIC
WINDS TO 45 MPH, SMALL HAIL, LIGHTNING AND DOWNPOURS THAT COULD
PRODUCE LOCALIZED FLOODING. SHOWERS AND THUNDERSTORMS SHOULD
DECREASE THIS EVENING WITH THE LOSS OF HEATING. DESPITE THE TROUGH
OVERHEAD TEMPS WILL BE ON THE RISE TODAY WITH HIGHS RETURNING BACK
CLOSER TO NORMAL. THIS WILL SNAP THE SUB-90 STREAK IN LAS VEGAS THAT
HAS BEEN AROUND SINCE MAY 4TH. WITH TEMPS RISING, SNOW LEVELS WILL
BE AROUND 11000 FEET TODAY BUT ANY HEAVIER SHOWERS OVER THE HIGHEST
MOUNTAINS COULD AGAIN DROP A FEW INCHES OF SNOW. HIKERS AND OUTDOOR
ENTHUSIASTS IN THE SOUTHERN SIERRA NEVADA AND WHITE MOUNTAINS SHOULD
AGAIN BE ALERT FOR POTENTIAL WINTRY CONDITIONS ON AREA TRAILS AND
CAMPGROUNDS HIGHER UP.

A MID/UPPER LEVEL LOW WILL PUSH EAST ACROSS BAJA CALIFORNIA TONIGHT
AND HELP TO PUSH ANY CIRRUS ACROSS THE SOUTHERN HALF OF OUR AREA OFF
TO THE EAST ON WEDNESDAY, HOWEVER, SOME THICKER HIGH LEVEL CLOUDS
MAY START THE DAY OFF IN MOHAVE COUNTY. A BROAD MID/UPPER LEVEL
TROUGH WILL REMAIN ACROSS THE AREA FOR WEDNESDAY AND WITH ENERGY
RIPPLING THROUGH THE BASE OF THE TROUGH AND ENOUGH MOISTURE AS WELL
AS INSTABILITY REMAINING IN PLACE ONCE AGAIN RESULT IN SHOWERS AND
THUNDERSTORMS POPPING UP WITH THE HEATING OF THE DAY ACROSS THE
SOUTHERN GREAT BASIN. ONCE AGAIN EXPECT MAINLY AFTERNOON AND EVENING
ACTIVITY MAINLY OVER THE HIGHER ELEVATIONS. TEMPS WILL RISE A FEW
MORE DEGREES AS THE ATMOSPHERE CONTINUES TO WARM FURTHER. THIS
SHOULD PUSH HIGHS BACK CLOSER TO NORMAL AND I SIDED WITH THE WARMER
MAV (GFS) NUMBERS FOR HIGHS.

THE PESKY TROUGH ALOFT WILL FINALLY ALLOW FOR A FULL-FLEDGED FEEL OF
SPRING (MORE LIKE SUMMER DEPENDING ON YOUR TASTE AND HOW THIS SPRING
HAS BEEN) BY THURSDAY AS A RIDGE ALOFT STARTS TO TRANSITION IN. IF
YOU HAVE BEEN HOLDING OFF USING ON THE AIR CONDITIONER MUCH, GET
READY TO CRANK IT AS HIGHS SOAR TO ABOVE NORMAL READINGS FOR A
CHANGE. A WEAK RIPPLE IN THE FLOW AND LINGERING MOISTURE AND
INSTABILITY COULD STILL SET OFF A FEW SHOWERS AND THUNDERSTORMS IN
THE AFTERNOON AND EVENING OVER THE SOUTHERN GREAT BASIN, HOWEVER,
ACTIVITY SHOULD BE LESS IN AREAL COVERAGE COMPARED TO TUESDAY AND
WEDNESDAY. ONCE AGAIN ANY SHOWERS AND THUNDERSTORMS SHOULD END IN
THE EVENING WITH THE LOSS OF HEATING.

.LONG TERM...FRIDAY THROUGH TUESDAY.

THE STORY OF THE LONG TERM PERIOD WILL BE AFTERNOON HIGHS PUSHING
THE CENTURY MARK ACROSS MOST DESERT LOCALES THROUGH THE BEGINNING OF

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
303 AM PDT MON MAY 25 2015

.SYNOPSIS...A TROUGH ALOFT COMBINED WITH ENOUGH MOISTURE AND
INSTABILITY WILL HELP TO SPARK OFF MAINLY AFTERNOON AND EVENING
SHOWERS AND THUNDERSTORMS TODAY THROUGH THURSDAY ACROSS THE SOUTHERN
GREAT BASIN ESPECIALLY OVER THE HIGHER ELEVATIONS. OTHERWISE EXPECT
DRY CONDITIONS WITH A WARMING TREND THROUGH THE END OF THE WEEK. THE
WARMEST WEATHER OF THE YEAR SO FAR IS EXPECTED THIS WEEKEND.
&&

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT.

THE CONVECTIVE COMPLEX THAT GOT GOING YESTERDAY EVENING ACROSS SOUTH-
CENTRAL NEVADA HAS PUSHED TOWARD THE UTAH BORDER EARLY THIS MORNING
IN A SOMEWHAT DECAYED STATE. MOST OF THE MAIN COMPLEX WAS NOW JUST
AN AREA OF LIGHT TO MODERATE RAIN, HOWEVER, WE HAVE SEEN SOME CELLS
DEVELOP ON THE SOUTHERN FLANK OF THE MAIN AREA OF PRECIPITATION
ACROSS NORTHERN MOHAVE COUNTY IN THE LAST HOUR. BASED ON THE HRRR,
THIS ACTIVITY IS ALL SLATED TO MOVE EAST AND SHOULD EXIT THE AREA BY
LATER THIS MORNING. HOWEVER, A SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS WAS LEFT IN THE FORECAST FOR LINCOLN COUNTY AND ADDED
TO THE FORECAST FOR NORTHERN MOHAVE COUNTY TO ACCOUNT FOR THIS.
WHATEVER CLOUDS ARE AROUND FROM THIS SHOULD CLEAR OUT AS WELL BY
LATER THIS MORNING.

WE REMAIN IN A BROAD TROUGH IN THE MID AND UPPER LEVELS OF THE
ATMOSPHERE ACROSS THE SOUTHWEST. TWO FEATURES ARE OF NOTE THIS
MORNING. ONE IS THE MAIN JET STREAM WHICH IS PASSING BY TO OUR
SOUTH. THIS WILL PUSH A BAND OF HIGHER LEVEL MOISTURE ACROSS THE
SOUTHERN THIRD OF THE AREA TODAY INTO TONIGHT RESULTING IN HIGH
CLOUDS. SOME OF THE CLOUDS COULD ENHANCE OFF THE COASTAL RANGES OF
SOCAL BY LATER TODAY INTO TONIGHT AND THUS SKY COVER HERE MAY BE
UNDERDONE. THE SECOND FEATURE TO WATCH CAN BE SEEN ON WATER VAPOR
IMAGERY DIGGING SOUTH ACROSS NORCAL AND NORTHWESTERN NEVADA THIS
MORNING. THIS NEXT PIECE OF ENERGY WILL WORK SOUTH AND EAST ACROSS
THE SOUTHERN HALF OF NEVADA TODAY AND ONCE AGAIN WITH THE MOISTURE
(MAINLY MID-LEVEL) AND INSTABILITY IN PLACE HELP TO SPARK OFF
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS THIS AFTERNOON ACROSS THE
SOUTHERN GREAT BASIN ESPECIALLY OVER THE HIGHER ELEVATIONS. SIMILAR
TO YESTERDAY, ACTIVITY SHOULD PUSH WEST TO EAST ACROSS THE AREA.
INSPECTING THE HRRR AND LOCAL 4KM HIGH RESOLUTION ARW AND NMM
MODELS, THERE APPEARS TO BE TWO MAIN AREAS THAT WILL NEED TO BE
WATCHED THIS AFTERNOON. THE FIRST IS NORTHERN LINCOLN COUNTY AND THE
SECOND WILL BE ACROSS ESMERALDA COUNTY AS WELL AS THE WHITE
MOUNTAINS, NORTHERN OWENS VALLEY AND EASTERN SLOPES OF THE SOUTHERN
SIERRA NEVADA. POPS WERE RAISED SLIGHTLY FOR THE LATTER. THE MAIN
THREATS IN AND NEAR THUNDERSTORMS TODAY WILL BE GUSTY AND ERRATIC
WINDS TO 45 MPH, SMALL HAIL, LIGHTNING AND DOWNPOURS THAT COULD
PRODUCE LOCALIZED FLOODING. SHOWERS AND THUNDERSTORMS SHOULD
DECREASE THIS EVENING WITH THE LOSS OF HEATING. DESPITE THE TROUGH
OVERHEAD TEMPS WILL BE ON THE RISE TODAY WITH HIGHS RETURNING BACK
CLOSER TO NORMAL. THIS WILL SNAP THE SUB-90 STREAK IN LAS VEGAS THAT
HAS BEEN AROUND SINCE MAY 4TH. WITH TEMPS RISING, SNOW LEVELS WILL
BE AROUND 11000 FEET TODAY BUT ANY HEAVIER SHOWERS OVER THE HIGHEST
MOUNTAINS COULD AGAIN DROP A FEW INCHES OF SNOW. HIKERS AND OUTDOOR
ENTHUSIASTS IN THE SOUTHERN SIERRA NEVADA AND WHITE MOUNTAINS SHOULD
AGAIN BE ALERT FOR POTENTIAL WINTRY CONDITIONS ON AREA TRAILS AND
CAMPGROUNDS HIGHER UP.

A MID/UPPER LEVEL LOW WILL PUSH EAST ACROSS BAJA CALIFORNIA TONIGHT
AND HELP TO PUSH ANY CIRRUS ACROSS THE SOUTHERN HALF OF OUR AREA OFF
TO THE EAST ON WEDNESDAY, HOWEVER, SOME THICKER HIGH LEVEL CLOUDS
MAY START THE DAY OFF IN MOHAVE COUNTY. A BROAD MID/UPPER LEVEL
TROUGH WILL REMAIN ACROSS THE AREA FOR WEDNESDAY AND WITH ENERGY
RIPPLING THROUGH THE BASE OF THE TROUGH AND ENOUGH MOISTURE AS WELL
AS INSTABILITY REMAINING IN PLACE ONCE AGAIN RESULT IN SHOWERS AND
THUNDERSTORMS POPPING UP WITH THE HEATING OF THE DAY ACROSS THE
SOUTHERN GREAT BASIN. ONCE AGAIN EXPECT MAINLY AFTERNOON AND EVENING
ACTIVITY MAINLY OVER THE HIGHER ELEVATIONS. TEMPS WILL RISE A FEW
MORE DEGREES AS THE ATMOSPHERE CONTINUES TO WARM FURTHER. THIS
SHOULD PUSH HIGHS BACK CLOSER TO NORMAL AND I SIDED WITH THE WARMER
MAV (GFS) NUMBERS FOR HIGHS.

THE PESKY TROUGH ALOFT WILL FINALLY ALLOW FOR A FULL-FLEDGED FEEL OF
SPRING (MORE LIKE SUMMER DEPENDING ON YOUR TASTE AND HOW THIS SPRING
HAS BEEN) BY THURSDAY AS A RIDGE ALOFT STARTS TO TRANSITION IN. IF
YOU HAVE BEEN HOLDING OFF USING ON THE AIR CONDITIONER MUCH, GET
READY TO CRANK IT AS HIGHS SOAR TO ABOVE NORMAL READINGS FOR A
CHANGE. A WEAK RIPPLE IN THE FLOW AND LINGERING MOISTURE AND
INSTABILITY COULD STILL SET OFF A FEW SHOWERS AND THUNDERSTORMS IN
THE AFTERNOON AND EVENING OVER THE SOUTHERN GREAT BASIN, HOWEVER,
ACTIVITY SHOULD BE LESS IN AREAL COVERAGE COMPARED TO TUESDAY AND
WEDNESDAY. ONCE AGAIN ANY SHOWERS AND THUNDERSTORMS SHOULD END IN
THE EVENING WITH THE LOSS OF HEATING.

.LONG TERM...FRIDAY THROUGH TUESDAY.

THE STORY OF THE LONG TERM PERIOD WILL BE AFTERNOON HIGHS PUSHING
THE CENTURY MARK ACROSS MOST DESERT LOCALES THROUGH THE BEGINNING OF
NEXT WEEK...AS A SHORTWAVE RIDGE TRAVERSES OVER THE AREA THIS
WEEKEND. MINOR DIFFERENCES CONTINUE TO EXIST WITH OPERATIONAL
GUIDANCE REGARDING THE OVERALL AMPLITUDE OF THE AFOREMENTIONED
RIDGE. HOWEVER ALL BASE AND DERIVED GUIDANCE CONTINUES TO
CONSISTENTLY INDICATE HIGH TEMPERATURES AT LEAST WITHIN A FEW
DEGREES OF EACH OTHER FROM MODEL TO MODEL OVER THE WEEKEND...FURTHER
INCREASING CONFIDENCE OF THE FIRST 100 DEGREE DAY OF 2015 FOR MANY
DESERT LOCALES...INCLUDING LAS VEGAS. BOTH THE OPERATIONAL GFS/ECMWF
INDICATE A FAIRLY VIGOROUS TROUGH IMPINGING ON THE GREAT BASIN LATE
SUNDAY INTO MONDAY...WHICH WILL INCREASE SOUTHERLY/SOUTHWESTERLY
FLOW ACROSS MUCH OF THE CWA IN THIS TIMEFRAME. THIS WILL PROMOTE
GOOD MIXING...ESPECIALLY ON SUNDAY AFTERNOON...WHICH WILL BUMP UP
HIGH TEMPERATURES A FEW DEGREES FROM FRIDAY AND SATURDAY LIKELY
MAKING THIS THE HOTTEST DAY OF THE YEAR THUS FAR. TEMPERATURES WILL
COOL A FEW DEGREES MONDAY AND TUESDAY IN RESPONSE TO THE PASSING
TROUGH...BUT WILL REMAIN ABOVE SEASONAL NORMALS.
&&

.AVIATION...FOR MCCARRAN...WINDS SHOULD TURN SOUTHEAST LATE THIS
MORNING BETWEEN 120 AND 160 DEGREES TRUE DIRECTION THEN SHIFT MORE
TO THE SOUTH BETWEEN 170 AND 220 DEGREES AROUND 21Z TODAY AND
INCREASE TO 10-14 KTS WITH GUSTS TO AROUND 20 KTS. WINDS SHOULD
SLOWLY DECREASE THIS EVENING BETWEEN 05Z AND 07Z WEDNESDAY. A FEW
CLOUDS AOA 12K FEET THIS AFTERNOON WITH SCT-BKN CLOUDS AOA 25K FEET
LATER TONIGHT.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...MAINLY DIURNAL WIND DIRECTIONS THROUGH TONIGHT AT 12
KTS OR LESS. A FEW CLOUDS AOA 12K FEET TODAY WITH SCT-BKN CLOUDS AOA

ACROSS CENTRAL NYE COUNTY AND SOUTHERN ESMERALDA COUNTY. INFRARED
SATELLITE IMAGERY SHOWS CLOUD TOPS STILL COOLING IN SOME AREAS OF
ESMERALDA COUNTY AND QUITE A BIT OF LIGHTNING BEING PRODUCED SO POPS
WERE INCREASED ACROSS THE AREA FROM HIGHWAY 95 ON EAST ACROSS
ESMERALDA, NYE AND LINCOLN COUNTIES. IT APPEARS THIS ACTIVITY MAY GO

RAISED THERE AS WELL FOR LATER TONIGHT. THE CLOUD SHIELD FROM THIS
CONVECTIVE COMPLEX SHOULD ALSO FILL IN THE SKY ACROSS NORTHEAST
CLARK COUNTY IN THE NEXT FEW HOURS AS WELL AS NORTHERN MOHAVE COUNTY
SO CLOUD COVER WAS RAISED THERE AS WELL. WE WILL HAVE TO WATCH THE

A FEW SHOWERS AND ISOLATED THUNDERSTORMS HAVE DEVELOPED THIS
AFTERNOON OVER PORTIONS OF THE SOUTHERN GREAT BASIN...BUT OVERALL
THINGS ARE MUCH QUIETER THAN YESTERDAY. TROUGH CONTINUES TO PUSH EAST
AWAY FROM THE AREA THROUGH ARIZONA AS ANOTHER TROUGH MOVES INTO
NORTHERN NEVADA. THIS HAS BROUGHT WIDESPREAD THUNDERSTORMS TO
NORTHERN NEVADA AND THE NORTHERN SIERRA. SOME OF THIS ENERGY IS
EXPECTED TO BRUSH THE NORTHERN PORTIONS OF OUR FORECAST AREA THIS
EVENING AND WE SHOULD SEE AN INCREASE IN ACTIVITY ACROSS NORTHERN
INYO...ESMERALDA AND CENTRAL NYE COUNTIES. ANY REMAINING SHOWER
ACTIVITY ACROSS THE SOUTHERN ZONES SHOULD QUICKLY DIMINISH AFTER
SUNSET WITH LOSS OF HEATING. WEAK TROUGHINESS WILL REMAIN OVER THE
AREA TUESDAY WITH MAINLY DRY CONDITIONS OVER THE SOUTHERN ZONES.
THERE WILL BE ENOUGH ENERGY...MOISTURE AND INSTABILITY TO BRING A
FEW SHOWERS AND THUNDERSTORMS ONCE AGAIN TO THE SIERRA...
ESMERALDA...CENTRAL NYE AND LINCOLN COUNTIES. ALTHOUGH WE ARE
EXPECTED TO REMAIN UNDER THE INFLUENCE OF THE TROUGH THROUGH
THURSDAY ITS EXPECTED TO WEAKEN EACH DAY AND SHOWER AND THUNDERSTORM
COVERAGE WILL ALSO DECREASE EACH AFTERNOON FOR THE NORTHERN ZONES.
TEMPERATURES ARE STILL EXPECTED TO REMAIN SLIGHTLY BELOW NORMAL
TUESDAY AND WEDNESDAY...BUT WILL CLIMB TO AROUND NORMAL BY THURSDAY.

.LONG TERM...FRIDAY THROUGH MONDAY.

A HIGH PRESSURE RIDGE BUILDING OVER THE SOUTHWESTERN STATES WILL
BRING A LONG AWAITED RETURN OF WARM TEMPERATURES MORE TYPICAL OF
LATE MAY THAN OBSERVED THE PAST SEVERAL WEEKS. THIS MEANS
TEMPERATURES APPROACHING TRIPLE DIGITS IN THE DESERTS ARE A
POSSIBILITY...ESPECIALLY FOR THE LOWER DESERTS WHERE ITS PRETTY
CERTAIN TEMPERATURES WILL CLIMB INTO THE 100S. WIND SPEEDS LOOK
PRETTY LIGHT BOTH FRIDAY AND SATURDAY WHICH MAY LIMIT THE HIGH
TEMPERATURES A COUPLE DEGREES BUT WITH STRONGER WINDS FORECAST
SUNDAY AS A WEAK SHORTWAVE MOVES ACROSS THE GREAT BASIN...ENHANCED
MIXING SHOULD MAKE SUNDAY THE WARMEST DAY IN THE EXTENDED RANGE.
TEMPERATURES ON AVERAGE ACROSS THE REGION LOOK TO BE 7 TO 10 DEGREES
ABOVE NORMAL THROUGH THE WEEKEND. AS THE SHORTWAVE MOVING THROUGH
THE GREAT BASIN DEPARTS TO OUR EAST MONDAY AND FLATTENS OUT THE
RIDGE...TEMPERATURES WILL COOL SLIGHTLY BUT STILL REMAIN AT OR
SLIGHTLY ABOVE NORMAL.  WITH THE EXCEPTION OF A STRAY SHOWER
POSSIBLE IN THE SIERRA ON FRIDAY...CONDITIONS LOOK DRY THROUGH THE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
300 PM PDT MON MAY 25 2015

.SYNOPSIS...MOST AREAS WILL SEE A QUIETER WEATHER PATTERN THROUGH
THE UPCOMING WEEK. SHOWERS AND THUNDERSTORMS WILL BE MOSTLY LIMITED
TO THE SIERRA AND THE SOUTHERN GREAT BASIN MOUNTAINS WITH DRY
CONDITIONS EXPECTED ELSEWHERE. MORE SEASONABLE CONDITIONS ARE
EXPECTED BY MID WEEK AS TEMPERATURES RISE TO NEAR NORMAL BY
WEDNESDAY THEN TRANSITION TO ABOVE NORMAL LATER IN THE WEEK.
&&

.SHORT TERM...THROUGH FRIDAY MORNING.

A FEW SHOWERS AND ISOLATED THUNDERSTORMS HAVE DEVELOPED THIS
AFTERNOON OVER PORTIONS OF THE SOUTHERN GREAT BASIN...BUT OVERALL
THINGS ARE MUCH QUIETER THAN YESTERDAY. TROUGH CONTINUES TO PUSH EAST
AWAY FROM THE AREA THROUGH ARIZONA AS ANOTHER TROUGH MOVES INTO
NORTHERN NEVADA. THIS HAS BROUGHT WIDESPREAD THUNDERSTORMS TO
NORTHERN NEVADA AND THE NORTHERN SIERRA. SOME OF THIS ENERGY IS
EXPECTED TO BRUSH THE NORTHERN PORTIONS OF OUR FORECAST AREA THIS
EVENING AND WE SHOULD SEE AN INCREASE IN ACTIVITY ACROSS NORTHERN
INYO...ESMERALDA AND CENTRAL NYE COUNTIES. ANY REMAINING SHOWER
ACTIVITY ACROSS THE SOUTHERN ZONES SHOULD QUICKLY DIMINISH AFTER
SUNSET WITH LOSS OF HEATING. WEAK TROUGHINESS WILL REMAIN OVER THE
AREA TUESDAY WITH MAINLY DRY CONDITIONS OVER THE SOUTHERN ZONES.
THERE WILL BE ENOUGH ENERGY...MOISTURE AND INSTABILITY TO BRING A
FEW SHOWERS AND THUNDERSTORMS ONCE AGAIN TO THE SIERRA...
ESMERALDA...CENTRAL NYE AND LINCOLN COUNTIES. ALTHOUGH WE ARE
EXPECTED TO REMAIN UNDER THE INFLUENCE OF THE TROUGH THROUGH
THURSDAY ITS EXPECTED TO WEAKEN EACH DAY AND SHOWER AND THUNDERSTORM
COVERAGE WILL ALSO DECREASE EACH AFTERNOON FOR THE NORTHERN ZONES.
TEMPERATURES ARE STILL EXPECTED TO REMAIN SLIGHTLY BELOW NORMAL
TUESDAY AND WEDNESDAY...BUT WILL CLIMB TO AROUND NORMAL BY THURSDAY.

.LONG TERM...FRIDAY THROUGH MONDAY.

A HIGH PRESSURE RIDGE BUILDING OVER THE SOUTHWESTERN STATES WILL
BRING A LONG AWAITED RETURN OF WARM TEMPERATURES MORE TYPICAL OF
LATE MAY THAN OBSERVED THE PAST SEVERAL WEEKS. THIS MEANS
TEMPERATURES APPROACHING TRIPLE DIGITS IN THE DESERTS ARE A
POSSIBILITY...ESPECIALLY FOR THE LOWER DESERTS WHERE ITS PRETTY
CERTAIN TEMPERATURES WILL CLIMB INTO THE 100S. WIND SPEEDS LOOK
PRETTY LIGHT BOTH FRIDAY AND SATURDAY WHICH MAY LIMIT THE HIGH
TEMPERATURES A COUPLE DEGREES BUT WITH STRONGER WINDS FORECAST
SUNDAY AS A WEAK SHORTWAVE MOVES ACROSS THE GREAT BASIN...ENHANCED
MIXING SHOULD MAKE SUNDAY THE WARMEST DAY IN THE EXTENDED RANGE.
TEMPERATURES ON AVERAGE ACROSS THE REGION LOOK TO BE 7 TO 10 DEGREES
ABOVE NORMAL THROUGH THE WEEKEND. AS THE SHORTWAVE MOVING THROUGH
THE GREAT BASIN DEPARTS TO OUR EAST MONDAY AND FLATTENS OUT THE
RIDGE...TEMPERATURES WILL COOL SLIGHTLY BUT STILL REMAIN AT OR
SLIGHTLY ABOVE NORMAL.  WITH THE EXCEPTION OF A STRAY SHOWER
POSSIBLE IN THE SIERRA ON FRIDAY...CONDITIONS LOOK DRY THROUGH THE
PERIOD.
&&

.AVIATION...FOR MCCARRAN...ISOLATED SHOWERS AND THUNDERSTORMS WILL
BE AROUND PORTIONS OF SOUTHERN NEVADA THIS EVENING...BUT OUTSIDE OF
A LIGHT SPRINKLE MCCARRAN IS NOT EXPECTED TO SEE ANY PRECIPITATION.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
250 AM PDT MON MAY 25 2015

.SYNOPSIS...MOST AREAS WILL SEE A QUIETER WEATHER PATTERN THROUGH
THE UPCOMING WEEK. SHOWERS AND THUNDERSTORMS WILL BE MOSTLY LIMITED
TO THE SIERRA AND THE SOUTHERN GREAT BASIN MOUNTAINS WITH DRY
CONDITIONS EXPECTED ELSEWHERE. MORE SEASONABLE CONDITIONS ARE
EXPECTED THIS WEEK AS TEMPERATURES RISE TO NEAR NORMAL BY WEDNESDAY
THEN TRANSITION TO ABOVE NORMAL LATER IN THE WEEK.
&&

.SHORT TERM...THROUGH THURSDAY MORNING.

SHOWER AND CLOUD COVER TRENDS ARE DOWN THIS MORNING. AT 2 AM, RADAR
SHOWED ISOLATED SHOWERS FROM NEAR PAHRUMP TO NEAR LAUGHLIN AND NORTH
OF INTERSTATE 40 IN MOHAVE COUNTY. MODELS HAVE THESE SHOWERS MOVING
OUT OF THE AREA BY 9 AM. CLOUDS ARE COVERING MUCH OF INYO, SOUTHERN
CLARK AND MOHAVE COUNTIES EARLY THIS MORNING WITH CLOUDS EXPECTED TO
DIMINISH LATER IN THE MORNING AND THEN RE-DEVELOPING OVER THE
MOUNTAINS THIS AFTERNOON.

A QUIETER WEATHER PATTERN WILL GREET THE FIRST HALF OF THE WEEK AS
BROAD TROUGHING SETS UP OVER THE WEST. RISING HEIGHTS AND MORE
SUNSHINE WILL ALLOW TEMPERATURES TO PUSH CLOSER TO NORMAL TODAY
THROUGH WEDNESDAY. SHOWER CHANCES WILL MAINLY BE LIMITED TO THE
SIERRA AND THE SOUTHERN GREAT BASIN MOUNTAINS EACH AFTERNOON THROUGH
THE MIDDLE OF THE WEEK. LOCALLY BREEZY CONDITIONS ARE FORECAST EACH
AFTERNOON BUT ARE NOT EXPECTED TO BE WIDESPREAD OR OF ANY
SIGNIFICANCE.

.LONG TERM...THURSDAY AFTERNOON THROUGH MONDAY MORNING.

NORTHWEST FLOW WILL REIGN OVER THE REGION THURSDAY AFTERNOON...AS A
BROAD MID-UPPER LEVEL TROUGH MOVES OFF TO THE EAST OF THE AREA.
SUFFICIENT UPPER LEVEL SUPPORT AND MOISTURE...COMBINED WITH MARGINAL
INSTABILITY MAINLY IN THE HIGHER TERRAIN OF INYO AND EASTERN LINCOLN
COUNTIES WILL YIELD A SLIGHT CHANCE OF SHOWERS AND ISOLATED
THUNDERSTORMS THURSDAY AFTERNOON/EVENING.

THE STORY OF THE LONG TERM SWITCHES TO RISING TEMPERATURES ON
FRIDAY...AS A SHORTWAVE RIDGE BEGINS TO MOVE OVER THE AREA. OPTED TO
MOVE AWAY FROM CONS GUIDANCE IN TONIGHTS HIGH TEMPERATURE GRIDS...AS
THERE IS REASON TO BELIEVE THAT THERE IS A COOL BIAS GIVEN THE BELOW
AVERAGE TEMPERATURES AS OF LATE. ON THE OTHER HAND...MEX AND ECE
GUIDANCE CONTINUES TO HINT AT TEMPERATURES EXCEEDING THE CENTURY
MARK ACROSS MOST DESERT LOCALES SATURDAY AND SUNDAY...INCLUDING LAS
VEGAS. LOWER DESERT AND VALLEY LOCATIONS...SUCH AS DEATH
VALLEY...COULD VERY WELL APPROACH AND ECLIPSE THE 110 DEGREE MARK
THIS WEEKEND. AT THIS TIME...IT APPEARS THAT SUNDAY WILL BE THE
WARMEST DAY OF 2015 THUS FAR...AS AN INCREASE IN
SOUTHERLY/SOUTHWESTERLY FLOW AHEAD OF THE NEXT UPPER LEVEL TROUGH
WILL PROMOTE MIXING ACROSS THE AREA AND BUMP TEMPERATURES UP A FEW
DEGREES SUNDAY AFTERNOON.

DESPITE THE CONSISTENT SIGNALS IN GUIDANCE...THERE CONTINUES TO BE
NOTABLE DIFFERENCES IN THE AMPLIFICATION OF THE AFOREMENTIONED
SHORTWAVE RIDGE THAT IS SLATED TO MOVE OVER THE REGION...DUE MAINLY
TO A TROUGH MOVING OVER SOUTHERN BRITISH COLUMBIA/ALBERTA DURING THE
WEEKEND. AT THIS TIME...THE DIFFERENCES BETWEEN THE GFS AND ECMWF
HIGH TEMPERATURE SOLUTIONS ARE ONLY A FEW DEGREES EACH DAY THIS
WEEKEND...INCREASING CONFIDENCE IN HIGH TEMPERATURES RUNNING 7-10
DEGREES ABOVE NORMAL THIS WEEKEND...BARRING ANY MAJOR CHANGES THIS
WEEK. &&
.AVIATION...FOR MCCARRAN...SOUTHWEST WINDS UP TO 8KTS THROUGH THE
MORNING HOURS THEN BECOMING GUSTY OUT OF THE SOUTHWEST TO AROUND
20KTS THIS AFTERNOON. CLOUD COVER WILL DIMINISH AFTER 10Z. SHOWER
AND THUNDERSTORM CHANCES WILL PRIMARILY BE NORTH OF VEGAS WITH
SCATTERED SHOWERS POSSIBLE OVER THE CLARK COUNTY MOUNTAINS. SHOWERS
ARE NOT EXPECTED AT THE TERMINAL TODAY.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED SHOWERS TO CONTINUE OVER THE NEXT
SEVERAL HOURS...MAINLY ACROSS PORTIONS OF SOUTHERN CLARK AND MOHAVE
COUNTIES. THUNDERSTORM CHANCES WILL REMAIN IN THE FORECAST TODAY BUT
MAINLY ISOLATED AND LIMITED TO THE SIERRA AND SOUTHERN GREAT BASIN
MOUNTAINS.

850 PM PDT SUN MAY 24 2015

.SYNOPSIS...SHOWERS AND THUNDERSTORMS WILL BE MOSTLY LIMITED TO
THE SIERRA AND THE SOUTHERN GREAT BASIN FOR MUCH OF THE UPCOMING
WEEK WITH DRY CONDITIONS EXPECTED ELSEWHERE. BELOW NORMAL
TEMPERATURES MONDAY WILL TRANSITION TO ABOVE NORMAL LATER IN THE
WEEK.
&&

.UPDATE...ADJUSTED THE FORECAST BASED ON LATEST SATELLITE AND RADAR
TRENDS. SHOWERS AND STORMS ARE MOVING NORTHWEST TO SOUTHEAST THROUGH
THE SOUTHERN GREAT BASIN AND NORTHERN INYO COUNTY. FAR SOUTHERN
NEVADA INCLUDING CLARK COUNTY AND THE NORTHERN HALF OF MOHAVE COUNTY
ARE ALSO GETTING...OR WILL BE GETTING IN ON THE ACTION THIS EVENING.
IN GENERAL, SHOWERS WERE PRODUCING LIGHT RAIN AMOUNTS GENERALLY
UNDER A TENTH OF AN INCH BUT SENSORS UNDER THUNDERSTORMS WERE
REPORTING UPWARDS OF A THIRD OF AN INCH AS THE STORMS ROLLED OVER.
OUTFLOW WINDS UP TO 30 MPH ARE ALSO POSSIBLE FROM THUNDERSTORM
ACTIVITY THIS EVENING.
&&

.PREVIOUS DISCUSSION...312 PM PDT...

.SHORT TERM...THROUGH WEDNESDAY NIGHT. SATELLITE LOOP SHOWED
YESTERDAYS LOW MOVING EAST ALONG THE ARIZONA MEXICO BORDER WITH A
SECONDARY CIRCULATION DROPPING SOUTH THROUGH THE GREAT BASIN. AREA
RADARS SHOWED SHOWERS AND THUNDERSTORMS OVER CLARK...LINCOLN AND
MOHAVE COUNTIES MOVING GENERALLY SOUTHEAST. AFTER THE SECONDARY
CIRCULATION PASSES THROUGH TONIGHT...WEAK SHORTWAVE RIDGING MONDAY
WILL LIMIT THUNDERSTORM CHANCES TO THE HIGHER TERRAIN NEAR AND NORTH
OF LAS VEGAS. BY TUESDAY ANOTHER LOW PRESSURE SYSTEM WILL MOVE INTO
WASHINGTON STATE...BUT HEIGHTS WILL RISE A LITTLE MORE OVER OUR
AREA...PUSHING TEMPERATURES TO NEAR NORMAL FOR LATE MAY AND PUSHING
THUNDERSTORM CHANCES A LITTLE FARTHER NORTH THAN MONDAY. MODELS SHOW
THE LOW OVER WASHINGTON PHASING WITH A WEAK SOUTHERN STREAM TROUGH
MOVING INTO THE NORTHERN BAJA WEDNESDAY...FORMING A FULL LATITUDE
TROUGH OVER THE WEST. HOWEVER...THEY ALSO AGREE ON LITTLE CHANGE IN
SENSIBLE WEATHER FOR OUR AREA...WITH THUNDERSTORM CHANCES STILL
REMAINING NORTH OF LAS VEGAS AND TEMPERATURES EDGING UP A COUPLE
MORE DEGREES.

.LONG TERM...THURSDAY THROUGH SUNDAY.

WEAK TROUGH WILL STILL IMPACT THE REGION THURSDAY WITH LIMITED
MOISTURE AND WEAK INSTABILITY OVER MAINLY LINCOLN COUNTY AND THE
SIERRA CREST WHERE THE BEST CHANCES OF SHOWERS AND THUNDERSTORMS
WILL REMAIN. ALTHOUGH CHANCES ARE FAIRLY LIMITED AT LESS THAN 30
PERCENT IN THESE AREAS. THIS TROUGH IS EXPECTED TO EXIT THE REGION
THURSDAY NIGHT AS RIDGING BEGINS TO BUILD OVER THE AREA. AS THE
RIDGE CONTINUES TO BUILD TEMPERATURES WILL ALSO RISE THROUGH NEXT
WEEKEND. HIGH TEMPERATURES ON THURSDAY ARE EXPECTED TO BE A FEW
DEGREES ABOVE NORMAL...BUT BY THE WEEKEND ARE FORECAST TO BE AROUND
7-9 DEGREES ABOVE NORMAL. RIGHT NOW THERE ARE SOME DIFFERENCES
BETWEEN THE OPERATIONAL GFS/ECMWF MODELS WITH REGARDS TO THE
STRENGTH OF THE HIGH OVER THE WEEKEND. THE ECMWF TRIES TO WEAKEN THE
HIGH A BIT AS A TROUGH SKIRTS BY TO THE NORTH WHILE THE GFS KEEPS
THE HIGH FIRMLY OVER THE AREA. IF THE GFS VERIFIES TEMPERATURES
COULD EASILY REACH THE LOW 100S IN LAS VEGAS WITH 110 IN NEEDLES AND
BETWEEN 110-115 IN DEATH VALLEY. RIGHT NOW HAVE KEPT TEMPERATURES
SLIGHTLY ON THE CONSERVATIVE SIDE...BUT IF THE MODELS KEEP THE HIGH
IN PLACE THEN WE WILL SEE THOSE HOTTER TEMPERATURES.
&&

.AVIATION...FOR MCCARRAN...A FEW SHOWERS AND THUNDERSTORMS WILL BE
AROUND THROUGH THIS EVENING WITH THE POSSIBILITY OF ONE REACHING
WITHIN 3 SM OF THE TERMINAL. GUSTY OUTFLOW WINDS UP TO 30KTS WILL
ALSO BE POSSIBLE WITH ANY STORM. OUTSIDE OF ANY STORMS...WINDS WILL
REMAIN SOUTHWEST AROUND 10KTS WITH CIGS AROUND 10K FEET.
THUNDERSTORM CHANCES WILL BE AROUND AGAIN MONDAY...WITH A SLIGHT
CHANCE OF A THUNDERSTORM CLOSE TO MCCARRAN.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED SHOWERS TO CONTINUE THROUGH THE
EVENING...MAINLY ACROSS LINCOLN...INYO...CENTRAL NYE AND CLARK
COUNTIES. GUSTY OUTFLOW WINDS UP TO 35KTS WILL BE POSSIBLE WITH ANY
STORM AND CIGS AROUND 8-10K FEET. THUNDERSTORMS CHANCES WILL REMAIN
IN THE FORECAST MONDAY WITH MAINLY ISOLATED ACTIVITY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
312 PM PDT SUN MAY 24 2015

.SYNOPSIS...SHOWERS AND THUNDERSTORMS WILL BE MOSTLY LIMITED TO
THE SIERRA AND THE SOUTHERN GREAT BASIN FOR MUCH OF THE UPCOMING
WEEK WITH DRY CONDITIONS EXPECTED ELSEWHERE. BELOW NORMAL
TEMPERATURES MONDAY WILL TRANSITION TO ABOVE NORMAL LATER IN THE
WEEK.
&&

.SHORT TERM...THROUGH WEDNESDAY NIGHT. SATELLITE LOOP SHOWED
YESTERDAYS LOW MOVING EAST ALONG THE ARIZONA MEXICO BORDER WITH A
SECONDARY CIRCULATION DROPPING SOUTH THROUGH THE GREAT BASIN. AREA
RADARS SHOWED SHOWERS AND THUNDERSTORMS OVER CLARK...LINCOLN AND
MOHAVE COUNTIES MOVING GENERALLY SOUTHEAST. AFTER THE SECONDARY
CIRCULATION PASSES THROUGH TONIGHT...WEAK SHORTWAVE RIDGING MONDAY
WILL LIMIT THUNDERSTORM CHANCES TO THE HIGHER TERRAIN NEAR AND NORTH
OF LAS VEGAS. BY TUESDAY ANOTHER LOW PRESSURE SYSTEM WILL MOVE INTO
WASHINGTON STATE...BUT HEIGHTS WILL RISE A LITTLE MORE OVER OUR
AREA...PUSHING TEMPERATURES TO NEAR NORMAL FOR LATE MAY AND PUSHING
THUNDERSTORM CHANCES A LITTLE FARTHER NORTH THAN MONDAY. MODELS SHOW
THE LOW OVER WASHINGTON PHASING WITH A WEAK SOUTHERN STREAM TROUGH
MOVING INTO THE NORTHERN BAJA WEDNESDAY...FORMING A FULL LATITUDE
TROUGH OVER THE WEST. HOWEVER...THEY ALSO AGREE ON LITTLE CHANGE IN
SENSIBLE WEATHER FOR OUR AREA...WITH THUNDERSTORM CHANCES STILL
REMAINING NORTH OF LAS VEGAS AND TEMPERATURES EDGING UP A COUPLE
MORE DEGREES.

.LONG TERM...THURSDAY THROUGH SUNDAY.

WEAK TROUGH WILL STILL IMPACT THE REGION THURSDAY WITH LIMITED
MOISTURE AND WEAK INSTABILITY OVER MAINLY LINCOLN COUNTY AND THE
SIERRA CREST WHERE THE BEST CHANCES OF SHOWERS AND THUNDERSTORMS
WILL REMAIN. ALTHOUGH CHANCES ARE FAIRLY LIMITED AT LESS THAN 30
PERCENT IN THESE AREAS. THIS TROUGH IS EXPECTED TO EXIT THE REGION
THURSDAY NIGHT AS RIDGING BEGINS TO BUILD OVER THE AREA. AS THE
RIDGE CONTINUES TO BUILD TEMPERATURES WILL ALSO RISE THROUGH NEXT
WEEKEND. HIGH TEMPERATURES ON THURSDAY ARE EXPECTED TO BE A FEW
DEGREES ABOVE NORMAL...BUT BY THE WEEKEND ARE FORECAST TO BE AROUND
7-9 DEGREES ABOVE NORMAL. RIGHT NOW THERE ARE SOME DIFFERENCES
BETWEEN THE OPERATIONAL GFS/ECMWF MODELS WITH REGARDS TO THE
STRENGTH OF THE HIGH OVER THE WEEKEND. THE ECMWF TRIES TO WEAKEN THE
HIGH A BIT AS A TROUGH SKIRTS BY TO THE NORTH WHILE THE GFS KEEPS
THE HIGH FIRMLY OVER THE AREA. IF THE GFS VERIFIES TEMPERATURES
COULD EASILY REACH THE LOW 100S IN LAS VEGAS WITH 110 IN NEEDLES AND
BETWEEN 110-115 IN DEATH VALLEY. RIGHT NOW HAVE KEPT TEMPERATURES
SLIGHTLY ON THE CONSERVATIVE SIDE...BUT IF THE MODELS KEEP THE HIGH
IN PLACE THEN WE WILL SEE THOSE HOTTER TEMPERATURES.
&&

.AVIATION...FOR MCCARRAN...A FEW SHOWERS AND THUNDERSTORMS WILL BE
AROUND THROUGH THIS EVENING WITH THE POSSIBILITY OF ONE REACHING
WITHIN 3 SM OF THE TERMINAL. GUSTY OUTFLOW WINDS UP TO 30KTS WILL
ALSO BE POSSIBLE WITH ANY STORM. OUTSIDE OF ANY STORMS...WINDS WILL
REMAIN SOUTHWEST AROUND 10KTS WITH CIGS AROUND 10K FEET.
THUNDERSTORM CHANCES WILL BE AROUND AGAIN MONDAY...WITH A SLIGHT
CHANCE OF A THUNDERSTORM CLOSE TO MCCARRAN.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED SHOWERS TO CONTINUE THROUGH THE
EVENING...MAINLY ACROSS LINCOLN...INYO...CENTRAL NYE AND CLARK
COUNTIES. GUSTY OUTFLOW WINDS UP TO 35KTS WILL BE POSSIBLE WITH ANY
STORM AND CIGS AROUND 8-10K FEET. THUNDERSTORMS CHANCES WILL REMAIN
IN THE FORECAST MONDAY WITH MAINLY ISOLATED ACTIVITY.
&&

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

921 AM PDT SUN MAY 24 2015

.SYNOPSIS...SHOWERS AND THUNDERSTORMS WILL BE MOSTLY LIMITED TO
THE SIERRA AND THE SOUTHERN GREAT BASIN FOR MUCH OF THE UPCOMING
WEEK WITH DRY CONDITIONS EXPECTED ELSEWHERE. BELOW NORMAL
TEMPERATURES TODAY AND MONDAY WILL TRANSITION TO ABOVE NORMAL
LATER IN THE WEEK.
&&

.UPDATE...RAISED POPS FOR THIS AFTERNOON OVER NORTHEAST SAN
BERNARDINO COUNTY AND THE HIGHER TERRAIN OF CENTRAL AND SOUTHERN
MOHAVE COUNTY. BAND OF SHOWERS WAS CURRENTLY MOVING SOUTH THROUGH
NORTH CENTRAL MOHAVE COUNTY...AND HIGH RES MODELS SUGGEST
THUNDERSTORM DEVELOPMENT OVER THE MOJAVE PRESERVE THIS AFTERNOON. NO
OTHER CHANGES AT THIS TIME.
&&

.PREV DISCUSSION...
252 AM PDT SUN MAY 24 2015

.SHORT TERM...THROUGH TUESDAY NIGHT.

AN UPPER DISTURBANCE RESPONSIBLE FOR ONGOING SHOWER ACTIVITY
TONIGHT WILL BY OVER SOUTHEAST CALIFORNIA BY 5 AM THIS MORNING AND
THEN OUT OF OUR HAIR BY THIS AFTERNOON. HOWEVER, CLOUDS AND SHOWERS
WILL CONTINUE TO WRAP AROUND THE BACK SIDE OF LOW PRESSURE OVER THE
NORTHERN AND CENTRAL ROCKIES LEADING TO A FEW SHOWERS IN THE SIERRA,
THE SOUTHERN GREAT BASIN AND POSSIBLY THE MOUNTAINS OF CLARK COUNTY
INTO NORTHWESTERN ARIZONA TODAY. AS THIS WHOLE CONGLOMERATION OF
WEATHER MAKERS MOVES EAST OF THE ROCKIES BY MONDAY, ANOTHER SYSTEM
ENTERS THE PACIFIC NORTHWEST AND PROVIDES SUFFICIENT FORCING FOR
MORE SHOWERS AND STORMS OVER THE SIERRA AND THE SOUTHERN GREAT
BASIN MONDAY AND TUESDAY. ALTHOUGH A SOMEWHAT ACTIVE WEATHER PATTERN
PERSISTS, WARMER CONDITIONS ARE STILL EXPECTED. TEMPERATURES WILL BE
SIMILAR...IF NOT A FEW DEGREES WARMER TODAY AND THEN APPROACH
NORMAL MONDAY AND TUESDAY. IT LOOKS LIKE THE 70S IN VEGAS ARE
OVER FOR AWHILE AND AFTER ONLY A FEW BRIEF DAYS IN THE 80S,
TEMPERATURES WILL WARM BACK TO WHERE THEY SHOULD BE FOR THIS TIME
OF YEAR.

.LONG TERM...WEDNESDAY AFTERNOON THROUGH SUNDAY MORNING.

OPERATIONAL MODEL GUIDANCE CONTINUES TO BE IN GOOD AGREEMENT TONIGHT
IN HAVING A RELATIVELY WEAK MID TO UPPER LEVEL TROUGH TRAVERSING
ACROSS THE DESERT SOUTHWEST AT THE BEGINNING OF THE LONG TERM
PERIOD. LINGERING MOISTURE...INSTABILITY...AND SUFFICIENT UPPER
LEVEL FLOW WILL WARRANT AFTERNOON SHOWER AND ISOLATED THUNDERSTORM
CHANCES IN THE HIGHER TERRAIN ACROSS THE NORTHERN INYO AND GREAT
BASIN ZONES WEDNESDAY THROUGH THURSDAY AFTERNOON. THIS TROUGH WILL
EXIT THE REGION THURSDAY NIGHT...ALLOWING A RATHER AMPLIFIED
SHORTWAVE RIDGE TO BEGIN TO BUILD INTO OUR AREA FRIDAY.

UPPER LEVEL FLOW WILL TRANSITION FROM NORTHWESTERLY FRIDAY AS THE
RIDGE AXIS SLIDES OVER THE GREAT BASIN AND DESERT
SOUTHWEST...ALLOWING TEMPERATURES ACROSS THE AREA TO CONTINUE A
WARMING TREND THROUGH THE WEEKEND. GENERALLY...AFTERNOON HIGHS WILL
RUN 5-8 DEGREES ABOVE NORMAL FOR LATE MAY ACROSS MOST AREAS...WITH
MOST DESERT LOCALES RISING INTO THE UPPER 90S AND LOWER DESERT
LOCATIONS...LIKE DEATH VALLEY...RISING INTO THE MID TO UPPER 100S.
WHILE IT CONTINUES TO BE A POSSIBILITY THAT LAS VEGAS WILL BE ONE OF
THE LOCALES APPROACHING THE CENTURY MARK THIS WEEKEND...DETAILS IN
THE FORECAST...INCLUDING THE TIMING OF THE NEXT UPPER LEVEL
TROUGH...NEED TO BE RESOLVED AS THEY WILL PLAY A ROLE IN HOW HIGH
TEMPERATURES GET. AN INCREASE IN SOUTHWESTERLY FLOW WITH AN
APPROACHING TROUGH THIS WEEKEND WOULD INCREASE MIXING AND INCREASE
CHANCES OF THE FIRST 100 DEGREE DAY OF THE YEAR FOR LAS VEGAS. THIS
WILL BE SOMETHING TO KEEP AN EYE ON THIS WEEK AS THE FINER DETAILS
BECOME MORE CLEAR.

.AVIATION...FOR MCCARRAN...A FEW SHOWERS ARE POSSIBLE IN THE
VALLEY THIS MORNING WITH CIGS GENERALLY 8-10K FEET. WEST TO
SOUTHWEST WINDS UP TO 10KTS THROUGH 15Z THEN LIGHT AND VARIABLE
BEFORE TURNING BACK THE SOUTH AND INCREASING TO AROUND 10KT THIS
AFTERNOON. SOME ISOLATED SHOWER ACTIVITY IS POSSIBLE AGAIN
TODAY...BUT SHOULD MAINLY BE NORTH AND EAST OF LAS VEGAS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED SHOWERS TO CONTINUE THROUGH
THE MORNING WITH ISOLATED THUNDERSTORMS LATER TODAY MAINLY ACROSS
INYO...NYE...ESMERALDA AND LINCOLN COUNTIES WITH LESSER CHANCES
SOUTH. ANY SHOWER/TSTORM HAS THE POTENTIAL OF PRODUCING WIND GUSTS
TO 25KTS. AWAY FROM CONVECTIVE INFLUENCES WINDS ARE EXPECTED TO
REMAIN SOUTH/SOUTHWEST AROUND 10-20KTS WITH CIGS AROUND 8-10K FEET.

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