AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
138 PM PDT SAT MAR 28 2015

.SYNOPSIS...

WEAK LOW PRESSURE WILL BRING TEMPERATURES DOWN A FEW DEGREES FROM
FRIDAY, BUT HIGHS WILL REMAIN WELL ABOVE NORMAL THROUGH THIS
WEEKEND. ANOTHER LOW PRESSURE WILL BRING INCREASING WINDS LATE
MONDAY INTO TUESDAY WITH TEMPERATURES COOLING TO NEAR NORMAL BY
MIDWEEK.

&&

.SHORT TERM...
SLIGHTLY COOLER CONDITIONS FOR TODAY COMPARED TO FRIDAY, BUT HIGH
TEMPERATURES WILL STILL BE IN THE 70S ACROSS WESTERN NEVADA AND IN
THE 60S FOR THE SIERRA. SIMILAR TEMPERATURES ARE EXPECTED TOMORROW
AFTERNOON WITH LIGHT WINDS FOR BOTH DAYS. A WEAK SHORTWAVE MOVES
ACROSS THE SIERRA AND WESTERN NEVADA TODAY BRINGING SLIGHT CHANCES
FOR SHOWERS TO DEVELOP ACROSS THE SIERRA. WE ARE EXPECTING MOSTLY
CUMULUS BUILDUPS, BUT ANY SHOWERS THAT DO DEVELOP WILL BE RELATIVELY
SHORT-LIVED AND WEAK, AS THE MOISTURE/INSTABILITY AREN`T
SUBSTANTIAL. REMNANTS OF INSTABILITY AND MOISTURE WILL STICK AROUND
THROUGH MONDAY AFTERNOON, SO MAINTAINED SLIGHT CHANCES FOR SHOWERS
IN THE LATE AFTERNOONS ON SUNDAY AND MONDAY CONFINED TO THE SIERRA
CREST FROM TAHOE SOUTHWARD.

A LOW PRESSURE SYSTEM APPROACHES THE WEST COAST BRINGING AN INCREASE
TO THE WINDS FOR MONDAY AND TUESDAY. INCREASED WINDS AND IMPROVED
MIXING ON MONDAY WILL ALLOW FOR TEMPERATURES TO WARM UP TO NEAR THE
80 DEGREE MARK FOR WESTERN NEVADA VALLEYS AGAIN. TYPICAL AFTERNOON
WIND GUSTS (20-25 MPH) ARE EXPECTED ON MONDAY, WHILE STRONGER WIND
GUSTS (30-40 MPH) ARE FORECAST FOR TUESDAY AS THE UPPER LEVEL JET
EDGES INTO THE NORTHERN PORTION OF THE REGION. THE MAIN ENERGY FROM
THE LOW PRESSURE SYSTEM WILL REMAIN NORTH ACROSS THE PACIFIC
NORTHWEST, LEAVING US WITH MOSTLY WINDS AND ONLY SLIGHT CHANCES FOR
PRECIPITATION NORTH OF A GERLACH TO SUSANVILLE LINE. WEISHAHN

.LONG TERM...WEDNESDAY THROUGH SATURDAY...

A STORM MOVING OUT OF OREGON INTO NORTHERN NEVADA WEDNESDAY WILL
BRING A COLD POOL ALOFT WITH LOWER SNOW LEVELS AND COOLER SURFACE
TEMPERATURES. THE COLD AIR ALOFT COULD CREATE ENOUGH INSTABILITY
FOR SHOWERS AND POSSIBLY AN ISOLATED THUNDERSTORM MAINLY ACROSS
NORTHERN WASHOE AND PERSHING COUNTIES WITH SNOW LEVELS IN THE 4,000
TO 5,000 FOOT RANGE.

LIGHT NORTHERLY WIND WILL BRING EVEN COOLER AIR ACROSS THE EASTERN
SIERRA AND WESTERN NV ON THURSDAY. WE EXPECT THURSDAY TO BE THE
COOLEST DAY OF THE WEEK, WITH AFTERNOON HIGHS FORECAST AROUND 60 IN
WESTERN NV AND IN THE LOW-TO-MID 50S FOR EASTERN SIERRA
COMMUNITIES. THE AIR MASS SHOULD WARM SLIGHTLY FRIDAY BUT THEN
MID-RANGE MODELS SHOW ANOTHER COLD FRONT ARRIVING SATURDAY OR
SATURDAY NIGHT. THIS COLD-FRONTAL SYSTEM COULD TRACK FARTHER SOUTH
THAN THE PREVIOUS (MID-WEEK) SYSTEM, WITH THE BEST CHANCES FOR
SHOWERS NORTH OF I-80. THE PATTERN ACROSS THE PACIFIC, ZONAL AND
PROGRESSIVE, DOES NOT TYPICALLY OPEN THE DOOR TO SIGNIFICANT
SUBTROPICAL MOISTURE. AS SUCH, THE SATURDAY-SATURDAY NIGHT SYSTEM
DOES NOT LOOK LIKE A MAJOR PRECIPITATION PRODUCER. JCM

&&

.AVIATION...
VFR CONDITIONS WILL PREDOMINATE THIS WEEKEND. RESIDUAL
MOISTURE AND EASTERLY UPSLOPE FLOW MAY RESULT IN ISOLATED SHOWERS
ALONG THE SIERRA CREST FROM THE TAHOE BASIN SOUTH THIS EVENING.
ANOTHER WEAK TROUGH OF LOW PRESSURE APPROACHES SUNDAY WITH ANOTHER
ROUND OF ISOLATED SHOWERS POSSIBLE OVER THE SIERRA IN THE EVENING.

THE RIDGE THAT CONTRIBUTED TO RECORD HIGHS YESTERDAY IS WEAKENING
AS ELONGATED TROUGH MOVES ACROSS THE WESTERN U.S. TODAY. WHILE MOST
OF THE ENERGY ASSOCIATED WITH THIS TROUGH WILL REMAIN OVER THE
PACIFIC NORTHWEST, A WEAK IMPULSE IS STILL PROJECTED TO APPROACH
THE CENTRAL SIERRA THIS AFTERNOON AND LINGER THROUGH SUNDAY WITH
CUMULUS BUILDUPS NEAR THE SIERRA CREST BOTH DAYS. THERE IS A
SLIGHT POSSIBILITY FOR A FEW LATE DAY HIGH ELEVATION SHOWERS, BUT
ANYTHING THAT DEVELOPS WILL BE SHORT LIVED DUE TO LIMITED MOISTURE
AND AVAILABILITY. OTHERWISE, DRY CONDITIONS WILL PREVAIL THIS
WEEKEND WITH TEMPERATURES A FEW DEGREES COOLER THAN YESTERDAY,
BUT STILL 10-15 DEGREES ABOVE AVERAGE FOR LATE MARCH.

FOR MONDAY, A STRONGER TROUGH APPROACHING THE WEST COAST WILL
BRING INCREASING WINDS DURING THE AFTERNOON ALONG WITH AREAS OF
CIRRUS. WITH IMPROVED MIXING AND 700 MB TEMPS WARMING TO SIMILAR
VALUES THAT OCCURRED YESTERDAY, SOME LOWER ELEVATION SITES COULD

POPS...TEMPS AND SNOW LEVELS FROM TUESDAY THROUGH THURSDAY.

THERE COULD BE SOME VERY LIGHT PCPN ACROSS THE FAR NORTH WITH THE
FIRST WAVE TUESDAY...BUT IT MAINLY SERVES TO LOWER TEMPS AND INCREASE
WINDS FOR MOST OF THE REGION. THE ECMWF DIGS A STRONGER WAVE SOUTH
INTO THE FORECAST AREA WEDNESDAY NIGHT; IT IS THE MOST AGGRESSIVE OF
THE MODELS. THE GEM AND GFS ARE A LITTLE SLOWER WITH THIS FEATURE

SURFACE TEMPERATURES ARE NOT AS LIKELY TO REFLECT THE COLDER TEMPS

.SYNOPSIS...
A LOW PRESSURE SYSTEM WILL BRUSH THE AREA TONIGHT AND PUSH A WEAK
COLD FRONT THROUGH THE REGION. TEMPERATURES WILL BE SLIGHTLY
COOLER THIS WEEKEND ALTHOUGH STILL WELL ABOVE NORMAL. ANOTHER LOW
PRESSURE SYSTEM WILL APPROACH EARLY NEXT WEEK WITH WINDS BECOMING
GUSTY LATE MONDAY INTO TUESDAY.

&&

.SHORT TERM...
ONLY MINOR CHANGES TO THE FORECAST AS MOST OF THE MODEL DATA SHOW
PERSISTENCE THROUGH THE WEEKEND. GUSTY WINDS WILL DIMINISH AT
LOWER ELEVATIONS LATER THIS EVENING AS TEMPERATURES COOL, BUT WILL
STAY STEADY OR INCREASE SLIGHTLY AT UPPER ELEVATIONS AS A TROUGH
BUSHES THE REGION OVERNIGHT. A FEW SHOWERS MAY LINGER ALONG THE
COLD FRONT AS IT SLIDES SOUTHWARD INTO FAR NORTHEAST CA AND FAR
NORTHWEST NV, BUT WHAT DOES MAKE IT INTO THESE AREAS WILL BE VERY
LIGHT. OTHERWISE, IT WILL BE A LITTLE COOLER SATURDAY AS THE FRONT
BRINGS IN SLIGHTLY COOLER AIR ON LIGHT NORTHEAST WINDS.

SOME WEAK INSTABILITY AND FORCING REMAIN ALONG THE SIERRA CREST,
MAINLY SOUTH OF LAKE TAHOE AS TEMPERATURES COOL ALOFT UNDER TROUGH
AND CONVERGENCE INCREASES ALONG THE SIERRA CREST. THE BEST CHANCE
FOR SHOWERS REMAINS SUNDAY AS TEMPERATURES BEGIN TO REBOUND AT
LOWER LEVELS. WE MAINTAINED A SLIGHT CHANCE OF SHOWERS FOR A FEW
HOURS LATE SATURDAY AND AGAIN ON SUNDAY AFTN/EVENING FOR MONO
COUNTY. CONFIDENCE IS LOW WITH SHOWERS, BUT SOME CUMULUS
DEVELOPMENT IS LIKELY.

AS WE GO INTO MONDAY, ANOTHER TROUGH WILL BE APPROACHING. MODELS
DIFFER SOME ON THE TIMING, BUT IT DOES APPEAR RIDGE WINDS WILL
BEGIN TO INCREASE LATE IN THE DAY INTO MONDAY NIGHT WITH LOCALLY
BREEZY CONDITIONS ALONG THE SIERRA FRONT NORTHWARD LATE MONDAY
AFTERNOON AND EVENING. TEMPERATURES WILL WARM ONCE AGAIN WITH SOME
MODEL GUIDANCE PUSHING HIGHS BACK CLOSE TO 80 DEGREES IN WESTERN
NV. HOHMANN

.LONG TERM...TUESDAY THROUGH FRIDAY...
A MORE PROGRESSIVE UPPER LEVEL FLOW PATTERN LOOKS TO BE IN STORE
FOR NEXT WEEK. THIS WILL PROVIDE THE POTENTIAL FOR A FEW MINOR
DISTURBANCES TO PUSH ACROSS THE REGION AND MAY PRODUCE SOME
COOLING, LIGHT PRECIPITATION, AND INCREASED WINDS.

THE FIRST DISTURBANCE ON TUESDAY IS SHOWING BETTER AGREEMENT
AMONGST NUMERICAL GUIDANCE AND AS A RESULT WE ADDED A SLIGHT
CHANCE FOR SHOWERS MAINLY ACROSS LASSEN COUNTY INTO FAR NORTHERN
WASHOE COUNTY. NOT LOOKING LIKE SIGNIFICANT PRECIPITATION AMOUNTS
WITH THIS SYSTEM WITH AMOUNTS ON THE ORDER OF A FEW HUNDREDTHS.
THIS SYSTEM LOOKS TO PROVIDE A BETTER POTENTIAL FOR SOME GUSTY
WINDS AS THE TROUGH HELPS ESTABLISH AN ENHANCED SURFACE PRESSURE
GRADIENT. HAVE INCREASED WINDS FOR TUESDAY WHICH COULD CREATE SOME
HAZARDOUS BOATING ON AREA LAKES.

LESS AGREEMENT EXISTS BEYOND WEDNESDAY AS THE EC MODEL TRIES TO
DROP ANOTHER SHORTWAVE ACROSS THE AREA ON WEDNESDAY. THIS IS THE
FIRST RUN THE EC HAS DEVELOPED THIS WAVE THIS FAR SOUTH WHILE THE
GFS HAS KEPT THE DISTURBANCE FARTHER NORTH. NOT ENOUGH SUPPORT IN
ENSEMBLES OR RUN CONSISTENCY TO LATCH ONTO THE EC SOLUTION SO WILL
CONTINUE WITH THE CURRENT FORECAST OF INCREASED CLOUDS AND COOLER
CONDITIONS. FOR THURSDAY AND FRIDAY, WE WILL MAINTAIN A ZONAL FLOW
WITH PERIODS OF CLOUDS AND A DEGREE OR TWO OF WARMING INTO THE
START OF NEXT WEEKEND. FUENTES

JUST A MINOR UPDATE THIS MORNING TO ADD AREAS OF FREEZING FOG
AROUND TRUCKEE. THE FOG DOES NOT SEEM TO BE AS WIDESPREAD AS A

.PREVIOUS DISCUSSION... /ISSUED 311 AM PDT FRI MAR 27 2015/

SYNOPSIS...
BREEZY, WARM AND DRY CONDITIONS ARE ON TAP FOR THIS AFTERNOON
ACROSS NORTHEAST CALIFORNIA AND WESTERN NEVADA AS LOW PRESSURE
APPROACHES THE PACIFIC NORTHWEST COAST. THE WEAK LOW PRESSURE WILL
BRING SLIGHTLY COOLER TEMPERATURES FOR THE WEEKEND INTO EARLY NEXT
WEEK ALTHOUGH HIGHS WILL REMAIN WELL ABOVE NORMAL.

SHORT TERM...
THE MAIN SHORT TERM FORECAST CHANGES INCLUDE INCREASING WINDS
SLIGHTLY FOR MANY AREAS TONIGHT AND NARROWING DOWN TIMING FOR
ISOLATED SHOWERS NEAR THE ALPINE/MONO COUNTY CREST OVER THE
WEEKEND.

THE ABSURDLY WARM CONDITIONS CONTINUE TODAY UNDER A STRONG HIGH
PRESSURE RIDGE, WITH SOME DAILY HIGH TEMPERATURE RECORDS LIKELY
TO FALL. THIS AFTERNOON AND EVENING, AN UPPER TROUGH WILL BE
APPROACHING THE PACIFIC NORTHWEST COAST AS THE RIDGE BEGINS TO
SHIFT INTO EASTERN NEVADA AND UTAH. THE RESULTANT INCREASE IN THE
THERMAL GRADIENT IS EXPECTED TO BRING WINDS OF 10-20 MPH WITH GUSTS
30-35 MPH, ESPECIALLY NORTH OF HIGHWAY 50 INTO FAR WESTERN NEVADA.

FOR TONIGHT, WEAK LOW PRESSURE WILL MOVE THROUGH OREGON AND
WASHINGTON. WITH 700 MB WINDS PICKING UP TO BETWEEN 30-40 KTS NORTH
OF HIGHWAY 50 OVERNIGHT, THE ATMOSPHERE MAY STAY A BIT MIXED UP
WITH WINDS REMAINING ELEVATED FOR MID SLOPES AND RIDGES. AS FAR AS
PRECIPITATION, A FEW LIGHT SHOWERS ARE STILL POSSIBLE NORTH OF
SUSANVILLE AND GERLACH LATE TONIGHT AND EARLY SATURDAY AS A SURFACE
FRONT BRIEFLY LINES UP WITH WEAK FORCING AT THE TAIL END OF THE
OREGON/WASHINGTON TROUGH.

SATURDAY, A MILD PACIFIC HIGH BUILDS INTO NEVADA AND NORTHEAST
CALIFORNIA. LIGHT NORTHEAST LOW LEVEL FLOW AND LOWER TEMPERATURES
ALOFT WILL BRING SLIGHTLY COOLER TEMPERATURES. I HAVE LEFT THE
SLIGHT CHANCE FOR SHOWERS NEAR THE SIERRA CREST SOUTH OF HIGHWAY
50 FOR A FEW HOURS SATURDAY EVENING FOR CONSISTENCY SAKE. HOWEVER,
ONLY THE GFS SHOWS ANY HINT OF PRECIPITATION SO IT MAY WIND UP JUST
BEING SCATTERED CUMULUS.

ON SUNDAY, WELL ABOVE AVERAGE SURFACE TEMPERATURES AND FAIRLY COOL
TEMPERATURES IN THE MID LEVELS MAY ALLOW FOR A BETTER SHOT AT A
FEW DIURNALLY-LINKED SHOWERS NEAR THE CREST OF MONO COUNTY.
INSTABILITY LOOKS MEEK SO THUNDERSTORM CHANCES LOOKS REMOTE AT
THIS TIME. SNYDER

LONG TERM...MONDAY THROUGH THURSDAY...
MEDIUM RANGE MODELS ARE STARTING TO SHOW BETTER AGREEMENT WITH
REGARD TO A SERIES OF WAVES MOVING OVER THE TOP OF A FLAT RIDGE
DURING THE EXTENDED PERIOD. MINOR CHANGES WERE MADE TO TREND TOWARD
A SLIGHTLY WETTER SOLUTION BY THE END OF THE PERIOD AS CONFIDENCE
BEGINS TO INCREASE.

SHORT WAVE RIDGE FOR MONDAY SLIDES EAST AS A WAVE MOVES TOWARD THE
WEST COAST. MONDAY SHOULD BE THE WARMEST DAY OF THE EXTENDED WITH
HIGH TEMPS 10-15 DEGREES ABOVE AVERAGE. WINDS INCREASE MONDAY
EVENING AHEAD OF THIS SHORT WAVE SO OVERNIGHT LOWS WILL STAY MILD
THROUGH TUESDAY MORNING.

THE PASSAGE OF THIS FIRST WAVE TO THE NORTH OF THE CWA WILL DO
LITTLE MORE THAN LOWER HIGH TEMPS 8-10 DEGREES FOR TUESDAY...
ALTHOUGH THAT IS STILL ABOVE AVERAGE. A WEAK SECONDARY WAVE PUSHES
ACROSS EARLY WEDNESDAY AND KEEPS THESE TEMPS DOWN A BIT.

MODELS HAVE NOW CONVERGED ON A STRONGER WAVE THAT DIVES EAST
SOUTHEAST INTO THE GREAT BASIN ON THURSDAY. THIS BRINGS MUCH COLDER
AIR INTO FAR NORTHERN AND NORTHEAST NEVADA WITH NORTHWEST AND
CENTRAL NEVADA ON THE FRINGE OF THIS COLDER AIR. THIS WAVE IS ALSO
A BIT MORE DYNAMIC WITH ENOUGH FORCING TO PRODUCE SHOWERS OVER THE
FAR NORTHERN AND NORTHEAST CWA THURSDAY AFTERNOON AND EVENING.
SLIGHT CHANCE POPS WERE ADDED NORTH AND WEST OF A BIEBER TO GERLACH
TO LOVELOCK TO AUSTIN LINE FOR THURSDAY. 20

AVIATION...
RIDGE OVERHEAD THIS MORNING BEGINS TO SHIFT EAST AS A TROUGH OF LOW
PRESSURE MOVES ACROSS THE NORTHERN PART OF THE FORECAST AREA TONIGHT
INTO SATURDAY. VFR CONDITIONS SHOULD PERSIST TODAY FOR ALL BUT THE
EARLY MORNING HOURS IN FAVORED FOG PRONE SIERRA VALLEYS WHERE SHALLOW
FOG WILL CREATE OCCASIONAL IFR CONDITIONS.

SFC AND RIDGE WINDS BEGIN TO INCREASE THIS AFTERNOON AHEAD OF THE
TROUGH OF LOW PRESSURE WITH SFC GUSTS OF 25-30 KTS NORTH OF HIGHWAY
50 AND WEST OF HIGHWAY 95. RIDGE GUSTS COULD REACH 50 KTS BY EARLY
EVENING WITH TURBULENCE LIKELY OVER AND EAST OF THE SIERRA AND
HIGHER RANGES IN FAR NORTHEAST CALIFORNIA AND WESTERN NEVADA.

ISOLATED SHOWERS ARE POSSIBLE OVER THE FAR NORTHERN PART OF THE
FORECAST AREA LATE TONIGHT...NORTH OF SUSANVILLE...WITH A FEW
ISOLATED SHOWERS IN THE SIERRA SOUTH OF TAHOE FOR SATURDAY EVENING.
THESE SHOWERS COULD BRIEFLY REDUCE CIGS/VSBYS TO MVFR OR LESS. MORE

AHEAD OF THIS SHORT WAVE SO OVERNIGHT LOWS WILL STAY MILD THROUGH

.SYNOPSIS...
BREEZY, WARM AND DRY CONDITIONS ARE ON TAP FOR THIS AFTERNOON
ACROSS NORTHEAST CALIFORNIA AND WESTERN NEVADA AS LOW PRESSURE
APPROACHES THE PACIFIC NORTHWEST COAST. THE WEAK LOW PRESSURE WILL
BRING SLIGHTLY COOLER TEMPERATURES FOR THE WEEKEND INTO EARLY NEXT
WEEK ALTHOUGH HIGHS WILL REMAIN WELL ABOVE NORMAL.

&&

.SHORT TERM...
THE MAIN SHORT TERM FORECAST CHANGES INCLUDE INCREASING WINDS
SLIGHTLY FOR MANY AREAS TONIGHT AND NARROWING DOWN TIMING FOR
ISOLATED SHOWERS NEAR THE ALPINE/MONO COUNTY CREST OVER THE
WEEKEND.

THE ABSURDLY WARM CONDITIONS CONTINUE TODAY UNDER A STRONG HIGH
PRESSURE RIDGE, WITH SOME DAILY HIGH TEMPERATURE RECORDS LIKELY
TO FALL. THIS AFTERNOON AND EVENING, AN UPPER TROUGH WILL BE
APPROACHING THE PACIFIC NORTHWEST COAST AS THE RIDGE BEGINS TO
SHIFT INTO EASTERN NEVADA AND UTAH. THE RESULTANT INCREASE IN THE
THERMAL GRADIENT IS EXPECTED TO BRING WINDS OF 10-20 MPH WITH GUSTS
30-35 MPH, ESPECIALLY NORTH OF HIGHWAY 50 INTO FAR WESTERN NEVADA.

FOR TONIGHT, WEAK LOW PRESSURE WILL MOVE THROUGH OREGON AND
WASHINGTON. WITH 700 MB WINDS PICKING UP TO BETWEEN 30-40 KTS NORTH
OF HIGHWAY 50 OVERNIGHT, THE ATMOSPHERE MAY STAY A BIT MIXED UP
WITH WINDS REMAINING ELEVATED FOR MID SLOPES AND RIDGES. AS FAR AS
PRECIPITATION, A FEW LIGHT SHOWERS ARE STILL POSSIBLE NORTH OF
SUSANVILLE AND GERLACH LATE TONIGHT AND EARLY SATURDAY AS A SURFACE
FRONT BRIEFLY LINES UP WITH WEAK FORCING AT THE TAIL END OF THE
OREGON/WASHINGTON TROUGH.

SATURDAY, A MILD PACIFIC HIGH BUILDS INTO NEVADA AND NORTHEAST
CALIFORNIA. LIGHT NORTHEAST LOW LEVEL FLOW AND LOWER TEMPERATURES
ALOFT WILL BRING SLIGHTLY COOLER TEMPERATURES. I HAVE LEFT THE
SLIGHT CHANCE FOR SHOWERS NEAR THE SIERRA CREST SOUTH OF HIGHWAY
50 FOR A FEW HOURS SATURDAY EVENING FOR CONSISTENCY SAKE. HOWEVER,
ONLY THE GFS SHOWS ANY HINT OF PRECIPITATION SO IT MAY WIND UP JUST
BEING SCATTERED CUMULUS.

ON SUNDAY, WELL ABOVE AVERAGE SURFACE TEMPERATURES AND FAIRLY COOL
TEMPERATURES IN THE MID LEVELS MAY ALLOW FOR A BETTER SHOT AT A
FEW DIURNALLY-LINKED SHOWERS NEAR THE CREST OF MONO COUNTY.

SHOW VARYING DEGREES OF THIS ZONAL (WESTERLY) FLOW FOR TUESDAY
THROUGH THURSDAY WITH A SERIES OF SHORTWAVE TROUGHS MOVING INTO
THE PACIFIC NORTHWEST. GENERALLY THE ZONAL FLOW WILL RESULT IN
INCREASED CLOUD COVER AND WINDS NEXT WEEK. ALTHOUGH TEMPERATURES
WILL DROP WITH EACH SHORTWAVE THAT BRUSHES THE REGION, THEY ARE
STILL EXPECTED TO REMAIN ABOVE AVERAGE.

THE FIRST DISTINCT SHORTWAVE MOVES JUST NORTH OF THE REGION
TUESDAY MORNING WITH THE MAIN IMPACT BEING AN INCREASE IN NORTH
WINDS AND COOLER TEMPERATURES. A REINFORCING SHOT OF COOL AIR WILL
MOVE ACROSS THE REGION ON WEDNESDAY AS WELL, KEEPING TEMPERATURES
COOLER AND BREEZY NORTH WINDS ACROSS THE SIERRA AND WESTERN
NEVADA. BY THE END OF THE WEEK MODEL SOLUTIONS DIVERGE WITH THE
GFS BRINGING A TROUGH DOWN THE CALIFORNIA COAST WHILE THE ECMWF
DROPS THE TROUGH INTO THE GREAT BASIN. THE ECMWF SOLUTION WOULD
RESULT IN MUCH COLDER TEMPERATURES ACROSS THE REGION AS WELL AS
SOME CHANCE FOR PRECIPITATION. THE COLD FRONT WILL MOVE THROUGH
WITH 700MB TEMPERATURE VALUES IN THE -6 TO -10 DEGREES CELSIUS
RANGE. FORECASTER CONFIDENCE IS LOW WITH THIS TROUGH ON FRIDAY AS
MODELS HAVE VARIED SOLUTIONS AND RUN-TO-RUN DIFFERENCES. WEISHAHN

.AVIATION...

BUILDING RIDGE OF HIGH PRESSURE WILL RESULT IN LIGHT WINDS AND VFR
CONDITIONS THROUGH EARLY FRIDAY.

BREEZY CONDITIONS EXPECTED FRIDAY IN ADVANCE OF A WEAK COLD FRONT.
GUSTS IN THE 25-30 KT RANGE ARE FORECAST. RIDGE WINDS WILL
INCREASE THROUGH FRIDAY NIGHT AND TAPER OFF BY SATURDAY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
127 PM PDT THU MAR 26 2015

.SYNOPSIS...
AS HIGH PRESSURE SHIFTS EAST ON FRIDAY, BREEZY AND WARM CONDITIONS
WILL DEVELOP IN THE AFTERNOON WITH A FEW RECORD HIGH TEMPERATURES
LIKELY TO BE SET. WEAK LOW PRESSURE WILL BRING SLIGHTLY COOLER
TEMPERATURES FOR THE WEEKEND INTO EARLY NEXT WEEK ALTHOUGH HIGHS
WILL REMAIN ABOVE NORMAL.

&&

.SHORT TERM...
RIDGE AXIS WILL SHIFT EAST ON FRIDAY AS A TROUGH APPROACHES THE
WEST COAST. THIS WILL RESULT IN INCREASING SOUTHWEST WINDS AND
GOOD MIXING AS THERMAL TROUGH MOVES OVER WESTERN NV. WINDS WILL
GUST AS HIGH AS 30-35 MPH, ESPECIALLY FROM THE SIERRA FRONT
NORTHWARD WITH RIDGE WINDS INCREASING AND PEAKING FRI NIGHT WITH
TROUGH PASSAGE, GUSTING UP TO 60 MPH. TEMPERATURES WILL APPROACH
RECORD LEVELS AND EXCEED THEM IN A FEW LOCATIONS WITH LOWER 80S
FOR MANY WESTERN NV VALLEYS.

TROUGH WILL SPLIT AS IT MOVES INLAND WITH DECREASING WINDS AND A
GENERAL SHIFT IN SURFACE WINDS TO THE NORTH AND NORTHEAST THIS
WEEKEND. THIS WILL RESULT IN MOSTLY DRY AND SLIGHTLY COOLER
TEMPERATURES. THE GFS/NAM CONTINUE TO SHOW SOME WEAK INSTABILITY
NEAR CONVERGENCE ALONG THE SIERRA, AND LATER IN THE SEASON THIS
WOULD USUALLY RESULT IN SOME SHOWERS AND THUNDERSTORMS. WE
MAINTAINED A SLIGHT CHANCE OF SHOWERS DURING THE AFTERNOON AND
EARLY EVENING ALONG PARTS OF THE SIERRA ALTHOUGH CONFIDENCE IS
LOW. THE ECMWF SHOWS A DRIER NORTHWEST FLOW WITH NO INDICATION OF
CONVECTION. HOHMANN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
304 AM PDT THU MAR 26 2015

.SYNOPSIS...
HIGH PRESSURE WILL BRING VERY MILD AFTERNOON TEMPERATURES THROUGH
TOMORROW, WITH RECORD HIGH TEMPERATURES EXPECTED ON FRIDAY. WEAK
LOW PRESSURE WILL PUSH SLIGHTLY COOLER AIR INTO NORTHEAST CALIFORNIA
AND WESTERN NEVADA ON SATURDAY. VERY MILD TEMPERATURES RETURN EARLY
NEXT WEEK AS HIGH PRESSURE STRENGTHENS OVERHEAD.

&&

.SHORT TERM...
HIGH PRESSURE WILL BUILD DIRECTLY OVER CALIFORNIA AND WESTERN NEVADA
TODAY, BRINGING GENERALLY LIGHT WINDS OUTSIDE OF SOME MODEST EASTERLY
FLOW OVER THE SIERRA RIDGES THIS MORNING. WARMING ALOFT UNDER THE
RIDGE WILL MIX INTO THE VALLEYS TODAY FOR A 5-10 DEGREE WARM UP OVER
WEDNESDAY`S TEMPERATURES, WITH MID 60S TO MID 70S FOR VALLEYS.

ON FRIDAY, THE RIDGE AXIS PUSHES OFF INTO IDAHO AND EASTERN NEVADA
AS A TROUGH NEARS THE PACIFIC NORTHWEST COAST. THIS WILL INTENSIFY
THE THERMAL GRADIENT ACROSS THE REGION AS COOLER AIR INVADES NORTHERN
CALIFORNIA. THIS WILL MEAN AFTERNOON WINDS OF 10-20 MPH WITH GUSTS
30-35 MPH FOR THE SIERRA FRONT (RENO-CARSON CITY AREA) AND NORTHEAST
CALIFORNIA/NORTHWEST NEVADA. TEMPERATURES SHOULD EXCEED DAILY RECORDS
FOR A NUMBER OF SITES FRIDAY, INCLUDING RENO.

LATE FRIDAY NIGHT AND SATURDAY MORNING, THE DISTURBANCE WILL MOVE INTO
THE NORTHWEST CONUS WITH THE SOUTHERN EDGE OF THE TROUGH MOVING OVER
FAR NORTHERN CALIFORNIA AND NEVADA. THIS WILL PUSH A FRONT INTO THE
AREA FOR COOLER, BUT STILL WELL ABOVE AVERAGE TEMPERATURES. MODELS
HAVE REALLY ZEROED IN THIS SOLUTION IN THE PAST FEW RUNS SO CONFIDENCE
IS MUCH HIGHER FOR LITTLE OR NO PRECIPITATION (AND NO THUNDERSTORMS)
SATURDAY. SNYDER

.LONG TERM...SUNDAY THROUGH WEDNESDAY...
PRIMARY CHANGES MADE TO THE EXTENDED FORECAST THIS CYCLE WERE TO
ADJUST WINDS TO SHOW MORE PROGRESSION OF INDIVIDUAL UPPER WAVES AND
RESULTANT SURFACE TROUGHS AFTER MONDAY. MEDIUM RANGE DETERMINISTIC
MODELS ARE SHOWING A LITTLE BETTER RUN-TO-RUN CONSISTENCY TODAY...BUT
THERE REMAIN DIFFERENCES IN THE DETAILS.

ECMWF IS MOST PROGRESSIVE WITH TROUGH SUNDAY WHILE THE GFS AND GEM
SHOW A CLOSED LOW OVER SRN CA THAT IS NEVER COMPLETELY CUT OFF. THE
PRESENCE OF THIS LOW AND LOW-MID LEVEL INSTABILITY SUNDAY AFTERNOON
AND EVENING COULD PRODUCE ISOLATED SHOWERS OVER THE FAR SRN PORTIONS
OF THE FORECAST AREA. THE INSTABILITY MAY BE SUFFICIENT ENOUGH TO
PRODUCE TSTMS...BUT THESE WOULD BE VERY ISOLATED IN NATURE SO THEY
WERE NOT ADDED YET.

SHORT WAVE RIDGE BUILDS BRIEFLY FOR MONDAY WITH SLIGHTLY WARMER TEMPS
THAN SUNDAY...BUT THEN FLATTENS AND MOVES EAST. ALL DETERMINISTIC
MODELS SHOW A MORE ZONAL FLOW FOR TUESDAY AND WEDNESDAY WITH A
SERIES OF SHORT WAVE TROUGHS MOVING JUST NORTH OF THE FORECAST
AREA. THERE ARE HINTS THAT THE WAVE WEDNESDAY MAY DIP FAR ENOUGH
SOUTH TO PRODUCE SHOWERS ACROSS THE FAR NORTHERN CWA...BUT
CONFIDENCE IN THIS SOLUTION REMAINS LOW. OVERALL...THE ZONAL FLOW
MAY ACT TO JUST INCREASE CLOUDS AND WINDS TUESDAY AND WEDNESDAY
AND DROP TEMPS A BIT. THE EXTENT TO THIS DROP IN TEMPS IS HARD TO
QUANTIFY THIS FAR OUT...BUT HIGHS SHOULD REMAIN ABOVE AVERAGE EVEN
WITH A DIP. 20

&&

.AVIATION...
BUILDING RIDGE OF HIGH PRESSURE WILL RESULT IN LIGHT WINDS TODAY AND
VFR CONDITIONS. INITIALLY THOUGHT FREEZING FOG WOULD DEVELOP IN FOG
PRONE VALLEYS THIS MORNING...BUT THAT HAS NOT HAPPENED YET. STILL
THINK WE COULD GET FOG JUST BEFORE SUNRISE. WITH MORE DRYING TODAY,
FOG MAY NOT BE AN ISSUE TONIGHT.

WINDS INCREASE A BIT FOR FRIDAY WITH GUSTS IN THE 25-30 KT RANGE AT
THE SURFACE EAST OF THE SIERRA. RIDGE WINDS WILL ALSO BEGIN TO
INCREASE BUT FEW CLOUDS WILL DEVELOP UNTIL LATE IN THE DAY.

A WEAK SURFACE FRONT COUPLED WITH AN UPPER LEVEL TROUGH OF LOW
PRESSURE MAY BRING A FEW SHOWERS TO AREAS NORTH OF KSVE AND GERLACH
EARLY SATURDAY. 20
