.SHORT TERM...
UPPER WAVE CURRENTLY OFF THE COAST OF OREGON FCST TO BARREL THROUGH
THE REGION LATE TOMORROW...BRINGING STRONG GUSTY WINDS AND CHCS FOR
PRECIP. RELATIVELY LOW SPREADS IN SREF DATA IMPROVE CONFIDENCE IN
LARGE SCALE PATTERN DURING THE SHORT TERM. WITHIN SW FLOW ALOFT
AHEAD OF FEATURE...MOISTURE/INSTABILITY WILL INCREASE ENOUGH IN A
SLIVER OF OUR E/SE COUNTIES FOR ISOLD -TSRA THROUGH THIS EVE. RADAR
ALREADY SHOWING SOME RETURNS OVER SW MINERAL COUNTY AS OF 21Z.
WINDS BEGIN TO INCREASE CONSIDERABLY OVERNIGHT WITH 700MB FLOW FCST
TO REACH 35-40KTS BY 12Z/TUE. HIGHER RIDGES SHOULD SEE A
CORRESPONDING INCREASE IN WIND GUSTS...POSSIBLY NEARING 50-60 MPH BY
TUES MORNING. WHILE VALLEYS WILL DECOUPLE TO A GOOD EXTENT...WINDS
WILL AT LEAST STAY IN THE 5-10 MPH RANGE OVERNIGHT. DAYTIME MIXING
WITHIN CONVECTIVE BOUNDARY LAYER WILL INCREASE GUSTS INTO THE 35-40
MPH RANGE OVER MOST OF THE CWA TUESDAY. THOUGH NOT HIGH ENOUGH TO
WARRANT A WIND ADVISORY WILL ISSUE A HAZ WX OUTLOOK TO MENTION
THREAT FOR STRONG WINDS. SPECIFIC LAKE WIND ADVISORIES WILL BE
POSTED FOR PYRAMID/TAHOE. GFS DOES SHOW A SMALL POCKET OF SLIGHTLY
ENHANCED STABILITY NEAR 650MB TUES MORNING OVER THE NW QUAD OF THE
CWA...WHICH COULD BE A HINT OF AN INVERSION FORMING JUST ABOVE MTN
TOP LEVEL. SHOULD THIS OCCUR...HIGHER WIND GUSTS ARE CERTAINLY
POSSIBLE.
REGARDING PRECIP CHCS...FORCING AND STEEPENING LAPSE RATES ASSOC
WITH PASSING WAVE WILL GENERATE SCT TSRA OVER PRIMARILY THE NRN 1/3
OF THE CWA TUES-TUES NIGHT. THERE IS A SMALL CHC OF SEEING SOME
ISOLD -TSRA OVER THE SE COUNTIES TUES AFTN...BUT MID LEVEL FLOW IS
STRONG ENOUGH TO QUICKLY PUSH ANY ACTIVITY EAST INTO CNTRL NV. DRIER
AND MORE STABLE AIR OVERSPREADS THE REGION WED...CONTINUING THE
COOLING TREND WHICH STARTED TUESDAY. SOME RESIDUAL INSTABILITY MAY
GENERATE ISOLD -SHRA WEDNESDAY OVER PERSHING AND CHURCHILL
COUNTIES...BUT FCST LIS FROM GFS/SREF ARE INSUFFICIENT FOR THUNDER.
WARMING TEMPS ON THURSDAY AS HEIGHTS RISE.
CS
.LONG TERM...FRIDAY THROUGH MONDAY...
WARM AND DRY CONDITIONS WILL PREVAIL INTO EARLY NEXT WEEK AS RIDGES
OFF THE WEST COAST AND OVER NRN MEXICO REMAIN IN PLACE...LEAVING ERN
CA-WRN NV IN AN AREA OF WEAK FLOW AND ABSENT OF SIGNIFICANT MOISTURE
OR DYNAMICS. DAYTIME HEATING SHOULD ALLOW FOR SOME PM CUMULUS TO
FORM MAINLY IN THE SOUTH ZONES THRU NEXT WEEKEND BUT STILL LOOKS
UNFAVORABLE FOR ANY TSTM DEVELOPMENT. TEMPS WILL REMAIN SEVERAL
DEGREES ABOVE NORMAL THRU MONDAY WITH MOST VALLEYS IN THE UPPER 80S
TO LOWER 90S...ALTHOUGH WEAK BACK DOOR TROF PASSAGE WITH LIGHT NE
SURFACE FLOW MAY BRING TEMPS DOWN SLIGHTLY ON SUNDAY. MJD

.AVIATION...
ISOLD TSTMS WITH BRIEF MVFR CONDS AND OUTFLOW GUSTS TO 35 KT PSBL
THRU 03Z TODAY EAST OF BRIDGEPORT-SCHURZ-FALLON LINE. OTHERWISE VFR
CONDITIONS THROUGH TUESDAY AFTERNOON WITH SOME MVFR IN ISOLD-SCT
SHRA/TSRA BY TUES EVENING NORTH OF I-80. INCREASING SW WINDS ON TUES
WITH FREQUENT GUSTS 30-35 KT AFT 17Z IN HIGHER ELEVATION CA
VALLEYS...AND AFT 19Z IN LOWER VALLEYS OF WRN NV-NERN CA. REDUCED
VSBY TO MVFR OR LOCAL IFR IN BLDU FOR W-CNTRL NV EAST OF
GERLACH-FERNLEY-DAYTON LINE TUES AFTERNOON. RIDGETOP GUSTS 50 KT OR
GREATER TONIGHT-TUES. MJD

.FIRE WEATHER...
A STRONG LOW EVIDENT ON SATELLITE OFF THE PAC NW COAST WILL MOVE
EAST ACROSS NRN CA AND NRN NV TUESDAY AND WEDNESDAY. RED FLAG
WARNINGS LOOK GOOD FOR THIS EVENING FOR 278/270/458/450. WINDS STILL
NEED TO COME UP IN SOME AREAS...BUT THEY SHOULD INCREASE THIS
EVENING BEFORE HUMIDITY GETS TOO HIGH. VALLEY GUSTS WILL DROP OFF
LATER THIS EVENING...HOWEVER MIDSLOPES AND HIGHER ELEVATIONS WILL
LIKELY SEE WINDS GUST ALL NIGHT LONG...ALTHOUGH HUMIDITY SHOULD
IMPROVE.
THE MAIN CONCERN IS TUESDAY. THE 700 MB FLOW AHEAD OF THE LOW
INCREASES OVERNIGHT TONIGHT TO 25-35 KTS...AND PERSISTS THROUGH
TUESDAY. WINDS WILL DIE DOWN BEHIND THE FRONTAL PASSAGE LATE
TUESDAY AFTERNOON OVER NRN ZONES AND TUESDAY EVENING FURTHER SOUTH.
THE SURFACE GRADIENT REALLY TIGHTENS ON TUESDAY AHEAD OF FRONT AND
WOULD THINK WIND GUSTS UP TO 40 MPH OR HIGHER ARE LIKELY ACROSS THE
AREA. HUMIDITY WILL BE THE MAIN QUESTION. FOR AREAS SOUTH OF
INTERSTATE 80 IN NEVADA HUMIDITY SHOULD REMAIN BELOW 15% FOR SURE.
OTHER AREAS FROM MONO COUNTY NORTH THROUGH ZONE 458 ARE MORE
QUESTIONABLE. BUT MY FEELING IS THAT THE STRONGER WINDS WILL
COUNTERACT ANY RH INCREASE EVEN TO 20% OR SO...SO CRITICAL FIRE
WEATHER IS STILL LIKELY...AND WATCH WAS UPGRADED TO A RED FLAG FOR
TUESDAY. OVER 458...HUMIDITY INCREASE MAY BE MORE SIGNIFICANT
ESPECIALLY WITH HOW FAST THE SYSTEM IS MOVING...BUT THERE WILL
DEFINITELY BE A SIGNIFICANT WIND SHIFT FROM SOUTHWEST TO NORTH AS
THE FRONT MOVES THROUGH LATE TUESDAY AFTERNOON...SO THAT WILL ALSO
ADD TO THE CRITICAL FIRE WEATHER THREAT. MID SHIFT WILL HAVE TO TAKE
A LOOK AT 458 AND MAKE A FINAL DECISION ON A WARNING OR DROP THE
WATCH. CONDITIONS WILL IMPROVE FROM NORTH TO SOUTH TUESDAY NIGHT AS
THE WINDS DECREASE AND COOLER TEMPERATURES QUICKLY MOVE INTO THE
AREA. BENINATO
