DISCUSSION
AN UPPER LOW PASSAGE WILL DELIVER GUSTY WINDS, AND A LOW CHANCE OF
RAIN AND THUNDERSTORMS TODAY INTO THURSDAY. S/SW GUSTS INCREASE TO
25-35 MPH THIS AFTERNOON FROM THE TAHOE-RENO AREA SOUTH TO MONO
AND MINERAL COUNTIES. LOCALLY STRONGER GUSTS OF 40-45 MPH REMAIN
POSSIBLE IN WIND PRONE AREAS SUCH AS I-580 NEAR WASHOE LAKE AND
US-395 BETWEEN MONO LAKE AND MAMMOTH. AS SUCH, PLAN ON GUSTY
CROSSWINDS AND MORE DIFFICULT DRIVING CONDITIONS ALONG US-395
BETWEEN RENO AND MAMMOTH, ESPECIALLY ALONG THOSE WINDIER
STRETCHES. GUSTY WINDS WILL ALSO MAKE FOR ROUGHER LAKE WATERS AND
A FEW HOURS OF LOCALIZED NEAR-CRITICAL FIRE WEATHER CONDITIONS
FROM THE SIERRA FRONT INTO MONO AND MINERAL COUNTIES TODAY.
MEANWHILE, WIND GUSTS ALONG THE SIERRA CREST WILL INCREASE FROM
45-50 MPH IN THE AFTERNOON TO NEAR 60 MPH OVERNIGHT INTO THURSDAY
MORNING. EXPECT BUMPY FLIGHTS OVER THE SIERRA AND A CHILLY
THURSDAY MORNING FOR HIGHER SIERRA ELEVATIONS. WINDS REMAIN BREEZY
THURSDAY, BUT MORE TYPICALLY SO WITH GUSTS OF 20-30 MPH IN THE
AFTERNOON.
FARTHER NORTH, RAIN CHANCES INCREASE TO 10-20% THIS AFTERNOON
ACROSS PORTIONS OF LASSEN COUNTY INTO THE SURPRISE VALLEY AND FAR
N WASHOE COUNTY. WEAK INSTABILITY AND MOISTURE WILL ALSO SUPPORT
A 10-15% CHANCE OF THUNDERSTORMS IN THE AFTERNOON. A FEW OF THE
MORE AGGRESSIVE SOLUTIONS DEPICT A NARROW BAND OF RAIN WITH
POSSIBLY EMBEDDED LIGHTNING DEVELOPING FROM LASSEN COUNTY INTO
NORTHERN WASHOE COUNTY EARLY THURSDAY MORNING. HOWEVER, THIS SEEMS
MORE LIKE AN OUTLIER SCENARIO WITH ONLY A 10-15% CHANCE OF
MATERIALIZING. RAIN AND THUNDERSTORM CHANCES INCREASE TO 20-30%
THURSDAY AFTERNOON, BUT REMAIN CONFINED NEAR THE OREGON BORDER.
AFTER A COUPLE DAYS OF COOLER THAN NORMAL WEATHER, A WARMING TREND
WILL BRING TEMPERATURES BACK TO SEASONAL AVERAGES BY THE WEEKEND
WITH MID-70S TO MID-80S DAYTIME HIGHS. THE ONLY OTHER NOTABLE
ITEM IS A DRY FRONTAL PASSAGE FRIDAY THAT ENCOURAGES BREEZY E-NE
WINDS ALONG AND WEST OF THE SIERRA CREST FRIDAY NIGHT INTO
SATURDAY MORNING. OTHERWISE, THIS WEEKEND IS TRENDING TOWARDS
BEING A WARM AND DRY ONE. ENSEMBLES CONTINUE TO HINT AT INCREASING
WINDS AND RAIN CHANCES EARLY NEXT WEEK, PARTICULARLY FOR AREAS
SOUTH OF TAHOE/RENO.
-SALAS
AVIATION
SURFACE WINDS INCREASE THIS AFTERNOON FOR ALL TERMINALS, WITH
INITIAL S-SW GUSTS REACHING 20-25 KTS AT KTRK-KTVL AND 25-30 KTS AT
KRNO-KCXP-KMEV. WINDS ARE EXPECTED TO SHIFT TO WESTERLY AT KRNO-
KCXP-KMEV BETWEEN 00-03Z THIS EVENING. STRONGER SW GUSTS OF 30-35
KTS ARE FAVORED AT KMMH THIS AFTERNOON. S/SW FL100 WINDS INCREASE
TO 35 KTS AFTER 03Z, INCREASING LLWS AND MOUNTAIN WAVE TURBULENCE
CONCERNS IN THE SIERRA.
