DISCUSSION
HOLD ON TO YOUR HATS; IT'S BLUSTERY OUT THERE TODAY! AN
ATMOSPHERIC RIVER BRINGING RAIN TO THE PACNW IS BRINGING LIGHT
SHOWERS ACROSS THE SIERRA AND GUSTY TO STRONG WINDS ACROSS MUCH OF
W NV AND THE SIERRA FRONT TODAY. CURRENT OBSERVATIONS HAVE GUSTS
UPWARDS OF 80 MPH ALONG RIDGETOPS, NEAR 70 MPH FOR WIND PRONE
LOCATIONS, AND 40-50 MPH FOR VALLEY LOCATIONS. EXPECT WINDY
CONDITIONS TO CONTINUE THROUGH TODAY AS THE 700 MB JET INTENSIFIES
OVER OUR AREA THIS AFTERNOON. BUMPY FLIGHTS, CHOPPY LAKE WATERS,
BLOWING DUST, AND DIFFICULT TRAVEL ARE ALL EXPECTED TODAY; EXHIBIT
CAUTION WHILE DRIVING ALONG WIND-PRONE LOCATIONS TODAY.
SPILLOVER SHOWERS INTO W NV AND MONO COUNTY WILL BE LIMITED
TODAY, WHILE LOCATIONS ACROSS THE TAHOE BASIN CAN EXPECT LIQUID
ACCUMULATIONS OF 0.3-0.8" THROUGH TOMORROW AFTERNOON. SHOWERS WILL
TAPER OFF AFTER SUNSET TONIGHT BUT A SECOND ROUND CAN BE EXPECTED
TO START FOR THE TAHOE BASIN BY SUNRISE TOMORROW. LOCATIONS IN NE
CA AND FAR NW WASHOE COUNTY WILL SEE SHOWERS RETURN AFTER
MIDNIGHT TONIGHT. CURRENT SNOW LEVELS ARE AROUND 9 KFT, BUT WILL
LOWER TO 7 KFT BY EARLY TOMORROW MORNING. SNOW RATIOS ARE QUITE
LOW; ~5:1, MEANING ANY SNOWFALL ACCUMULATIONS WILL BE SLUSHY IN
NATURE. HIGHEST SNOWFALL TOTALS (2-3") WILL BE SEEN ALONG THE
TALLEST PEAKS IN THE TAHOE BASIN FROM THIS SYSTEM.
GUSTY TO STRONG WINDS CAN BE EXPECTED ACROSS MUCH OF THE AREA
SOUTH OF I-80 TOMORROW. AMPLIFICATION OF THE 250 MB JET OVER OUR
AREA IS EXPECTED TOMORROW AFTERNOON; THIS WILL BRING SIMILAR
GUSTS OF 40-50 MPH, NEAR 70 MPH FOR WIND-PRONE LOCATIONS, AND 100
MPH FOR RIDGETOPS. AS SUCH, A SECOND WIND ADVISORY IS IN EFFECT
FROM 11 AM THROUGH 11 PM TOMORROW. SUNDAY WILL ALSO BE THE COLDEST
DAY OF THE WEEK, WITH HIGHS IN THE UPPER 50S TO LOW 60S FOR VALLEY
LOCATIONS AND UPPER 40S FOR SIERRA COMMUNITIES.
A RIDGING PATTERN RETURNS MONDAY; THIS WILL IGNITE A DRYING AND WARMING
TREND THROUGH THE MAJORITY OF THE WEEK TO CLOSE OUT OCTOBER.
