DISCUSSION
TODAY WILL BE THE WARMEST DAY OF THE WEEK AS TEMPERATURES PEAK IN
THE UPPER 60S TO MID 70S THIS AFTERNOON. IN FACT, SOME LOCALES MAY
EVEN SEE RECORD-BREAKING HIGHS TODAY, INCLUDING RENO AND SOUTH LAKE
TAHOE WHERE TODAY'S FORECAST/RECORD HIGH IS 74/74 AND 68/69,
RESPECTIVELY. MINOR COOLING IS EXPECTED AFTER TODAY, BUT WARM AND
DRY WEATHER CONTINUES UNTIL WEDNESDAY WITH HIGH PRESSURE OVERHEAD.
POTENT LOW PRESSURE AND ATTENDANT COLD FRONT REMAIN ON TRACK TO
BRING PERIODS OF STRONG WINDS, VALLEY RAIN, AND MOUNTAIN SNOW LATE
WEDNESDAY INTO FRIDAY. WINDS BEGIN TO INCREASE WEDNESDAY AFTERNOON
WITH SW/W GUSTS OF 25-35 MPH LIKELY INDUCING MINOR IMPACTS TO FIRE
(MORE DETAILS IN THE FIRE WEATHER DISCUSSION) TRAVEL AND RECREATION.
UNLIKE OUR TYPICAL WINDY DAYS, WINDS WILL FURTHER INTENSIFY DURING
THE OVERNIGHT HOURS IN RESPONSE TO THE APPROACHING COLD FRONT AND
PEAK SOMETIME THURSDAY MORNING AS THE FRONT ADVANCES THROUGH THE
REGION. PRELIMINARY EXPECTATIONS ARE FOR S/SW GUSTS OF 40-50 MPH IN
SIERRA VALLEYS AND SIERRA FRONT BETWEEN 4 AM AND 10 AM PST THURSDAY
WITH WIND PRONE LOCALES FLIRTING WITH 60 MPH GUSTS. MEANWHILE,
COMMUNITIES IN THE W NV BASIN AND RANGE LIKELY SEE STRONGEST GUSTS
OF 30-40 MPH IN THE 10 AM TO 2 PM PST WINDOW. BE PREPARED FOR BUMPY
FLIGHTS, CHOPPY LAKES, AND DIFFICULT DRIVING CONDITIONS FOR HIGH-
PROFILE VEHICLES THURSDAY MORNING -- ESPECIALLY ALONG I-80 AND US-50
WHERE CROSSWIND HAZARDS ARE MOST LIKELY.
WINDS WILL LIKELY REMAIN BREEZY THROUGH THE AFTERNOON THURSDAY, BUT
SHOULD WEAKEN AFTER THE FRONT PASSES AND RAIN/SNOW MOVES IN. WHILE A
FEW SHOWERS MAY DEVELOP IN THE SIERRA AS EARLY AS WEDNESDAY EVENING,
SIERRA SNOWFALL BEGINS IN EARNEST THURSDAY MORNING IN CONCERT WITH
THE COLD FRONTAL PASSAGE. SNOW LEVELS CONTINUE TO BE TRICKY WITH
THIS STORM -- ESPECIALLY WITH THE POTENTIAL FOR A HEAVIER BAND OF
PRECIP -- BUT SHOULD BE LOW ENOUGH TO ALLOW SNOWFALL (60-90% CHANCE
OF 6+" OF SNOW BY FRIDAY AM) ALONG SIERRA PASSES, LIKELY RESULTING
IN TRAVEL DISRUPTIONS THURSDAY. THE MAIN TAKEAWAY, GETTING YOUR
TRAVELING DONE BEFORE THURSDAY, OR BE PREPARED FOR SLICK ROADS AND
DELAYS IF YOU MUST TRAVEL. SNOW LEVELS CONTINUE TO FALL
TOWARDS/BELOW LAKE LEVEL IN THE WAKE OF THE COLD FRONT, BUT RAIN AND
SNOW BECOMES MORE SHOWERY IN NATURE. FARTHER EAST, SHADOWING WILL
LIKELY KEEP WESTERN NEVADA DRY INITIALLY BEFORE RAIN FINALLY SPILLS
OVER THURSDAY AM ONCE THE FRONT ARRIVES. A FEW SHOWERS WILL LIKELY
LINGER INTO FRIDAY, BUT WE'LL BEGIN TO DRY OUT AS WE HEAD INTO THE
WEEKEND. TEMPERATURES BE MUCH COOLER THURSDAY ONWARD WITH CHILLY
NIGHTTIME CONDITIONS.
