DISCUSSION
MILD AND DRY WEATHER WILL SETTLE IN BEHIND YESTERDAY'S PASSING
LOW PRESSURE SYSTEM. MOSTLY CLEAR CONDITIONS WITH LIGHT WINDS
WILL PREVAIL THIS AFTERNOON AS HIGH TEMPERATURES RETURN TO NEAR 70
DEGREES ACROSS W.NEVADA WITH 60S FOR SIERRA VALLEYS.
FRIDAY WILL BE OUR LAST MILD DAY OF THE WEEK AS WESTERN NEVADA
VALLEYS WARM INTO THE MID-70S WHILE SOUTHWESTERLY BREEZES BEGIN
TO PICKUP AHEAD OF OUR INCOMING WEEKEND STORM SYSTEM. BREEZIEST
CONDITIONS ARE EXPECTED ROUGHLY NORTH OF SUSANVILE-PYRAMID LAKE
WHERE AFTERNOON GUSTS COULD REACH 25-30 MPH.
THIS WEEKEND:
* A COLDER, WINDIER, AND WETTER PATTERN IS FAVORED THIS WEEKEND AS
WE GET CLIPPED BY THE SOUTHERN END OF AN ATMOSPHERIC RIVER STORM
THAT WILL MOVE THROUGH THE PACIFIC NORTHWEST.
* SATURDAY CONTINUES TO BE THE FOCUS FOR GUSTY WINDS AND RAINFALL.
WIND LOOKS TO BE THE MOST WIDESPREAD IMPACT SATURDAY AFTERNOON,
PARTICULARLY FOR AREAS NORTHWARD OF US-50 AND ALONG THE
US-395/I580 CORRIDOR. WIDESPREAD GUSTS OF 35-45 MPH ARE EXPECTED
WITH AREAS IN N.LASSEN AND N.WASHOE COUNTIES SEEING 25% ODDS OF
SEEING GUSTS EXCEED 50 MPH. SIERRA RIDGETOPS GUSTS ARE EXPECTED
TO EXCEED 100 MPH. EXPECT IMPACTS FOR OUTDOOR RECREATION,
AVIATION, AND CROSS WIND HAZARDS FOR HIGH PROFILE VEHICLES.
* AS THIS SYSTEM HAS TRENDED NORTHWARD OVER THE LAST SEVERAL DAYS,
WE'VE SEEN A SUBSEQUENT DOWNWARD TREND IN RAIN AND MOUNTAIN SNOW
POTENTIAL. MOST ELEVATIONS ARE TRENDING TOWARDS MAINLY A RAIN
EVENT WITH 0.33-0.75" OF RAINFALL FROM THE TAHOE BASIN INTO
LASSEN COUNTY. SPILLOVER RAINFALL INTO FAR WESTERN NEVADA IS
BECOMING INCREASINGLY SHADOWED WITH 0.05-0.10" RAINFALL RANGE
WITH SIMILAR AMOUNTS FOR MOST OF MONO COUNTY. SNOWFALL POTENTIAL
HAS ALSO BECOME LIMITED WITH A 30% CHANCE OF UP TO 2 INCHES ON
SIERRA PASSES ABOVE 8000 FEET.
* BY SUNDAY, TEMPERATURES WILL BE AROUND 10-15 DEGREES BELOW
AVERAGE, WITH MOSTLY 50S IN WESTERN NV AND LOW-MID 40S FOR THE
EASTERN SIERRA. WE'LL START A SLOW WARMING TREND MONDAY THROUGH
THE MIDDLE OF NEXT WEEK WITH DRIER WEATHER. FUENTES
