HAZARDOUS WIND CHILLS NEAR OR BELOW ZERO DEGREES FOR SIERRA

CHANCES FOR LIGHT SHOWERS, MAINLY NEAR THE SIERRA.
DISCUSSION
AS THE CUT-OFF LOW SWINGS TO OUR SOUTH, A DEEPENING TROUGH WILL
ENVELOPE THE CENTRAL U.S., WHICH IS OUR NEXT MAIN FEATURE IN THE
FORECAST. FOR TODAY, WE ARE IN BETWEEN THESE TWO FEATURES, WITH HIGH
CLOUDS ACROSS SOUTHERN MONO COUNTY ON THEIR WAY EASTWARD. TO OUR
NORTHEAST, THIS RETROGRADING FRONTAL BOUNDARY MAY KICK UP A FEW SNOW
SHOWERS ACROSS NORTHERN NEVADA, AS CLOUDS FILL SKIES OVER THE BASIN
AND RANGE. BREEZY NORTH TO NORTHEAST WINDS WILL BRING A COLDER AIR
MASS INTO VIEW FOR TOMORROW NIGHT INTO SATURDAY.
HIGH TEMPERATURES SATURDAY WILL BE AROUND 5-10 DEGREES COLDER THAN
TODAY, AND WITH THE GUSTY NORTH TO NORTHEAST WINDS, WILL FEEL
MUCH COLDER. IF YOUR PLANS FOR SATURDAY INVOLVE GETTING OUT INTO
SIERRA BACKCOUNTRY, BRING PLENTY OF WARM CLOTHING TO PREVENT
FROSTBITE OR HYPOTHERMIA. SATURDAY NIGHT THE COLD AIR WILL LINGER,
BEFORE SUNDAY SEES A BIT OF MODERATION IN OUR HIGH TEMPERATURES.
THE TROUGH THAT DUG SOUTH AND BROUGHT THE COLD AIR VIA THE POLAR
FRONT JET WILL MEANDER EAST, AND COUPLED WITH THAT LONG-GONE CUT-
OFF LOW AS A MOISTURE SOURCE, WILL BRING HEADACHES TO OUR FRIENDS
BACK EAST, ESPECIALLY ACROSS THE SOUTHEASTERN U.S.
ONCE THE TROUGH MOVES ALONG, HIGH PRESSURE RETURNS FOR NEXT WEEK,
BRINGING BACK THE LIGHT WINDS AND VALLEY INVERSIONS. THIS WILL USHER
IN A GRADUAL WARMING TREND, WITH MOSTLY DRY DAYS AHEAD. THE ONLY
EXCEPTION IS A SHORTWAVE THAT WILL BRING LOW CHANCES FOR SHOWERS TO
NORTHEASTERN CALIFORNIA AND SOME PORTIONS OF NORTHWESTERN NEVADA
WEDNESDAY-THURSDAY. FOR NOW, CHANCES RANGE 10-20%, BUT AMOUNTS
LOOK LIGHT TO NEARLY NOTHING, SO SHOWERS MAY BE MORE OF A NUISANCE
THAN CAUSING ACCUMULATIONS. HRICH
AVIATION
* NORTH TO NORTHEAST WINDS TODAY, WITH GUSTS TO 25 KTS ACROSS
RIDGES NEAR THE TAHOE BASIN. BESIDES PATCHY MORNING FOG NEAR
KTRK, EXPECT VFR CONDITIONS FOR ALL TERMINALS TODAY.
* TONIGHT, A BAND OF LOW CLOUDS MAY BRING MVFR CIGS TO SIERRA
TERMINALS AND MOUNTAIN OBSCURATIONS NEAR WESTERN NV TERMINALS.
WIND GUSTS WILL ALSO INCREASE FOR WESTERN NEVADA TERMINALS
TONIGHT, WITH WINDS PEAKING SATURDAY. NORTHERN TO NORTHEASTERLY
GUSTS WILL APPROACH 45-50 KTS ACROSS SIERRA RIDGES LATE SATURDAY
INTO SUNDAY MORNING. TURBULENCE AND LLWS MAY BECOME ISSUES LATE
SATURDAY INTO SUNDAY, PARTICULARLY ALONG THE WESTERN SLOPES OF
THE SIERRA. HRICH
