NORTHERN SIERRA TODAY. EXPECT GUSTY WINDS FOR W.NEVADA THIS
AFTERNOON WITH LIGHT RAIN AND SNOW SHOWERS THIS EVENING.

DISCUSSION
A FAST MOVING LOW PRESSURE SYSTEM WILL PROVIDE A ROUND OF LIGHT
SNOW SHOWERS ACROSS THE NORTHERN SIERRA TODAY ALONG WITH GUSTY
SOUTHWEST WINDS ACROSS WESTERN NEVADA TODAY. THE MAIN WAVE OF
SNOW SHOWERS LOOKS TO MOVE ALONG THE N.SIERRA CREST AFTER 1-2P
THIS AFTERNOON WITH SNOW LEVELS AROUND 5500-6000'.
SNOW ACCUMULATIONS ARE LOOKING SPOTTY DUE TO THE CONVECTIVE
NATURE OF THE SNOW ALONG THE INCOMING COLD FRONT. OVERALL THE
SIERRA CREST PASSES LOOK TO BE THE BEST CANDIDATES TO RECEIVE UP
TO 1-2" OF SNOW ACCUMULATIONS FROM MID-AFTERNOON INTO EARLY
EVENING WITH TRACE AMOUNTS OF SNOW POSSIBLE DOWN TO LAKE LEVEL.
SNOW SHOWERS WILL BE CONFINED MAINLY TO US-50 NORTHWARD WITH
LITTLE TO NO SNOW CHANCES FOR ALPINE AND MONO COUNTIES. IMPACTS TO
AREA ROADS WILL BE LIMITED TO BRIEF PERIODS OF SLUSH ACROSS THE
HIGHER PASSES SHOULD A HEAVIER SHOWER OCCUR.
WESTERN NEVADA VALLEYS COULD SEE A BRIEF WINDOW BETWEEN AROUND
7-11P THIS EVENING WHERE A SMALL BAND OF RAIN AND SNOW SHOWERS
MOVE THROUGH WITH THE COLD FRONT. SNOW LEVELS AROUND 5000-5500
FEET DURING THIS TIME FRAME COULD PROVIDE TRACE AMOUNTS OF SNOW
ACROSS WESTERN NEVADA FOOTHILLS WITH SLICK CONDITIONS POSSIBLE
OVERNIGHT AS TEMPERATURES DIP BELOW FREEZING.
OVERALL WINDS WILL BE THE MAIN IMPACT WEDNESDAY WITH AFTERNOON
WIND GUSTS EXPECTED TO REACH AROUND 30-40 MPH FOR MOST AREAS AS
SIERRA RIDGETOP GUSTS EXCEED 80 MPH. THIS WILL RESULT IN CHOPPY
LAKE WATERS AND AVIATION TURBULENCE. STRONG CROSSWINDS FOR HIGH
PROFILE VEHICLES CAN BE EXPECTED ALONG HWY 395/I-580 WITH THESE
GUSTY WINDS PUSHING OUT INTO THE BASIN AND RANGE DURING THE
AFTERNOON, IMPACTING AREA HIGHWAYS INCLUDING HWY 95 NEAR WALKER
LAKE. SURFACE WINDS SHOULD BEGIN TO WEAKEN AS THE SUN SETS, BUT
WINDS WILL STAY BREEZY ACROSS THE RIDGES AS THEY SHIFT TO THE NE
LATE WEDNESDAY NIGHT INTO THURSDAY.
MOST SHOWER ACTIVITY WILL DIMINISH BY WEDNESDAY EVENING WITH HIGH
PRESSURE THEN BUILDING IN FOR THE REMAINDER OF THE WEEK. TEMPERATURES
WILL HANG AROUND AVERAGE VALUES THROUGH FRIDAY BEFORE WARMING TO
NEAR MID-APRIL VALUES BY LATE WEEKEND INTO EARLY NEXT WEEK. EXPECT
HIGHS TO REACH INTO THE LOW TO MID-60S ACROSS WESTERN NEVADA WITH
MID TO UPPER 50S FOR SIERRA COMMUNITIES. FUENTES
AVIATION
* FAST MOVING COLD FRONT TO MOVE THROUGH THIS AFTERNOON/EVENING.
THERE IS A 30-50% CHANCE OF -SHRA/-SHSN BETWEEN 21-06Z AT
KTRK/KTVL WITH SNOW ACCUMULATION UNLIKELY. OTHER TERMINALS TO
REMAIN DRY EXCEPT FOR MAYBE A FEW LIGHT SHOWERS REACHING KRNO-
KCXP-KMEV IN THE EVENING (03-07Z).
* W-SW WINDS WILL INCREASE OVER THE RIDGES BEGINNING AROUND 12Z,
PEAKING 18-21Z AROUND 45-50 KTS AND THEN TURNING WSW AS THE
TROUGH SWINGS THROUGH THE AREA DURING MID TO LATE AFTERNOON.
EXPECT MODERATE TO LOCALLY SEVERE TURBULENCE, ESPECIALLY FOR
SMALLER AIRCRAFT. LLWS AND ROTORS CAN ALSO BE EXPECTED WITH W-SW
SURFACE WINDS OF 15-25 KTS WITH GUSTS 30-35 KTS. HOHMANN/FUENTES
