DISCUSSION
FOLLOWING A BUSY START TO FEBRUARY, THE WEEK AHEAD LOOKS
RELATIVELY CALMER, THOUGH A QUICK MOVING, WEAKER STORM SYSTEM WILL
MOVE ACROSS THE SIERRA ON WEDNESDAY. EXPECT A FEW INCHES OF SNOW
FOR SIERRA PASSES, POSSIBLY CAUSING TRAVEL SLOW DOWNS FOR TRANS-
SIERRA TRAVEL. HIGH PRESSURE THEN BUILDS AND COULD YIELD OUR FIRST
SPRING-LIKE WARM-UP BY LATE WEEKEND AND INTO EARLY NEXT WEEK.
SEASONABLE TEMPERATURES WITH DRY CONDITIONS WILL PREVAIL TODAY
ASIDE FROM A FEW LIGHT SNOW SHOWERS NEAR THE OREGON BORDER. GUSTY
WIND ACROSS THE SIERRA RIDGETOPS WILL STEADILY SUBSIDE THROUGH THE
AFTERNOON WITH LIGHT WEST BREEZES FOR LOWER VALLEYS.
A QUICK HITTING STORM SYSTEM MOVING IN LATE WEDNESDAY MORNING
COULD YIELD LIGHT SNOW ACCUMULATIONS OF 2-3" ALONG TAHOE BASIN
PASSES THROUGH WEDNESDAY EVENING. AREAS FURTHER SOUTH THROUGH
ALPINE AND MONO COUNTY ARE LOOKING AT LESSER POTENTIAL WITH AROUND
AN INCH POSSIBLE. SNOW LEVELS LOOK TO START AROUND 6000-6500 FEET
BEFORE LOWERING TO NEAR 5500 FEET IN THE EVENING. A FEW LIGHT
RAIN OR SNOW FLURRIES ARE POSSIBLE (20% CHANCE) ACROSS WESTERN
NEVADA VALLEYS. WINDS MAY BE MORE OF A FACTOR FOR LOWER VALLEYS
WITH GUSTS OF 30-40 MPH WITH SIERRA GUSTS REACHING 80+ MPH.
MOST PRECIPITATION WILL MOVE OUT OF THE AREA BY WEDNESDAY EVENING
WITH HIGH PRESSURE BUILDING IN BEHIND FOR THE REMAINDER OF THE
WEEK. THIS WILL PROVIDE DRY CONDITIONS, LIGHT WINDS, AND THE
DEVELOPMENT OF VALLEY INVERSIONS. TEMPERATURES WILL REMAIN
SEASONABLE THROUGH FRIDAY BEFORE TEMPERATURES WARM TO SPRING-LIKE
VALUES THIS WEEKEND INTO EARLY NEXT WEEK WHICH HIGHS REACHING INTO
THE LOWER 60S ACROSS WESTERN NEVADA VALLEYS. FUENTES
AVIATION
AREAS OF MOUNTAIN WAVE TURBULENCE AND LLWS WILL CONTINUE THIS
MORNING AS SIERRA RIDGE TOP (FL100) WIND GUSTS REACH 50-60 KT.
RIDGETOP WINDS WILL EASE THROUGH THE DAY WITH LLWS AND MOUNTAIN
WAVE TURBULENCE WEAKENING AFTER 19-20Z.
OTHERWISE, VFR CONDITIONS WILL PREVAIL ACROSS THE REGION THROUGH
TUESDAY AHEAD OF THE NEXT INCOMING WEAKER SIERRA STORM SYSTEM ON
WEDNESDAY. THIS SYSTEM IS EXPECTED TO PRODUCE INCREASING MOUNTAIN
WAVE TURBULENCE AND LLWS. MOST OF THE PRECIP (RAIN/SNOW MIX) IS
EXPECTED TO BE LIMITED TO KTRK-KTVL BETWEEN 19-04Z. KTRK AND KTVL
COULD SEE A 15% CHANCE OF AN INCH OF SNOWFALL WITH ACCUMULATIONS
UNLIKELY FOR KMMH AND WESTERN NEVADA TERMINALS. FUENTES
