Well, we’re about 1/2 way through this deluge, and the atmospheric river is nailing Tahoe. Mixed/wet in town, but above 7,000/7,500 it is nuking. Squaw is calling for 6 feet up high come Monday. Already great coverage up high, and this system will really set us up … now we need some cold ones to come in and help with access and the lower el. Skiing is great up high right now, stormy as all get-out, but skiing really nicely. Avy danger is pegged. Heads up if you venture out. Monday and early next week we should be in for some stellar exploration.
FRIDAY NIGHT AND SATURDAY, WE`LL SEE A LULL IN THE ACTION AS WE WILL BE IN BETWEEN WEATHER SYSTEMS. OROGRAPHIC LIFT AND MOISTURE WILL CONTINUE LIGHT RAIN/SNOW INTO THE SIERRA THROUGH SATURDAY, BEFORE THE NEXT WAVE MOVES IN SATURDAY NIGHT.
AS WE GO INTO SATURDAY NIGHT AND SUNDAY, THE STRONGEST STORM OF THE SERIES WILL PUSH INTO THE WEST COAST. WINDS WILL INCREASE AGAIN IN
THE SIERRA AND INTO WESTERN NEVADA, WITH A POWERFUL DOWNSLOPE WIND SIGNATURE EVIDENT ON LATEST NAM MODEL RUNS WITH AN IMPRESSIVE 80KT
“FOOT” EXTENDING WELL OUT INTO THE FERNLEY-SILVER SPRINGS-FALLON AREA. DIDN`T ISSUE ANYTHING JUST YET ASSOCIATED WITH THESE WINDS, AS
WE ARE CURRENTLY UNDER A WIND EVENT RIGHT NOW. WE WILL LIKELY NEED TO CONSIDER WIND STATEMENTS FOR SATURDAY NIGHT INTO SUNDAY ON FUTURE
SHIFTS. STRONG WINDS ARE EXPECTED THROUGHOUT THE ENTIRE WEEKEND, BUT THAT PERIOD LATE SATURDAY NIGHT AND EARLY SUNDAY REALLY LOOKS IMPRESSIVE, WITH GUSTS EVEN STRONGER THAN WHAT WE ARE SEEING CURRENTLY.
STRONG ISENTROPIC LIFT IN THE WARM CONVEYOR BELT WITH PWATS NEAR 1.5″ OFF-SHORE WILL MOVE INTO THE REGION PRODUCING HEAVY RAINFALL.
SNOW LEVELS ARE EXPECTED TO RISE ABOVE 8000 FEET SATURDAY NIGHT, AND THEN CLOSE TO 10000 FEET BY SUNDAY MORNING. THIS WILL BRING HEAVY
RAINFALL TO THE SIERRA AND INTO WESTERN NEVADA, CAUSING SHARP RISES IN AREA STREAMS AND RIVERS. SEE HYDROLOGY SECTION BELOW FOR DETAILS.
COLD FRONT WILL PASS THROUGH THE AREA SUNDAY AFTERNOON AND EVENING, BRINGING SNOW LEVELS DOWN TO NEAR 6000 FEET. TIMING OF THE COLD
FRONT HAS SLOWED DOWN A BIT, SO ITS POSSIBLE THAT THE SNOW LEVELS MAY NOT DROP UNTIL THE EVENING. BY THIS TIME, THE BULK OF THE PRECIP
WILL BE DEPARTING THE AREA, WITH ONLY A BRIEF WINDOW IN THE EVENING OF SNOW DOWN TO 6000-7000 FEET. ANY SIGNIFICANT SNOW AMOUNTS WILL LIKELY BE LIMITED TO ELEVATIONS ABOVE 7000 FEET.
