Using 5F decrease for every 1000 feet above 7000 feet will put you for snow 7000-8000 feet and above.
Would be more comfortable saying above 8000 feet for snow since daytime highs for all week is projected to be over 40F.
mammoth @6400 feet is forecasted to have warmer temps by a few degrees than Truckee for the same time period.
Mammoth Forecast 8 FEB SAT 930 PST
Sat 9:50pm
Mammoth Pass reports 1.22 inches of precipitation so far and less than Yosemite. Temperature at 8200ft is 36 degrees, while at the main lodge it is 30. Snow level about 8400. Main Plume is nearing the north coast now and will be moving in shortly over the north coast. Precip rates will pick up after midnight tonight with another inch and a half of QPF expected. Snow levels are verifying a little lower than forecast…..so it is now possible that some 3 to 5 inches may fall over the next 24 hours at elevations above 8000 feet by Sunday Afternoon.
After this storm…. the storm door closes except for a few minor systems. Both 6 to 10 and 8 to 14 outlooks look drier then normal….
Next update in the morning……
