Another Major Surge of Moisture into Mammoth today then Hose to Shift South into Southern Ca Monday into Wednesday…..more snow for Mammoth through Mid Week

Satellite imagery shows a strong short wave trof about 700mi west of the crest moving toward the Northern California coast. This system is associated with the cold vortex and northern branch of the upper jet . As it intersects with the fire hose coming  in from north of Hawaii, another excessive period of snowfall is expected over the Southern and Central Sierra today. AMSU PWV are once again near 1.5 inches. The OAK sounding showing saturation for much of the column and is -22within the dendritic growth zone.

Bishop reported heavy rain mid morning with some power outages report as well in both Mono and Inyo counties.

Today and into tonight will be the heaviest snowfall for Mammoth. As the latest storm moves in to the Sierra, precipitation will focus along the entire length of the Sierra. Up-slope conditions are ideal with 700-MB winds from the southwest in the range of 45 to 65Knots. Add dynamics and you have periods of 2 to 4 inches an hour snowfalls. Expect this extremely heavy snow falls through early evening……then the intensity should slowly decrease as the cold front moves south. 

Snow levels will be falling later today and into tonight behind the front. 

The heaviest precipitation shifts southward into Southern Ca Monday…however, plenty of snowfall is still likely for the Mono County Sierra early to middle of next week.


Another 7 to 9 feet is possible between 4:00am Sunday through Tuesday over the sierra crest. The Village at  of Mammoth could see another 2 to 3 feet by Midnight tonight .
