Friday 8:00 AM Update


The only change in the forecast from below is that the Freezing level is now forecasted to begin lower in the Mammoth Area. At Yosemite, 8,400 feet at 4:00 AM but drops to 6100 by 10:00 am. The snow level is typically 1000 to 1500 feet lower than the freezing level.  Thus this storm will be all snow from beginning to end for the Town of Mammoth Lakes. Light amounts are still predicted; 2 to 4 inches by Monday AM… with 4 to 8 inches over Mammoth Mt.  It will be exceptionally windy Saturday night and Sunday.

A continuation of mild weather is likely through Saturday with windy conditions developing Saturday afternoon into the night. Highs will be in the 40s Friday and Saturday with lows in the teens and 20s. The next pattern change, appears to be one of a fragmentation of the jet stream.  The upper jet is split and fragmented in several places. Additionally, the upper flow associated with the point in time of precipitation is southerly. This all adds up to a pretty wimpy storm. Snowfall estimates are not anything special with 4 to 8 inches possible on the mountain Sunday into Monday AM and 2 to 4 inches in town the same period. The Freezing level will be about 9000 Sunday morning into Early afternoon which would suggest a snow level of about 7500 feet in Mammoth. The snow level will lower through out the day and night, so lower elevations along 395 will have the possibility of a few inches of snow as well by morning.


Once this cold trough sets up, it will be cold with periods of snow showers through Christmas day….  In this point in time, the Dweebs do not see a major storm on the horizon yet….


High temps next week will be in the low to mid 20s with lows in the single digits and teens…………..
