Winds will be on the increase today Thursday as a splitting trof approached the west coast. A few showers are possible over Mono County. However, the southern portion of the county is not expected to experience anything measurable. Winds will be the main theme with Southwest gusts increasing to 95 mph over the crest, while winds in the residential areas could reach 50 mph. A wind advisory is now hoisted for the county.
New 12z nam/wrf shows a splitting trof off shore with the main baroclinic band over Northern Ca. Topo lift will allow for some showers for Mono County by late afternoon. The freezing level over Mammoth is 10K today….9.5K Friday and 8.5K Saturday. Snow levels generally are some 1500 feet to 2000 feet below this level. The heaviest precip will be on the west side, Tahoe north today. Highs in Mamoth today will be in the 40s vs. low 50s yesterday.
A baroclinic band will weaken somewhat Saturday as the splitting process continues. There after…a double structured baroclinic band develops Saturday afternoon with one band mainly north of Tahoe with the other over the Southern Sierra. CRFC gives Yosemite a QPF of .1 Friday and .2 for Saturday.
At 10:1 possibly an inch of snow Friday for Mammoth Mountain and 2 inches Saturday.
The temp should pick up Sunday as the southern branch and main closed/cut off low gets the boot inland. Some 3 to 6 inches of snowfall is currently expected for Mammoth Mountain Sunday afternoon into the evening.
As mentioned above…..with the freezing level lowering through Saturday….it is natural to believe that our high temps will lower into the 30s by Saturday as well.
