Zonal flow pattern in the 3 to 5 day means to bring periods of unsettled WX to the Eastern Sierra next week…..Monday looks wet with over 6 inches of new snow possible over the crest by evening…..

A few isolated snowshowers could occur today over the crest.
What the Dweebs are expecting is a series of impulses that will advance southeastward through BC today over a long wave ridge then south into California over the next two days. The moisture will shift south as the upper flow becomes cyclonically curved over Ca Monday morning and the weather will become increasing wet and windy. The deep layered moisture over the west Sunday into Monday will be energized over the Sierra by Monday Am with moderate precipitation with up to an inch possible by Monday night over the Sierra Crest. Snowfall amounts over the crest may get close to a foot while more Sierra cement conditions are expected over the lower slopes Monday with low H2O to Snow ratios. The heaviest amounts will be over the Northern Sierra with up to 2 inches of water EQ by Monday night up there.
Highs this weekend in the 50s then 40s Monday. Lows in the low 30s cooling to the 20 by Monday.
Strong gusty winds are expected Monday.
Expect another storm before the week is over…..the weather looks pretty unsetteled over all.
