Yesterday’s wind storm brought gusts over 60 MPH in town.  Mammoth Mt reported 5 to 6 inches at the Main Lodge. The Dweebs figured some 8 to 9 inches fell on the upper mountain.  Today…winter type skiing and boarding returns. Highs today will be in the 20s on Mammoth Mtn.

The cold upper trough over the west will go through some morphing with it becoming more west-east oriented. The upper jet will lift north and be situated near Tahoe this week until Saturday when a final short wave moves through bringing enhanced chances for more snowfall. In the meantime, the pacific opens up, and with cold air in place, mainly warm air advection snowfall will occur with higher snowlevels; beginning late wednesday night and into Thursday. Although it will be breezy, the Dweebs do not expect the strength of winds that occured yesterday Monday, the remainder of the week .  Friday may or may not be dry. This type of pattern is a bit tricky as far as precipitation, as that although we are south of the jet axis, with live in an area that highlights orographicical type precipitation when the flow is moist and the its direction is westerly.  So even though Friday is expected to be dry, it may not be.

The last in this series of systems will come through Saturday AM.  It appears at this time to have plenty of lift. So a period of heavier snowfall is possible Satuday AM before it moves out, later that day.   At the moment, the QPF from CRFC is .63 for Yosemite between Wednesday night and Saturday.  That would suggest simular amounts as just received from yesterday’s storm.  A big Caveat is that models do not do well with warm air advective type systems in areas with orographics from distance timewise. So, we may end up with more snowfall than what is touted at this time for the Thursday through Saturday Storm.  Easter Sunday looks dry and warmer at this time with the warmer weather into early that following week.

The longer range outlook suggest more snowfall into the end of Aprial with periodic storminess through months end.
