5:30pm  Sunday

This storm is certainty the creeper. Although yesterdays forecast below indicated that the front would be near Mammoth at 00z Monday. (Sunday at 5:00PM),  the updated forecast shows it will not come through until about 11:00AM Monday.  So do not expect snowfall to become heavy until well after midnight tonight…Heaviest snowfall will probably be Mid Morning Monday…. Expect good snowfall Monday into Tuesday…


Although currently closed now, Mammoth Mt reported 7 to 10 inches of snow today Sunday.

This Afternoon’s Analysis had a cold Low off the Oregon coast with a front pretty much stationary over Northern CA. Heavy precip was falling over Northern CA with strong winds buffeting the Eastern Sierra. Light orographical precip was being lifted over the Sierra in the strong SW flow.  As the upper low drops south Sunday from Northern CA, snowfall will pick up with a FROPA expected by late afternoon or early evening Sunday for Southern Mono County. Strong Vertical motion fields are indicated Sunday night into Early Monday AM.  In that the Closed Low continues south and becomes a bit cut off….it is difficult to know where the features will come east through Southern CA. Most models take it east through About San Diego but the EC had it coming east further north.  These considerations would determine the possibility of up-slope for the Eastern Sierra, Tuesday or Wednesday….


The highlights of this storm for the Sierra Are;

1. The front is progged to stall near Tahoe for some 18 to 20 hours giving them the big dump….”today into Sunday AM”. By Sunday at 500PM the front is near Mammoth Lakes.   So our heaviest snowfall will be Sunday afternoon through Early Monday AM. At some point the upper flow becomes southerly and that cuts off the orographics…. But by When???  And as mentioned earlier, will the Eastern Sierra get into a good up-slope pattern Tuesday? All these things determan how much snowfall we will get in Southern Mono County. 2 to 3 feet by mid week not unreasonable thinking….


Stay Tuned…………….:-)
