Our weather front sailed through nicely early this morning bringing close to 2 feet over the crest and some 10 to 15 inches around town. Short wave ridging will be sufficient to give us a nice break in the heavy snowfall Saturday afternoon, and although there will still be periods of snow, there will also be periods of sun!

5:45pm update:

The next really heavy snowy period will not develop until very late tonight and more likely after midnight. The period after midnight and before noon looks pretty ominous,  as the main upper low moves in and out of California. The upper trof should clear the Sierra by mid to late afternoon Sunday. Expect another break in the heavy snow mid afternoon Sunday into Sunday evening. The next short wave will redevelop more snowfall, again about midnight Sunday night with the last in the series late Monday night.


In between short waves, lighter amounts of either snow or snow showers will still occur.  The Dweebs still believe that Mammoth Mountain will get up to 4 feet storm total…..hopefully a little more…..

The high resolution model WRF has the next short wave increasing the snowfall late Sunday night…especially after midnight. Another 6 to 12 inches could fall by noon Monday.

The WRF has yet another colder arctic system the the Dweebs will keep an eye on for the period, midnight Monday night into noon Tuesday.  Typically…the WRF beyond 48-60 hours is not as good as the Global models. The GFS has the Arctic low progressing east quicker with no over water trajectory lending to more of a snow showery pattern rather then the wetter WRFs scenario of another 1 foot plus between Late Monday night and noon Tuesday.  There will be plenty of time to adjust for this frigid system.

Fair, breezy and cold is the word Wednesday…then little wind in town with strong Mtn inversions developing Turkey day into Friday. 

Way off in Fantasy land…..the Dweebs are also keep an eye on a system that is moving into eastern Asia at the moment….. That may become a player in our weather about the time that visitors live for home a week from this Sunday.

Dr Howard and the Dweebs…………………..:-)
