21 inches at the Village at Mammoth and Counting…..

This has been certainly one of the more difficult storms to forecast. The idea of late yesterday afternoon in keeping the main snow amounts of the first system north of Tioga Pass/Yosemite is pretty much been thrown out with the bucket. The two little jewels (short waves) that the Dweebs wrote about two days ago are heal to heal. The weather front is stationary just north of Tahoe. So what will appear to happen, will be that the first of the two systems hit us broad side later today and tonight. The has been a tremendous amount of IR enhancement on the Satellite that past several hours. HPC QPF indicates that we could easily see double of what we have already received this morning.  Since the system will lift from the southwest…the will be a period of warmer air with it….and so snow to water ratios will go down with it being wetter…before the ratios increase again afterwords.

 The weather front is expected to become more north/south orientated by early Saturday morning so the second system will hit mainly to the south of us Saturday. It will be showery Saturday as the cold core moves through with improving weather Sunday.

Longer Range:

Although there will be a few cold showery periods between Sunday and the end of the Month….The next good sized storm will come in “about”  the 1st of March.

Thursday Afternoon Update>>>>


3:45pm Update

Looking at the current situation, it appears that the first of two systems will favor areas north of Yosemite with the greatest snowfall. Nevertheless we will get several inches in town and up on the hill.

The next system is coming in further south and will benifit the south/central Sierra better. Snowfall estimates revised down to about 3 feet+ over the upper elevation and about 18 ro 24 inches in town….through Saturday morning. The system for Friday/night looks pretty good to favor the South/Central Sierra.

Mammoth Lakes Expeciencing Heavy Snowfall This Morning….The Focus Now Moves On To The Next Storm…….

As of this writing it was snowing heavily in Mammoth Lakes…..

The next system or should I say systems will set up a long fetch and a protracted period of isentropic lift for the Southern and Central Sierra beginning later Thursday night through early Saturday morning. CRFC is painting about 3.5 inches of QPF for the Southern portion of the Central Sierra.  So given Snow to Water Ratios…..Another 3.5 to 4.5  feet of snow between Thursday night and Saturday morning is looking good for the Crest at this time. 


More Later………………The Dweeber………………>>
