Blue Bird Morning in Progress….Storm Total On Mammoth Mt 5.5 to 7.5 Feet!…..Over 3 Feet in Town

Mammoth Mountain reports storm total 64 to 92 inches!

Some areas on Mammoth Mountain approaching a 20 foot base!


The Dweebs received reports from locals of the best powder of the year so far as the top of Mammoth Mountain opened Saturday. The weather maps this morning indicated a short wave ridge over the area  keeping us precipitation free today. Crystal clear ultra blue skies this morning were expected to cloud up somewhat later today as there was enough cold unstable air aloft for this reason. High temps today in town were expected to be near 30 degrees with lows upwards to the mid 30s on Washington’s Birthday.

The next weather system appears to be developing far enough west off shore to keep most of its precip out of our area. Although there will be plenty of cloudiness, and some possible snow showers Monday night or early Tuesday Am…..The main effect of this upper low will be clouds and some increase in wind over the crest. Temperatures early next week will remain below normal in this NNW flow aloft upper air pattern.

Longer Range:

The longer range looks more interesting. Last nights 00z global models had significant differences. The Canadian and American GFS has a very cold plunging upper trof that will bring mainly light to moderate amounts of snowfall to the Eastern Sierra Thursday/Friday. The European on the other hands forms a closed low up off the coast of the Pacific Northwest which allows the upper pattern to bow out off shore and tap subtropical moisture from under the upper ridge north of Hawaii. The latter pattern is slower and wetter pattern while the former pattern is colder and dryer.  The ensemble’s favor the colder dryer scenario at this time. However, the very new 12z Sunday GFS run just took a turn to follow a match more like the European. Whether this works out is still unknown at this time as this is quite a change from the number of GFS runs showing the former colder dryer scenario.

Stay Tuned, the Dweebs have you covered!………………………………..:-)

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.
