Models trending a bit wetter today for the early Thursday Am storm……600 inch, 41 year record getting closer!

Just a quick update:

CRFC for the west side has about .75 and HPC over an inch now for the crest.  Looks like over a foot now for the highest elevations by Friday. Temps will get slammed by Thursday with the freezing level going from about 10,500 feet today down to 3500 by Thursday. 500mb-1000mb thickness pool still in the 520s dm.

Active pattern to continue next week with another system with some right rear jet action Sunday night for the Central Sierra. Still watching the middle of the month for system with long over water fetch……..

We could very well break the 600 inch barrier (Ski Patrol) by weeks end.

Active pattern returns Wednesday Night into Friday as nose of 130knot jet moves into Central Ca Wednesday PM….Snowfall to increase after midnight Wednesday

The See-Saw of Spring will continue this week with a rather potent system moving into the Sierra Wednesday night. The system does not have a lot of over-water trajectory. However, it has a rather large 500mb to 1000mb; 522dm to 528dm thickness pool that will settle over Ca Thursday into Friday. With warm antecedent conditions in place, no doubt there is going to be some serious wind Wednesday night!  The QPF with the storm is not overly impressive, with possibly .50 to 3/4 of an inch over the crest. The bulk of the snowfall for the high country will be between 5:00am and 12:00 noon Thursday.  So possibly 6 to 8 inches on the sesame plot and 10 inches over the crest….just a good guess at this time. I am currently looking at 2 to 4 inches in town by Thursday afternoon.  Thereafter…it will be a cold snow showery pattern into Friday with possibly some upslope Friday?  Temps are headed for near record lows for this time of the year with highs in the 20s in town Thursday and in the teens at 10,000 feet. Some single digit lows possible Friday AM.

Retrogression is now in the cards toward mid month and so the next series of systems toward mid month may give Mammoth Pass a serious boost to an already high snowpack………

Stay Tuned………………………………..

Winds on the increase again Tuesday into Thursday as several short waves head our way……More Snow On The Way!

The Dweebs had a nice break last week while soaking up some Sun and 100 degree heat in Palm Desert. Now it’s time to chill and get ready for some spring upper jet action!

It appears that there will be two significant systems to deal with…..not counting Tuesday night’s wimpy one. The first comes through late Thursday night and the other early next week. Using “Hovmuller”surface cyclogenesis theory, the energy from the first system comes through early this Friday morning and the 2nd systems energy comes through about the 13th. The 2nd system looks like it may be dampening out as the long wave upper ridge retrogrades toward the dateline…..thus weakening the upstream jet. 

Note on the Weekend system:

The storm currently in the gulf of Ak is a very deep system that will dig SSE, bringing cold showery weather to the Sierra Thursday through Saturday with a lot of wind preceding the storm. It may bring some 4 to 8 inches over the upper elevations on Mammoth MT Thursday night into Friday morning with additional lighter amounts into early Saturday in showers. The upper trof kicks out in advance of new heights falls headed into California next Monday for another round of unsetteled spring weather Tuesday into Wednesday.
