Overall the snowfall forecast worked out better then most…..as http://mammothweather.com successfully forecasted between 2 and 3 feet for the upper elevations, early this past week. Mammoth Mountain reported 30 inches storm total over a 72 hour period….2.5 feet. Telemetry showed about 2.36 inches of cold liquid on Mammoth Pass.

Although the Dweebs see another system for about the 24th of April…..I am doubtful that we will experience a precip event that will dump similar amounts of snowfall for that upcoming storm near the end of the Month…..

The end of April usually brings smaller showery storms to the Mammoth area as well as in early May with a few isolated events right into June……Climo Wise….Fathers Day is usually the last frost here in Mammoth.

The upcoming week will feature a nice warm ridge that will build in Sunday into Monday. High temps today will be in the 30s then 40s Sunday and near 50 by Monday. Expect high temps to climb to near 60 by Wed/Thur. Lows at night in the 20s and low 30s.

Across the pacific, a zonal flow pattern will develop after midweek with the upper jet taking aim again on the pacific northwest. It will not be until the 24th of APRIL that precipitation/snowfall returns to the Mammoth area.

I would say that our snow pack is at peak now for the season over the upper elevations……….

Mammoth Mt began MVP For New Members The 14th! If You have been Waiting To Get In on “The Unlimited Seasons Pass” For Next Winter….You Have Only Two More Weeks To Apply…And you can start using it immediately! ($659.00-Adult) Ends April 30th…. SEE: http://www.mammothmountain.com/

It was a excellent storm over the weekend with more then 2.5 feet of fresh powder on Mammoth Mtn. Since then ridging has built into the California with above normal high temps expected all week here in the high country!

Normal highs here at 8000 feet this time of the year is in the mid 40s…today high is predicted to be 55…tomorrow 59. Lows in the 30s. So let the runoff resume!

The outlook this week shows ridging aloft that will flatted a bit mid week as the northwest receives more rainfall.

An approaching weather system from the west resumes the building of heights over California Thursday for high temps moving into the low 60s then mid 60s by Friday into Saturday. Yes, high temps will be 20 degrees above normal next weekend! Nigh-time lows will move well into the 30s….so this week into the weekend will incur quite the runoff!

As indicated below in the longer range…this Friday and Saturday afternoons, may have some diurnal isolated showers and Thunderstorms…..(Summer like) (See below)

Based upon the record highs in the Owens Valley next weekend which are in the low 90s set back in 1950 and 1989, this will not be a weekend with record highs, but nevertheless, a taste of very late spring to early summer weather!

Longer Range:

The next weather system will be approaching late Sunday….

Winds will increase Sunday……

However…the new 12z Monday GFS actually has some convective showers (Summer Like) over the Central Sierra as the first good thermal trof develops over the Sierra Friday afternoon with a convergence setting up. This again may set up again Saturday…..Isolated TSRW? Due to respect for Tom C. The Dweebs will not use the word Snow-melting showers Cu/Showers…. for 24 April

Active weather returns the early part of the next week beginning the 23rd with long range GFS bringing good cold upper low down the west coast. The system seems to be splitting over the weekend. I like the ECMWF’s idea of the slower scenario as there is a pretty strong Warm Ridge north out of Mexico that is supported by the feed back from increased thickness/Diabatic Thickness process. Also Mid Latitude Omega Block will slow things down as well….

So the less progressive solution is preferred at this time. That is until about mid week. As of note there is a 500mb-1000mb Thickness pool of 534dm with the off shore Trof. So there “may be” a period of severe WX over So-Cal when it finally makes its move east.

Have an excellent Week………………..!!!!!
