Mammoth continues to enjoy some of the finest Summer weather in years with somewhat above normal heights and light breezes.  Thereafter, the pattern will change to one of being much cooler with showers, TSRWs and possibly a light dusting of snow to the sierra crest Tuesday and into Wednesday AM…..

WX Discussion:

High pressure will remain in control through early Saturday, allowing persistence of the current pattern through the Day. High temps will range in the upper 70s with lows in the 40s. A weak upper low “currently off the Northern Mexican Coast this morning” is moving northwestward. By Saturday night, the system lifts though Central CA, increasing instability for the chance of showers during the afternoon Sunday. These will be mainly diurnally driven. What is more important is that Sundays moisture primes the air mass for the next cooler system dropping out of the Gulf of AK Monday Night.  There will be a build-ups or isolated TSRWs Sunday.  There will be a break Monday,  By Monday night expect an increase of upper forcing again which increases further Tuesday. This goes along with the front left exit region of a 80 knot upper jet being over Mono County by Tuesday PM.   Although the focus is more north of Mono County, Showers and a few thunderstorms are possible Tuesday and Tuesday night.  By Tuesday night a dusting is possible above 9000 to 9500ft.


Expect highs in Mammoth on Tuesday in the upper 50s with low of about 30F Wednesday AM

Warmer weather will return Thursday into Friday.
