Monday Am Update:

Yesterdays storms dumped up to an inch of rain along the Highway 395 Corridor.  Here at .09 hundreds and so areas north of Mammoth and especially north of Tioga was mostly cutoff in the northward extent of the precip yesterday. The area of convection stretched up from the south and then NE from Mammoth, and so Crestview got plenty of rain as well.

Today, the area of best focus is shifted a bit north. The best focus is from Yosemite/Tioga northward.  Again this is the area of best focusing…however, conditions are still favorable for Thunder and rain here in Mammoth and for that matter all of Mono County. In fact, Mammoth should get more rain today than yesterday.

The Dweebs wanted to mention that there was in addition, lots of nocturnal activity on the west side of the sierra all night. An area of convectivity from about Merced that moved northward is now located over Lassen County. There were 1,000s of lightening strikes overnight on the west side of the sierra.

Showers develops this morning here in the Mammoth area. .02 hundred’s dropped here at the village at Mammoth. More rain is expected today.  Temperatures will be in the 70s today here at the 8000 foot level.  Dew-points are in the low 50s.  FYI, Dewpoints in the 50s is an area moistures wise that is usually associated with Rain and Thunder in July.


The current thinking is that the weak Trof located near Monterrey Bay will pull mostly northward today. There is quite a bit of drying that has pushed into Western Ca already. This drying at 700mb will advance into the high country over night and into Tuesday for a dry and warmer day Tuesday. Tuesday highs will climb into the low to possibly mid 80s as 500mb heights are higher. Fair weather is expected to continue into Wednesday with an area of weak instability that may regenerate some isolated Thunder Thursday and Friday followed  by a Dry and Fair weekend.

Longer range:

The longer range outlook for the early part of August is for an increase of wet thunderstorms for the high country.
