This Summer has shown to be quite the trough’y one with very low thunderstorm days. Highs in Mammoth have run a good 5 to 6 degrees below normal this Summer.   In fact our average warmest day in July is 88 degrees, while 80 was the warmest.  We are settling in on a cool breezy weekend as low pressure from the Gulf of AK spreads cooling of some 5 to 7 degrees tomorrow in the high country.  Expect highs in the low to mid 60s on Saturday with breezy dry weather. Sunday morning, lows with range in the 30s and 40s.   Some cool spots like Devels Post Pile and Tuolumne Meadows may actually drop to the 20s Sunday AM.  Some frost is expected…..First taste of Fall?

 

Expect warmer weather with highs returning to near normal, then cooler the following weekend….Long range models continue the trend of the west coast Trof more often than not in August. this is typically a mild dry pattern with breezy weather in the high country. However, any tropical storm later this month could come into play getting caught up in the upper flow….
