Thursday July 19th Update:

Very Warm temperatures expected for the high country and Owens Valley next week with possible high temperature records Mid Week….


Wednesday Temp Update:  Hi Temperature in Mammoth was 88 degrees Wednesday.  This was the warmest day of the Summer so far and the climatically warmest temperatures of the year.  So if it does not reach 88 again or warmer this year, Wednesday would have been our climatic warmest day.


It was a very warm day Tuesday with a high in Mammoth of 86 degrees.  The models show an East West ridge which has kept the atmosphere capped with little convection in the afternoon other than a brief isolated thunderstorm over the sierra Tuesday PM.  Todays weather will be the warmest for the High Country and Owens valley with a high again near 106 expected in Bishop. The Upper high at 500MB reached 598DM over the top of Bishop yesterday and will remain there today. By Thursday AM, it slides SE to St George Utah. As it does, an easterly wave develops in its underbelly, which provides for air mass modification and good SE flow up from the deserts of SE CA and SW AZ.   The result will be a rapid increase in thunderstorms Thursday afternoon into the night.   With 700mb moisture in place, mainly diurnal afternoon and evening thunderstorms will continue into early next week. Not too sure how moist it will get by this Friday.  Will follow the PWATs and report later…  Plan on afternoon convection each and every afternoon beginning Thursday…


Next week:


The GFS and ECMWF and Canadian have differences in the strength of the continental high over California early next week.  The GFS is trying to bring a record heat wave over the southern state while the ECMWF has it warm but no records…..There has been some mention from forecasters that there has been a bias in the GFS to make it too hot.  Well see soon..  The 06Z Wednesday GFS has a large scale scorching 600DM high over Southern California Tuesday night. Both the Canadian and ECMWF are both a bit weaker with this upper high and further east.

Winter seems so long away!
