It looks like a couple of very active days and nights for both Inyo and Mono County as Deep Monsoon Moisture remains in place and at the same time, and even more importantly, the aid of the jet stream comes to play.

Today Thursday, The RT rear entry of a rather weak upper jet will provide added instability to our region this afternoon and evening. Tomorrow Friday, another upper jet, a bit stronger will provide added lift as we are under its Front left exit region.  Both of these jets adds to the more passive terrain driven convection that we experience during the Summer. At the moment, the Friday system seems stronger then today’s extra lift.  The NWS has Flash flood watches out for Mono and Inyo Counties today, tonight, Friday and Friday evening.

As a note, this pattern has the strongest Summertime forcing I have seen in several years!!


Highs in Mammoth Thursday will be in the 70s and Friday in the 60s.

Lows in the 40s and 50s.


Drier air works its way in for Saturday and Sunday.  It will be warmer…..

Rain chances are minimal and are mostly confined to eastern sections of Mono County this weekend


Another surge of moisture pushes in Monday. At this time, I do not see any upper jet support with it.
