Our weather pattern will transit to more of a late July and early August weather pattern with 500MB heights becoming quite high over the Great Basin and California. 500mb-1000mb thicknesses are expected by the GFS to reach low 580s over Eastern CA by late this weekend into the early part of next week. This will be good enough to tie high temperature records for the Bishop AP and Mammoth Lakes with low 80s in Mammoth and between 100 to 105 temperatures for the Owens Valley, early next week. Through the middle of next week, it is expected to be a dry pattern. However, isolated thunderstorms may begin to develop my mid week. Expect some of the best back country travel this summer this weekend into next week as the high elevation snow pack is nearing normal for this time of the year. Of course the Mosquitos are probably still active in the usual areas.  Once over night lows drop below freezing they will be gone too.

The high temperature records for Bishop Monday and Tuesday of next week the 28th and 29th are 103 and 105, set back in 2001 and 1950. It is reasonable to expect similar highs then. A anomalously strong continental high will be responsible for the heat this weekend, well into next week. Some changes are in store for the holiday weekend as moisture moves up from a dying tropical storm over the Gulf of CA. This may bring the return of mainly afternoon and early evening thunderstorm’s over the sierra that weekend,  As we all know, Mammoth is usually one of the last areas to get rain from summer type afternoon and early evening storms. I will have an update later next week on the progress of such a pattern developing.
