Wednesday AM:

Flash flooding was reported near the Death Valley area at about 10:00pm last night due to a small MCC that developed. Dew points soared at the Bishop AP overnight into the 50s with light rain reported at the Bishop at the sametime. Over the Southern Mono County Sierra, dew points remained in the low 30s. In that a dry southwest flow is expected to continue here in the high country today and Thursday, we should remain dry. This is because the aforementioned SW flow along with a strong 500mb upper high cell work in tandem to keep the Mammoth area Thunder-free today through Thursday night.  All bets are off beginning Friday afternoon, and especially the weekend as an upper level disturbance forces the upper ridge to tilt eastward and the flow at 700mb becomes more south/north oriented. This along with increased monsoon moisture and dynamics is expected to allow air-mass modification to occur in the Mammoth area for a return of showers and thunderstorms over the weekend. In addition, in that there is a weak Vt center that will cross Central Ca, a wave of dynamic lift may develop. Should this wave come through at night, there may be a period of nocturnal storms that would persist well beyond the usual diurnal expectation.

A drier air-mass along with increasing stability is expected to occur after the passage of a Vort center early next week.  Tuesday looks dry with warmer temps at the moment.
