Some of the finest weather in the eastern sierra in years, continues this weekend with daytime highs in the mid 70s and lows at the night in the 50s.  Afternoon zephyr winds have been typical, in the 10 to 20 MPH range, with late afternoon breezes up to 25 MPH at times today Saturday, and tomorrow Sunday expected….  Smoke from a few lighting caused fires to the NNE has thus far been minimal in Mammoth, due to periodic weak trofing to the west and its resulting WSW flow aloft.  The upper air pattern should continue to be favorable for clean air conditions at least through Monday this upcoming week.  Beyond that, the continental high will build back again by mid week, increasing our temperatures and bringing a return of some light morning easterly flow. This will do two things. 1.  We will experiences our highest temperatures so far this Summer by Wednesday. 2. If fires continue to burn to the NNE, conditions may turn hazy again by mid-week, however  mainly during the morning hours, until the afternoon Zephyr winds kicks in.   The mid to late Summer heat wave will last through Friday. Thereafter, it all depends upon which global model you prefer.  The European Model develops light SE flow by Saturday or Sunday.  So some seasonal wind/Monsoon for thunderstorms, while the GFS develops some light SW flow again…..Which would be dry. Either way, temperatures will remain warm here in the high country….

PS. The Euro is the Air Sea coupled model….Would it not be ironic for a summer that was relatively dry to turn wet the last four days of the month of August?…..Labor Day weekend. 😉
