Our Air Mass locally juiced rapidly the past 24 hours with the dew-point going from the teens yesterday morning to a DP of 40F this Am. That’s fast!  Rain showers were reported over the Owens Valley this morning and near Mammoth Mt as a beautiful rainbow developed at sunrise. The lower levels are now primed……and with additional moisture advection today, no doubt there will be some rain and possible thunder.  The moisture is being drawn up between an off shore trof to the the NW and the upper high over the desert SW.  Monsoon moisture is combining with the moisture from Hurricane Elaina for an extra boost.  Although the NWS has isolated TSRWs today and tonight…..The 12z Thur WRF forecast guidance shows a 50 knot upper jet moving into Central Ca late Friday morning…thus providing extra lift Friday and into the evening for the best chance of rain and thunder.

After the possibility of showers and thunder Saturday morning…the upper trof moves through and effectively pinches off the moisture feed from Elaina by the afternoon.  So Saturday PM through Sunday PM are expected to be dry. The moisture “may” surge back Later Monday into Tuesday for another round of precipitation. The outlook for early next week is clouded;  (no pun intended) as the ECMWF and GFS models are at odds with the track of Elaina early next week.

 

Stay tuned…………………………….:-)
