A Taste Of Summer By Mid Week!……Then Cooler over the Weekend as Trofing Returns…..

Latest Guidance shows a continuation of the trend of upper ridging that builds in tonight into Tuesday then Flattening on Wednesday. High temperatures will likely climb a good 5 to 10 degrees above normal by Wednesday with highs in the mid to possibly upper 70s. Strong daytime sun of June will work with surface heating over the high elevated land of the High Sierra for some isolated showers with thunder possible Wednesday afternoon into the early evening with the action shifting east over the weekend. The latest GFS continues its forecast of trofings this weekend…..and so expect gusty afternoon and evening winds out of the WSW to 30 MPH along with clloer temps. The models suggest temps to cool back into the low 60s by Sunday. The upper trof will be a dry one over Central Ca. At the moment, the Dweebs feel that 8000 foot level temps should remain about 5 degrees above freezing Sunday morning. However the lower elevations may flirt with freezing if the winds decouple long enough for the cooler air to settle. Of note, the ECMWF has trended quite cool with the 00z Monday Run with the 700mb zero degree C isotherm down into Northern California.
