Tuesday AM:

 

Forecast remains on track as upper Trof now inland over the Pacific NW, then progresses east today into Wednesday. This Trof has been the suppressant, keeping monsoon moisture to the east and south of Mono County so far this Summer.  By tomorrow Wednesday, the gates will open allowing moisture and dynamics to surge northward, eventually to the CA/OR BOARDER. Dry high based thunderstorms will begin Wednesday afternoon with an enhanced risk for fire starts in the high county that afternoon. Deeper moisture is expected Thursday into Friday with wetter thunderstorms.   The chance of thunderstorms increases later in the day Wednesday, that night and especially Thursday and Friday.  Nighttime temps will only cool into the upper 50s to low 60s Thursday night and beyond.  Details about thunderstorm coverage will be on a daily bases beginning Thursday.

High temps will be mostly in the upper 70s and low 80s after Wednesday with a lot more cloud cover.

 

For you folks in Southern Californians sweltering in the heat and humidity, FYI; dew points are mostly in the mid 60s to low 70s degrees now. That is hot and humid,  with muggy nights.  Sorry to say that this pattern is not likely to change for the next 1 to 2 weeks. Hope you have good refrigeration type air-conditioning….

_________________________________________________________

It will be very warm but dry through this Monday as Southwest flow prevails aloft. High cloudiness will occur today Friday for both Central and Northern California as the remains of old Hurricane Fabio Blow off to the NE. The usual Mono Zephyr will continue during the afternoon and early evening hours with afternoon west breezes in the 15 to 30MPH range. Highs will be in the low 80s and nights in the low 50s.

The remains of the west coast trough leaves the Pacific Northwest coast and moves through Tuesday.  Thus the dry SW flow ends over Central California and we transit to our climatically favored South to Southeast flow this time of the year. This begins the moistening process for more afternoon convection in the following days. Mainly isolated thunderstorms develop in the late afternoon and early evening hours Wednesday with deeper Southeast flow developing over our region Thursday and especially Friday. Areal coverage of thunderstorms will likely increase. The details and specifics on the pattern change still to be worked out for the high country next week as too much cloud cover can shut down convection without any dynamics. One thing for sure, it will be a lot warmer early in the period with highs in the low then mid 80s by mid-week. As the Monsoonal flow strengthens and dynamics increase Thursday into Friday next week, more cloud cover can be expected with afternoon and evening convection and afternoon and early evening rain showers and Thunderstorms, leading to cooler days in the 70s. Nights will be in the 50s for the foreseeable future at resort levels.

The Dweebs want to remind everyone that live is the deserts of Eastern California that young children and pets should never be left unattended in
vehicles under any circumstances. This is especially true during hot weather when car interiors can reach lethal temperatures in a matter of minutes.
With high temperatures expected in the 100 to 105 range this weekend and next week, temperatures inside of cars can reach 150 to 160 degrees
quickly with windows closed.
