Another dry cold front will be approaching Mono County Late Tuesday with moderate winds again expected….Strongest Winds will be with the steepest gradient. The timing is between 5:00AM and 11:00AM Wednesday morning.   The Planned Power Outage may occur,  well before this time….

Otherwise, expect cooler weather Wednesday and Thursday in Mammoth Lakes with highs in the 40s by Thursday after early morning lows down into the low 20s that morning.  It will gradually warm up over the weekend. The weather system is dropping down from British Columbia, CA.  The cold air dump is into the Great Basin. Pressures will build strongly East of the Sierra Wednesday and so areas west of the Sierra to the coast will have an off shore event with quite warm temperature’s. This is due to the compressional heating effect.

Next interesting weather system about the 19th

 

Note:  Moderate confidence exists for above-normal precipitation off the West Coast and into the Pacific Northwest and Northern California during Week-2, associated with anomalous troughing forecast in the Northeast Pacific that could phase with a second trough that may merge prior to this with the remnants of TS Hagibis. Remaining forecasts of above- and below-normal precipitation with moderate confidence over the next two weeks result from dynamical model consensus among CFS, ECMWF, and GEFS guidance.
