The Jet stream over the pacific NW will sag south into Northern California the next few days bringing gusty winds tonight into Wednesday night. Temperatures more seasonal for this time of the year will develop by Thursday and into Friday with some warming returning over the weekend. Nighttime lows will cool well down into the 30s at resort levels. A modest warm up is expect this weekend and into next week.

 

Hurricane Florence is going to be a big problem for forecasters and South Atlantic states governor’s as the latest modeling shows the storm losing its steering winds, prior to landfall…. Good luck in predicting where this one goes!

Mammoth can expect beautiful warm weather this weekend under the effects of a Subtropical ridge centered to the Southwest of the Crest….The ridge weakens in a few days as troughing sets in over the pacific NW…..So cooler, breezy weather is expected midweek…

Its a beautiful weekend in Mammoth. Clear skies, above normal temps and light breezes can be expected to continue through Monday.  High temperatures in the upper 70s and lows in the 40s are the expected diurnal temperature spread.  Summer weather is expected to continue with another warm up the following weekend after a cooler breezy midweek.

High temps mid week will cool to the low 70s by Thursday with lows expected in the upper 30s.

 

El Nino Modoki still in the cards…..

Broad area of weak low pressure located over Great Basin will bring the chance of showers and thunderstorms today and Wednesday……Drier air will work back in Thursday with a breezy Friday, followed by a fair warm weekend…..Near seasonal temperatures are expected…then warmer than normal this weekend…

A weak trough of low pressure over the Great Basin today will present conditions favorable for the chance of showers and or thunderstorms this afternoon and evening over the Sierra Crest. The upper low will slowly move east on Wednesday, but lingering instability will keep
a small threat of storms to continue Wednesday for the central and southern Sierra. By Thursday, drier air moves in as high pressure ends the threat of thunderstorms. On Friday, a dry southwest flow becomes westerly due to a pretty strong trough in the Pacific NW. The exceptional strength of that upper trough is directly related to the effects of the old Typhoon Jebe, that has now become constructively phased with the westerlies. Had this phasing occurred in October, we would be looking a possible cold, windy, snow showery period here in Mammoth. In early September, that is not the case. So the weekend looks fair, and possibly a bit breezy early on, but warm.
