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.

Beautiful Week Ahead for the High Country as Meteorological Summer comes to an end this week….First week of Meteorological Fall looks Magnificant as September begins with seasonal temps then warming above normal……Super Typhoon Jebe Will constructively phase with westerlies…Effects down-stream the following weekend…..

 

August 31st, 2018

No changes in the short or medium range outlooks today. Weather to remain fair and warm through Wednesday the 5th…..  Super Typhoon Jebe has really spun up the past 48 hours and is now a super typhoon. Both GFS and ECMWF have it recurving to the North west then North next week. They both constructively phase it with the westerlies this Tuesday the 4th PDT. Expect the energy to propagate down stream the following four days and through the west coast next Saturday…..   The Dweebs are on it!!!

Little change in the weather is expected through the Holiday weekend with seasonal temperatures and cooler nights. The winds of the past weekend are abating now and we are getting back, some of that lost Summer weather, due to smoky skies. It’s a great time to be in the Sierra in Southern Mono County!

Lots of folks still concerned about a Modoki El Nino…  I guess we’ll just have to wait and see.  Still to early to call…..
