Discussion:

A series of impulses within a fast, low amplitude upper flow will allow periods of showers briefly from Central Ca then mostly northward through Thursday. The nose of 150 knot upper jet will move into Central Ca Wednesday bringing strong upper mountain winds, snow showers and much cooler temps during the day to Mammoth Lakes. Temps will begin to moderate on Thursday with lighter winds for the residential areas Thursday.

WX pattern over the Pacific:

A strong REX Block developing near the dateline by Friday with a closed upper high over the high Lat’s will force west coast heights to rise going into the weekend resulting in beautiful central west coast weather with warmer then normal temps. Expect high in Mammoth in the low 60s by Saturday/Sunday.

Thereafter, the upper flow de-amps and the upper jet settles south again into Central Ca Monday into the Tuesday with quite breezy conditions over the upper elevation Monday and especially Tuesday with a slight chance of showers. It will be cooler as well the early part of next week compared to the weekend.
