Winds were ramping up over the upper elevations this morning as the latest upper trof moves through the pacific NW. Blocking over Alaska has had the effect of suppressing the upper jet south of its normal position, over Northern California. Thus it will be windy this afternoon and evening and cooler Wednesday. In that Mammoth is located in the upper jets front RT quad, no precip is expected. In fact it will be drier then normal. Dew points were in the single digits this AM and with the anticipated wind, the National WX service has hoisted Red Flag warnings for critical fire conditions today and this evening…. High temperatures will cool to the low to mid 60s by Wednesday. Night time lows in the lower 30s.
500mb heights will recover about 100 meters by the weekend and so a nice warm 1st week of Summer is expected with highs in the mid 70 for Mammoth while Low temps will move up into the 40s.
Next week looks warm; 70s then 80s….
This is the last Week of Spring as the Summer Solstice arrives Thursday the 20th at 10:04pm
Meteorologically speaking…..if the new June the 18th 12z GFSX verifies…..the continental upper high will set up over 4 corners (desert south- west) next week about mid week next week. All heads will then make the shift to the south as Monsoon Season begins over the Desert Southwest. It appears like a weak surge of moisture begins to trek north into Southern Arizona from Old MX next week. At the same time, a little SE flow may begin to move into Southern Ca by weeks end……………..it’s time!
