This week will highlight another Cold Great Basin Trof windy weather in the high country Wednesday and gusty winds for the Owens Valley Thursday……….The weekend looks fair and warmer with highs recovering some 20 degrees from Thursday’s temps……Longer range models still bring hope for a wet system about the 15th…..

For all interested, the Snow Phone is back on line.

Thank you for your patience.

9:25AM Wednesday 9th

(Beautiful morning in the high country. Winds calm, temperature 42 degrees at 9:30AM)

An inside slider type storm will push into Northern CA tonight, beinging an increase of wind beginning this afternoon.  Highs today in Mammoth will be in the mid 40s. Winds will increase late today and tonight, with the chance of snow showers developing after midnight through mid day Thursday.  WInds in the Town of Mammoth will be the strongest Tonight with gusts to 40 mph, then post frontal winds out of the north will highlight areas along the highway 395 corridor.  Stronger North winds are expected to develop for the Owens Valley beginning around 8:00AM, continuing into the night Thursday.  WInd Advisorys are included in the Weather Service forecast all day Thursday with gusts 40 mph to 60 mph possible. It will be a dry front for the valley with snow showers in the high country. For those traveling south through the Owens Valley, it will be best for low profile vehicels as strong tail winds provide for great gas mileage on Thursday! If your headed north, well…not so good!

Thursday will be breezy and cold on Mammoth Mt with wind chill factor  below 0 on the Mountain. Highs in town will be in the upper 20s with lows in the low teens.

The gredient will relax Friday with a warmer day as ridging builds in. Low 40s are likley to return Friday with little additional warming over the weekend. Later Saturday and into Sunday may breeze up again as a system passes to our north.  Highs will continue into the 40s with nightime lows in the teens and 20s this weekend.

In the extended outlook, the Tuesday storm next week, looks to mainly give the Pacific NW south to the Northern Sierra, best odds for meaningfull snowfall. At this time, Mammoth would be in for light amounts (1 to 6 in). This of course is preliminary because of the distance in time.

The Dweebs will have a better handel on it all later this week.   BTW, there are several sytems expected expected to affect Northern CA later this Month.   Hopefully some of that gets far enough south to make a difference here.

It will be a warmer day today Tuesday in the high country. Highs will climb into the low 40s and winds will be light. Althrough little change in temperature is expected Wednesday, the winds will be up.   Another cold Great Basin Slider is expected Thursday with about 15 degreees of cooling and a skosh of snowfall. (Less than an inch) Highs on Thursday will be in the upper 20s.  The latest models return upper ridging to our area this Friday followed by a Trof to our north on Saturday Afternoon and evening. Although Saturday/Night looks dry, it may be quite breezy. Temperatures will recover quickly from Thursdays system, for Friday. It appears that the pattern acorss the Eastern Pacific will be becomming more progressive. There is a meanningful storm in the models for Tuesday, next week…..Even a weak AR with it.  Stay tuned!!!

Pattern Change will bring low end moderate amounts of snow this weekend with a fair early next week…Milder Temps is possible next Thursday into Saturday the following weekend…..

Mammoth Mt may pick up close to a foot of snow this weekend…Although not what we hoped for, still a decient amount to freshen up the base.   There are two systems…One that is taking a track a bit more to our south tonight as compared to what it looked like earlier this week. The track of the Upper low passes east near Santa Barbara, into Southern CA. That system will help to moisten things up for the colder more dynamic system headed in Friday night into Saturnday. All total, about in inch of water EQ is possible over the crest.  Snowfall amounts of some 4 to 8 inches is expected at 8000 feet and 8 to possibly as high as 10 inches over the crest.   Snowshowers may linger into Saturday evening.

The storm kicks out Sunday with slowly moderating temps early next week. The West Coast ridge nudges closer to the west coast Tuesday with the next upstream system diving south into the Rockies Wednesday.  That will keep our weather dry cool and a bit breezy Wednesday. Milder temps are expected Thursday into the following Saturday. The upper flow becomes west/south westerly by weeks end with a moist upper flow approaching the west coast.  Well see how it all develops.  In the meantime, enjoy the freshies this weekend!

Long Awaited Pattern Change at Hand as Long Wave or Adjustment Wave develops offshore. Snowfall returns to the high country Thursday….Then possibly on and off into following week….

1:25PM  Monday. the 28th

New ECMWF came in and splits the Trof more than GFS.  So amounts at this time look to be more in the 3 to 6 inches range rather than 8 to 10 over the crest. However, there is always the possibility of getting a bit more.  Another wave will come in Friday Night with another chance at light snowfall Saturday. We still look good for at least a foot total over the crest by weeks end with the unsettled weather lasting into early next week. There are other possibilities out there in the week 2 period.

New Strato warming event under way with potential effects over the far west mid month.

The long awaited change in the pattern will develop by the middle of the new week bringing the possibility of moderate snowfall back into the high country Thursday.  Although the pattern change for Central CA, is not expected to be associated with an AR, it will bring a good shot of snowfall to the high country, beginning this Thursday and even possibly into the following week depending upon which model you look at. Latest Sunday 12Z GFS Deterministic Model run has about a foot of snow over the crest by Friday morning with another shot coming in Saturday and another Monday a week away.   Hopefully the hits keep right on coming to where we might get a few feet of snow by the end of 2nd week of March.   The first system is pacific born, and so it will be warmer with higher snow levels while its successors bring colder systems ,as the Long Wave once again develops to our east.

 

More Later……:-)
