Traveling over the weekend…..will update Monday night…..

Platinum Powder Alert” for this Saturday Morning

Thursday night….everything on track….. Heaviest snow fall will occur when upper flow back from the WSW Tomorrow afternoon……Eastern Sierra Blizzard….

Storm Warning through 1100AM Saturday.

Now the rest of the story…..Significant Atmospheric River possible for next Wednesday….




Wednesday AM:

After a break this morning, snowfall rates will increase again this afternoon in a colder air mass through about midnight tonight. The Dweebs expect another 5 to 7 inches in town by 1:00AM Thursday. Expect another foot on Mammoth Mt. This snow will be lighter than last night sierra cement.

On Thursday, the main cold core low will be along the North Coast as the upper jet pivots NW/SE. This sets up a windy blustery pattern here in Mammoth Thursday afternoon/night until the upper flow backs from the west or WSW Friday. Snowfall rates pick up later Thursday night and continue through Friday night. A winter storm warning is in effect for this period. Keep in mind that snowfall will be of very light density and any wind can blow it around and create poor visibility creating dangerous driving conditions. Friday is not the day to travel heading north from Mammoth.  A Platinum Powder Alert is in effect for Saturday AM with a foot or better of snow on Mammoth Mt at 10,000 feet at ratios of 15:1.  The forecast is for up to 2 feet of “Angelic Powder” for Saturday Morning.  Highs in the 20s in town and teens on Mammoth Mt.

All toll….Mammoth Mt stands to pick up 5 feet of snow over the crest….The multi storm total for the Tuesday night through Saturday AM period

Sunday may be a blue bird day. Fair as well Monday…  New storm moves in Tuesday night and the hits keep on coming….:-)


The Dweeber…………….:-)




New twist this morning in the pattern will provide for rain changing to snow later this evening then heavy snowfall expected tonight through Wednesday.  Although a Winter Weather Advisory is in effect officially, full on winter storm conditions will develop by Midnight tonight well into the day Wednesday. Snowfall amounts look to be 12 to 18 inches in town at the 8000 foot level by Wednesday late Afternoon and between 2 and 3 feet of snow on Mammoth Mt by Wednesday Night.  This is a change in the thinking from yesterday where only 4 to 8 inches was expected in town.

The “QPF”  Quantitative precipitation forecast output from the models put less emphasis on the Thursday Night-Friday storm now as far as the amount of snowfall as compared to the period late tonight through Wednesday Night. However, the Thursday Night Friday system will have lighter density snow and gusty winds,  so travel conditions may be impacted Thursday night into Friday due to blowing and drifting snow. Thus a winter storm watch is warranted for Thursday afternoon into Friday Night.

The good news is that the weekend looks pretty good weather wise. For those that want to get some light dry powder, you may find pretty good weather with some snow showers mainly Saturday. Be sure to carry chains during your Friday night trek, as the snow level will be quite low into Saturday AM.

The Dweebs expect a good 2 feet plus in town over the next 72 hours and between 4 and 5 feet over the crest….

The First half of next week should be Fab!


More snowfall is expected next week as early as mid-week…..
