Here is the latest update. 2/22/24

Since Sunday and through Wednesday AM, 28 to 33 inches has accumulated on Mammoth Mt.

In Town, Some 12 to 18 inches.


The weather system that supplied the moisture for the last snowfall is now a cutoff low, off the CA coast. Thats Upper Low has allowed heights to rise and temperatures as well.  The next system scheuled will drop out of the Gulf over the weekend, will merge more with the off shore Cutoff on Sunday.  Late Sunday night into early Tuesday next week might bring another foot of snowfall then.







Looks like the upper portion of Mammoth Mt will receive about 3 feet or a few inches more storm total. The forecast is for 3 to 6 inches today and tonight so 3 feet to 3.5 feet seems like storm totals by Wednesday AM.   This Wednesday night through this weekend period look pretty dry. There is a cut off low developing to our SW, well off shore mid week and developing into the lower west coast by the end of this week. It does not seem to be a system that will issue Mammoth much more than wind and cooling. The system comes in with a Cold Low to the north of us.  Both lows are pretty far from us at this time.

Well see what happens the very end of this week into early the following week with the cut off low and cold low droping from the NW. Then get ready for more weather that shows up in early March.



What a mess for the forecast charts. Upper mountain could get 1 to 2 feet this week total and 6 to 12 inches in town. Lets hope we get a bit more. These systems are not strongly coming through the Sierra. The energy weakens over CA, Best areas coastal into interior, The storm ends Wednesday AM with dry weather Wednesday night through Friday into Saturday,






It will be drier than normal through the middle of next week. High temps will be in the low 40s with lows in the upper teens and low 20s. High pressure is now building from the west to the east bring the change. As mentioned yesterday, we have a change in the pattern coming up Thursday with wind and clouds. Chances of precip will increase later Friday into Sunday with heavy precip begining Saturday. The following week looks stormy with periods of modearte to heavy precipatation.   Better handel on snow levels later this new week.






A quick update to say that colder than normal temps will give way to more seasonal temps Sunday through to the middle next week. Temps will rise to the 40s with lows in the teens.  More importaintly, another signifagant Atmospheric River is possible to developing, going into next weekend. We just have to wait and see how it all comes together.


Will check back mid week…
