Wow! snowfall rates are 3 inches an hour now on Mammoth Mountain!  Between 5:00AM this morning and 9:30AM; 12.5  inches fell at the Main Lodge in 4.5 Hours. That’s 3 inch’s an hour! Total since Saturday evening is 27 inches.

This is truly a dump, thanks to the Atmospheric River!

Snowfall totals are on track for at least 5 to 6 feet on the Mountain by Wednesday AM.

After this storm is over, snow showers will continue Wednesday. It will be dry Thursday and Friday.

There is a weak system that is splitting Friday night then another storm beginning Saturday morning that will bring solid moderate amounts into Sunday morning. About 1 to 2 feet. Sunday could be a bit of a break, then another system will bring a foot plus Monday and Monday night. The last in the series looks to be a moderate storm as well Tuesday night the 18th through the 19th.

Longer Range:

If all works out, we will have an extended break beginning the 20th.  There is some validation in this estimate based upon the MJO. Tropical Forcing…

See the RIMM Phase space w/MJO.

The MJO goes into Phase 2 which trends to be dry in January.  SEE Graphics below.
