Sunday 7:45 AM

Although the focus of the “AR” will be over Northern CA this Coming Week…Mammoth Mt could still pick up 18 to 24 inches of wet snow between Tonight and Tuesday evening…..  These are two storms back to back that are each moderate precipitation producing storms. There will be a break Wednesday and Thursday before another moderate storm hits Friday…..The Dweebs definition of a moderate storm is one that produces between 6  to 18 inches of snow over a 24 hour period.


9:00AM Saturday:

Snowfall amounts were in the 3 to 4 inch range over the upper elevations with a trace to an inch or so in town.


The focus now shifts to Sunday night through Tuesday time frame as deeper moisture moves into the pacific NW south to Central CA.

This morning, CRFC did pull back on the QPF between Sunday night through Tuesday to less than an inch for Yosemite.  Obviously the models have become drier for Central CA. However, this is a day to day situation and the Dweebs will update Sunday when were are within 24 hours of the beginning of the AR that will hit parts of the west coast.



5:20PM Friday..


Late tonight and Saturday AM 2 to 3 in town and 3 to 6 over Old Woolly…



The Models are really starting to pick up on quite the wet pattern next week and possibly beyond. Even Southern CA may turn much wetter later in the week and beyond….

The Dweebs are hoping that this is what we all have been waiting for..

Details Sunday…….



After what was deemed our January thaw, another active weather pattern has developed. Although the storms Thursday through Sunday are in the light to moderate range, there will be some breaks with partly cloudy skies later Saturday into Sunday morning….the only other issue is that it will be very windy at times over the upper elevations.   Looking at the outlook….Buckle Up!  There is a chance for a real AR event beginning late Sunday night with the juice really increasing Monday into Tuesday.  “A colloquial Pineapple Express maybe be touted” The Experimental model HIWPP FIM9 14-km showed a nice AR connection to near Hawaii with PWAT of up to 1.5 inches Monday and Tuesday.

If this sets up and I mean if….It will be wet base building snow with high moisture content with the snow level in the 7,000 to 8,500 range early next week. The Snow level will come down later Tuesday. Better confidence will occur by this Saturday PM for the Monday/Tuesday event so stay tuned.  Sorry Southern Calif….  Although you will get some rain, You will have to wait until the following Friday to get your Pineapple’s…Maybe


The precipitation forecast shows moderate amounts of snow Thursday night into Friday AM possibly 6 to 10 inches. Another fast-moving system is expected Friday night into Saturday AM with lighter amounts…1 to 3 inches in town and 3 to 6 over the upper elevations, by Saturday Noon.

The next system will begin to spread snowfall into the Mammoth Area by Sunday evening and continue through Tuesday….
