January 21st Update:

No real changes today with the wave coming through tonight and again Sunday.  I had a look the 500mb Vort field for the 26th.  The consensus is that the short wave is going to split over Central CA, including the vorticity field Sunday. This makes for a challenging outlook precip wise, for Mammoth. The Dweebs will update in a few days.   Needless to say, Tahoe will do much better with this storm than Mammoth. The following week shows the upper jet pushing further north, and so it looks mild and dry.

Next Storm Possibility around the 4th of February….

The MJO has done an about face this morning in backing off on a significant -EPO and -WPO teleconnection for the end of the week. All models now rapidly weaken the MJO in phase 7.   This means the the upper jet will remain to our north this week. That Is not to say that there will not be some very light snowfall.

Outside of the high level tropical moisture covering Central California on and off this week, there will be two waves of low pressure that will come through. One Tuesday and the other the end of this week.  At the moment, the jet stream remains to our north on these systems. The Tuesday storm shows only .10 inches of moisture giving possibly up to an inch of snow over the crest for Mammoth Mt Tuesday night.  Next weekend could bring light to possibly moderate snow fall to Mammoth Mt, Saturday night through Sunday night.  The Dweebs will just have to keep an eye on the upper jet..

Temperatures this week look to be in the upper 30s to mid 40s in town, with lows in the 20s. Winds will be on the lighter side in town with moderate winds Tuesday over the crest to 55 mph. Winds will be light to moderate on Mammoth Mtn this week until next weekend when they will pickup substantially.

At this time no major storms are expected for Mammoth Lakes…this week…

However, in some of the models…the upper jet gets closer to our area briefly….Saturday night and Sunday this week….that would have the best chance of moderate snowfall…..maybe….
