Storm still looking good this morning.

There are four distinct features here:

1. The cold front will come through Mammoth about 11:00pm tonight. The bulk of the snowfall associated with the front with occur with and post frontal. So am not expecting snowfall to really pick up until later tonight.  WSFO RNO is expecting 3 to 5 inches in town by about sunrise.

2. First 500mb short wave comes through about 12 noon Saturday. So expect strong UVM between Sunrise and about 12:00pm Saturday along with moderate to heavy snow potential.

3.  There may or may not be much of a let up in precipitation between the 1200 noon and the passage of then next and main short wave which seems to have a double vort structure and drags through about Sunday mid afternoon.  There is going to be a very heavy period of snowfall between late Saturday afternoon and 12:00pm Sunday.

4. The 3rd short wave is being depicted by the GFS as an either NW west slider or inside slider while the NAM/WRF has still has some over water trajectory. Either way it look showery for Monday Am and of course cold. Snow totals still look good for up to 4 feet over the powder fields of Mammoth Mountain and a good two feet+ in the Village.

Of note, the new GFS as a few more sliders coming down over the great basin even as late at Wednesday, I do not expect much more then maybe some Mcflurries from them…..but it will be quite cold this coming week until Thanksgiving with moderating temps thereafter…..Longest range is hinting at some over running….later the following weekend……
