An area of low pressure tracks down the CA coast Sunday into Monday. The latest model runs bring it close enough to spread light snow into the Sierra by Sunday afternoon and clearing out by Monday morning. The latest trend is for a farther west track, which means less moisture making it into the Sierra and a lower snowfall forecast.
By Monday morning we could see 1-3 inches of new snow on the mountain, and 1-2 inches at the base. Highs in the 30s for Sunday into Monday. Gusty winds with mountain top gusts to 30+ mph from the southwest Sunday, switching east for Monday and gusting to 35+ mph.
If you are traveling home on Sunday afternoon/evening, plan for possible chain controls and delays on the highways.
Tuesday thru Next Weekend:
Tuesday through next weekend high pressure builds in with highs in the 30s on the upper mountain and warming into the 40s at the base. Expecting sunny skies and beautiful weather for New Year's Eve. Overnight lows for New Year's Eve down into the 20s.
New Year's Day a storm moving through to our north could bring some clouds. Then we should see some sun again Thursday and another system to the north Saturday & Sunday could bring more clouds. Winds could still be gusty up top, gusting to 30+ mph through the period with the storm track just to our north.
It looks like we could transition to a colder and more active pattern for the 2nd week of January. We could see below-average temperatures and cold weak-moderate systems dropping down from the north/northwest through the week.
