The See-Saw of Spring will continue this week with a rather potent system moving into the Sierra Wednesday night. The system does not have a lot of over-water trajectory. However, it has a rather large 500mb to 1000mb; 522dm to 528dm thickness pool that will settle over Ca Thursday into Friday. With warm antecedent conditions in place, no doubt there is going to be some serious wind Wednesday night! The QPF with the storm is not overly impressive, with possibly .50 to 3/4 of an inch over the crest. The bulk of the snowfall for the high country will be between 5:00am and 12:00 noon Thursday. So possibly 6 to 8 inches on the sesame plot and 10 inches over the crest….just a good guess at this time. I am currently looking at 2 to 4 inches in town by Thursday afternoon. Thereafter…it will be a cold snow showery pattern into Friday with possibly some upslope Friday? Temps are headed for near record lows for this time of the year with highs in the 20s in town Thursday and in the teens at 10,000 feet. Some single digit lows possible Friday AM.
Retrogression is now in the cards toward mid month and so the next series of systems toward mid month may give Mammoth Pass a serious boost to an already high snowpack………
