December 26, 2012 is the last storm we had that dropped 1-2 feet on the mountain. Almost a year ago! Not too many changes this morning other than to slow the storm down with an onset later this evening. The heaviest snow is expected to fall in the early morning hours. With the slower speed of the storm we will see the snow showers last through the day on Saturday.
No change in the forecast model precip output overnight. Not an overly impressive amount of precip with this storm but it's a very cold storm with 20:1+ snow ratios. We should see 10-15 inches overnight at the base with another 3-5 inches Saturday for a storm total of 13-20 inches. Up on the mountain we should see 15-18 inches overnight with another 3-6 inches Saturday, for storm totals of 18-24 inches.
This storm reinforces the cold air through Monday with highs staying in the 20's. We will most likely continue making snow around the clock over the weekend and there should be a decent amount of terrain open for the first week of December. The flow turns more Westerly as the ridge builds off the coast starting Tuesday so daytime temps start to warm into the 30's and 40's by midweek.
The GFS forecast model was the outlier in showing no storms through next week, but now has come more in line with the other forecast models. They all break down the ridge off the coast enough for a decent storm to push into CA next Thursday into Friday. Some of the model runs suggest another storm on its heels for the weekend of the 14th. They then have the ridge building back in to start the week of the 16th. So only about a 5 day break before our next chance of snow after this storm.
