Impressive snow totals are rolling in today as the storm continues. The biggest winner appears to be Sundance with 4.5″ of water weight and over 40″ of snow so far. Not surprisingly, the road to access Sundance is closed and some monster avalanches have come down in Provo Canyon. Park City, Deer Valley and Snowbasin have all gotten roughly 20-30″ of snow with 1.5-2.5″ of water. A real big storm for the Wasatch backside. Little Cottonwood did poorly early in the storm but is rapidly catching up with a 19″ storm total now reported at Alta.
And its not even close to over. Most areas of the Wasatch will see periods of snow through Thursday morning. With the flow becoming more northwesterly, the Cottonwoods should do better than PC and Sundance in this phase. I expect 5-10″ more in the Cottonwoods and 3-8″ more elsewhere by Thursday morning. Winds will be strong at the ridgetops again Wednesday. Snow ratios should be moderate. Not fluff, but not too dense either.
Another very cold trough will swing in on Christmas morning. The most reliable aspect of this storm appears to be super cold temperatures. Like -5 F at the top of Snowbird and Alta. Make sure you bundle up if you are going to ski on Christmas. As with many troughs in Utah, this one may depend on the subleties of the wind direction. If there is prolonged northwest flow behind the trough it could be really good, especially for the Cottonwoods. If the flow is too northerly, nobody really gets anything. Lake-effect snow is also a possiblilty. If I had to give a number, I would say all ski areas will get at least 6 inches. We will see.
