  • Bench Locations, 2-4 inches
  • Valley floor, trace-2 inches

Sunday-Wednesday, November 13, Off and on snow light snow possible:

  • Above 6k feet, moderate accumulations possible
Update (Saturday AM): Storm has come in real nicely… bumped up totals. Includes second wave coming in tomorrow! Gone shredding! …PH…
After a couple more days of being under a ridge of high pressure, north stream of split flow will sag into the area on Saturday afternoon as a first impulse moves through.  Precip will be rain/snow mix initially in the valleys on Saturday before changing to all snow in the afternoon.  Precip could also be heavy at times allowing for possible accumulations in lower elevations.  Mountains should get a solid dump through the evening hours before snow tapers to showers overnight.  6-12 inches is likely above 6,000 ft.  
Large trough develops in the Center of the country, allowing for the Jet Stream to park itself just north of the area for several days.  
Another impulse will follow on Sunday that should add a little additional accumulations in the mountains.  Similar impulses will make their way along the jet stream through mid-week and will likely affect our weather.  Exact position of the Jet stream will be critical in determining how much snow we get.  Currently, it looks like we will be on the southern fringes, which would mean moderate accumulations would be possible.  If the Jet sets up a little farther south than currently progged, it would create a possibility for significant accumulations. It will be interesting to see how this develops as we get closer.
I was asked yesterday on our Facebook page if the “epic” storm that has been affecting Alaska was associated with our forecast for precip on Saturday.  Strictly speaking, no, as that low is tracking through the Bering Sea up into the Arctic, however, some of the moisture from the southern end of the storm will split into the Gulf of AK and develop into a Low of its own which will get entrained into the jet and will definitely play a part in the moisture that may bring us snow early next week.
Later next week, the Jet should move north and east of the area as a shortwave ridge builds over Utah.  That weekend, the 19-20, may be the beginning of a series of strong pacific lows that will begin to affect the area. Currently it looks like we may see storms approximately every three days through Thanksgiving weekend. Again, this is a long way away and things can change, but the models have been fairly consistent in painting this picture that last several days.
Solitude is Open, Brighton opens tomorrow, Alta and Snowbird are on their heels for next week! Happy Shredding!
