With the spectacular cold event now spreading over much of the contiguous U.S. (and still expected to bring 30 below zero temperatures in Yellowstone Lake, WY tomorrow morning) the snow forecast for the next 8 days shows only 6 states that should miss snow (graphics courtesy of Weatherbell.com, click for full-size):

Those states are South Carolina, Florida, Louisiana, Mississippi, Texas, and Arizona. While it’s still very early, the 10-day forecast shows a potential major snowstorm for the mid-Atlantic and Northeast states late next week.

The 7-day average temperature departures from normal really are exceptional in their geographic extent, intensity, and persistence, with widespread 15-25 deg F below normal temperatures…averaged over 7 days:

Some locations in Montana, Wyoming and Colorado will have temperatures ranging 50 to 60 deg. F below their seasonal norms in the next couple of days.

It will be interesting to see if this month ends up being one of the coldest Novembers on record for the U.S.
