The big question is the forecast storm track. (What else is new?) Most models suggest the heaviest snow (3 to 6 inches potential) will fall north of the Twin Cities. Some models still suggest we could eke out an inch or two around the Twin Cities.

Could we salvage a (barely) white Christmas on Dec. 23?

Here’s the European model snowfall output.
