CFSv2 Precipitation forecast for the month of December.

Most of Minnesota and Wisconsin is in slightly above normal precipitation totals in December per CFS model.
Green=Above normal precipitation
Yellow=Below normal precipitation
White=Near normal precipitation
December averages at Duluth, Minnesota:
Base Period: 1981-2010
Snowfall: 17.7″
*Number of subzero nights: 4-7
Summary: Although I’m still calling for above average temperatures in December, it’s highly unlikely will have persistent warmth like we had during most of November — I am expecting a few shots of cold temperatures throughout the month but these cold shots could be transient, meaning they won’t stick around for very long, however, if the colder airmasses linger for a while, then it’s likely that my temperature forecast will bust on the high side.
Summary: Multiple storm systems should cross the U.S. during the month of December, as is always the case, the storm tracks will be crucial in determining how much or how little snow we get here in Duluth, there is also a chance that one or two of these systems take an unfavorable track which could lead to precipitation type issues (Rain or Ice instead of all snow)
