Where we stand now:

Future prospects:

  • The December precipitation outlook offers equal chances of below-normal, near-normal, or above-normal conditions across most of Minnesota. The December precipitation outlook tilts towards below-normal conditions in northwest Minnesota. December precipitation normals range from around one-half inch in western Minnesota to over one and one-quarter inches in eastern sections of the state. The historical median snow cover at the end of December ranges from under five inches in southwest counties, to over 10 inches on the ground in northeast Minnesota (20 inches in the Lake Superior highlands).

  • The December temperature outlook emphatically leans towards above-normal conditions across Minnesota. Normal December high temperatures are in the mid-20s to near 30 to start the month, dropping to the mid-teens to near 20 by month's end. Normal lows are around 10 degrees early in the month, falling to the mid-single digits above and below zero by late December.

  • The 90-day precipitation outlook for the meteorological winter (December through February) indicates equal chances of below-normal, near-normal, or above-normal conditions in the southern one-third of Minnesota and a tilt towards below-normal conditions in the northern two-thirds of the state. The December through February temperature projection strongly favors above-normal conditions statewide.

  • The National Weather Service produces long-range probabilistic river stage and discharge outlooks for the Red River, Minnesota River, and Mississippi River basins. These products address both high flow and low flow probabilities.
