Weather Synopsis for Northeast Minnesota and Northwest Wisconsin
A much sunnier day compared to what some of us saw on Saturday, although there has been an area of low clouds covering far northern Minnesota for most of the day, but those have been eroding from the south this afternoon. Highs today running near to around 5 degrees above normal with highs ranging from around 20 to the lower 30s with areas of haze which has reduced the visibility to between 5-9 miles in some locations.
RAP model analysis from Sunday afternoon shows a NW flow aloft covering the upper Midwest with an upper low to our SW, near eastern Nebraska. 850mb temperatures across the Northland ranged from 0 to +2C.
Looks dry through Tuesday under partly to mostly cloudy skies. Not much of an airmass change through Tuesday with 850mb temperatures holding right around 0C or within a degree +/- of 0C.
Lows tonight and Monday night in the single digits and teens with subzero lows possible for some of the traditional cold spots. Highs Monday in the 20s to lower 30s. Highs Tuesday in the 20s.
Little cooler for midweek and we could squeeze out a minor snow event sometime in the Wednesday-Thursday time frame, maybe around an inch of snow for some of us.
Significant warming takes place late this week/upcoming weekend which could lead to Saturday afternoon highs climbing into the mid 30s to mid 40s in most of northeast Minnesota and northwest Wisconsin.
Note: There are signs beginning to show up per long range GEFS and EPS models for a pattern change as we head toward the Christmas holiday with cold arctic air possibly returning to the Northland later this month.
