Computer model trends for the potential system for Sunday through Tuesday (Storm track is the dark red line on map) Expect more changes to this map in coming days. Still way too early to talk about how much snow could fall but both the blue and green outlined areas on map could get accumulating snow sometime between Sunday and Tuesday, March 4-6.

Thicker cloud cover for most of us today but temperatures were still on the mild side with highs in the lower 30s in far northern Minnesota to the mid 30s to low 40s elsewhere with even a few locations in northwest Wisconsin getting into the mid 40s! Surface map from late this afternoon featured a cold front to the south/east of our area with high pressure over the eastern Dakotas/western Minnesota. Winds aloft are out of the southwest which continues to pump milder temperatures into the upper Midwest as we near the end of Meteorological winter 2017-2018, only one day left!
Quiet weather continues for tonight and Wednesday as high pressure passes through the upper Midwest. Lows tonight will range from the single digits in far northern Minnesota to the lower 20s in eastern Minnesota and northwest Wisconsin. Highs Wednesday will range from the upper 20s to middle 30s for the final day of February 2018. Partly to mostly cloudy sky conditions will likely continue through Wednesday.
An area of low pressure will track from the central Plains toward the Ohio Valley from Wednesday into Thursday. The main impacts out of this storm will remain south of the Northland, but a trough extending into the upper Midwest could be the focal point for a little bit of snow Wednesday night-Thursday morning, but right now that looks to affect areas of southern Minnesota into north central Wisconsin not so much in our area.
