A combination of snow mixed with rain was falling over the western half of Minnesota at mid afternoon. This large area of precipitation is encroaching on eastern Minnesota and will arrive shortly after sunset. Since temperatures have spiked into the lower and middle 40s in east cental Minnesota the precipitation is likely to begin as rain.
Dyanmic and evaporational cooling will occur once the precipitation commences. Expect rain to mix with and change to snow in the early evening hours. A couple inches of accumulation can be expected. What's a couple? How about two to three, with isolated areas lucky to measure four inches.
South winds ease during the darkness hours. Temperatures are expected to drop below freezing overnight. Watch for slick spots if you are out late or up early.
Snow will continue in Wisconsin and northeast Minnesota Tuesday. Another streak of snow may arrive Wednesday night and Thursday across central and southern Minnesota. Through the first nineteens days of February, the Twin Cities Airport had measured only 0.05 inch of liquid moisture.
