It's baaaack!

Our one day thaw is history, and Minnesota's sub-average winter cold is back. Sub-zero temps have already invaded northern Minnesota again, and temps in the teens have made it as far south as the Twin Cities. Deep blue is the favored color on the temperature map, ans another batch of cold air oozes south from Canada today.

This time it comes with another fresh coating of snow. An upper air disturbance riding over the cold dome is sparking some light snow. The snow increases from west to east today across Minnesota. It should begin to reach the Twin Cities metro by late afternoon, with most of the snow falling this evening into the wee hours of Friday morning.

Bottom Line on snowfall today and tonight:

Expect snow to break out in western Minnesota during the morning and spread east toward the Twin Cities by late afternoon. The start of the PM rush should be fine, but snow may begin during the latter part of the PM rush in the metro. Most of the snow will come down this evening and tonight. Snowfall totals of 1" to 2"+ are likely for the metro. The highest totals up to 3" seem to favor the north metro to St. Cloud.
