Wet weather is expected for the Northland today and tomorrow. Rain will develop today and last into tonight. Cold air aloft looks to switch some of our precipitation over to snow later tonight into tomorrow. Parts of northern Minnesota and the Northland could primarily be seeing snow and wintry mix on Wednesday. The snow will likely be across northern Minnesota and around the shorelines of Lake Superior. We turn colder behind this system with highs in the 30s both Thursday and Friday.
Tracking rain and snow
An area of low pressure will bring rain to the area today with periods of rain mixing to snow tonight into Wednesday.

This explanation will involve a little modern physics.
A south wind overnight will help us start to warm up quicker with highs this afternoon peaking in the lower to mid-20s.
Wind chills will stay at least 30 degrees below zero to even some 40-below temps across the Northland on a very bitterly cold Friday.
There is a wind chill warning through noon Friday for all of Northeastern Minnesota.
