The snow begins just before midnight tonight and will continue through the morning Monday. The snow will end around noon Monday, so about 12 hours of moderate snow. Temperatures will be in the teens when the snow begins and cool into the single digits late Monday. This will cause light fluffy snow that will pile up fast. I'm expecting about 8" in Duluth. The morning commute will be snow covered with a few inches already on the road. Drive slow and carefully if you have to be out on the roads. Winds will be 15-20 mph out of the Northeast.
Very cold temperatures all day long. A Northwest wind blowing at 5-10 mph will keep wind chills well below zero all day. There will be some sun but it won't warm temperatures. The high will be near 0°, with the morning low at -8°.
Even colder. Wednesday the morning will feature the coldest temperature of this cold snap. Sunrise temperature will be near -20°. The high will stay subzero at -2°. Skies will be sunny. Winds will be calm so wind chills will be close to the air temperature.
I'm tracking an Alberta clipper that doesn't have much moisture with it. I'm confident we could see a light couple of inches Thursday morning. Right now it doesn't look very impressive. This will allow temperatures to warm into the teens Thursday afternoon.
FRIDAY AND THE WEEKEND:
Friday will have warmer temperature that could reach 30°! Skies will be mostly cloudy.
The weekend there is a 40% chance to see some light snow on Saturday and just a 20% chance on Sunday. Saturday temps will be in the 20's and Sunday in the teens.
