Colder Temperatures Arriving Wednesday

South Shore Snow Details

A pre-Thanksgiving winter storm will bring rain and heavy snow to the Northland starting today. Rain will continue to move into northwest Wisconsin this morning while rain and snow move into central and north-central Minnesota from the west. Precipitation will gradually transition to all snow today and tonight as colder air pours into the region. Snow will be heavy at times tonight and early Wednesday morning over portions of northeast Minnesota. Snowbelt areas of northwest Wisconsin may see 1 to 3 inch per hour snow rates tonight and Wednesday. Snow tapers off from west to east Wednesday and Wednesday night. Thursday will see light lake-effect snow showers lingering over portions of northwest Wisconsin.

A rain/snow mixture begins today, changing over to all snow by tonight and continuing into Wednesday. South Shore lake-effect lingers into Thursday. Snow amounts may still change, but most of the Northland should see accumulating snow. The highest snow amount probabilities are located over northern Iron County in northwest Wisconsin where heavy lake-effect snow is expected.

Colder air arrives Wednesday behind the departing low pressure system, with these cold temperatures lingering through at least next weekend. Expect high temperatures in the 20s with lows in the teens to single digits. Overnight into early morning wind chills in the single digits to around zero degrees are likely.

Warm lake temperatures and winds off the lake today will lead to a big difference in snowfall amounts from the lakeshore to the top of the hill in the Twin Ports and along the North Shore with areas along the higher terrain on the South Shore getting the most.
