The arctic air gripping the Northland will continue through at least the middle of next week. Expect daily high and low temperatures about 15 to 25 degrees below normal for this time of the year. There will be periods of widespread dangerous wind chill values of 25 to 40 degrees below zero, including tonight into Saturday morning. These wind chill values can cause frostbite on unexposed skin in 25 to 30 minutes, so bundle up! There will likely be some light to moderate snow Sunday and Sunday night when a low pressure system lifts through the Upper Midwest and Great Lakes.
