MADISON, Wis. - Very cold air is poised to move into the area southern Wisconsin for the next week, with two waves of Arctic air descending from Canada and leading to temperatures up to 30 degrees below average.
In the wake of a large storm system moving through the Midwest, much colder air will rush into southern Wisconsin on Thursday, according to News 3 meteorologist Bob Lesh. As the low pressure system moves away, it will get stronger, increasing the northwest winds and drawing Canadian air to the south.
Temperatures will only be in the mid teens for highs by Friday and Saturday, with the low Friday night dipping near zero.
Another storm system will move through the country on Sunday, this time mainly to our southeast. Because of this difference in track, we will see highs only rising into the lower 20s on Sunday, and we should receive a quick shot of snow Sunday through Sunday night. At this point, it looks like we will end up with 2-5 inches of snow before it winds down Monday morning.
As that storm departs, winds will pick up out of the northwest and bring even more Arctic air into Wisconsin, and with fresh snow on the ground, the results will be dramatic, Lesh said. Lows will be below zero for Monday and Tuesday nights, and highs will be in the single digits on Tuesday. Since it will be windy during that time period, wind chills could reach -30 during the coldest part of the day.
State officials are reminding residents to protect themselves against frostbite and hypothermia. People should limit their outdoor activity.
