The first Winter wave of cold air has been marching south from Canada and will push through much of the nation. Wind Chill Advisories continue this morning in portions of the Northern Plains. Wind gusts above 20 mph at times along with temperatures below zero are knocking down wind chills to the 25 to 35 below range.
Temperature will have a tough time climbing above zero in parts of the Upper Midwest today. The cold air will start to move east through the Great Lakes Tuesday.
The blast of cold temperatures will expand into the Ohio Valley and Northeast for the middle of the week.
By Thursday, the cold air will have pushed into the Central Plains and New England. Highs will only be in the single digits above zero from Bismarck to Chicago.
The center of the cold air moves across the Northeast on Friday. For the upcoming weekend, a stronger blast of Arctic air will push into the Northern Plains. Temperatures will remain well below average.
