UNDATED (WSAU-Wheeler News) Wisconsin went back into the deep freeze this morning, after the eastern part of the state enjoyed 20-degree temperatures yesterday. Wind chills were as low as minus-30 at five o'clock in Superior, Siren, Medford, and Marshfield. Actual temperatures ranged from zero in Milwaukee to 20-below in Hayward.
Clear skies allowed the arctic cold to settle back in. Wind-chill advisories are in effect until 10 this morning for far northwest Wisconsin, and until 11 for the rest of the state.
Highs in the single digits and teens are expected in Wisconsin today and tomorrow until clear-to-partly cloudy skies.
Parts of the north are supposed to get down to 20-below again tonight, and the next warm-up and snowfalls expected on Wednesday -- when temperatures above freezing are predicted for the Madison and Milwaukee regions.
