Wednesday and Thursday: This is when things kick off. You’re looking at a chance of wintry mix starting Wednesday afternoon. It’ll hang around into Thursday morning. Temps will be in the mid 40s Wednesday, then drop to the mid 40s Thursday. Not too bad to start, but it’s the calm before the storm.

All the attention then turns to Friday with the First Alert 6 Weather Day. Cold air pours in from the north late Thursday night right into Friday morning. Air temps will dip below zero and wind chills could be dangerous. Check out the latest forecast for our First Alert 6 Weather Day here.

Thursday and Beyond: Showers may linger into early Thursday morning before the system moves east, with rain tapering off quickly. Friday looks mostly dry with only isolated showers possible. Highs Thursday will be in the 60s, with Friday highs near 70.

Meteorologist Jill Gilardi said we're in for a few days of Arctic cold and wind. Here's her Tuesday noon forecast.

Friday is a First Alert 6 Weather Day, bringing the coldest air of the season with lows well below zero and highs that struggle to warm due to cloudy skies. Wind chills will likely be in the double digits below zero all day.

Once the sun comes up, things will warm up quickly today. Thanks to plenty of sun and light winds, most areas will reach the low 60s under plenty of sunshine and light winds. With low humidity, things look nice today if you have any outdoor plans on this MLK Day. Just bundle up during the early morning.

WAUSAU, Wis. (WSAW) - First Alert Weather Days have been declared for Thursday night through Sunday afternoon due to our next round of extreme cold. This round is expected to be even colder than the one we just experienced.
