More frigid temperatures ahead for Illinois, but warming ahead for Dakotas

LINCOLN, Ill. (AP) — Residents of the Midwest are coping with more bitterly cold temperatures.

In northern Illinois, forecasters say overnight lows could reach 20 below tonight. The National Weather Service says the wind chill this morning was 39 below zero at Aurora Municipal Airport.

Neighboring Indiana also has been dealing with the subzero chill, with several school districts around the state delaying their openings this morning to let things warm up a little.

Forecasters say the weather pattern that's brought the repeated arctic assault to the Midwest is unusual. Many areas are on track to record one of the top 10 coldest winter seasons on record.

But the Northern Plains could soon get a break from the cold. Arctic air has enveloped the region for a week and a half, but the National Weather Service says the jet stream will push it north, allowing some warmer weather into the Dakotas. While wind chills dropped into the minus 20s this morning, forecasts call for highs into the mid-30s tomorrow in North Dakota and the lower 40s in South Dakota.
