Illinois and Indiana Brace for Dangerous Windchills Dropping as Low as 30 Below Zero on Sunday Morning
CHICAGO, ILLINOIS — Residents in Illinois and Indiana are being urged to prepare for life-threatening cold Sunday morning as frigid Arctic air moves across the Midwest, sending windchills plunging to as low as 30 degrees below zero in some locations. Meteorologists warn that exposed skin could freeze within minutes under these extreme conditions.
Dangerous Windchills Across the Midwest
Forecast models show widespread subzero windchill readings spreading across both states early Sunday, December 14, 2025. The coldest readings — between 20°F and 30°F below zero — are expected across central and northern Illinois, including areas from Peoria and Bloomington to the Chicago suburbs.
In Indiana, residents from Lafayette to Fort Wayne could experience windchills ranging from 10°F to 20°F below zero, with the cold biting deeper across open and rural areas. Meteorologists describe this as one of the coldest mornings of the winter season, with Arctic air and high winds combining for dangerous cold exposure.
“These are the kinds of windchills you respect,” said a meteorologist with the National Weather Service in Chicago, warning that even brief exposure without proper clothing could lead to frostbite. “Limit time outdoors, cover all exposed skin, and keep an eye on vulnerable family members and pets.”
Health and Safety Warnings for Residents
Officials are stressing that these windchills are not just uncomfortable — they are dangerous. Emergency services have urged residents to take precautions, including:
- Wear multiple layers of clothing, including hats, gloves, and scarves.
- Avoid prolonged outdoor activity to prevent frostbite and hypothermia.
- Check on elderly neighbors and those without reliable heat.
- Bring pets indoors and protect livestock from exposure.
Frostbite can occur in under 15 minutes when windchills drop below -20°F, according to health experts. Hypothermia remains a serious risk even for those exposed for short periods without sufficient winter gear.
Cold Pattern to Linger Through Early Week
The bitter air mass behind this system will not leave quickly. Temperatures across Illinois and Indiana are expected to remain well below normal through early next week, with single-digit lows and daytime highs struggling to reach the 20s.
Meteorologists caution that a second wave of Arctic air could follow later in the week, extending the cold spell into the pre-holiday period. Energy providers across both states are preparing for increased demand on heating systems and urging customers to conserve energy when possible.
Preparing for the Coldest Morning of the Season
As temperatures plunge before sunrise Sunday, forecasters say the safest place to be is indoors. Motorists should carry emergency kits including blankets, food, and flashlights in case of vehicle trouble.
Residents are reminded that windchill warnings and advisories may be issued overnight as conditions deteriorate further. The National Weather Service continues to track the Arctic front’s progression and urges everyone to stay updated on local alerts.
With temperatures dropping fast and winds howling, Illinois and Indiana are bracing for a bitter reminder of winter’s power.
