Illinois, North Dakota, Ohio, New York, Texas, and Georgia Brace for Life-Threatening Windchills as Brutal Arctic Cold Hits Sunday Morning

ILLINOIS — A powerful surge of Arctic air is set to deliver dangerously low windchills across central and eastern states this weekend, with some regions forecast to experience 40° to 50° below zero by early Sunday morning. The incoming cold outbreak marks one of the most severe temperature plunges of the season so far, extending from the Northern Plains through the Midwest and into the East Coast and Deep South.

Northern Plains: Windchills Plunging into the -40s

Forecast models show North Dakota taking the brunt of this Arctic collapse, with windchills in the -40s likely before sunrise Sunday. This level of cold can cause frostbite within minutes, and officials are urging residents to avoid unnecessary travel.

Midwest: Illinois and Surrounding States Face -20s to -30s

Across the Midwest, including Illinois, Iowa, Wisconsin, and Indiana, windchills are projected to fall into the -20s and -30s, creating dangerous conditions statewide.

Naperville and surrounding suburbs may wake up to windchill values approaching -25°, driven by strong northwesterly winds and sharply falling temperatures.

Ohio Valley and Northeast: -20s and Deep Freeze Conditions

States such as Ohio and New York will see widespread -20° windchills, with colder pockets drifting even lower in rural and lake-effect regions. Travel concerns will escalate as blowing snow and icy surfaces combine with bitter winds.

Southern Plains: Texas and Oklahoma Hit by the Coldest Air of the Season

Even the Southern Plains will not escape the Arctic intrusion. Texas and Oklahoma are forecast to drop into the single digits and teens, with windchills near 0° possible in northern and central parts of both states. For regions accustomed to milder winters, this temperature crash poses risks to exposed pipes, livestock, and vulnerable populations.

Southeast: Georgia and Surrounding States Turn Sharply Colder

The cold front continues all the way to the Southeast, where Georgia could see windchills dipping into the teens and low 20s. While not as extreme as the northern states, the sudden transition from recent mild conditions could still cause disruptions.

Residents Urged to Prepare for Life-Threatening Cold

Meteorologists warn that this Arctic outbreak will be fast-moving, widespread, and severe, affecting millions of people across the country.

Residents in impacted states are advised to:

• Limit time outdoors during peak cold
• Ensure pets and livestock are sheltered
• Prepare homes and vehicles for extreme temperatures
• Check on elderly neighbors and vulnerable individuals

Conditions are expected to moderate slightly after Monday, but another round of cold cannot be ruled out.
