Major Arctic Air Blast Expected to Send Temperatures 20–30 Degrees Below Normal Across the Central and Eastern United States Next Weekend
UNITED STATES — A significant surge of Arctic air is poised to sweep across the central and eastern United States next weekend, with forecast models showing temperatures dropping 20 to 30 degrees below normal between December 12 and December 15. Meteorologists warn that this could be one of the most dramatic temperature drops so far this season, affecting states from the Midwest and Great Lakes to the Southeast and Mid-Atlantic.
Models Show Widespread, Intensifying Cold From the Plains to the East Coast
Forecast maps show a deep pool of Arctic air spreading southward from Canada, engulfing states such as North Dakota, Minnesota, Iowa, Missouri, Illinois, Indiana, Ohio, Kentucky, Tennessee, Georgia, and the Carolinas. The region highlighted in the coldest anomalies indicates values approaching –25 to –30 degrees below seasonal averages.
While exact temperatures will vary by state, early projections indicate:
- Upper Midwest & Great Lakes: The largest departures from normal
- Central Plains & Ohio Valley: Rapid, intense cooling through the weekend
- Southeast & Mid-Atlantic: A sharp temperature crash following mild early-December conditions
Meteorologists emphasize that the map represents departure from normal, not actual temperatures, meaning many areas could still fall into the teens or single digits depending on nighttime conditions and snow cover.
Cold Expected to Arrive in Multiple Waves
Forecasters expect the outbreak to unfold in waves, with the first arriving late in the week and the strongest surge pushing south by December 13–14. The pattern suggests:
- A steep drop in temperatures over a 24-hour period
- Potential frost and freeze hazards into the Southeast
- Increased heating demand and potential strain on utilities
At this stage, no major snowfall event is directly tied to the outbreak, but such Arctic intrusions often interact with developing storm systems. Meteorologists are watching for those possibilities in future model runs.
Residents Advised to Prepare for Significant Weather Changes
Given the large geographic area affected, officials urge residents to stay alert to updated forecasts. Sudden cold blasts of this magnitude can trigger dangerous wind chills, frozen pipes, livestock concerns, and roadway hazards if moisture accompanies the front.
Emergency managers also recommend:
- Checking home heating systems before the weekend
- Protecting outdoor pets and livestock
- Preparing for potential travel disruptions
As models continue to refine the timing and severity of the outbreak, detailed guidance will be issued for specific states and regions.
