USA Weather Today: Arctic Blast Triggers Deep Freeze on Dec 11, 2025
By Elena Vasquez, Chief Meteorologist December 11, 2025 – Washington, D.C.
A powerful surge of Arctic air, fueled by a displaced polar vortex, has plunged most of the continental United States into some of the coldest conditions of the season so far on Wednesday, December 11, 2025. From the northern Plains to the Northeast, temperatures are running 15–25 °F below seasonal norms, with dangerous wind chills and persistent lake-effect snow bands creating hazardous travel and potential power outages.
National Snapshot
- Core of the cold locked over the Upper Midwest and Great Lakes
- Widespread highs only in the teens and 20s east of the Rockies
- Lake-effect snow totals already exceeding 12–18 inches in favored snowbelts of western New York and northwest Pennsylvania
- Milder air confined to the Desert Southwest and Deep South, where highs will climb into the 60s and 70s
The National Weather Service has issued Winter Weather Advisories and Lake-Effect Snow Warnings from Michigan through western New York into northern Ohio and northwest Pennsylvania through Thursday morning. Wind chill values as low as –25 °F are possible tonight across the northern tier.
Regional Breakdown – December 11, 2025
Northeast & New England Frigid with partly to mostly sunny skies outside the lake snow belts. Highs 15–28 °F. Buffalo and Watertown, NY under heavy lake-effect banding with an additional 6–12 inches likely today.
Midwest & Great Lakes Overcast and sharply colder. Chicago struggles to reach 20 °F; Minneapolis only 8 °F. Wind gusts 25–35 mph will drive wind chills to –15 to –30 °F.

Outlook & Impacts
The intense cold will peak tonight into Thursday before a modifying flow allows temperatures to rebound closer to normal by the weekend. However, another reinforcing shot of Arctic air is likely early next week.
Travelers along I-90 and I-80 through the Great Lakes snowbelts should anticipate sudden whiteout conditions in narrow, intense bands. Utilities in western New York are pre-staging crews for possible outages from heavy, wet snow on power lines.
