Overview
- Snow tapered early Sunday after a fast-moving system left a broad 1–6+ inch swath from the Plains to the Mid-Atlantic, with locally higher totals in lake-effect belts.
- The National Weather Service maintains widespread cold-weather alerts into Monday for tens of millions as Arctic air spreads south and east.
- Northwest gusts up to roughly 35–40 mph are producing hazardous wind chills, from -30°F or lower in parts of the Upper Midwest to single digits in the Mid-Atlantic.
- Transportation agencies pretreated roads and continue to urge limited travel, with lingering snow and ice keeping secondary streets and sidewalks slick.
- Cities opened warming centers and emergency shelters, including Baltimore’s Code Purple and facilities in Jackson, Mississippi, while forecasts point to a gradual warmup starting Tuesday.
