Overview
- Winter storm warnings and advisories span at least 14 states as a fast‑moving system delivers snow, freezing rain and gusts across the Midwest, Great Lakes and into the interior Northeast.
- Morning commutes turned slick in cities including Chicago, Detroit and Milwaukee with wind‑driven snow and 30–40 mph gusts lowering visibility; dozens of school delays and closures were reported in parts of Wisconsin and Michigan.
- Snowfall is highly localized: southeast Michigan logged roughly 1–7 inches by late morning, Wisconsin saw up to about 4 inches in spots, Pennsylvania advisories cite totals up to 14 inches, and New York’s Tug Hill/eastern Lake Ontario region is forecast for 8–16 inches.
- High terrain in the Rockies faces dangerous conditions with 60–80 mph ridge gusts and avalanche warnings in ranges including the Tetons and Gros Ventre, where travel over mountain passes is discouraged.
- A sharp temperature drop this afternoon and evening will freeze wet roads and produce single‑digit wind chills, with lake‑effect bands expected tonight into Thursday and forecasts calling for additional clippers later this week.
