Overview
- Saturday's storm delivered 6–8 inches across the Chicago area, with foot‑plus totals in parts of Iowa, after the National Weather Service issued widespread winter alerts from Montana to Ohio.
- The FAA imposed ground stops at O'Hare and Midway, and FlightAware logged over 1,200 cancellations at O'Hare and more than 200 at Midway on Saturday, with delays continuing into Sunday.
- Dangerous road conditions led to multiple crashes, including an approximately 45‑vehicle pileup on I‑70 near Terre Haute, as visibility and traction deteriorated.
- Lake‑effect bands and gusty northwest winds produced localized bursts and blowing snow across the Great Lakes, adding 1–2 inches in typical snowbelts and complicating cleanup.
- Forecasters are tracking a coastal low Tuesday for the Mid‑Atlantic and New England, with rain near the shoreline, a wintry mix or plowable snow inland, and winter storm watches posted in parts of New Hampshire.
