Overview
- Forecasters expect the low to deepen fast enough between Sunday and Monday to meet the bomb‑cyclone benchmark of a 24‑millibar drop in 24 hours under NOAA’s definition.
- Model guidance tracks the center from near Omaha–Minneapolis Sunday morning to Green Bay–Chicago by evening, peaking over Lake Huron and North Bay Monday morning before pushing toward Ottawa and the Northeast.
- The National Weather Service has posted winter storm, blizzard and high‑wind alerts across the Midwest and Great Lakes, with Michigan’s Upper Peninsula expecting blizzard conditions and gusts to 65 mph and parts of upstate New York forecast to see up to 3 feet of lake‑effect snow through late week.
- Travel was already snarled in the New York region on Sunday as freezing rain contributed to more than 1,000 flight delays across LaGuardia, JFK and Newark.
- AccuWeather and local outlets warn of a broad hazard footprint fueled by Gulf moisture, including heavy snow, freezing rain, severe thunderstorms and damaging winds capable of power outages and hazardous roads across more than two dozen states.
