Overview
- Blizzard warnings stretch from the Upper Midwest into Michigan’s Upper Peninsula, including Marquette and Alger counties, where gusts may reach 60 mph and the National Weather Service has warned of whiteouts and discouraged travel.
- Freezing rain targets interior sections of the Northeast this evening into Monday, with a glaze common and up to about 0.5 inches possible in parts of northern New England, raising risks for slick roads and localized power outages.
- Air travel is already disrupted, with more than 3,500 delays and over 400 cancellations reported by midday Sunday, according to FlightAware data cited by national outlets.
- Nearly 40 million people are under winter alerts as the storm spreads snow, rain and strong winds; separate severe weather is possible from the Midwest into the Mid-South with damaging wind gusts and isolated tornado risk.
- The system is expected to weaken or move offshore by Monday night, followed by lake-effect snow downwind of the Great Lakes and an arctic surge that may trigger flash freezes and difficult Tuesday commutes.
