Overview
- Post-storm travel remained snarled Saturday with more than 3,700 U.S. flight delays and nearly 800 cancellations as snow- and ice-covered roads slowed cleanup across the Northeast.
- Forecasters flagged a Sunday night to early Monday freezing rain threat for the Tri-State and parts of New England, with CBS New York noting a First Alert Weather Day and a Winter Weather Advisory for Sullivan, Ulster, Dutchess, Orange, Rockland, Putnam and Sussex counties.
- Across the Midwest, rain Sunday will give way to a fast-hitting cold front early Monday that brings 45–55 mph gusts, a rapid temperature plunge and flash-freeze hazards, with Detroit-area forecasters warning of scattered power outages.
- Heavy snow is expected in the Upper Midwest and Great Lakes with 5–14 inches in spots and blizzard conditions possible, while localized lake-effect bands could top 18 inches and plowable snow is likely downwind of Lakes Erie and Ontario into Tuesday.
- Longer-range guidance from AccuWeather and the National Weather Service points to a broader Arctic push Jan. 1–5 that keeps temperatures below average across the northern U.S.
