Hybrid Winter Storm Threatens Midweek Snow From Tennessee Valley to Northeast

Overview

• A fast-moving clipper now in Canada is forecast to reach the Great Lakes on Tuesday, with its southbound cold front producing mainly rain across the Midwest and Ohio Valley.
• A weaker disturbance will brush New England with light snow Monday before the main front stalls Tuesday night into Wednesday.
• A new low is likely to consolidate over the Appalachians Wednesday night as the pattern transitions toward a broader East Coast event through Friday.
• Meteorologists describe a hybrid setup with no single dominant surface low early, complicating snowfall projections and shifting rain–snow lines.
• Key uncertainties—cold-air arrival, moisture, and track—leave late-week I‑95 snowfall possible but unconfirmed, while confidence is higher for heavy upslope snow in the southern Appalachians and for lake-effect bands near the Great Lakes, including near Chicago or South Bend.
