Overview
- Showers develop Wednesday before colder air changes precipitation to snow or flurries Wednesday night into Thursday from the Great Lakes through the Ohio Valley and Mid-Atlantic, with New England seeing mainly showers before a late‑week cool‑down.
- Temperatures tumble behind the front, with highs dropping into the 20s in many spots and wind chills near or below zero in parts of the Great Lakes and Northeast.
- Most locations are projected to see little to no accumulation with marginal surface temperatures, but localized 2–4 inches are possible north of I‑80 and multi‑inch lake‑effect bands may focus in Northwest Indiana.
- In metro Detroit, snow totals around 1 inch are possible with 2–3 inches near Lake Huron as lake‑effect snow lingers into Wednesday night.
- In the Southeast, northeast Alabama most likely gets cold rain ending as flurries, though a less‑likely model scenario shows up to roughly a half‑inch; along the Gulf Coast, successive fronts bring cooler snaps without a widespread deep freeze.
