Overview
- Subzero or near‑zero wind chills persist through Saturday across much of the East, with Cold Weather and First Alert advisories posted in the New York area.
- Light, timing‑sensitive snow or flurries are possible Thursday from the Plains into the Midwest, with most spots seeing a dusting to about a half‑inch.
- A coastal low is expected to form off the Southeast Saturday evening and rapidly deepen into Sunday, with impacts most likely Sunday into Sunday night and tapering early Monday.
- Most model guidance trends the system offshore, yet a 50–100 mile track shift could bring heavier snow, 50–60 mph gusts and coastal flooding to southeastern Massachusetts.
- Maine and New Hampshire outlets now favor a glancing blow, though light coastal snow, high surf and minor flooding remain possible if the storm passes closer.
