Overview
- National Weather Service offices have issued advisories and warnings for late Wednesday into early Thursday as gusts peak between 45 and 60 mph, posing risks of downed trees and power outages.
- Officials flag elevated fire weather concerns in parts of the Mid‑Atlantic where strong winds, low humidity and dry fuels coincide, and outdoor burning is discouraged.
- Arctic air is projected to spill south Sunday into early next week across the Great Lakes, Ohio Valley, Northeast and parts of the Southeast, with temperatures running roughly 10–20°F below average.
- Light to moderate snow is possible for some areas beginning Sunday, and cold air over the relatively warm Great Lakes could enhance localized lake‑effect snow east and southeast of Lakes Michigan, Erie and Ontario.
- Forecast models show storm‑track uncertainty with a southward trend that could keep some northern fringe locations mostly dry, and forecasters expect the cold snap to be short‑lived with milder air returning by midweek.
