Overview
- Light snow spreads Friday into Saturday with general totals of 1–3 inches and locally higher amounts where coastal or lake-effect enhancement develops, and brief snow squalls may snarl commutes.
- The Weather Prediction Center and NWS have issued Extreme Cold Warnings, Cold Weather Advisories and High Wind Warnings for wide areas, including Washington, D.C., Maryland and northern Virginia.
- Wind chills will plunge Saturday night into Sunday, reaching the minus-20s to minus-30s inland across the interior Northeast and New England, with dangerous frostbite and hypothermia risk.
- Gusts could exceed 50–60 mph in parts of the Appalachians, Mid-Atlantic and interior Northeast, raising the threat of isolated tree damage, power outages and difficult travel for high-profile vehicles.
- Great Lakes and Northeast communities may see additional lake- or ocean-enhanced snow in spots, and a gradual warming trend is forecast next week with many locations rebounding into the 30s to 50s.
