Overview
- Cold air arrives Sunday into Monday with temperatures 10–20°F below normal from the Upper Midwest through the Ohio Valley and Northeast, reaching parts of the Southeast by early next week.
- Lake-effect bands downwind of the Great Lakes and occasional interior Northeast snow are possible, with the Climate Prediction Center posting a slight risk for heavy snow Nov. 11–13.
- Winds around the frontal passages will be a key hazard, with widespread gusts of 30–40 mph and localized 50–60 mph prompting advisories and raising risks of downed trees and power outages.
- Forecast confidence on precipitation placement is still evolving, with some model trends shifting south and implying sharp gradients in who sees rain, a mix, or light accumulations.
- Agricultural impacts are likely where first freezes end the growing season in parts of the East and frost threatens sensitive vegetation in the Southeast, even as the West stays unusually warm.
