Overview
- Federal guidance indicates a strong Arctic front will advance across the central and eastern U.S. early next week, with the coldest surge expected Sunday into Monday.
- Temperatures are forecast to drop sharply, with highs in the 30s and 40s across parts of the Upper Midwest and Great Lakes and subfreezing lows possible into the Central Plains and Tennessee Valley.
- The Climate Prediction Center notes elevated chances for interior Northeast and lake-effect snow, with a slight risk for heavier snow bands Nov. 11–13 downwind of Lakes Erie and Ontario.
- AccuWeather and local NWS outlooks signal potential first frosts or freezes in sections of the Southeast, threatening to end the growing season in areas of Mississippi, Georgia, and northern Florida.
- Forecasters also project a sharp East–West contrast as strong ridging keeps the West unusually warm by about 10–15 degrees above average, and milder air is expected to return to the East by midweek.
