Frost Advisory Covers North Alabama Counties
The National Weather Service Huntsville forecast brings frost overnight Sunday and a chance of rain later in the week across the Tennessee Valley.
Updated on Nov. 8, 2026 in Forecasts
A frost advisory is in effect across northern Alabama until 7 AM CST Sunday, covering Madison, Lauderdale, Colbert, Franklin, Lawrence, Limestone, Morgan, Cullman, Marshall, Jackson, and DeKalb counties. The National Weather Service Huntsville zone forecast calls for patchy frost after midnight Sunday in Madison County.
Why it matters
Frost during the overnight period can damage sensitive plants and exposed crops, so the advisory signals the first cold stretch of the season for the region. Forecasters expect temperatures to rebound before a cooler, wetter pattern arrives later in the week.
The figures come from the National Weather Service Huntsville zone forecast, which lists Madison County highs in the mid 60s Sunday and a 40 percent chance of rain Wednesday night. Forecasters have not indicated how much rain may fall or whether frost will be uniform across all eleven advisory counties.
The players
National Weather Service Huntsville
The National Weather Service office in Huntsville, Alabama, issues forecasts and warnings for the Tennessee Valley, including northern Alabama.
The details
The advisory covers eleven northern Alabama counties through 7 AM CST Sunday, and the zone forecast lists Madison County highs around 70 from Tuesday through Veterans Day. Lows drop to the upper 30s Thursday night and around 30 Friday and Saturday, with highs in the mid 50s Friday through Saturday.
Timeline
Sunday, November 8, 2026: frost advisory expires at 7 AM CST, with mostly sunny skies and highs in the mid 60s.
Sunday night, November 8, 2026: clear skies with patchy frost forming after midnight.
Wednesday night, November 11, 2026: 40 percent chance of showers in Madison County.
Thursday night, November 12, 2026: cooler temperatures with lows in the upper 30s.
Friday through Saturday, November 13 to 14, 2026: highs in the mid 50s and lows near 30.
Seasonal Patterns
The forecast follows the standard zone-based product the National Weather Service Huntsville uses for the Tennessee Valley, placing an early November frost advisory in line with typical autumn cold-air intrusions for the region. Overnight lows near 30 later in the week fit the cooling pattern that usually follows the first frost of the season in north Alabama.
Residents with tender plants should cover or bring them indoors before Sunday night, when patchy frost is forecast after midnight in Madison County. Those planning outdoor activities should expect highs in the mid 60s Sunday and a higher chance of rain Wednesday night.
The takeaway
Protect sensitive plants before Sunday night and keep an eye on the Wednesday rain chance before planning outdoor work. Cooler temperatures return by Thursday, so plan for lows in the upper 30s and near 30 later in the week.
