Huntsville, Alabama – A significant shift toward winter conditions is expected across northern Alabama beginning Thursday, as Arctic air pushes south and brings unusually cold temperatures, icy travel risks, and the potential for snow through the following Wednesday.
According to the National Weather Service Climate Prediction Center, northern Alabama is expected to experience a sustained period of below-normal temperatures during the Jan. 15–21 timeframe as a large Arctic air mass settles across the Tennessee Valley and Deep South. While overall precipitation is expected to remain near seasonal averages, the colder air will allow even light snowfall or freezing moisture to create hazardous conditions.
Communities across Madison, Limestone, Lauderdale, Colbert, Jackson, and Marshall counties are likely to see some of the coldest readings of the season. Overnight lows could fall into the teens, with wind chills dropping even lower during the late-night and early-morning hours. These conditions raise concerns for frozen pipes, stressed heating systems, and dangerous cold exposure for anyone outdoors for extended periods.
Travel impacts are possible if snow develops during the coldest portion of the pattern. Even light accumulations could lead to slick roads along Interstate 65, U.S. 72, U.S. 431, and secondary highways, especially during morning commute hours. Bridges and overpasses will be especially vulnerable to icing as temperatures remain below freezing for long stretches.
Farther east, areas near Scottsboro and Fort Payne could see slightly higher snow potential due to elevation, while northwest Alabama locations such as Florence and Muscle Shoals may see longer-lasting ice issues if cloud cover limits daytime warming.
Residents are urged to prepare by checking heating systems, insulating exposed plumbing, and stocking vehicles with winter emergency supplies. Limiting non-essential travel overnight and early in the morning may be necessary if icy conditions develop.
Cold-related advisories or winter weather alerts may be issued as confidence increases, with additional updates expected as the Arctic pattern becomes more firmly established across northern Alabama late next week.
