Huntsville, Alabama – Arctic air is expected to remain positioned mainly north of Alabama late this month, with only limited and short-lived influence possible across northern portions of the state from Jan. 24 through Jan. 30.
According to the National Weather Service Climate Prediction Center, northern Alabama falls within a roughly 40 percent probability zone for below-normal temperatures during the Jan. 24–30 period. This places the region on the southern fringe of the broader Arctic pattern, where brief cool shots are possible but prolonged cold is not favored.
Across the Tennessee Valley, including Huntsville, Decatur, and the Interstate 565 corridor, daytime highs may dip slightly below late-January averages at times, but are expected to rebound during milder stretches. Overnight lows could fall into the upper 20s and 30s on colder nights, allowing for patchy frost and isolated slick spots on bridges and elevated roadways during early morning hours.
Farther east toward Scottsboro and the foothills near the Cumberland Plateau, cooler air may linger a bit longer overnight, though daytime recovery should limit overall impacts. Areas farther south toward Birmingham are likely to see even less influence from Arctic air.
The Alabama Department of Transportation advises drivers to remain alert for isolated early morning slick spots during brief cold spells, especially in rural and elevated areas. Overall, confidence remains low that below-normal temperatures will dominate northern Alabama through the end of the month, with the prevailing pattern favoring variable but generally seasonable late-January conditions.
