Tuscaloosa, Alabama – A push of Arctic air is expected to influence communities along the Mississippi–Alabama border between Jan. 18 and Jan. 22, bringing a turn toward cooler conditions as a fast-moving clipper system reinforces a broader pattern shift across the central and eastern United States.
According to the Climate Prediction Center’s 6–10 day temperature outlook, the Mississippi–Alabama border region falls within an area showing a 40% to 60% probability of below-normal temperatures during this period. This reflects moderate confidence in colder-than-average conditions, though the signal is weaker than across parts of the Ohio Valley and Appalachians. The evolving pattern is driven by ridging across the western U.S. and Alaska, allowing cooler Arctic air to press southeastward into the Deep South.
Daytime high temperatures are expected to trend a few degrees below mid-January averages at times, while overnight lows dip more noticeably during clear periods. Increasing northwest winds behind the clipper system may add a sharper chill, particularly during overnight and early morning hours for commuters, students, and outdoor workers.
Through Jan. 22, precipitation chances are expected to remain near normal for this time of year. Forecast guidance does not indicate a strong signal for widespread rain or winter precipitation during the core cold window, as the incoming air mass is expected to be relatively dry. Any precipitation that does occur would likely be light and brief, associated with fast-moving systems.
For residents along the Mississippi–Alabama border, including communities from northeastern Mississippi into western Alabama, the primary impacts during this period will be cooler daytime temperatures, colder nights, and increased heating demand, rather than significant winter weather disruptions. Forecast updates are expected as temperature trends and wind impacts become clearer later this week.
