Forecast Models Show Overnight Lows in the Teens and 20s Across Alabama, Mississippi, Georgia, and Tennessee Next Weekend as Arctic Surge Approaches

SOUTHEAST UNITED STATES — Long-range data continues to support a significant Arctic surge targeting Alabama, Mississippi, Georgia, and Tennessee next weekend, with projected overnight lows falling into the teens and 20s and the potential for single-digit wind chills early Saturday, December 13. If current trends hold, this could be the coldest air mass so far this season for the region.

Temperatures Expected to Plunge Deep Into the Teens and 20s

The latest GFS forecast shows a widespread drop in temperatures across the Southeast, with early-morning lows on December 13 reaching the mid-to-upper teens across northern Alabama and Tennessee. Areas across central Mississippi, central Alabama, and northern Georgia are projected to settle into the 20–25°F range, while even southern counties across the region could fall into the upper 20s and low 30s.

Forecasters caution that these values reflect actual air temperatures, not wind chills. With northerly winds expected behind the front, the feels-like values may drop considerably lower, especially in elevated or exposed areas. The consistency in recent model runs increases confidence that a sharp cold blast is likely.

Possible Single-Digit Wind Chills in Northern Alabama and Tennessee

While the magnitude of wind speeds will determine just how extreme conditions become, current projections show the possibility of wind chills dipping into the single digits across parts of Huntsville, The Shoals, northern Mississippi, and central Tennessee. Such low apparent temperatures pose risks for outdoor workers, unprotected pets, and sensitive plumbing.

Meteorologists also note that although the cold surge appears intense, it may be short-lived, with temperatures recovering gradually early the following week. Still, even a brief freeze of this depth can create disruptions across a region unaccustomed to Arctic-level wind chills.

Residents Should Prepare for a Hard Freeze Across Multiple States

With temperatures this low, preparations should begin soon. Residents in Alabama, Mississippi, Georgia, and Tennessee are advised to insulate exposed pipes, safeguard outdoor animals, and check heating systems to ensure safe operation during the coldest hours.

Agricultural impacts are also possible, especially in areas expecting temperatures below 20°F, which can damage plants and crops not tolerant to extreme cold.

Forecasters emphasize that while exact numbers may shift with newer data, the overall cold signal remains strong and is unlikely to be reversed.
