Texas, Louisiana, Mississippi, Alabama, Georgia, and the Carolinas Face Life-Threatening Post-Storm Arctic Cold With Sub-Zero Wind Chills
UNITED STATES — After the winter storm exits the region, extremely dangerous Arctic cold is forecast to surge across the South by Monday morning, bringing single-digit wind chills as far south as the northern Gulf Coast and below-zero wind chills across inland areas, according to the latest temperature and wind-chill guidance.
Forecasters warn that this cold outbreak is not just uncomfortable, but potentially life-threatening, especially in areas already dealing with power outages from ice storm damage along and north of the I-20 corridor.
Wind Chill Breakdown by Region
The forecast wind-chill map shows a sharp and dangerous temperature gradient across the South:
- Sub-zero wind chills are expected across parts of Texas, Arkansas, Tennessee, and the Ohio Valley
- Single-digit wind chills (0s) extend across Mississippi, Alabama, northern Georgia, and parts of the Carolinas
- Wind chills in the teens (10s) spread farther south into central Alabama and Georgia
- 20s near the immediate Gulf Coast, where cold air still reaches unusually far south
Meteorologists emphasize that wind chill — not just air temperature — is the main threat, as strong cold advection following the storm will rapidly strip heat from exposed skin.
Why This Cold Is Especially Dangerous
This cold surge arrives immediately after a major winter storm, meaning many communities may still be dealing with:
- Downed power lines
- Extended power outages
- Limited access to heat
- Blocked or icy roadways
When wind chills fall into the single digits or below zero, frostbite can occur in 30 minutes or less, and hypothermia becomes a serious risk if indoor heating is unavailable.
Impacts Along the I-20 Corridor
Areas along and north of Interstate 20, including portions of Texas, Louisiana, Mississippi, Alabama, Georgia, and South Carolina, face heightened danger due to the combination of ice damage and extreme cold. Officials warn that loss of heat during these conditions could escalate quickly into an emergency, especially overnight.
What Residents Should Do Now
Preparation is critical before the weekend, not after the cold arrives:
- Protect pipes from freezing
- Bring pets indoors
- Check on elderly or vulnerable neighbors
- Charge devices and prepare backup heat safely
- Avoid unnecessary travel during the coldest period
This is not a typical Southern cold snap. Forecasters stress that this level of cold reaching this far south is rare, and the overlap with storm damage significantly increases the risk. As the Arctic air mass settles in Monday morning, conditions could become dangerous very quickly, even in areas that appear calm or dry.
