NASHVILLE, TENNESSEE — The Storm Prediction Center has increased the probability of severe weather Sunday night, raising portions of Middle Tennessee and northern Alabama to a 30 percent chance of severe storms within 25 miles of any given point — a notable escalation in concern as a powerful storm system approaches.
The updated outlook highlights a growing damaging wind threat, with forecasters warning that straight-line wind damage could become both significant and widespread.
30 Percent Severe Probability Now in Place
The expanded 30 percent zone now includes:
- Nashville
- Clarksville
- Bowling Green
- Franklin
- Murfreesboro
- Columbia
- Shelbyville
- Huntsville
- Hartselle
The hatched overlay across parts of this region indicates the potential for enhanced wind intensity — meaning damaging gusts could be severe enough to cause widespread tree damage, structural impacts and power outages.
Forecasters emphasize that the primary hazard appears to be straight-line winds rather than large hail or discrete supercell tornadoes, though brief embedded tornadoes cannot be ruled out.
