There will be two rounds of potential severe storms on Sunday, with the greatest chance being cross the central and southern portions of our coverage area. Currently, north Alabama and southern Middle Tennessee have a low/marginal threat, meaning the threats are less likely but cannot be ruled out.
Round 1: 4am to 11am
The first round will be from 4am to 11am, with damaging winds and hail the primary threats. The greatest chance with this round will be along and south of a line from Millport to Birmingham to Anniston.

The second round of severe storms will be from 2pm to midnight, with tornadoes, damaging winds, and hail all possible. There is a moderate risk for portions of Bibb, Chilton, extreme southern Pickens, and extreme southern Tuscaloosa counties. A few strong tornadoes are possible in this area.
