Severe thunderstorms are possible across all of Central Alabama this afternoon and evening. However, a watch severe thunderstorm watche issued earlier for Marengo County has expired as the stronger storms are now south of the county.

The severe risk comes as a prefrontal trough, ahead of the actual surface front, pushes southward into central parts of the state.

The severe threat will begin after noon in the north and then transition southward through the afternoon and evening hours. The threat should end by midnight.

About 11:30 a.m., the Birmingham National Weather Service issued a severe thunderstorm watch for Marengo and 24 other counties until 8 p.m. CDT. Those counties were Autauga, Barbour, Bibb, Bullock, Chambers, Chilton, Clay, Coosa, Dallas, Elmore, Greene, Hale, Lee, Lowndes, Macon, Marengo, Montgomery, Perry, Pike, Randolph, Russell, Shelby, Sumter, Talladega, Tallapoosa.

The watch has been allowed to expire in several of those counties in north central Alabama.

The main threats will be damaging straight line winds with locally heavy rainfall and frequent cloud to ground lightning.
