Storms tonight have the potential to bring flash flooding, hail, frequent lightning strikes and locally damaging winds from central Texas to northern Mississippi and northwestern Alabama.
Motorists in the I-20, I-30 and I-40 corridors in the region can be hit with blinding downpours and excess water on the roadways. Flight delays are also possible.
While some of the rain is falling on needy drought areas, a large portion of the rain is falling on areas where ground moisture is high. This is why there is a risk of flash flooding in rural areas, as well as urban locations. Up to several inches of rain can fall, especially where the storms repeat.
As of the mid-afternoon, cloud cover over the warm sector of the storm area was greatly reducing the risk of the most violent storms.
Occasionally, severe thunderstorms, even in an average event, can produce a short-lived tornado.
Farther to the northeast over portions of the Ohio and Tennessee valleys, the risk of violent weather will pencil out. A tornado outbreak is not expected.
Drenching rain, flash flooding, locally gusty winds and thunder will occur in this area into the evening hours.
The zone of drenching rain and locally strong thunderstorms will shift southward later tonight and Friday, stretching from the Texas coast to the southern Appalachians and the North Carolina coast.
