Tornadoes, Damaging Winds and Large Hail Threaten South as Flooding Rain Takes Aim at Ohio Valley

A dangerous threat of severe thunderstorms will produce tornadoes, large hail, wind damage and flooding rain in the South and Ohio Valley as the week comes to a close.

Severe weather will begin in the Southern Plains Thursday and Thursday night. Severe thunderstorms are most likely to develop from central Oklahoma into northern and west-central parts of Texas. An isolated severe storm threat could extend as far northeast as the mid-Mississippi Valley. Large hail and damaging winds are the main threats, however an isolated tornado is possible.

The threat will peak in the South on Friday and Friday night. A higher-end severe storm threat appears likely, especially in the lower Mississippi Valley beginning in the afternoon, including Shreveport and Monroe, Louisiana; Greenville and Jackson, Mississippi; Memphis, Tennessee and Little Rock, Arkansas.

These areas could see supercell thunderstorms that are capable of producing tornadoes, large hail and wind damage. This might include the possibility of strong tornadoes (EF2 or greater strength).

Then, a squall line of severe storms could produce wind damage and isolated tornadoes as it spreads farther east late in the evening into the overnight hours, including as far east as parts of Alabama, middle Tennessee, central Kentucky and possibly northwest Georgia.

Inches of rain could cause flooding. The setup is also one that can wring out heavy rain in a short amount of time. Multi-inch rainfall totals are possible from the Ohio Valley into the mid-Mississippi Valley and mid-South through Friday night.

As a result, the National Weather Service has issued flood watches from the eastern half of Oklahoma to the Ohio Valley. This is where flash flooding and minor to moderate river flooding is possible.

We recognize the severe impact that current conditions are having on our customers, and we are committed to restoring service levels as quickly as possible. As a result of these weather issues, the ALG Client Service Team will send daily updates as we monitor the progress and track job level impact.
