Severe thunderstorms packing damaging winds, large hail and a few tornadoes are possible Tuesday across a wide area, from Texas to the Mississippi and Ohio Valleys.
An area of low pressure will slide eastward across the Midwest while its trailing cold front sweeps through the south-central states and a warm front lifts northward into the Ohio Valley.
At the same time, warm and moist air from the Gulf of Mexico will surge northward into much of the Deep South and the Tennessee and Ohio Valleys, providing the moisture needed for the formation of thunderstorms.
This is not expected to be a widespread outbreak of severe weather, but there could be a corridor across the Ohio Valley where a more concentrated swath of wind damage occurs. This may include parts of southern Illinois, southern Indiana, southwest Ohio, western/middle Kentucky and northwest Tennessee.
Below is our latest forecast thinking on the timing and magnitude of the severe threats on Tuesday.
Severe Weather Forecast
- Forecast: Severe thunderstorms are possible from mid-afternoon into early evening across a wide area, from east-central Texas northeastward to the lower and mid-Mississippi Valley, Tennessee Valley and Ohio Valley. Some severe storms could linger overnight from the upper Texas Coast into the lower Mississippi Valley.
- Threats: Damaging wind gusts and large hail are the main threats, although an isolated tornado or two cannot be ruled out.
- Cities: Houston | Little Rock | Memphis | Indianapolis | Cincinnati
There is a chance that a few severe storms may develop ahead of the cold front on Wednesday, from the coastal mid-Atlantic to north Florida. But this risk appears to be minimal at this time.
