NOAA's Storm Prediction Center has issued the following severe weather watches:
- A severe thunderstorm watch valid until 11 p.m. CDT for portions of southern Indiana, central Kentucky and middle Tennessee. This watch area includes Louisville, Kentucky, and Bowling Green, Kentucky.
- A severe thunderstorm watch valid until 9 p.m. CDT for parts of south-central Texas. This watch area includes Laredo, Texas.
In addition to the risk of severe storms, locally heavy rainfall will bring the risk of flash flooding through Saturday night from Texas into the South and portions of the Midwest.
Current Radar, Watches and Warnings
Early Saturday evening, a brief tornado was reported to have touched down in parts of Newton, Jasper, Benton and White counties in northwest Indiana.
Additionally, hail up to 2.50 inches in diameter was reported in the city of Rush, Kentucky, Saturday afternoon.
Friday night into Saturday morning, flash flooding was reported in portions of Oklahoma and southern Missouri. In Reagan and Pontotoc, Oklahoma, homes were evacuated due to flooding, and in Krebs, Oklahoma, water reached the doorways of homes.
The risk of severe thunderstorms and heavy rain is courtesy of an area of low pressure that is expected to slowly push into the East by Monday. Ahead of this system there will be plenty of moisture and moderate instability, which will likely allow a few severe storms to develop.
For a recap of this week's severe weather, scroll down to our recap section. Now, let's check out the forecast for more severe weather ahead.
Through Saturday Evening
- Forecast: Scattered severe thunderstorms are possible from portions of the southern Great Lakes and Ohio Valley southward into middle Tennessee, Alabama, Mississippi and Louisiana. A few severe thunderstorms are also possible in portions of southern and central Texas.
- Threats: Damaging winds and large hail are the main threats, but an isolated tornado is also possible.
- Cities: Louisville | Nashville | Birmingham
Thunderstorm Forecast Through Saturday Evening
A few strong to severe thunderstorms cannot be ruled out on Sunday, mainly from the northern Gulf Coast into southern Texas.
Heavy Rain Threat
These repeated rounds of thunderstorms this week, and previously saturated ground from record flooding in late April and early May, is setting the stage for a threat of local flash flooding and river flooding.
Some locations from central Texas into the Ohio Valley and Southeast should see at least 1 to 3 inches of rain through this weekend, with locally higher amounts where thunderstorm clusters or lines stall.
This additional heavy rain on top of already saturated ground may trigger localized flash flooding.
A flash flood watch remains in effect for portions of southern Mississippi and southeastern Louisiana.
