Flood and severe threat pushes into mid-Atlantic, Southeast

A front stretched from the Carolinas through Texas will keep afternoon thunderstorms firing into midweek. The focus of the flooding shifts to the mid-Atlantic while a strengthening low puts the risk of thunderstorms, wind and hail over the Tennessee Valley and Carolinas.

Days of relentless rain have led to flash flooding across South Texas, including the San Antonio area, where first responders conducted several swift-water rescues over Mother's Day weekend. River flooding remains a concern in Texas while the threat of widespread flooding and severe weather shifts to the Heartland and Southeast.

RELENTLESS RAIN PROMPTS FLASH FLOODING THREAT IN SOUTH, MID-MISSISSIPPI VALLEY

Heavy rain led to flooding issues across the St. Louis metro on Sunday night, prompting Flash Flood Warnings for the area. Video from the area showed cars stuck under an overpass when heavy rain resulted in flash flooding.

Texas high water rescues continued Tuesday. The Texas A&M Task Force 1 alone rescued five people, three horses, two cows, three doves and 68 goats.

HERE'S WHAT TO DO IF YOUR CAR IS FLOODED

Overnight and Tuesday threat

The FOX Forecast Center said flash flooding is likely across portions of the central and southern Plains and the mid-Mississippi Valley..

A west-to-east oriented cold front will drop south into southern Missouri and northern Arkansas. As it does, the steady influx of moisture and increasing instability in the atmosphere should raise the risk of heavy rain that could lead to flooding.

Based on the latest data from computer forecast models, the FOX Forecast Center believes the greatest risk will be centered across eastern Oklahoma and the Ozarks in Missouri.

A low pressure system organizing along the front in the Tennessee Valley creates a likely threat across Kentucky, Tennessee, North Carolina and Virginia.

"The strongest storms will be capable of hail and damaging wind gusts, as well as frequent lighting," said the FOX Forecast Center. "The tornado threat will be very low with these storms."
