Severe thunderstorms likely to develop across the eastern Plains and Missouri Valley Wednesday afternoon and evening with large hail, damaging wind gusts and isolated tornadoes. Widespread heavy rains will also cause flooding across northeast Texas, northern Louisiana, southern Arkansas, southwest Tennessee, and north and central Mississippi.
Weaker thunderstorms and showers are developing Wednesday morning across northern Texas, eastern Oklahoma, northern Louisiana, and Arkansas. By the afternoon and evening, storms will begin to strengthen as the environment becomes more unstable and thunderstorms will develop ahead of the cold front in central Oklahoma and Kansas. Large hail and damaging wind gusts will be the primary threats across most of the region but isolated tornadoes are likely especially in northeast Texas, northern Louisiana, southern Arkansas, central Oklahoma, and eastern Kansas. Thunderstorms will also develop along the warm front in Iowa and northern Missouri with large hail and wind gusts being the primary threat, although an isolated tornado cannot be ruled out. Thunderstorms will generally move southwest to northeast, continuing into the evening hours before weakening overnight.
The surge of moisture from the Gulf will bring 2-5 inches of rain and locally higher amounts which will likely cause flooding in areas like Tyler, Shreveport, Jackson, Memphis and Little Rock. Rain will begin Wednesday morning and continue into early Thursday morning.
