An enhanced risk — Level 3 of 5 — for severe storms is forecast Thursday across east Texas, southern Arkansas and northwest Louisiana, including Shreveport.
“Damaging wind, hail and a few tornadoes are expected,” the Storm Prediction Center stated.
A slight risk — Level 2 of 5 — surrounds the enhanced risk area and covers nearly 10 million people, including in Dallas and Austin in Texas and Memphis, Tennessee. The same severe impacts threaten these places but with a slightly lower probability of dangerous conditions than those in the enhanced risk zone.
“Uncertainty remains regarding convective evolution through the day,” the prediction center said.
Early-day storms may persist and intensify through Thursday morning, then diminish and redevelop in the afternoon from Texas through Arkansas, with extreme winds and a few tornadoes possible.
“In addition, heavy rain will be associated with these thunderstorms,” the prediction center said.
This could lead to flash flooding, especially in urban areas and along small streams. Flash flood watches are posted in parts of Oklahoma, Kansas, Missouri and Arkansas through Thursday evening.
