An enhanced risk — Level 3 of 5 — for severe storms is forecast 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.
“Scattered severe storms are likely, mainly during the afternoon into early evening across parts of central to east Texas through the Mid-South. Damaging winds should be the primary hazard, but isolated tornadoes and large hail will also be possible,” the prediction center said.
A tornado watch is in effect until 6 p.m. CDT for parts of northeast and central Texas, southwest Arkansas and northwest Louisiana. Nearly six million people are in the watch area that includes Austin, Waco and Tyler in Texas and Shreveport, Louisiana.
A severe thunderstorm watch has been issued to the east of the tornado watch for southeast Arkansas, northern Mississippi and southwest Tennessee. This watch is in effect until 8 p.m. CDT and includes Memphis. While tornadoes can’t be ruled out in this area, wind and hail will present the biggest threat.
“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.
