The threat of severe weather continues east of Wednesday's devastation in Granbury, Texas. Northeastern Texas and Louisiana are at risk for damaging storms.

Update at 3:15 p.m. CDT Thursday: One-inch diameter hail has damaged vehicles and a funnel cloud has been spotted in Shreveport, La. A storm was showing signs of a possible tornado south of the town.

With these storms, the main threat will be damaging wind gusts and hail. However, there still remains a threat of an isolated tornado. But as AccuWeather Staff Writer Samantha-Rae Tuthill explains, it only takes one tornado to cause devastation.

The upper-level low pressure that created the deadly tornadoes in northern Texas on Wednesday evening is moving eastward, acting as a trigger.

The hot temperatures from western Texas will continue to combine with the Gulf of Mexico moisture creating a clash favorable for strong thunderstorms.

While the exact storm complex that brought Wednesday's tornadoes began to decay late into the morning Thursday, the threat will ramp up again in far eastern Texas, southern Arkansas and the northern half of Louisiana.

Thunderstorms will be spotty, but likely strongest and most numerous in the afternoon and evening, after daytime heating will be able to help storms develop.

The possibility for severe weather is not limited to the southern Plains Thursday. Another upper low emerging from Colorado could also produce severe weather in the central Plains during the afternoon.
