EM – Severe hail threats in South Texas

Instability and moisture continue to develop along an established stationary boundary across deep South Texas and the Mississippi River Valley.

On Sunday, there is a chance of scattered severe thunderstorms developing during the day along the I-10 and I-35 corridors.

Hail is going to be the biggest threat with the possibility of hail the size of an egg or larger in isolated thunderstorms that develop.

These thunderstorms will be driven primarily by daytime heating and will collapse overnight.

Frequent hail and lightning will continue as these thunderstorms move near major subways in San Antonio and Austin.

After sunset, the last bit of energy will be exhausted and we will see most activity end by midnight.
