The National Weather Service office in Corpus Christi has issued a severe thunderstorm warning for South Texas.

The storm is expected to push off the coast by midnight with the threat of large hail and damaging winds continuing into the Gulf waters.  Rainfall amounts of one-quarter to one-half inch will be possible across the South Texas area, with isolated amounts up to one inch or more possible with the stronger storms.

“Although the atmosphere is expected to become very unstable, a moderate to strong cap still resides over the Coastal Bend region. If the cap does not break, storms would tend to weaken as they approached the coast,” said John Metz, warning Coordination meteorologist with the National Weather Service.

A cold front will move through the area in the wake of the storms, moving offshore after midnight.  Cooler conditions will prevail on Wednesday.  However, scattered showers and isolated thunderstorms will still be possible behind the front through the day on Wednesday.  These storms on Wednesday have the potential to produce small hail, Metz said.
