Severe Weather Update - Lower Mississippi Valley Region...

The above radar composite was taken just a few moments ago, and shows a large complex of shower and thunderstorm activity from southeast Texas into much of Louisiana and southern Arkansas.  This activity is generally moving toward the East/Northeast at about 20-25 mph.

Very heavy rainfall, gusty winds and marginally severe hail appear to be the main severe threats with the activity at this time.  

The southern most portion of the complex has the greatest chance of reaching severe levels during the next few hours, over far southeast Texas and southern Louisiana, where the air is more unstable.  Otherwise, locally heavy rainfall of up to 2 inches per hour in some areas appears to be the most significant threat (other than frequent cloud to ground lightning).

Folks living across the region from southeast Texas, including the Houston, Galveston and Port Arthur areas, should remain alert this evening and be prepared to seek shelter if threatening weather approaches.
