..there is a marginal risk of severe thunderstorms from southeast 
Texas into western Louisiana... 


... 
Thunderstorms are expected from the Southern Plains into the lower 
Mississippi Valley region Friday. A low probability of locally 
strong wind gusts will exist from southeast Texas into western 
Louisiana during the day. 


..southeast Texas into western Louisiana... 


Thunderstorms will likely be ongoing along a cold front as well as 
in pre-frontal confluent zone within a moist (70f dewpoints) but 
marginally unstable boundary layer. This activity will be embedded 
within strong vertical shear associated with a progressive synoptic 
southern-stream trough. Storms developing in pre-frontal confluent 
zone should be surface based or only slightly elevated, and might 
become capable of producing a couple of locally strong wind gusts 
during the day. The weak thermodynamic environment should remain a 
limiting factor.
