Thunderstorms from South Texas into the Lower Mississippi Valley on Wednesday
Scattered thunderstorms are forecast to continue developing along and ahead of a slow moving cold front. Plentiful low-level moisture and daytime heating will allow instability to build this afternoon. Conditions will be favorable for the development of severe thunderstorms capable of producing large hail, damaging winds, and tornadoes. Later tonight, storms could congeal into a squall line that may impact southeast Texas and Louisiana. Damaging winds will then become the primary hazard.
