...DISCUSSION...

A return of deep convection remains likely on D4-5/Friday-Saturday

across the Gulf Coast States from LA to north FL, and into the Deep

South. A low-amplitude shortwave impulse should emanate out of the

Southwest and may briefly amplify on D4/Friday over TX, as it

becomes absorbed within the broader cyclonic flow regime across

eastern North America. Latest guidance has decidedly trended towards

dampening this impulse and attendant surface cyclone reflection as

they progress across the Gulf Coast States/northern Gulf Friday

night into Saturday. This combined with predominately westerly

low-level wind profiles may support only a marginal severe threat.

After this minor wave, severe potential appears negligible in the

D6-8 time frame.
