Reply to Lamar in Plant City - I commented on this earlier but it was this morning. At 250mb and 300mb (35,000 and 30,000 feet) there is a sharp shortwave that is very close to being cutoff. Thunderstorm activity is on the east side of the feature thus explains the slow northward drift. The area has very low wind shear aloft but is forecasted to become hostile in 48 to 72 hours so unless this feature moves over the Atlantic it won't survive in the GOM. Yes, there is an old frontal boundary in the area, a place for convergence at the surface and difluence aloft supporting vertical rise. If there's something there, the environment for the short term is conducive, but hostile thereafter, I hope this helps.
