Reply to Doug's post: Analysis over your area reveal a sharp shortwave trough in the upper levels and may cutoff. Upper ridge to it's south. I think what you're looking at is the result of the old surface front washing out now as a surface trough and upper level difluence supporting thunderstorms in your area. You do make a good point in that old fronts are spawning grounds for tropical lows, and while shear aloft is quite low over the eastern GOM it can't be ruled out. If convection persists it will require being watched. Forecast shear analysis has that are becoming hostile in 72 hours unless something does form and it gets itself in the Atlantic; the GOM will once again become too hostile to sustain tropical activity except shallow activity.
