Last week a number of the non tropical models were forecasting a Low to develop in the NE GOM.
Reading the morning AFDs around my area they are sticking with the development of a Low and vary greatly with how developed it will become. Jackson,MS NWS is forecasting it to move inland Thursday.

Slidell,LA NWS has no mention of the system. And Mobile,AL's excerpt follows:

ECMWF HAS BEEN FLIP-FLOPPING IN DEVELOPING LOW
PRESSURE ALONG THE OLD BOUNDARY OVER THE PAST SEVERAL DAYS...AND IS
NOW ADVERTISING A LOW THAT DEVELOPS SOUTH OF LOUISIANA EARLY THURSDAY
AND MOVES INTO THE SABINE PASS REGION LATE FRIDAY.

It appears that yet another round of thunderstorms are forecast to help clean up the GOM Oil Spill areas.
