Gulf of Mexico

I know it's not expected to develop into anything, but man, the GOM is FULL of moisture!!!

The Gulf of Mexico is indeed full of moisture. There has been tropical development from this sort of feature (a trough axis) in the past.

I am not too sure when the last system to develop from this setup was and what the name of the system was.

That is part of a trough that streches from Texas to the coast of the panhandle of Florida but no surface low is in the GOM that could start anything.A surface low is inland near San Antonio.

As was mentioned in another thread in this forum... Garrett mentioned that Dr. Steve Lyons said that the upper level low (ULL) moving toward the Gulf of Mexico from the western Caribbean can assist in developing a surface low somewhere in the Gulf of Mexico.

At the moment, I do not see a surface low pressure system near San Antonio, Texas. If one is developing and it moves southeastward into the Gulf of Mexico things may become more interesting.

After all, we need a surface low pressure system over warm sea surface temperatures and low upper level winds for a decent chance for tropical cyclogenesis.

The low that Dr. Lyons was talking about is an ULL currently over Cuba with an accompanying trough. Indeed as Luis said what you are seeing in the N GOM is leftovers from TS Bill. It is low level trough with no tropical characteristics or low pressure associated with it and no development is expected from it. If anything were to develop over the next several days it will either be from the 93L invest which is beginning to cross the Windward Islands or from the ULL mentioned above.
