For those that are a little confused at what they are looking at....
The "slow circulation" you are observing is an UPPER LEVEL LOW, that MAY work its way to the surface sometime Saturday through Monday.
The surface low pressure observations are a result of a surface TROUGH, that if the upper level low moves to the surface, could develop under more favorable conditions Sunday through Tuesday.
Current movement: Slowly Westward at 5-10 MPH.

It is as long as a surface (less likely, ~19%) or an upper level high (more likely (~74%) develops...because technically, a low pressure cannot exist for long at both the surface and the upper levels as converging air results in a pileup of air around the center. Also, it is possible for it to still go west into the GOM if when an upper high develops, the surface is a weak open wave or a very very weak LLC.
