Local weather guy out of New Orleans (Bob Breck Fox-8-) said that a front should pick it up and head it towards the Central Florida peninsula.
Most models I have seen , so far, verify his forecast.
Don't need any more rain in south Louisiana, my yard is just starting to dry up.
From the Gulf of Mexico Satellite Site:
From this image, it appears the bulk of the rain is Southwest of the mouth of the Mississippi River.
This morning there was much more rain off the Mississippi and Alabama Gulf Coasts.
It just may be the circular motion of this system that is causing it.
Hopefully, this system is headed South and not North...
