The way it looks right now, most of the moisture is off the coast and to the south of Cent. Fl. As the ULL keeps pinwheeling n/nw it will draw more of that moisture towards Fl. and produce showers. Eventually though it will move far enough north to where the showers aren't affecting Fl. as much, probably starting on Sunday.

Edit-The 2pm Trop. Disc. answered your question about the rain Colleen:

"THE UPPER TROF IS CURRENTLY SPREADING DRY AIR IN FROM THE W OVER S FLORIDA AND THE NW BAHAMAS WHICH HAS KEPT THE HEAVIEST TSTMS MAINLY TO THE E OVER OPEN WATERS. THIS AREA OF HEAVY RAIN/TSTMS WILL APPROACH AND SPREAD OVER THE SOUTHEAST U.S. COAST LATER TONIGHT AND ON SAT...AND THEN A SECOND SURGE OF MOISTURE IS EXPECTED TO MOVE FROM THE BAHAMAS TO S/CNTRL FLORIDA ON SUN AND MON AS THE UPPER TROF LIFTS N."
