Satellite imagery over Florida shows an upper level low pressure trough extending southward over the eastern Gulf of Mexico.  At the surface, high pressure ridge axis is currently aligned east to west across extreme south Florida and the Florida Straits.  This synoptic setup once again places the peninsula within a deep layered, moist, southerly wind flow.  In such a regime all that is generally needed to generate widespread showers and thunderstorms is strong diurnal heating, instability creation, and local boundaries, i.e. sea breezes.  Today will be no different.  All activity will generally travel south to north and intensify along boundary collisions.
