The frontal boundary across North Florida could make it toward Dead Central around midnight, and slight low level convergence along that boundary could shift increasing rain chances toward the SE from NW Florida later today, but timing is a tricky factor considering the ongoing scenario currently in place.
There was some large rainfall totals over 4" yesterday in Okeechobee County, so localized flash 'flooding' is possible there, although the main core of rain is not 'expected' to reach that zone. Guidance 'seems' to be a somewhat of agreement that it will be the north 1/2 of the state that will receive the main flux of rainfall, but no area can be counted out once localized boundaries come into play and considering it is already raining over portions of South Florida early on today.
BEYOND TODAY: Shower chances early on along the east coast of Central tomorrow morning but this activity will press off toward SW Florida during the day. After that time, Wednesday through Friday look mostly dry, although another boundary will skirt by off shore with little to no impact Morning lows along the coast in the mid-upper 70Fs south of the Cape and afternoon highs in the 80Fs and lows 90Fs along the SW side of the state.
