Not a lick of rain on the east coast...... Miami NWS does not hold much chance for rain:
".DISCUSSION...SURFACE RIDGING OVER CWA HAS WEAKENED AND THE EAST
COAST SEABREEZE HAS NOT ALLOWED ANY PRECIP OVER THE EAST. THIS
MORNINGS RAOB SHOWED A PWAT OF 1.97" BUT THE LATEST PWAT FROM GOES
IMAGERY SHOWS IT HAS DECREASED TO 1.75". THERE MUST BE SOME DRYING
IN THE MID LEVELS WITH H5 SUBSIDENCE OVERHEAD. HOWEVER...DO EXPECT
SCT POPS UNTIL EARLY EVENING INLAND AND WEST. THIS SCENARIO WILL BE
THE CASE THROUGH THE WEEK AS SURFACE HIGH PRESSURE COMING OFF THE
SOUTHEAST U.S. TAKES OVER AND TURNS THE LOWER LEVEL WINDS MORE EAST
BY TUES. THE MID LEVEL RIDGING MOVES NORTH BY TUES ALLOWING THE MEAN
FLOW TO TO BECOME MORE EASTERLY WITH TIME THIS WEEK.
THE EAST COAST SEA BREEZE CONVERGENCE AREA WILL CONTINUE TO SET UP
WEST OF THE METRO AREAS THIS WEEK...WITH THE STORMS DRIFTING
WESTWARD. THIS THINKING IS IN LINE WITH THE LATEST GFS MOS POP
NUMBERS...WHICH ARE WELL BELOW CLIMO...ALL WEEK LONG. POPS WILL BE
LOW FOR THE EAST THIS ENTIRE WEEK. KEPT HIGH END CHANCE POPS FOR
INTERIOR AND WEST PORTIONS OF THE CWA...AS THE EAST AND WEST COAST
SEA BREEZES WILL INTERACT EACH AFTERNOON TO ALLOW FOR THUNDERSTORM
DEVELOPMENT ACROSS THESE AREAS."

High pressure was responsible for keeping convection pretty much inhibited this afternoon over the east coast of Florida. So even though instability was good (thanks to the combined effects of dewpoints this afternoon in the upper 70s and lower 90s temps at Jacksonville) thunderstorms didn't form over the eastern part of the state.
There is lots of convection over the central part of the state from Lake City southward through Ocala, but isn't moving much because of the weak flow aloft.

Temperatures have come down considerably, although low level moisture is still very plentiful with 70+ dewpoints widespread.

Heavy rainfall is definitely a big concern tonight over the central part of the state.

I suspect this is because of convective interactions, aided by areas of enhanced 0-3 KM CAPE, 1 KM VGP, and maybe to a degree low LCL (Lifted Condensation Level) heights (which are primarily at or below 1000 meters) and abundant boundary layer moisture over much of the state.
Environmental Wind/shear parameters are pretty weak (see sounding in my last post) and would not support (synoptically speaking) much of a tornado threat.
VGP (Vorticity Generation Parameter) measures the rate of vertical tilting and stretching of horizontal vorticity in a thunderstorm's convective updraft, the higher the observed value, the better the potential for tornadoes becomes. High 3 KM CAPE values combined with enhanced surface vorticity also suggests tornadoes via low level stretching.
