DISCUSSION
SHOWERS NEAR THE MIAMI COASTLINE WILL GRADUALLY TRACK ACROSS THE
NEARSHORE WATERS TODAY, OCCASIONALLY CROSSING THE ISLAND CHAIN.
SOAKING SHOWERS AREN'T EXPECTED AS THE MOISTURE IS CONCENTRATED TO
THE LOWEST LEVELS OF THE ATMOSPHERE, BUT POCKETS OF MODERATE
RAINFALL ARE POSSIBLE VIRTUALLY ANYWHERE IN THIS ENVIRONMENT.
ELEVATED WINDS IN THE MORNING WILL TAPER OFF THROUGHOUT THE DAY AS
A WEAK BOUNDARY BECOMES STATIONARY SOMEWHERE OVER THE FLORIDA
STRAITS. THIS WILL PROMOTE POOR TO FAIR DISPERSION INDICES AFTER
TODAY. AMPLE LOW LEVEL MOISTURE WILL ENCOURAGE MINIMUM RH VALUES
TO PLATEAU AROUND 70%, AND RECOVER TO NEAR SATURATION OVERNIGHT.
