CONVECTION CONTINUES TO DROP SOUTH ALONG THE FLORIDA PENINSULA ALONG
WITH THE PRE-FRONTAL TROUGH. LOOKS AS IF ENOUGH MID LEVEL DRY AIR IS

IN SPITE OF THE HEATING AND WEST COAST SEA BREEZE. A FEW SHOWERS HAVE
DEVELOPED IN THE SOUTH BREVARD COUNTY COASTAL WATERS.

TREND SHOULD CONTINUE TONIGHT WITH CLEARING SKIES TO THE NORTH. WINDS
WILL GO TO THE NORTHEAST BY SUNRISE IN MOST AREAS AS THE UPPER TROUGH
KICKS TO THE EAST. MODELS KEEP SOME LOW LEVEL MOISTURE ACROSS CENTRAL
AND SOUTH FLORIDA TONIGHT AND INTO FRIDAY...JUST ENOUGH TO KEEP SOMxE
CU IN THE TERMINAL FORECASTS AND POSSIBLY SOME POPS MELBOURNE SOUTH.
