EAST CENTRAL FLORIDA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 245 PM EDT SAT AUG 18 2001 CURRENTLY...BOTH ATLANTIC AND GULF BREEZES HAVE DEVELOPED AND ARE MOVING INLAND...QUITE UNDISTURBED BY CONVECTION. THIS SHOULD LEAD TO MORE OR LESS A TRUE SEA BREEZE COLLISION OVER THE INTERIOR COUNTIES...NEAR THE ORLANDO METRO AREA OR JUST EAST...LATER THIS AFTN/EVE. SOME OF THE RESULTING STORMS WILL BE STRONG. UNTIL THEN... OTHER STORMS...SOME STRONG...WILL DEVELOP AS THE EAST COAST BREEZE INTERACTS WITH THE LAKE OKEECHOBEE BREEZE (SEEN ON VIS SAT IMAGERY) AND OTHER LAKE BOUNDARIES. UPPER TROUGH DEEPENS OVER EASTERN U.S. AND SFC FRONT DROPS INTO THE DEEP SOUTH DURING THE NEXT 48 HOURS.

BUT MODEL RUN TO RUN CONSISTENCY HAS INCREASED OUR CONFIDENCE THAT HIGHER POPS ARE IN ORDER MON FOR SOUTHERN ZONES (50%)...BUT BAND OF SUBSIDENCE MOVING UP THE PENINSULA SHOULD KEEP POPS LOWER ELSEWHERE. EXTENDED FORECAST IS HIGHLY DEPENDENT ON TRACK AND INTENSITY OF CHANTAL.
