AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 1035 AM EDT TUE AUG 28 2012 .DISCUSSION... ...AFTERNOON SHOWERS AND STORMS WITH LOCALLY HEAVY RAINFALL... MORNING CAPE SOUNDING SHOWS HIGH MOISTURE WITH PWATS 2.2 INCHES AND DEEP SOUTHERLY FLOW ON THE BACKSIDE OF TC ISAAC APPROACHING THE LA COAST. THERE WILL BE CONSIDERABLE CLOUDINESS BUT WILL SEE BETTER SFC HEATING THAN PREVIOUS DAYS SO WILL MAINTAIN LIKELY (60-70 PERCENT) POPS FOR ABOVE NORMAL COVERAGE OF SHOWERS AND STORMS LIFTING SOUTH TO NORTH. ALTHOUGH THE RAINS TODAY WILL NOT BE DIRECTLY ASSOCIATED WITH TC ISAAC...THERE SHOULD BE NARROW NORTH-SOUTH BANDS OF HEAVY RAIN THAT DEVELOP THIS AFTN PRODUCING UP TO 2 INCHES IN SOME AREAS. THE FOCUS LOOKS TO BE ACROSS NORTH AND INTERIOR SECTIONS FROM VOLUSIA AND LAKE COUNTIES SOUTHWARD ACROSS METRO ORLANDO AND OSCEOLA. OF COURSE... ADDITIONAL RAINFALL ACROSS OKEECHOBEE AND THE TREASURE COAST WILL QUICKLY BECOME RUNOFF AS THE GROUND IS SATURATED THERE. BECAUSE OF THIS HAVE RAISED THE THREAT FOR FLOODING TO MODERATE ACROSS OUR SOUTHERN FA. LOW LEVEL WIND FIELDS WILL DECREASE THROUGH THE DAY BUT WITH SOME SFC HEATING THINK WE SHOULD SEE SOME GUSTS...UP TO 30 MPH POSSIBLE.
