AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 955 AM EDT THU MAY 5 2005 ...ANOTHER WET/STORMY DAY...THEN IMPROVING WX FRI ONWARD... .DISCUSSION... OLD FRONTAL BOUNDARY LYING ACROSS NORTHERN FRINGES OF EC FL AT PRESENT WITH SHOWERS/STORMS CONFINED NEAR/NORTH OF THE BOUNDARY. THIS PLACES ALL OF EAST CENTRAL FLORIDA IN THE WARM SECTOR TODAY. SURFACE WAVE DEVELOPING ALONG THE BOUNDARY IN THE EASTERN GULF WILL TRAVERSE THE PENINSULA THEN DEEPEN AND LIFT NE OVER THE ATLANTIC TONIGHT AND FRI. WATER VAPOR PIX AND RUC80 SHOW MID/UPPER TROUGH DIGGING ACROSS NE GULF/PANHANDLE REGION WITH GOOD UPPER LEVEL DIVERGENCE EXTENDING ACROSS THE PENINSULA. DEBRIS CLOUDINESS MOVING ACROSS NORTHERN/CENTRAL SECTIONS FROM GULF MCS MAY ACT TO DELAY START OF CONVECTION A LITTLE...BUT ALREADY SIGNS OF THINNING/BREAKS ON EARLY VIS SAT IMAGES...SO SHOULD BE ABLE TO BREAK OUT SOME PARTIAL SUNSHINE WHICH WILL HELP HEATING/DESTAB. MORNING CAPE SOUNDING HAS A LITTLE DRYING IN THE H95-H8 LAYER BUT MESONAM INDICATES MOISTENING WILL OCCUR IN THIS LAYER BY MIDDAY. C FL MORN SOUNDINGS STILL RELATIVELY COOL ALOFT WHICH WILL ENHANCE INSTABILITY AND HAIL POTENTIAL. COVERAGE OF SHOWERS AND STORMS SHOULD BECOME WIDESPREAD THIS AFTERNOON AND POPS ALREADY QUITE HIGH IN ZONES/GRIDS SO WILL NOT MAKE CHANGES HERE. WILL UPDATE HWO/GHWO TO REFINE THREATS BASED ON 12Z MESO MODELS/MORNING SOUNDINGS. IN ADDITION TO HAIL AND STRONG WIND THREATS...WILL NEED TO BE MINDFUL OF BRIEF TORNADO/SPOUT FORMATION AS STORMS APPROACH THE COAST AND ENCOUNTER BETTER LOW LEVEL SHEAR. SOUTHERN SECTIONS MORE LIKELY TO HAVE A SEA BREEZE FORM BUT WILL ALSO NEED TO MONITOR THE NORTH SINCE THE FRONTAL BOUNDARY IS IN CLOSE PROXIMITY OF VOLUSIA COUNTY. ANOTHER HAZARD WILL BE URBAN/STREET FLOODING WITH STORMS...ESP IN AREAS THAT HAVE RECEIVED RECENT HEAVY RAINS. && .MARINE...MAIN CONCERN FOR BOATERS TODAY WILL BE STRONG OFFSHORE MOVING THUNDERSTORMS WITH POTENTIAL TO PRODUCE STRONG WIND GUSTS AND A FEW WATERSPOUTS.
