NWS Melbourne, FL wrote its last area forecast discussion before the first event at Aug 3, 8:29 AM EST, 4 hours 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 929 AM EDT MON AUG 3 20090 .DISCUSSION... SIMILAR WEATHER PATTERN TO YESTERDAY AS RIDGE AXIS REMAINS ACROSS THE FL PENINSULA. THE REMNANTS OF A FRONTAL BOUNDARY THAT MOVED THROUGH THE MID-ATLANTIC HAS BROUGHT INCREASED MOISTURE AND SHIFTED THE RIDGE AXIS JUST A LITTLE FURTHER SOUTH THAN YESTERDAY. THIS HAS RESULTED IN A LITTLE MORE S-SW FLOW ACROSS THE REGION...WHICH MAY BE ENOUGH TO KEEP THE EAST COAST SEA BREEZE A LITTLE FURTHER EAST IN BREVARD COUNTY THAN YESTERDAY. THE GENERAL FLOW PATTERN REMAINS THOUGH FOR FASTER/FARTHER INLAND MOVEMENT OF THE BOUNDARY SOUTH OF THE CAPE AND SLOWER/LESS INLAND PROGRESSION NORTH. HIGHEST RAIN CHANCES WILL THEN EXIST OVER THE INTERIOR AND NORTHERN COAST (AROUND 40-50%) WHERE OUTFLOW BOUNDARY/SEA BREEZE COLLISIONS WILL OCCUR LATE IN THE DAY THROUGH THE EARLY EVENING HOURS. A FEW STRONG STORMS WILL BE POSSIBLE WITH ANY BOUNDARY INTERACTIONS WITH FREQUENT LIGHTNING...STRONG GUSTY WINDS...AND TORRENTIAL DOWNPOURS BEING THE MAIN THREATS. WILL INCLUDE UPDATES TO THE MORNING ZONES TO INCLUDE THE POSSIBILITY FOR MORNING SHOWERS MOVING ONSHORE THE TREASURE COAST. && .AVIATION...PREVAILING VFR THROUGH 15Z WITH ISOLD SHRA MOVING ONSHORE SOUTH OF KVRB. ISO/SCT SHRA/TSRA DEVELOPING ALONG EAST COAST SEA BREEZE AFTER 15Z WITH TEMPO IFR/MVFR CONDS. HIGHEST STORM COVERAGE EXPECTED OVER THE INTERIOR WITH EAST-WEST COAST SEA BREEZE COLLISION AROUND 22Z-02Z SO HAVE CONTINUED VCTS DURING THIS TIME PERIOD FOR THE INTERIOR TAF SITES. && .MARINE... S/SE FLOW AROUND 10 KTS OR LESS WILL PREVAIL TODAY AND TONIGHT UNDER A PERSISTENT HIGH PRESSURE RIDGE AXIS STRETCHED OVER THE AREA. SEAS WILL CONTINUE TO RUN 2-3 FT. WEAK WESTERLY STEERING FLOW MAY BE ABLE TO PUSH A FEW STORMS OFFSHORE FROM THE CAPE NORTHWARD LATE THIS AFTERNOON. SEAS REMAIN IN THE 1-3 FT RANGE FROM TUE THROUGH MIDWEEK. SOMEWHAT HIGHER SEAS ARE INDICATED SHOWN OFFSHORE DUE TO DEVELOPMENT OF EASTERLY FETCH UNDERNEATH LIFTING RIDGE AXIS. && .MLB WATCHES/WARNINGS/ADVISORIES... FL...NONE. AM...NONE. && MOSES/VOLKMER

STORM COVERAGE WILL BE A LITTLE GREATER TODAY DUE TO INCREASING MOISTURE OVER THE AREA FROM THE GULF OF MEXICO. ISOLATED TO SCATTERED STORMS WILL INITIALLY DEVELOP ALONG THE EAST COAST SEA BREEZE THIS AFTERNOON. HIGHEST STORM COVERAGE WILL THEN OCCUR LATE IN THE DAY OVER THE INTERIOR AND NORTHERN COAST WHERE COLLISIONS OF SEA BREEZE AND OUTFLOW BOUNDARIES ARE MOST LIKELY. A FEW STRONG STORMS WILL BE POSSIBLE WITH THESE BOUNDARY INTERACTIONS WITH THE MAIN THREATS BEING FREQUENT CLOUD TO GROUND LIGHTNING...STRONG WIND GUSTS...AND TORRENTIAL DOWNPOURS. ...FLOOD IMPACT... WEAK STEERING FLOW WILL LEAD TO SLOW TO STATIONARY STORM MOTION THIS AFTERNOON. ANY STRONGER STORMS WILL BE ABLE TO PRODUCE LOCALLY HEAVY RAINFALL UP TO 2 TO 4 INCHES...ESPECIALLY THOSE STORMS THAT FORM DUE TO BOUNDARY COLLISIONS OVER THE INTERIOR LATE TODAY. THIS AMOUNT OF RAINFALL CAN PRODUCE MINOR FLOODING OF URBAN...LOW LYING...AND POOR DRAINAGE AREAS. ...MARINE THUNDERSTORM GUST IMPACT... SCATTERED STORMS WILL DEVELOP ACROSS LAND AREAS THIS AFTERNOON. A WEAK WESTERLY STEERING FLOW NORTH OF THE CAPE WILL KEEP A LOW THREAT FOR OFFSHORE MOVING THUNDERSTORMS...MAINLY ALONG THE VOLUSIA COUNTY COASTLINE. FREQUENT CLOUD TO WATER LIGHTNING STRIKES AND WIND GUSTS TO AROUND 35 KNOTS WILL BE POSSIBLE WITH ANY STRONGER STORMS. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
