AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 213 PM EDT WED AUG 5 2009 .DISCUSSION... NOW-THURSDAY...UPPER LEVEL TROUGH CONTINUES TO LINGER ACROSS THE SOUTHEAST AIDED BY SHORTWAVES MOVING THROUGH THE TENNESSEE AND UPPER OHIO VALLEYS. SIMILAR TO THIS MORNING...AN EARLY AFTERNOON SOUNDING AT KXMR CONTINUES TO INDICATE AN UNSTABLE ATMOSPHERE WITH PWATS CONTINUING TO ABOVE 2 AND TEMPS AT 500 MB AT -8C. OUTFLOW FROM THE EARLIER COMPLEX OF STORMS OVER THE EASTERN GULF AND TAMPA BAY HAS SET OFF A NEW WAVE OF STORMS ADVANCING INTO SOUTHERN LAKE...ORANGE AND OSCEOLA COUNTIES IN ADDITION TO THE DEVELOPMENT ALONG THE EAST COAST SEA BREEZE ALONG THE COAST. STEERING FLOW THIS EVENING WILL CONTINUE TO FAVOR THE CENTRAL TO EAST PENINSULA FOR AFTERNOON/EVE STORMS. OUTFLOW BOUNDARY/SEA BREEZE COLLISIONS WILL CONTINUE THROUGH THE MID EVENING HOURS WITH A SOUTH ZIP DOWN THE EAST COAST POSSIBLE INTO THE EVENING. COLDER TEMPS ALOFT WILL BRING A SLIGHTLY HIGHER THREAT FOR STRONG TO SEVERE STORMS THAN OVER THE PAST FEW DAYS. FREQUENT LIGHTNING...HAIL...POSSIBLE WATERSPOUTS AND FUNNEL CLOUDS...AND STRONG GUSTY WINDS WILL BE THE MAIN CONCERNS. THOUGH STORM MOTION IS A LITTLE FASTER THAN IN PREVIOUS DAYS...SLOW MOVING STORMS WILL STILL BE CAPABLE OF PRODUCING ROUNDS OF TORRENTIAL RAINFALL. HIGHEST COVERAGE OF STORMS WILL ONCE AGAIN BE JUST EAST OF THE ORLANDO METRO AND OVER THE ST JOHNS RIVER. DESPITE MODEL ATTEMPTS TO THE REASSERT THE SUBTROPICAL RIDGE AND SCOOT IT NORTH...IT APPEARS THAT THE PRESENCE OF THE UPPER LEVEL TROUGH WILL KEEP THE RIDGE AXIS OVER THE SOUTHERN PORTION OF THE REGION TOMORROW. LITTLE CHANGE IN THE PATTERN IS EXPECTED FROM TODAY INTO THURSDAY WITH SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS DEVELOPING BY THE LATE AFTERNOON. FRI-SUN...TROUGH THAT WAS ACROSS THE SE ATLC COAST ON THU WILL MOVE OFFSHORE FRIDAY AND THE ATLC AND SE US MID LVL RIDGE WILL STRENGTHEN INTO FRI AFTN. LOW TO MID LYR FLOW WILL TRANSITION TO ONSHORE THIS PERIOD WITH STRONG MID LVL RIDGE ACROSS THE SE STATES AND CAROLINAS. THE RIDGE ALOFT WILL CONTRIBUTE TO DECREASING MOISTURE LEVELS AND RAIN SHOWER/TSTM CHANCES OVER THE WEEKEND MAINLY FAVORING INTERIOR AND FAR SRN SECTIONS EACH AFTERNOON. SHOULD SEE MOSTLY SUNNY SKIES AT THE BEACHES WITH THE EAST COAST SEA BREEZE PUSHING INLAND BY MID AFTERNOON EACH DAY. EXPECT THE RISK FOR RIP CURRENTS TO BE ELEVATED WITH AN EAST SWELL DEVELOPING OVER THE ATLC WATERS. HIGHS WILL REACH IN THE MID 90S OVER THE INTERIOR WITH LESS STORM COVERAGE EXPECTED THIS WEEKEND. MON-WED...MID LVL RIDGE WILL PUSH OFFSHORE THROUGH THE MIDDLE OF NEXT WEEK THOUGH LOW LVL SE FLOW WILL CONTINUE. MOISTURE LEVELS STILL PROGD TO REMAIN BELOW NORMAL WITH THE WANING INFLUENCE OF THE RIDGE NORTH OF THE AREA. THIS SHOULD SUPPORT POPS IN THE 30-40 PCT RANGE...MAINLY OVER INTERIOR SECTIONS EACH AFTERNOON...AND LOWER POPS ALONG THE IMMEDIATE COAST AND BEACHES. HIGHS NEAR 90 COAST AND LWR 90S FOR THE INTERIOR. && .AVIATION...SCT-NMRS SHRA/TSRA AREA-WIDE WILL PRODUCE TEMPO MVFR/IFR CONDITIONS WITH POSSIBLE GUSTY WINDS NEAR 35KTS IN STRONGER STORMS. HIGHEST STORM COVERAGE EXPECTED 21Z-01Z. ACTIVITY WILL RAPIDLY DIMINISH AFTER 02Z WITH LINGERING MID AND HIGH CLOUDS. && .MARINE... TONIGHT-THURS...S/SE FLOW 5-10 KTS WILL PREVAIL TODAY AND TONIGHT. SEAS WILL BE AOB 3 FT. WEAK WESTERLY STEERING FLOW MAY BE ABLE TO PUSH STORMS OFFSHORE MAINLY ALONG THE VOLUSIA/N BREVARD COUNTY COASTS THIS AFTERNOON/EVENING AND AGAIN ON THURSDAY. FRI-MON...E/SE FLOW WILL CONTINUE THROUGH EARLY NEXT WEEK MAINLY AROUND 10 KTS. AN EASTERLY SWELL COMPONENT WILL RAISE SEAS TO 3-4 FT OFFSHORE BUT OVERALL LOOKS LIKE A GOOD BOATING WEEKEND WITH LOWER THAN NORMAL STORM COVERAGE AND EASTERLY WINDS PUSHING STORMS AWAY FROM THE INTRACOASTAL DURING THE AFTERNOONS. && .PRELIMINARY POINT TEMPS/POPS...

A FEW SLOW MOVING STORMS WILL BE ABLE TO PRODUCE LOCALLY HEAVY RAINFALL AMOUNTS UP TO 2 TO 3 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... WESTERLY STEERING FLOW WILL PRODUCE A LOW THREAT FOR OFFSHORE MOVING THUNDERSTORMS...MAINLY ALONG THE VOLUSIA AND BREVARD COUNTY COASTLINE. FREQUENT CLOUD TO WATER LIGHTNING STRIKES AND WIND GUSTS TO AROUND 35 KNOTS WILL BE POSSIBLE WITHIN THE STRONGEST STORMS AS THEY MOVE ALONG EAST TO SOUTHEAST OVER COASTAL AREAS. INLAND LAKES WILL ALSO HAVE A LOW THREAT OF STORMS PRODUCING WIND GUSTS NEAR 35 KNOTS ALONG WITH DEADLY LIGHTNING. ...WATERSPOUT IMPACT... A BRIEF FUNNEL CLOUD OR WATERSPOUT WILL BE POSSIBLE AT THE COAST AND INTRACOASTAL WATERS MAINLY LATE THIS MORNING AND EARLY AFTERNOON DURING THE INITIAL VIGOROUS GROWTH PHASE IN DEVELOPING STORMS. CONDITIONS FOR THIS ARE HISTORICALLY HIGHER OVER THE INTRACOASTAL WATERS AND MERRITT ISLAND AS THE EAST COAST SEA BREEZE BOUNDARY MOVES INLAND OR REMAINS STATIONARY ALONG THE COAST. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY. HIGH PRESSURE RIDGE AXIS WILL REMAIN FIXED ACROSS THE CENTRAL FLORIDA PENINSULA THROUGH FRIDAY THEN MOVE NORTH OF THE AREA DURING THE WEEKEND. SCATTERED STORMS WILL DEVELOP EACH AFTERNOON WITH GREATEST CHANCES OCCURRING WITH ANY SEA BREEZE BOUNDARY INTERACTIONS OVER THE INTERIOR. THE THREAT OF RIP CURRENTS WILL INCREASE THIS WEEKEND INTO EARLY NEXT WEEK. .SPOTTER INFORMATION STATEMENT... SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE IF NEEDED. PENDERGRAST
