AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 321 PM EDT THU JUL 18 2013 .DISCUSSION... THIS AFTERNOON-TONIGHT...RADAR AND SATELLITE IMAGERY SHOW A SPLIT PATTERN ACROSS THE PENINSULA THIS AFTERNOON AS THE LOW LEVEL TROUGH AXIS LIFTS THROUGH THE I-4 CORRIDOR. THE UPPER LEVEL LOW HAS SHIFTED WELL INTO THE CENTRAL GULF OF MEXICO THIS AFTERNOON THOUGH SEVERAL VORTICITY MAXIMA CONTINUE TO ROTATE AROUND ITS EASTERN PERIPHERY ALONG THE EAST GULF AND WEST FLORIDA. THE ONGOING CONVECTION IN THESE AREAS CONTINUES TO OVERSPREAD THE REGION AND HAS KEPT DAYTIME HIGHS IN THE MID 80S. DUE TO THE LACK OF SIGNIFICANT HEATING...COVERAGE OF SHOWERS AND STORMS HAS SO FAR REMAINED LOW. LOCAL WRF INDICATES THE BEST RAIN CHANCES COMING LATE THIS EVENING AS THE SOUTHERLY STEERING FLOW INCREASES AND THE ONGOING ACTIVITY OVER SOUTHWEST FLORIDA LIFTS NORTHWARDS. THIS SEEMS LIKE A REASONABLE SCENARIO GIVEN THE CURRENT RADAR PICTURE...WITH THE BEST RAIN COVERAGE EXPECTED ACROSS OKEECHOBEE...OSCEOLA...AND SOUTHERN PORTIONS OF THE ORLANDO METRO THIS EVENING. ACTIVITY MAY LINGER THROUGH MIDNIGHT...WITH MOSTLY CLOUDY SKIES THROUGH THE REMAINDER OF THE NIGHT. OVERNIGHT LOWS IN THE LOW TO MID 70S. FRI-SUN...SUBTROPICAL RIDGE BUILDS BACK INTO CENTRAL FLORIDA ON FRIDAY WITH THE AXIS GRADUALLY SHIFTING SOUTH INTO THE WEEKEND AS A LARGE STORM SYSTEM MOVES ACROSS THE NORTHEAST. NO SIGNIFICANT UPPER LEVEL FEATURES ALOFT...BUT A VERY MOIST AIRMASS WILL REMAIN IN PLACE CONTINUING A WETTER PATTERN OVER EAST CENTRAL FLORIDA WITH ABOVE NORMAL RAIN CHANCES IN THE FORECAST EACH DAY. ENHANCED STORM ACTIVITY WILL OCCUR WITH ANY BOUNDARY INTERACTIONS ALONG THE EAST COAST SEA BREEZE WHICH SHOULD DEVELOP AND STAY NEAR THE COAST EACH AFTERNOON AS STEERING FLOW SHIFTS OUT OF THE SOUTH AND SOUTHWEST. HIGHS WILL REACH UP TO THE UPPER 80S TO LOW 90S AND OVERNIGHT LOWS WILL RANGE FROM THE LOW/MID 70S. FROM PREVIOUS DISCUSSION... MON-WED...DEEPENING U/L TROUGH OVER THE EASTERN U.S. WILL KEEP AXIS OF THE SUBTROPICAL RIDGE NEAR TO JUST SOUTH OF LAKE OKEECHOBEE FROM EARLY TO MID WEEK. MOISTURE REMAINS SUFFICIENT FOR SCATTERED AFTERNOON SHOWERS AND STORMS EACH AFTERNOON WITH ACTIVITY SHIFTING TOWARD THE EAST COAST FROM MID TO LATE AFTERNOON AND INTERACTING WITH A STALLED SEA BREEZE NEAR THE EAST COAST. TEMPERATURES REMAIN NEAR TO SLIGHTLY ABOVE NORMAL. && .AVIATION... SCT SHRA/ISOLD TSRA THROUGH 19/03Z...WITH THE BEST COVERAGE ACROSS TREASURE COAST...OKEECHOBEE INTO THE ORLANDO METRO. ISOLD TSRA OVER ATLC WATERS THROUGH OVERNIGHT HOURS. BETTER COVERAGE EXPECTED ON FRIDAY AS STEERING FLOW SHIFTS OUT OF THE SOUTH-SOUTHWEST AND MORE ACTIVITY CONCENTRATES ON THE EASTERN SIDE OF THE PENINSULA. && .MARINE... TONIGHT-FRIDAY...PREVAILING SOUTHERLY FLOW THROUGH PERIOD AS WEAK LOWER LEVEL TROUGH SHIFTS OUT OF THE AREA AND RIDGE AXIS BUILDS IN ACROSS THE CENTRAL PENINSULA. SPEEDS 10KTS OR LESS OVERNIGHT...BECOMING 10-15KTS BY THE AFTERNOON AS THE GRADIENT TIGHTENS SLIGHTLY. WINDS WILL BACK MORE SOUTHEAST ALONG THE IMMEDIATE COAST IN THE AFTERNOON WITH THE DEVELOPMENT OF THE EAST COAST SEA BREEZE. SEAS 2-3FT WITH DOMINANT PERIODS 7 TO 8 SEC. SOME REDEVELOPMENT OF CONVECTION EXPECTED OVER THE WATERS TONIGHT IN MOIST SOUTHERLY FLOW. SAT-MON...SUBTROPICAL RIDGE SHIFTS IN SOUTH FLORIDA THROUGH THE WEEKEND INTO EARLY NEXT WEEK. SOUTH-SOUTHWEST FLOW PREVAILS SAT AND THEN VEERS TO THE S/SW SUN/MON. WIND SPEEDS REMAIN AROUND 10-15 KNOTS WITH SEAS INCREASING UP TO 4 FEET OFFSHORE INTO THE WEEKEND. GREATER MOISTURE OVER THE AREA WILL LEAD TO HIGHER COVERAGE OF SHOWERS AND STORMS WITH A CHANCE FOR OFFSHORE MOVING STORMS EACH AFTERNOON. && .PRELIMINARY POINT TEMPS/POPS...
