AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 223 PM EDT SUN SEP 5 2010 .DISCUSSION... CURRENT/TONIGHT...SCT SHOWERS/STORMS WILL FILL IN FROM THE WEST THE REST OF THE AFTERNOON AND LINGER PAST DARK WITH STEADY DISSIPATION FOR ALL BUT THE MARINE AREA BY THE EARLY MORNING HOURS ON MONDAY. BOUNDARY INTERACTIONS OVER THE INTERIOR ESPECIALLY ALONG/NORTH OF THE INTERSTATE FOUR CORRIDOR SHOULD PRODUCE SOME RAIN TOTALS NEAR AN INCH IN HEAVIER SHOWERS. AREA PUSHING INTO CENTRAL FL RELATED TO THE WEST COAST BREEZE BOUNDARY AND APPEARS INDEPENDENT OF THE DEEP CONVECTION OVER THE SHELF WATERS OF THE GULF COAST. LABOR DAY... PRESENCE OF HIGH MOISTURE AND COOLER THERMODYNAMIC PROFILE WILL LEAD TO HIGH RANGE SCT PRECIP DURING THE COURSE OF THE DAY. FRONTAL TROUGH OVER N CENTRAL FL WILL WASH OUT AND WEAK EASTERLY FLOW WILL BECOME PREVALENT BY MID AFTERNOON. DIURNAL HEATING WITH WEAK STEERING MAY PRODUCE SOME HIGHER RAIN TOTALS...ESP OVER THE INTERIOR AREAS WHERE SLOW MOVING STORMS PERSIST ALONG BOUNDARY MERGERS. MON NIGHT-TUE NIGHT...DEEP LAYER HIGH PRESSURE WILL STATION ITSELF OVER THE SOUTHEAST U.S. AND GULF COAST STATES DURING THIS TIME. WE WILL MAINTAIN A WEAK ONSHORE FLOW (EAST/EAST-NORTHEAST) IN THE LOW-LEVELS. PRECIPITABLE WATER VALUES WILL DIMINISH SOME BUT STILL REMAIN NEAR SEASONAL NUMBERS. WILL MAINTAIN INHERITED NUMBERS FOR POPS (20%) BOTH MON-TUE NIGHTS (AFTER 00Z). WILL CONTINUE TO KEEP LOW END CHANCE POPS (30%) DURING THE DAY ON TUE...BUT WITH THE DEEPER ONSHORE FLOW WILL LIKELY SEE HIGHER POPS TOWARDS THE INTERIOR AND OVER WEST-CENTRAL FLORIDA. LOWS MAINLY IN THE LOWER/MIDDLE 70S WITH HIGHS ON TUE NEAR 90 DEGREES ALONG THE COAST AND LOWER 90S ACROSS THE INTERIOR. WED-SUN...(PREVIOUS DISCUSSION)...RIDGE ALOFT WILL COVER THE AREA. AT THE SURFACE...HIGH PRESSURE RIDGE TO THE NORTH WILL WEAKEN MID WEEK AS FRONTAL BOUNDARY PUSHES ACROSS THE COAST TO OUR NORTH...THEN REBUILD LATE IN THE WEEK. THE NET RESULT WILL BE A MOSTLY LIGHT ONSHORE FLOW PATTERN. MOISTURE BAND LEFT OVER FROM OLD FRONTAL BOUNDARY SHOULD GRADUALLY BECOME DIFFUSE THROUGH THE PERIOD. WILL NOT MAKE ANY CHANGES TO THE CURRENT FORECAST WHICH HAS NO GREATER THAN 30 PERCENT RAIN CHANCES. GENERALLY EXPECT COASTAL SECTIONS TO HAVE CHANCES DURING THE NIGHT/MORNING. THE GREATEST CHANCE FOR STORMS WILL BE ACROSS THE INTERIOR IN THE AFTERNOON. && .AVIATION... SCT TSRA WITH MVFR AND ISOLD IFR THROUGH 01Z.
