NWS Melbourne, FL wrote its last area forecast discussion before the first event at Aug 18, 1:13 PM EST, 5 hours 47 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 213 PM EDT WED AUG 18 2004 .DISCUSSION... TONIGHT...MORE ACTIVE EAST COAST SEA BREEZE THAN YESTERDAY AND SLOWER TO MOVE INLAND AS A RESULT OF SOME LIGHT LOW LEVEL WESTERLY FLOW. WEST COAST SEA BREEZE NOT SHOWING ANY SIGNIFICANT ECHOES YET BUT EVENTUALLY EXPECT IT TO MEET UP WITH THE EAST COAST BOUNDARY OVER THE SPINE OF THE PENINSULA. DIFFICULT TO PICK EXACTLY WHERE THIS WILL OCCUR BUT EARLIER THINKING WAS THAT IT WOULD BE IN THE VICINITY OF I-4. WILL CARRY AN ISOLATED EARLY EVENING POP FOR THE COASTAL COUNTIES AND A LOW SCATTERED NUMBER FOR THE INTERIOR AND NORTH COAST. THURSDAY AND FRIDAY...500MB SHORT WAVE MOVING ACROSS THE NATIONS MIDSECTION PUSHES THE UPPER LEVEL RIDGE SOUTH. CORRESPONDINGLY...THE MAIN PORTION OF SURFACE RIDGE/HIGH IN THE SOUTHWEST ATLANTIC SHIFTS TO NEAR THE NORTHERN BAHAMAS WHILE THE WESTERN MOST SEGMENT OF THE RIDGE ONLY SLIPS TO OUR SOUTHERN CWA RESULTING IN WIND FLOW STAYING OUT OF THE SOUTH AND SOUTHEAST. MAJOR DIFFERENCES BETWEEN THE 12Z ETA AND GFS ARE THEIR POPS... ESPECIALLY FOR TOMORROW/THURSDAY. GIVEN CURRENT SYNOPTIC SITUATION AND FORECAST...590DM HIGH OVERHEAD AND SEAS BREEZES PUSHING PRECIP INLAND...GFS APPEARS WAY OVERDONE WITH 80 POP ALONG THE COAST/60S INLAND. THE ETA LOOKS MORE REALISTIC FOR THIS TIME OF THE SUMMER WITH ITS 30S/40S EVERYWHERE. NO WIN SITUATION WITH THE GFS POPS... UNDERCUT THEM AND GET A FEW HUNDREDTHS AT THE AIRPORTS...YOU BUST... OR STAY WITH THEM AND BUST ON THE COVERAGE. WILL GO CLOSER TO THE ETA POPS AND ONLY BUMP THE NORTHERN COASTAL COUNTIES TO 30/SCATTERED POP WHICH IS CLOSER TO CLIMO. GIVEN THE BIG DIFFERENCES IN MODEL POPS WILL GO WITH CLIMO POP VALUES FOR FRIDAY. SATURDAY THROUGH MONDAY...MINOR SHORT WAVES MOVING THROUGH THE 500MB FLOW OVER THE SOUTHEAST CAUSE THE SURFACE RIDGE AXIS CURRENTLY IN PLACE OVER CENTRAL FLORIDA TO MEANDER UP/DOWN THE CENTER AND NORTHERN PORTIONS OF THE PENINSULA. SURFACE FLOW IS GENERALLY LIGHT TO MODERATE FROM THE SOUTH AND SOUTHEAST DURING THIS PERIOD. FORECAST TIME HEIGHT PROFILES INDICATE THAT WIND SPEEDS THROUGH THE LOWER LAYERS MAY BE A LIMITING FACTOR FOR OVERNIGHT COASTAL SHOWERS DESPITE THE DEPTH OF MOISTURE. TUESDAY AND WEDNESDAY...SURFACE RIDGE POSITIONED OVER NORTH FLORIDA AND SOUTHERN GEORGIA KEEPS WINDS OUT OF THE SOUTHEAST. MOISTURE LEVELS REMAIN HIGH ENOUGH FOR SCATTERED AFTERNOON SHOWERS AND STORMS EACH DAY. && .MARINE...POSITION OF SURFACE RIDGE OVER CENTRAL AND NORTHERN FLORIDA KEEPS WINDS OUT OF THE SOUTHEAST AND SOUTH EXCEPT FOR AFTERNOON SEA BREEZES CONTRIBUTING MORE OF AN EASTERLY COMPONENT ALONG THE COAST AND NEAR SHORE WATERS.
