AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 930 AM EDT MON AUG 5 2013 .DISCUSSION... CURRENT-THIS AFTERNOON...RUC ANALYSIS PLACES UPPER RIDGE FROM TEXAS TO CUBA AND THE PERSISTENT WEAK TROUGHING ACROSS NORTH FLORIDA AND SOUTHERN GEORGIA AND ALABAMA AND HIGH PRESSURE STRETCHING ACROSS THE FLORIDA STRAITS TO THE TEXAS OLD MEXICO BORDER AREA (MOUTH OF THE RIO GRANDE). THE VERTICAL WIND PROFILERS AT KENNEDY SPACE CENTER WERE SHOWING A VEERING OF THE WIND FROM THE SURFACE TO AROUND 4000 FEET AND WESTERLY ABOVE 4000 FEET. THE LOW LEVEL VEERING IS A GOOD SIGNAL THAT THE TROUGHING IS FINALLY STARTING TO LIFT NORTH AND TO BE REPLACED OVERNIGHT BY THE HIGH PRESSURE MOVING NORTHWARD FROM THE FLORIDA STRAITS AND HIGH PRESSURE BUILDING OVER THE SOUTHEAST AND LOWER MISSISSIPPI RIVER VALLEY. THE CURRENT FORECAST FOR THIS AFTERNOON IS INDICATING AN EARLIER START TO THE EAST COAST SEA BREEZE BUT THAT IT WILL STILL NOT MAKE IT VERY FAR INLAND LOOKS GOOD. MORNING UPDATE MOST LIKELY WILL BE WIND GRID CHANGES. PREVIOUS ZONES DISCUSSION TODAY-TONIGHT...UPPER LEVEL WIND PATTERN ACROSS THE PENINSULA STILL BEING DRIVEN BY THE EAST SIDE OF A LARGE RIDGE SPRAWLING ACROSS TEXAS INTO THE GULF OF MEXICO AND THE WESTERN PERIPHERY OF THE EAST COAST/WESTERN ATLANTIC TROUGH. A WEAK FRONT WILL SAG INTO THE NORTHERN PENINSULA TODAY WITH LOW LEVEL WEST-NORTHWEST FLOW AND PRE-FRONTAL MOISTURE INCREASING OVER EAST CENTRAL FLORIDA FROM NORTH TO SOUTH. WITH THE FRONTAL BOUNDARY ACROSS THE REGION AND HIGHER MOISTURE COVERAGE OF SCATTERED SHOWERS AND STORMS WILL BE A LITTLE BETTER TODAY THAT YESTERDAY. WINDS WILL BECOME NORTH-NORTHEAST BEHIND THE BOUNDARY ACROSS VOLUSIA AND NORTHERN LAKE COUNTY BY THE EARLY AFTERNOON...WITH MODELS SHOWING THIS WIND SHIFT LEADING TO A QUICK INLAND PUSH OF THE EAST COAST SEA BREEZE UNCHARACTERISTICALLY NORTH OF THE CAPE FIRST.

SIMILAR TO YESTERDAY...THERE ARE ALREADY A FEW SHOWERS DEVELOPING ALONG THE WEST COAST OF FLORIDA. A FEW OF THESE COULD BRUSH LAKE COUNTY THROUGH SUNRISE...ALONG WITH ADDITIONAL DEVELOPMENT ACROSS THE FAR NORTHERN SECTIONS OF LAKE AND VOLUSIA AND THE BOUNDARY STARTS TO SAG INTO THE AREA.

SHOWERS AND STORMS ENDING A FEW HOURS AFTER SUNSET...WITH PARTLY CLOUDY SKIES THROUGH THE OVERNIGHT HOURS. HIGHS IN THE LOW 90S FOR THE INTERIOR AND AROUND 90 ALONG THE COAST. TUESDAY...LOW LVL ONSHORE FLOW WILL DEVELOP BEHIND A DISSOLVING FRONTAL BOUNDARY AS HIGH PRESSURE NOSES DOWN THE MID ATLC. NORTHERLY FLOW ALOFT WILL BECOME NE WITH ADEQUATE MOISTURE FOR DEVELOPMENT OF SCATTERED DIURNAL SHOWERS AND THUNDERSTORMS THAT WILL BE MORE CONCENTRATED ACROSS INTERIOR SECTIONS AS THE EAST COAST SEA BREEZE PUSHES INLAND IN THE MID TO LATE AFTERNOON. POPS WILL RANG FROM 30 PCT ALONG THE COAST TO 50 PCT ACROSS LAKE COUNTY AND THE KISSIMMEE RIVER BASIN. HIGHS WILL BE NEAR 90 ALONG THE COAST AND THE LOWER 90S ACROSS THE INTERIOR. WEDNESDAY...AN UPPER TUTT LOW WILL BE MOVING WESTWARD THROUGH THE BAHAMAS BY WED AFTERNOON INTO WED NIGHT WITH DRY AIR ALOFT NW OF THE UPPER LOW. AT THE SFC...GFS/NAM INDICATE ONSHORE FLOW WITH DECREASED MOISTURE LEVELS. WILL LEAN TOWARD THE FAIRLY LOW GFS/NAM POPS WITH CSTL SECTIONS IN THE SLIGHT CHANCE RANGE TO 30 PCT CHANCE OVER THE INTERIOR. HIGHS NEAR 90 COAST TO THE LOWER 90S INTERIOR. THURSDAY...THE UPPER LOW WILL PASS WELL SOUTH OF THE STATE ACROSS THE N CUBAN COAST WITH RELATIVELY DRY AIRMASS CONTINUING. LOW LVL FLOW WILL BE SE BUT MOISTURE LEVELS SHOULD REMAIN BELOW NORMAL WITH POPS IN THE 20-30 PCT RANGE. HIGHS UPR 80S COAST TO AROUND 93 INTERIOR. FRI-MON...THE UPPER LOW WILL PULL INTO THE SE GULF ON FRIDAY WITH CONTINUED SE LOW LVL FLOW. SHOULD SEE SLIGHTLY HIGHER POPS ACROSS SRN SECTIONS AS SOME SLIGHTLY DEEPER MOISTURE WORKS IN ACROSS THE AREA. A STRONG MID LVL RIDGE WITH 594-595 DM HEIGHTS WILL MOVE FROM OFF THE EAST COAST SAT TO N FL SUNDAY. THE ATLC RIDGE NORTH OF THE AREA ON SATURDAY WILL GRADUALLY MOVE SOUTH OVER CENTRAL FL BY LATE SUNDAY INTO MONDAY. OVERALL...MOISTURE LEVELS WILL REMAIN LOW AND CONVECTION SHOULD BE SUPPRESSED OVER THE WEEKEND. EXPECT SOME SHOWER/TSTM DEVELOPMENT OVER THE INTERIOR WITH SLGT CHANCES CLOSER TO THE COAST AS THE EAST COAST SEA BREEZE MOVES INLAND EACH AFTERNOON. IT WILL BE A HOT WEEKEND WITH HIGHS AROUND 90/LWR 90S FOR THE COASTAL COUNTIES AND MID 90S OVER THE INTERIOR. MONDAY...THE MID LVL RIDGE WILL MOVE TWD THE WRN GULF COAST.
