AN APPROACHING SHORTWAVE TROUGH AND SURFACE BOUNDARY TO THE NORTH WILL HELP POOL DEEPER MOISTURE VALUES ACROSS EAST CENTRAL FLORIDA. THE SOUTHWEST WINDFLOW AHEAD OF THE SURFACE BOUNDARY WILL INHIBIT OR PIN THE EAST COAST SEA BREEZE IN VOLUSIA COUNTY BUT IT IS FORECAST TO FORM TO THE SOUTH. THIS BOUNDARY WILL PUSH FARTHEST INLAND FROM THE TREASURE COAST...AND REMAIN CLOSER TO THE COAST HEADING NORTH INTO BREVARD COUNTY. A FEW STORMS MAY MOVE IN FROM WEST CENTRAL FLORIDA DURING THE AFTERNOON IMPACTING AREAS NORTH OF INTERSTATE 4 EARLY AFTERNOON. STORM COVERAGE WILL INCREASE INTO THE LATE AFTERNOON AND EARLY EVENING AS STORMS AND OUTFLOWS FROM THE WEST COAST BOUNDARY COLLIDE WITH THE EAST COAST SEA BREEZE. A FEW OF THE STORMS WILL LINGER INTO THE LATE EVENING BEFORE DISSIPATING. STORMS WILL MOVE TOWARD THE EAST OR SOUTHEAST AROUND 10 MPH. IN ADDITION TO HEAVY DOWNPOURS AND CLOUD TO GROUND LIGHTNING...A FEW STRONGER STORMS MAY PRODUCE FREQUENT CLOUD TO GROUND LIGHTNING STRIKES... SMALL HAIL AND STRONG WIND GUSTS TO AROUND 50 MPH. .RIP CURRENT IMPACT... ELEVATED RIP CURRENT RISK DUE TO WEATHER AND OCEAN CONDITIONS. RIP CURRENTS SHOULD BE AT THEIR STRONGEST FROM MID AFTERNOON INTO THE EARLY EVENING DUE TO TIDAL EFFECTS. CHECK LOCAL CONDITIONS WITH BEACH PATROLS WHEN ARRIVING AT THE BEACH. ALWAYS SWIM WITHIN SIGHT OF A LIFEGUARD AND NEVER SWIM ALONE. .MARINE THUNDERSTORM GUST IMPACT... STORMS WILL BE POSSIBLE OVER INLAND WATERWAYS THIS AFTERNOON AND MOVE ACROSS THE INTRACOASTAL AND NEAR SHORE WATERS LATE AFTERNOON INTO THIS EVENING. THE HIGHEST COVERAGE OF OFFSHORE MOVING STORMS IS EXPECTED NORTH OF PORT CANAVERAL...BUT A FEW STORMS MAY REACH SOUTH TO AROUND JUPITER INLET. STRONGER STORMS MAY PRODUCE GUSTY WINDS OF 35 KNOTS AND FREQUENT CLOUD TO WATER LIGHTNING. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY. SCATTERED LATE DAY LIGHTNING STORM CHANCES WILL CONTINUE THROUGH FRIDAY AS A LOW PRESSURE TROUGH AND DEEPER MOISTURE SAG INTO THE AREA. THE INFLUENCE OF THE TROUGH DECREASES LATE WEEK...AND EXPECTED DEVELOPMENT OF ONSHORE FLOW WILL TEND TO MOVE ISOLATED LATE DAY STORMS TOWARD THE WEST OR SOUTHWEST THIS WEEKEND THROUGH EARLY NEXT WEEK. LOW PRESSURE DEVELOPING TO THE EAST AND HIGH PRESSURE BUILDING DOWN THE EASTERN SEABOARD WILL PRODUCE INCREASING NORTHEAST WINDS AND BUILDING SEAS FRIDAY THROUGH AT LEAST SUNDAY RESULTING IN DETERIORATING BOATING CONDITIONS. .SPOTTER INFORMATION STATEMENT... SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE IF NEEDED. SEDLOCK/WIMMER
