AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 246 PM EDT SAT JUN 20 2015 .DISCUSSION... THRU TONIGHT...SHOWER AND STORM COVERAGE WILL INCREASE AS DAYTIME HEATING AND BOUNDARY COLLISIONS CONTINUE THROUGH THE LATE AFTERNOON. MAXIMUM COVERAGE SHOULD BE BETWEEN 4 AND 7 PM WITH A FEW STRONG STORMS PRODUCING FREQUENT LIGHTNING...HEAVY RAIN...AND GUSTY WINDS. LIGHT STEERING FLOW ALOFT MEANS MUCH OF TODAYS ACTIVITY WILL BE BOUNDARY DRIVEN...AND SIMILAR TO YESTERDAY...WILL WATCH FOR STORM PROPAGATION BACK CLOSER TO THE COAST THIS EVENING. WARM AND HUMID EVENING AGAIN TONIGHT WITH OVERNIGHT TEMPS IN THE LOW TO MID 70S. SUNDAY...SURFACE RIDGE REMAINS ACROSS CENTRAL/SOUTH FLORIDA WITH GENERALLY LIGHT SOUTH AND WEST FLOW CONTINUING. MODELLING INDICATES A SLIGHT DROP OFF IN AVAILABLE MOISTURE AND SUBSEQUENTLY KEEPS POPS A BIT LOWER. STILL EXPECTING ISOLATED/SCATTERED CONVECTION ACROSS THE INTERIOR AS THE WEST AND EAST COAST SEA BREEZES INTERACT LATE IN THE AFTERNOON. PLENTY OF SOLAR INSOLATION MEANS TEMPS WILL ONCE AGAIN WARM UP INTO THE LOW TO MID 90S. FROM PREVIOUS DISCUSSION... MONDAY...THE ATLC RIDGE LOOKS TO STRENGTHEN ON MONDAY AS ALLOW STRONGER LOW LVL SE WINDS ACROSS E CENTRAL FL IN THE AFTERNOON. THIS SHOULD ALLOW THE EAST COAST SEA BREEZE TO PUSH INTO INTERIOR SECTIONS WITH SHOWER/TSTM CHANCES AROUND 20 PCT ACROSS THE CSTL ZONES TO 30 PCT OVER THE INTERIOR...LOWER THAN RECENT DAYS. HIGHS WILL BE IN THE LOWER 90S TREASURE COAST TO MID 90S ACROSS THE INTERIOR. TUE...LOW LVL SE FLOW CONTINUES TUE WITH 594 DM RIDGE AT H5 ELONGATING NORTH OF THE STATE.

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
