DISCUSSION...THE GFS HAS NOW CONVERTED TO THE WET SIDE WITH AN INCREASE IN POPS THROUGH MUCH OF THE WEEK... AT LEAST COMPARED TO YESTERDAYS RUNS. THIS MORE MOIST TURN OF EVENTS SEEMS PLAUSIBLE WITH THE AMOUNT OF MOISTURE LEFT ACROSS THE AREA COMPARED TO WHAT WAS FORECAST. WEAK HIGH PRESSURE OVER THE WESTERN ATLANTIC WILL ALLOW A LIGHT WIND REGIME TODAY WHICH WILL IN TURN LEAD TO SEA BREEZE DEVELOPMENT. STORM MOTION TODAY IS EXPECTED TO BE GENERALLY TOWARD THE SOUTHEAST THIS AFTERNOON AND DUE TO ACTIVE SEA BREEZE BOUNDARIES, A MOIST AIRMASS, AND UNCAPPED FORECAST SOUNDINGS DURING MAX HEATING, ALL OF THE EAST COAST METROS AND MOST OF THE INTERIOR CAN EXPECT NUMEROUS AFTERNOON SHOWERS AND THUNDERSTORMS. THIS SITUATION WILL LIKELY REPEAT ITSELF ON TUESDAY, BUT STORMS ARE EXPECTED TO BE MORE CONCENTRATED OVER THE SOUTH HALF OF THE AREA WITH A MORE SOUTH BOUND STORM MOTION. BY WEDNESDAY THE WEAK RIDGE OF HIGH PRESSURE IS EXPECTED TO GIVE WAY TO AN AREA OF LOW PRESSURE THAT IS EXPECTED TO DEVELOP OVER NORTHERN FLORIDA. AT THIS TIME THE SURFACE TROUGH IS EXPECTED TO REMAIN NORTH OF SOUTH FLORIDA, BUT WITH AMPLE MOISTURE STREAMING NORTH AHEAD OF THE SURFACE LOW AND SEVERAL SHORT WAVES ROUNDING THE BASE OF AN UPPER LEVEL TROUGH ACROSS THE REGION SCATTERED STORMS WILL LIKELY OCCUR ACROSS THE AREA. IF THE GFS CONTINUES TO SHOW THIS SCENARIO, POPS MAY NEED TO BE BUMPED TO LIKELY, BUT NEED TO SEE MORE CONSISTENCY ON THE MODELS PART SINCE SUNDAYS 0Z RUN WASNT NEAR AS WET. THE WET FORECAST IS EXPECTED TO CONTINUE INTO THE WEEKEND WITH THE UPPER TROUGH REMAINING ACROSS THE STATE THROUGH FRIDAY AND POSSIBLY MORE TROPICAL MOISTURE WORKING IN BY SATURDAY. AVIATION...VFR ALL TERMINALS THOUGH RANDOM SHRA E GULFMEX MAY BRING TEMPORARY VCSH KAPF. VFR THROUGH 16Z ALL TERMINALS THEN AFTERNOON CONVECTION DEVELOPS.
