AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 239 PM EDT FRI MAY 24 2013 .DISCUSSION... EAST COAST SEA BREEZE HAS STARTED THIS AFTERNOON AND CAN BE SEEN WELL ON RADAR. SCATTERED TO BROKEN CU FIELD HAS ALSO DEVELOPED ACROSS THE AREA AS TEMPERATURES HAVE SOARED INTO THE UPPER 80S TO LOW 90S. STILL BELIEVE ISOLATED SHOWERS AND THUNDERSTORMS SHOULD DEVELOP ALONG THE SOUTHERN PORTIONS OF THE AREA OVER THE NEXT FEW HOURS. STORMS THAT DEVELOP SHOULD BE ENHANCED BY A WEAK PRE-FRONTAL TROUGH LINGERING ACROSS THE EXTREME SOUTHERN PORTIONS OF THE AREA. 12Z MFL SOUNDING SHOWED FAIRLY STEEP MID LEVEL LAPSE RATES OFFSET BY FAIRLY DECENT CAPPING. A FEW MORE DEGREES OF HEATING SHOULD ERODE CAPPING ALLOWING THUNDERSTORMS TO DEVELOP ACCOMPANIED BY SEA BREEZE INTERACTIONS. MAIN THREATS WITH ANY STORMS WILL BE BRIEF HEAVY DOWNPOURS AND GUSTY WINDS. SHOWERS AND THUNDERSTORMS SHOULD DIMINISH LATER THIS EVENING WITH HEATING LOSS. BY SATURDAY A WEAK BACK DOOR COLD FRONT WILL PUSH THROUGH THE AREA BRINGING MUCH DRIER AIR TO THE SOUTH FLORIDA AREA WITH SLIGHTLY MILDER TEMPERATURES. PLEASANT CONDITIONS WILL PREVAIL THROUGH THE WEEKEND. DEEP MOISTURE WILL RETURN IN A BIG WAY THROUGH THE FIRST HALF OF NEXT WEEK AS A LARGE AREA OF MOISTURE SURGES TO THE NORTHWEST AND INTO THE SOUTH FLORIDA AREA FROM THE BAHAMAS. THIS WILL INCREASE CHANCES FOR SHOWERS AND POSSIBLE THUNDERSTORMS DURING THIS TIME FRAME. ANOTHER DEEP MOISTURE AXIS WILL THEN PUSH INTO THE AREA ON THE HEELS OF THE FIRST...THIS TIME ACCOMPANIED BY AN H5 LOW AND ASSOCIATED SURFACE TROUGH. MODEL SOUNDINGS DEPICT PWAT VALUES SURGING TO 2+ INCHES BY LATE THURSDAY. NEEDLESS TO SAY...PRECIPITATION CHANCES WILL LINGER THROUGH THE END OF THE WEEK. && .MARINE... THE PRESSURE GRADIENT WILL INCREASE ACROSS THE REGION OVER THE WEEKEND AS LOW PRESSURE BUILDS INTO THE ATLANTIC SEABOARD AND HIGH PRESSURE BUILDS INTO THE SOUTHEAST UNITED STATES.
