AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 243 PM EDT WED JUL 18 2007 .DISCUSSION...STRONG SUBSIDENCE AND DRY AIR BEING FUNNELED THROUGH SOUTH FLORIDA BETWEEN THE UPPER RIDGE ACROSS NRN GULF AND THE TUTT LOW OVR WESTERN CARIB...HELPED TO KEEP MOSTLY SUNNY SKIES AND NO PRECIP OVER MOST OF THE EASTERN METRO AREAS WED AFTERNOON. ONLY EXCEPTION ON THE EAST COAST WAS INLAND PALM BEACH COUNTY WHERE SEA/LAKE BREEZES CONVERGED RESULTING IN ISOLATED SHWRS/TSTMS. OTHER SHOWERS DEVELOP OVER INTERIOR SECTIONS AND CONVECTIVE ACTIVITY WAS EXPECTED TO DEVELOP OVER THE WEST COAST/NAPLES AREA AS THE WEST COAST SEA BREEZE DEVELOP...THOUGH THAT HAD NOT HAPPENED AT THE TIME OF THIS WRITING. .TONIGHT THROUGH FRIDAY NIGHT...UPPER RIDGE WILL CONTINUE OVER THE GULF OF MEX AND THIS WILL KEEP SOME DEGREE OF SUBSIDENCE OVER THE LOCAL AREA. ATLC LOW LVL RIDGE WILL EXTEND WEST ACROSS SOUTH CENTRAL FLORIDA AND THIS WILL RESULT IN A WELL ESTABLISHED LOW LVL (BELOW 15KTF) EAST TO SOUTHEAST WIND FLOW. THIS FLOW WILL CONTINUE TO ENHANCE THE EAST COAST SEA BREEZE MAKING IT TO TRAVEL WELL INLAND BEFORE HAVING A CHANCE OF STARTING ANY AFTERNOON CONVECTION. IN ACT ANY CONVECTIVE ACTIVITY DURING THIS PERIOD (HOWEVER LITTLE THAT MAY BE) WILL TEND TO CONCENTRATE OVER INTERIOR AND WEST. WL ONLY INDICATE ISOLD/LOW SCT POPS. .SATURDAY THROUGH WEDNESDAY...AN AMPLIFYING MID LATITUDE TROUGH WILL DIG SOUTH ACROSS THE EASTERN PORTION OF THE COUNTRY KICKING THE UPPER RIDGE OUT OF THE AREA. THIS WILL PUT US UNDER SLIGHTLY MORE UNSTABLE CONDITIONS FOR AFTERNOON CONVECTIVE DEVELOPMENT. THE MEAN STEERING FLOW WILL ALSO CHANGE GRADUALLY AND BECOME MORE WESTERLY MEANING THAT CHANCES FOR RAIN COULD BE SIMILAR ACROSS ALL OF SOUTH FLORIDA. SO WILL INCREASE POPS TO SCT ACROSS ALL AREAS DURING THIS PERIOD. GFS STILL BRINGS A FRONTAL BOUNDARY ASSOCIATED WITH THIS MID LATITUDE TROUGH AS FAR SOUTH AS SRN GA/NORTHERN FLORIDA DURING THIS PERIOD AND THEN STALL IT THERE AS THE ATLC RIDGE STRENGTHENS AND THE PARENT TROUGH LIFT NORTHEASTWARD...KEEPING IT FROM REACHING FURTHER SOUTH. NOT SURPRISINGLY GFS TRIES TO DEVELOP A WEAK SFC LOW ALONG THE BOUNDARY BY MID WEEK AND MOVES NORTHEASTWARD. && .AVIATION...ATLANTIC COAST SEABREEZE HAS ALREADY PUSHED WEST OF ALL METRO PALM BEACH, BROWARD AND MIAMI-DADE AIRPORTS SO ONLY SCATTERED CUMULUS CLOUDS EXPECTED THERE FOR THE REST OF THE AFTERNOON AND EVENING. AIRCRAFT APPROACHES TO METRO ATLANTIC COAST AIRPORTS WILL PROBABLY BE BUMPY AS SHOWERS/THUNDERSTORMS ARE STILL EXPECTED OVER THE INLAND AND SOUTHWEST GULF COAST AREAS THE REST OF THE DAY. FOR KAPF, SEABREEZE CONVERGENCE WILL RESULT IN BEST CHANCES FOR FIRST ROUND OF SHOWERS/THUNDERSTORMS THROUGH 20Z BUT WILL BE MOVING INLAND WITH MOST CONVECTION EXPECTED INLAND OF THE AIRPORT 20Z-23Z. LOCAL WRF MODEL DOES SHOW WESTWARD MOVING THUNDERSTORMS INTO THE KAPF AREA AGAIN AFTER 23Z. DIURNAL CONVECTION WILL DIE DOWN AFTER 01Z BUT NOCTURNAL MARINE SHOWERS WILL BE DEVELOPING AND MOVING ONSHORE METRO ATLANTIC COAST AIRPORTS AFTER MIDNIGHT ONCE AGAIN. && .MARINE...ATLC RIDGE WILL KEEP SFC WINDS FROM E/SE AT 15 KTS OR LESS AND SEAS 4 FEET OR LESS THROUGH THE ENTIRE FORECAST PACKAGE. && .FIRE WEATHER...NO PROBLEMS EXPECTED AS RH SHOULD REMAIN WELL ABOVE CRITICAL VALUES. && .PRELIMINARY POINT TEMPS/POPS...
