NWS Miami, FL wrote its last area forecast discussion before the first event at Aug 6, 1:11 PM EST, 19 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 211 PM EDT MON AUG 6 2007 .DISCUSSION...CURRENT UPPER TROUGH AXIS OVER THE EXTREME S FLA PENINSULA CONTINUING TO HELP FIRE OFF CONVECTION IN NORTHERLY FLOW. INITIAL CONVECTION SEEMING TO GET STARTED ALONG SFC BOUNDARY NEAR CENT BROWARD COUNTY WHICH IS THEN BEING ENHANCED BY PALM BEACH SEA AND LAKE BREEZES. THIS CONVECTION WILL CONTINUE TO EXTEND SOUTH THROUGH THE AFTERNOON. SOUTH OF THIS AREA, E CST SEA BREEZE CLEARLY EVIDENT ON MIAMI RADAR BEGINNING TO SHOVE WEST THROUGH THE METRO AREA. THIS SHOULD HELP KEEP CONVECTION FORMING INLAND AWAY FROM THE COAST IN BROWARD AND MIAMI-DADE COUNTIES. LOOKING WESTWARD, CONVECTION SHOULD EXPAND OVER THE INTERIOR ZONES BUT SHOULD STAY EAST OF THE NAPLES AREA WITH THE NORTHERLY FLOW. ONCE THE TROUGH MOVES SOUTH OF THE PENINSULA, CONVECTION WILL BEGIN TO WIND DOWN WITH LOSS OF INSOLATION. IN ADDITION, 50H RIDGE THAT HAS A FIRM GRIP OVER THE SE U.S. WILL BUILD BACK ACROSS S FLA TUESDAY AND WEDNESDAY WITH SFC RIDGE ALSO BUILDING BACK IN FROM THE ATL. THIS WILL GIVE S FLA A DEEP EASTERLY FLOW WITH A RETURN TO SCATTERED CONVECTION DEVELOPING INTERIOR AND THEN MOVING TO THE W CST. POPS WILL HOWEVER NOT BE HIGHER THAN LOW SCATTERED AS UPPER RIDGE WILL KEEP A CAP ON ANYTHING MAJOR. IN THE EXTENDED, NO MAJOR MOISTURE IMPULSES WITH ANY CARIBBEAN WAVES STAYING SOUTH OF OUR REGION AS YET ANOTHER IN A SERIES OF 50H TROUGHS DIGS INTO THE EASTERN U.S. ALLOWING FOR THE UPPER RIDGE TO BUILD BACK TO THE CENTRAL PLAINS. THE LATEST MEX HOWEVER INCREASES POPS FOR THE WEEKEND BUT AM HAVING A HARD TIME JUSTIFYING THIS BASED ON THE LATEST GFS RUN SO WILL NOT CHANGE POPS FOR THAT TIME FRAME. && .AVIATION...THE EAST AND WEST COAST SEA BREEZES HAVE DEVELOPED AND WAS PUSHING SLOWLY INLAND EARLY THIS AFTERNOON. SOME SHOWERS WERE DEVELOPING ALONG THE EAST COAST SEA BREEZE AND SHOULD CONTINUE AS THE SEA BREEZE PUSHES INLAND. SO HAVE PUT VCTS IN THE TAF SITES FOR PBI...FLL...AND FXE FOR THIS AFTERNOON. REST OF THE TAF SITES SHOULD NOT SEE ANY ACTIVITY AS THE SEA BREEZES WILL BE INLAND BY THE TIME THE ACTIVITY HAS GOT STARTED IN THESE AREAS. THE ACTIVITY SHOULD BE DONE EARLY THIS EVENING AS THE HEATING OF THE DAY IS LOST. SO WILL HAVE NO WX IN THE TAF SITES AFTER 23Z. VFR CONDITIONS WILL ALSO PREVAIL THROUGH THE PERIOD ACROSS ALL OF THE SOUTH FLORIDA TAF SITES. THE ONLY EXCEPTION TO THIS IS DURING A SHOWER THAT COULD REDUCE THE VIS TO MVFR CONDITIONS FOR ABOUT 20 MINUTES OR SO THIS AFTERNOON.. BUT THE TIME IS TO SHORT TO PUT IN THE TAFS. && .MARINE...SFC PRESSURE GRADIENT WILL REMAIN VERY WEAK NEXT SEVERAL DAYS WITH SEAS AT MOSTLY TWO FEET OR LESS THROUGH THE FORECAST CYCLE. && .FIRE WEATHER...NO MAJOR CONCERNS ANTICIPATED WITH HIGH ENOUGH DEW POINTS KEEPING LOWEST AFTERNOON RH VALUES IN THE 40 TO 45 PERCENT RANGE. && .PRELIMINARY POINT TEMPS/POPS...
