NWS Miami, FL wrote its last area forecast discussion before the first event at Jun 15, 6:38 PM EST, 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 738 PM EDT SAT JUN 15 2013 .AVIATION... GENERALLY QUIET NEXT 48 HOURS IN STORE FOR TERMINALS...WITH ONLY ISOLATED SHOWERS EXPECTED SUNDAY AFTERNOON. VFR CONDITIONS WILL PREVAIL WITH MAINLY SCATTERED CU BELOW CI DEBRIS. LIGHT WINDS TONIGHT WILL BECOME ESE AT 10 KNOTS ON SUNDAY. GULF BREEZE SHOULD REACH KAPF BTWN 16-19Z SUNDAY...TRANSITIONING WINDS TO WSW AROUND 10 KTS. && .PREV DISCUSSION... /ISSUED 202 PM EDT SAT JUN 15 2013/ DISCUSSION... HIGH PRESSURE BUILDING OVER THE AREA, HAS ALLOWED THE UPPER ATMOSPHERE TO WARM AND DRY OUT SOME. THIS HAS INHIBITED ANY CONVECTIVE CELLS SO FAR TODAY. THE GFS KEEPS ANYTHING THAT IS ABLE TO DEVELOP, NEAR THE LAKE REGION. THE ECMWF IS NOT MUCH DIFFERENT. WITH LAPSE RATES LOWER THAN YESTERDAY, AS WELL AS PWATS DROPPING TO BELOW 1.5 INCHES, THIS IS BELIEVABLE. THE HRRR IS SHOWING CONVECTION TRYING TO FIRE IN THE WESTERN HALF OF THE CWA THIS EVENING, BUT AM NOT BITING OFF ENTIRELY ON THIS SCENARIO. HAVE KEPT LOW END CHANCE POPS OVER GLADE/HENDRY/AND COLLIER COUNTIES, AND SLIGHT CHANCE OVER MUCH OF THE REST OF THE CWA, BUT THIS MAY WELL EVEN BE OVERKILL TODAY. BUT, ONLY TIME WILL TELL. IF IT IS NOT ABLE TO GO TODAY, IT WILL PROBABLY HAVE A HARD TIME GOING TOMORROW AS WELL, AS CONDITIONS WILL ONLY BE DRIER, WITH A SOMEWHAT STRONGER UPPER LEVEL HIGH. HAVE KEPT LOW END CHANCE OVER THE GULF COAST FOR TOMORROW WITH THIS PACKAGE, BUT AGAIN, THAT MAY BE TOO HIGH. THE HIGH CONTINUES FOR THE BEGINNING OF THE WEEK IN THE UPPER LEVELS. IN THE LOWER LEVELS, HOWEVER, THE BERMUDA HIGH STRENGTHENS ONCE AGAIN, BRINGING A MORE EASTERLY FLOW BACK TO SOUTH FLORIDA, AND THEREFORE INCREASING MOISTURE. SO, THE GULF COAST WILL KEEP CHANCE POPS INTO AT LEAST MID NEXT WEEK AND PROBABLY THROUGH THE END OF THE WEEK, BY WHICH TIME, MORE OF SOUTH FLORIDA MAY SEE CONVECTION FIRING. THERE IS A TROPICAL WAVE THAT MODELS SHOW WILL BE WELL TO THE SOUTH. IF IT KEEPS THAT TRACK, IT SHOULD NOT HAVE AN IMPACT ON SOUTH FLORIDA WEATHER. IF IT DOES COME CLOSER, IT WILL, OF COURSE, CHANGE THE FORECAST TO MOST LIKELY ADDITIONAL COVERAGE OF SHOWERS AND THUNDERSTORMS FROM MID TO LATE NEXT WEEK. MARINE... CONDITIONS SHOULD REMAIN FAIRLY QUIET INTO THE BEGINNING OF THE WEEK. THE BERMUDA HIGH IS FORECAST TO STRENGTHEN, WHICH COULD ALLOW SEAS TO BUILD BY MID WEEK. OTHERWISE, EASTERLY WINDS WILL KICK IN BY THE BEGINNING OF THE WEEK FOR THE ATLANTIC WATERS. THERE IS A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS EACH DAY. FIRE WEATHER... THERE IS AN UPPER LEVEL RIDGE THAT IS BUILDING OVER SOUTH FLORIDA. THIS SHOULD LEAD TO INCREASING STABILITY FOR A COUPLE OF DAYS. THE BERMUDA HIGH WILL STRENGTHEN FOR THE BEGINNING OF THE WEEK, ALLOWING AN EASTERLY FLOW TO BEGIN TO BEING MORE MOISTURE BACK INTO THE AREA, AND THUS MORE CONVECTIVE ACTIVITY NEXT WEEK. && .PRELIMINARY POINT TEMPS/POPS...
