The episode as NWS MFL wrote it up.

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Miami, FL wrote its last area forecast discussion before the first event at Jul 1, 2:19 PM EST, 3 hours 41 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 319 PM EDT WED JUL 1 2015 .DISCUSSION... A DEEP EASTERLY FLOW HAS SET UP ACROSS SOUTH FLORIDA AS A RIDGE BUILDS BACK INTO THE REGION BOTH AT THE SURFACE AND ALOFT. THIS PATTERN WILL PERSIST FOR THE NEXT SEVERAL DAYS INCLUDING THE HOLIDAY WEEKEND WITH AFTERNOON SHOWERS AND THUNDERSTORMS CONCENTRATED OVER THE INTERIOR AND GULF COAST. A RATHER THICK SAL (SAHARAN AIR LAYER) WILL CONTINUE ACROSS SOUTH FLORIDA THROUGH THURSDAY GIVING THE SKY A MILKY OR HAZY LOOK. THIS IS ALSO EVIDENT ON THE 12Z MFL SOUNDING SHOWING VERY STEEP MID LEVEL LAPSE RATES AT 7.1C/KM. ALTHOUGH THE PWAT IS BARELY OVER 1.5", THE STEEP LAPSE RATES COULD FUEL A COUPLE OF STRONG STORMS LATE THIS AFTERNOON. THE PAST FEW RUNS OF THE HRRR HAVE SHOWN WHERE THE STORMS CURRENTLY ARE LOCATED AND THEN DRIFT TOWARDS THE NAPLES AREA LATE IN THE AFTERNOON. A FEW CELLS ARE CURRENTLY DEVELOPING JUST TO THE NORTHEAST OF NAPLES SO THIS SCENARIO SEEMS REASONABLE. ACCORDING TO THE NAVAL RESEARCH LAB MODEL, THE SAL WILL THIN SOMEWHAT ON FRIDAY AND SATURDAY BUT ANOTHER THICK LAYER WILL BE APPROACHING THE SOUTHEAST COAST EARLY NEXT WEEK AND MAY PERSIST INTO THE MIDDLE OF THE WEEK. FORECAST SOUNDINGS INDICATE PWAT IN THE RANGE OF 1.5-1.7" THROUGH THIS PERIOD SO STORM COVERAGE WILL GENERALLY BE AROUND 40-60% EACH DAY EXCEPT 20-30% ALONG THE EAST COAST. A COUPLE OF STRONG STORMS OVER THE INTERIOR ON THURSDAY AFTERNOON CANNOT BE RULED OUT WITH THE SAL STILL IN THE AREA. THE GFS IS SHOWING A MOISTURE SURGE ON FRIDAY AND SATURDAY AS A COUPLE OF TROPICAL WAVES PASS TO OUR SOUTH SO THERE COULD BE AN INCREASE IN COVERAGE THOSE TWO DAYS. HOWEVER, THE ECMWF DOES NOT SHOW THE MOISTURE SURGE SO COVERAGE WOULD REMAIN ABOUT THE SAME. ON THESE TWO DAYS AS THE WAVES MOVE THROUGH THE WESTERN CARIBBEAN, THE GFS DOES SHOW THE STEERING FLOW TO BACK MORE TO A SSE DIRECTION SO AFTERNOON STORMS COULD BE MORE CONCENTRATED AROUND THE LAKE REGION AND AWAY FROM THE GULF COAST BUT THE ECMWF CONTINUES THE DEEP EASTERLY FLOW. ALSO THROUGH THE NEXT SEVERAL DAYS, A GENERAL MID LEVEL CYCLONIC FLOW WILL CONTINUE ACROSS THE EASTERN U.S. WITH THE RIDGE OVER CENTRAL FLORIDA. BY EARLY NEXT WEEK, THE GFS SHOWS A STRONGER MID LEVEL TROUGH MOVING THROUGH THE CYCLONIC FLOW WITH A SURFACE LOW PRESSURE DEVELOPING ALONG THE CAROLINAS COAST AND VEERING THE STEERING FLOW ACROSS SOUTH FLORIDA TO A WESTERLY DIRECTION. HOWEVER, THE ECMWF DOES NOT SHOW THE DEEPENING TROUGH AND INSTEAD MAINTAINS AN EASTERLY FLOW ACROSS SOUTH FLORIDA. && .MARINE...
