The episode as NWS MFL wrote it up.
A weak tropical wave over Cuba produced scattered afternoon showers and thunderstorms across South Florida.
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 20, 1:13 PM EST, 3 hours 35 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 213 PM EDT SAT JUL 20 2013 .SHORT TERM (TONIGHT-MONDAY NIGHT)... A STRONG MID LEVEL RIDGE OVER THE MID ATLANTIC STRETCHES WEST TO ACROSS CENTRAL/SOUTH FLORIDA WITH MID LATITUDE TROUGHS MOVING ACROSS THE NORTHERN TIER OF STATES AND CANADA. A TROPICAL WAVE IS CURRENTLY MOVING THROUGH THE WESTERN CARIBBEAN SOUTHWEST OF JAMAICA AND THE NORTHERN EXTENT OF THIS WAVE IS LOCATED FROM THE EASTERN FLORIDA STRAITS AND INTO THE BAHAMAS. THIS HAS INCREASED CONVECTIVE ACTIVITY IN THAT REGION WITH HIGHER PWAT VALUES MOVING INTO SOUTH FLORIDA WHICH IN TURN IS HELPING TO ENHANCE CONVECTION. THE 12Z MFL SOUNDING WAS QUITE IMPRESSIVE AS REGARDS TO THE AVAILABLE CAPE BUT SO FAR THE STORMS HAVE BEEN SOMEWHAT SUPPRESSED DUE TO THE WEAK MID LEVEL LAPSE RATES ASSOCIATED WITH THE RIDGE AXIS. THE LOW LEVELS WERE VERY UNSTABLE HOWEVER AND THIS AIDED IN AN EARLY START TO THE CONVECTION PROCESS WITH STORM MOTION TO THE NORTHWEST DUE TO THE LOW LEVEL SOUTHEAST FLOW. THE FLOW BECOMES VERY WEAK TO LIGHT SOUTHWEST IN THE MID LEVELS IN RESPONSE TO THE RIDGE SO AS THE STORMS CONTINUE TO GROW, THE INTERIOR COULD GET QUITE ACTIVE LATER THIS AFTERNOON AS THE STORM MOTION BECOMES LESS THAN 5 MPH. THE WAVE WILL CONTINUE TO MOVE WEST OF THE AREA ON SUNDAY BUT AS MOISTURE CONTINUES TO LINGER ACROSS THE REGION WITH A WEAK SURFACE TROUGH BOUNDARY REMAINING IN PLACE, SCATTERED SHOWERS/THUNDERSTORMS ARE EXPECTED AGAIN BY LATE SUNDAY MORNING INTO THE AFTERNOON. DUE TO THE WAVE BEING FARTHER TO THE WEST, THE LOW LEVEL SOUTHEAST FLOW WILL BECOME SHALLOWER SO STORM MOTION WILL GO EVEN LIGHTER AND SEA BREEZE BOUNDARIES WILL LIKELY BE THE DOMINANT FOCUSING MECHANISM. AT THE SAME TIME, A SURFACE RIDGE WILL BUILD BACK ACROSS SOUTH FLORIDA BY SUNDAY AFTERNOON THROUGH MONDAY AND THIS COULD SUPPRESS CONVECTIVE ACTIVITY EVEN FURTHER WITH SEA BREEZE BOUNDARIES AGAIN BEING THE MAIN FOCUS FOR MONDAY AFTERNOON. .LONG TERM (TUESDAY-SATURDAY)... THIS SAME TREND WILL LIKELY CONTINUE THROUGH THE MIDDLE OF THE WEEK AS A DEEP LAYER RIDGE BECOMES FIRMLY ESTABLISHED AND FORECAST SOUNDINGS SHOW STORM MOTION 2 MPH OR LESS. A STRONG MID LEVEL TROUGH WILL BEGIN TO DEEPEN INTO THE EASTERN STATES BY THURSDAY INTO THE END OF THE WEEK AND INTO THE FIRST PART OF NEXT WEEKEND FOR A SLOW RETURN TO STORM MOTION STEERING STORMS BACK TOWARDS THE EAST COAST. FORECAST SOUNDINGS HOWEVER ARE NOT SHOWING A STRONG MOTION SO THE ENTIRE WEEK LOOKS AS IF VERY SLOW STORM MOTION WILL CONTINUE A THREAT FOR LOCALLY HEAVY RAINS WHERE EVER THE CONVECTION CAN SET UP. && .AVIATION... DEEP TROPICAL MOISTURE ASSOCIATED WITH A TROPICAL WAVE CONTINUES TO WORK ITS WAY INTO THE REGION. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO FORM INLAND OF THE ATLANTIC COAST AND GULF COAST SEA BREEZES AND ARE CURRENTLY NOT AFFECTING ANY OF THE SOUTH FLORIDA TERMINALS. HOWEVER THE LOCAL ATMOSPHERE IS UNSTABLE AND ANY ADDITIONAL CONVECTION THIS AFTERNOON AND EARLY EVENING COULD FORM QUICKLY IN THE VICINITY OF THE TERMINALS. THAT COUPLED WITH ANY OUTFLOW BOUNDARIES CAN ALSO AFFECT THE POTENTIAL FOR ADDITIONAL CONVECTION. WITH THE OCCURRENCE OF ANY SHOWERS/THUNDERSTORMS BRIEF SUB-VFR TO IFR CONDITIONS ARE POSSIBLE ALL TERMINALS INTO THE EARLY EVENING HOURS. && .MARINE... GENERAL EAST TO SOUTHEAST WIND IS EXPECTED THROUGH TUESDAY AT SPEEDS OF LESS THAN 15 KNOTS OUTSIDE OF SCATTERED SHOWERS/THUNDERSTORMS. THE WIND WILL BEGIN TO VEER TO A SOUTH OR SOUTHWEST DIRECTION LATER IN THE WEEK AS THE SURFACE RIDGE SHIFTS TO THE SOUTH. && .FIRE WEATHER...
