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 Jun 12, 8:05 AM EST, 4 hours 49 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 905 AM EDT WED JUN 12 2013 .UPDATE... MID/UPPER LEVEL TROUGH OVER SOUTH-CENTRAL FLORIDA THIS MORNING WILL BE THE PRIMARY FEATURE AFFECTING OUR AFTERNOON CONVECTION TODAY. MORNING SOUNDING DATA SHOWS 500 MB TEMPS IN THE -9C RANGE ACROSS CENTRAL/SOUTH FLORIDA, BUT WITH THE MID/UPPER TROUGH MOVING SOUTH, EXPECT COLDER AIR ALOFT WITH MODEL SOUNDINGS SHOWING -10C AT 500 MB THIS AFTERNOON. ADDING TO THE POTENTIAL INSTABILITY IS AN UPPER LEVEL WIND MAX AROUND 50 KTS MOVING ACROSS THE SE GULF AND STRAITS OF FLORIDA, PLACING THE SOUTHERN FLORIDA PENINSULA IN THE DIFFLUENT EXIT REGION, AS WELL AS SOME MOISTURE POOLING IN THE LOWER TO MID LEVELS OVER FAR SOUTH FLORIDA. ALL THIS POINTS TO AN ACTIVE AFTERNOON OF CONVECTION ACROSS MUCH OF THE AREA WITH THE POTENTIAL FOR STRONG TO EVEN BORDERLINE SEVERE STORMS. MAIN FOCUS OF ACTIVITY WILL BE INITIALLY OVER THE INTERIOR AND WESTERN SUBURBS OF SE FLORIDA AROUND 1-2 PM, THEN GRADUALLY SHIFTING TO THE SW GULF COAST BY LATE AFTERNOON AS THE STEERING FLOW BECOMES NE TO SW.
