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 10, 7:11 AM EST, 57 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 811 AM EDT Mon Jul 10 2017 .AVIATION... VCTS conds continue from KMIA to KFXE with more shower and storm activity pushing onshore. Cloud bases associated with these storms have been near 2500 ft MSL. Expecting this activity to persist through 10/1800Z, before convection shifts towards the interior and western portion of the peninsula. An Atlantic sea breeze will push ashore aft 10/1500Z, 10-12 KT, then diminish by this evening. && .PREV DISCUSSION... /issued 439 AM EDT Mon Jul 10 2017/ DISCUSSION... TODAY THROUGH TUESDAY: The larger synoptic pattern remains fairly typical for summertime with the western Atlantic ridge axis extending across Central Florida both at the surface and aloft. The feature to watch over the next two days will be the upper level wave currently rounding the base of the ridge across Cuba and the Bahamas. This feature will also bring with it a modest increase in moisture, as seen on satellite, though much of this is likely to remain to our south and west. Convective evolution today and tomorrow looks fairly typical as well, with the ongoing morning showers and storms over the Atlantic affecting the east coast this morning, then activity shifting inland early afternoon as the east coast seabreeze develops. While prevailing flow remains easterly, the Gulf breeze looks to develop and move a little ways inland both afternoons. This will focus the best coverage just inland from the Gulf coast during the afternoons and evenings. 500mb temps are forecasted to dip to -8C to -9C as the upper level low transits later today and tomorrow. This may enhance the severity of afternoon activity, mainly on Tuesday, especially with the afternoon seabreeze collision towards the west side of the peninsula. WEDNESDAY THROUGH FRIDAY: The Western Atlantic ridge axis will strengthen and expanded westward into the Deep South mid to late week with deep easterly flow prevailing. Subsidence in between the waves on Wednesday will hold down rain chances, with the activity that initiates along the east coast seabreeze quickly moving west with the flow. The next significant wave, the remnants of the former TD 4, will track across the area on Thursday, with the slower ECMWF not moving the wave through until later on Friday. PWATs look to rise to well over 2 inches with the wave, leading to numerous showers with embedded thunderstorms, some likely heavy, through the day Thursday and possibly lingering into Friday. NEXT WEEKEND: The mid-range differences between the synoptic patterns depicted by the ECMWF and GFS continue into next weekend. While both show the Western Atlantic ridge retreating back to the east as troughing deepens across the Lower Mississippi Valley and Central Gulf, they vary slightly in the position and strength of the ridge. The GFS has a weaker, but further north ridge, with the ECMWF a little stronger but further south. The ECMWF keeps the winds more southerly and the local atmosphere a little more moist compared to the GFS, and therefore better rain chances across South Florida. Splitting the difference between the two keeps the region in a more typical summertime pattern with both seabreezes moving inland during the afternoons, with coverage a little higher than normal. MARINE...Easterly flow around 10 knots will prevail through the week into next weekend as the Western Atlantic ridge axis remains to our north. Several passing tropical waves may briefly enhance wind speeds to 10-15kts, especially over the local Atlantic waters. Seas will be 2ft or less over the Gulf and 2-3ft in the Atlantic, occasionally up to 4ft. Showers and thunderstorms can be expected over the waters each day, especially during the overnights and mornings. Coverage will be a little higher on Thursday and Friday. AVIATION...Atlantic coastal convection should diminish in the coming hours, with a resurgence later in the morning. The sea breezes should push inland focusing convection from east to west. Terminals could see sub-VFR conditions if directly impacted by convection. Convection should diminish later in the evening, though some could linger around APF and over the Atlantic waters. && .PRELIMINARY POINT TEMPS/POPS...
