The episode as NWS MFL wrote it up.
Upper level trough across the area will allowed for enough instability to produce isolated to scattered afternoon showers and thunderstorms. With cold temperatures aloft environmental conditions supported the potential for strong downburst winds with some of the stronger convection that develop. A severe storm developed in Palm Beach County causing some wind damage and hail.
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 11, 12:24 PM EST, 2 hours 13 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 124 PM EDT Tue Jun 11 2019 .AVIATION... Convective initialization is already ocurring across the area. A few SHRA have also devleoped over the east coast. While the majority of the TSRA should be along the western edge of the east coast metro area, it is highly likely they will be close enough to impact the TAF sites, thus keeping the VCTS in the TAFs. Conditions should improve this evening. by tomorrow afternoon, another round of TSRA is possible, so a prob30 group has been added for MIA and FLL. && .PREV DISCUSSION... /issued 803 AM EDT Tue Jun 11 2019/ UPDATE... Have updated the forecast with the newest ensemble of hi-res models. They move the highest PoPs to the Lake region, and northern Palm Beach County. They hold most of the activity off until after 18Z today. However, they are still possible across the area, and some isolated convection could initiate later this morning. Some of the storms could become strong with downbursts of around 45 to 50 mph and funnel clouds. Over the water, waterspouts may be possible, especially where any outflow boundaries collide. PREV DISCUSSION... /issued 301 AM EDT Tue Jun 11 2019/ DISCUSSION... Upper level troughing that has influenced South Florida weather will continue to weaken today. This weakening is denoted on water vapor imagery by pockets of drier air wrapping around it's periphery. Correspondingly, satellite derived PWATs characterized by values around 1.5" (lower than previous days), are advecting north across the area. However, model derived PWATs depict this drop to be fairly short lived with values closer to 2.0" returning through the afternoon. This brief decrease in available atmospheric moisture could help suppress convective initiation until later in the afternoon and support more scattered coverage, compared to the more numerous-widespread pattern experienced the last few days. Through the remainder of the week, the remnant shortwave is expected to become absorbed by a longwave trough amplifying across the eastern CONUS and lift towards the NE. Global models depict a surface low developing along a frontal boundary that is currently draped to our north across the FL panhandle and extending into the southeastern CONUS. This surface feature will depart with its upper level counterpart and aid in pushing the frontal boundary south before becoming stationary along Central Florida and subsequently washing out. Southwesterly winds look to prevail during this time and allow for deep moisture to remain in place with PWATs climbing back above 2.0". These values are near the 75% and 90% moving averages for this time of year. Collectively, this will translate in the persistence of an unsettled pattern with development of afternoon showers and thunderstorms each day, favoring the east coast and Lake regions. The pattern aloft looks to become a bit more zonal by the beginning of the weekend, with a surface ridge building to our north. This will help shift the steering flow back out of the east and southeast. Despite the return of high pressure, lingering moisture should remain sufficient enough to provide plentiful buoyancy across the area and keep rain chances elevated through early next week. Coverage of showers and storms should shift back across the interior with a more dominate east coast sea breeze given the change in wind direction. All in all, this wetter pattern is here to stay through the forecast period. Given the considerable amount of rainfall already accumulated, areas with poor drainage could experience localized flooding and ponding of water. Temperatures will should also continue to run a few degrees above climatological average before moderating back to near normal through the weekend as a result of the returning easterly flow. Amid the warmer days, heat indices could reach triple digits across South Florida. MARINE... Showers and thunderstorms across the local waters continues to be the main boating concern the next few days. Frequent lightning, gusty winds, and locally higher seas can be expected in and near any storms. Otherwise, boating conditions will be relatively benign with light, south southwest winds 10kts or less and seas around 2 feet. && .PRELIMINARY POINT TEMPS/POPS...
