The drought which began in March across Southwest Florida was wiped out by days of very heavy rainfall and flooding, especially during the period of June 4-8. As much as 20 inches of rain fell during this period in the Big Cypress Preserve of Collier County, with widespread 5-15 inches over the rest of Collier County and parts of Hendry County.

The episode as NWS MFL wrote it up.
The drought which began in March across Southwest Florida was wiped out by days of very heavy rainfall and flooding, especially during the period of June 4-8. As much as 20 inches of rain fell during this period in the Big Cypress Preserve of Collier County, with widespread 5-15 inches over the rest of Collier County and parts of Hendry County. In Glades County, the heavier rainfall arrived a little later, prolonging the drought slightly in that area.
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 May 31, 6:49 PM EST, 5 hours 11 minutes earlier.
Area Forecast Discussion National Weather Service Miami FL 749 PM EDT Wed May 31 2017 .UPDATE... Sea breeze moved in earlier this afternoon enhancing some thunderstorms over portion of the interior and Lake Okeechobee. Latest short term models indicate most of the afternoon activity will gradually dissipate inland while it begins to pick up over the Atlantic waters tonight. Most of this activity remains offshore but gradually diminish before midnight. The temperatures will remain pretty warm overnight with lows in the upper 70s along the east coast metro areas and low 70s interior and west. No major updates necessary on the current forecast. && .PREV DISCUSSION... /issued 332 PM EDT Wed May 31 2017/ DISCUSSION... As daytime heating continues over the peninsula and sea breeze moves in, showers and thunderstorms will begin to develop as the afternoon progresses. Some drier air and slightly cold air aloft will allow for some afternoon strong thunderstorms which could be capable of producing small hail and gusty downburst winds. Otherwise, it should be a pretty typical early summer day across South Florida with afternoon thunderstorms in the interior propagating towards the west Gulf coast and Lake region late this afternoon and early evening. Heat indexes values will range between 101 to 103 over the southwest Gulf coast. Elongated ridge is observed on the latest water vapor imagery this afternoon while surface high pressure slowly progresses eastward into the Atlantic waters. Light southeasterly flow will continue for the rest of the week with relatively moist atmosphere. A plume of deep moisture stretching from the Bay of Campeche into the Florida peninsula will bring an increase in deep tropical moisture into South FL Friday through the weekend. Precipitable water values will rise from 1.8 to 2 inches which is well above normal for this time of the year. Expect afternoon convection to develop over the mainly the interior regions with sea breeze collisions and outflow boundaries dominating storm initiation. The main threats from these storms will be brief heavy rain, cloud to ground lightning, and erratic gusty winds. High temperatures will remain near the 90s along the coast and interior but possible thunderstorm activity could lower the temps to the mid 80s. Guidance decreases maximum highs by a few degrees. Heat indexes will remain below 100 Friday through early next week. MARINE... Broad surface high pressure will continue to produce east southeast winds today, mainly around 10 to 15 KT. Winds over inner Gulf waters may turn westerly this afternoon, due to the Gulf breeze development. Wave heights will generally range from 1 to 2 feet. Expect a slight chance of showers and thunderstorms through Thursday, especially at night. The threat of thunderstorm activity increases Friday through this weekend, as deeper moisture moves over the region. AVIATION... Convection is expected to potentially affect APF later this afternoon though confidence is not high enough at this issuance to include any restrictions at any sites. The east coast terminals should see storms stay well west of them. Overnight, wind will become lighter and more variable. Wind will pick up after sunrise on Thursday. && .PRELIMINARY POINT TEMPS/POPS...
