The episode as NWS JAX wrote it up.
Short wave trough pivoting across the local area downstream of a 500 mb trough axis enhanced daily sea breeze storms that produced wet downbursts across the area combined with high moisture and diurnal instability.
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 Jacksonville, FL wrote its last area forecast discussion before the first event at Jun 9, 10:21 AM EST, 59 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 1121 AM EDT Sun Jun 9 2019 ...FEW STRONG THUNDERSTORMS POSSIBLE ALONG THE I-95 CORRIDOR THIS AFTERNOON... .Update... Late morning surface analysis depicts slow moving and weakening low pressure (1010 millibars) over the Tennessee Valley, with a secondary wave of low pressure developing along a north-south oriented stationary frontal boundary positioned over western portions of the Florida panhandle. Aloft...a synoptic scale trough extending from the western Great Lakes to the northeast Gulf of Mexico is in the process of shearing out as a longwave trough digs through the northern Plains states, massive ridge remains locked in place over Mexico and Deep South Texas and ridging remains in place over the Mid-Atlantic states and the eastern Great Lakes. The southern portion of the large trough is beginning to cut off over the Florida panhandle and the northeast Gulf of Mexico, which has strengthened convergent low level southwesterly flow over the northeast Gulf of Mexico and along the Florida Big Bend and Nature coasts, resulting in widespread convective development along and west of Interstate 75 this morning. Activity has been weakening as it moved east of I-75, but breaks in the morning cloud cover have allowed ML CAPE values to climb to 1500-2000 j/kg late this morning for locations along and east of U.S. Highway 301, where convection is developing and strengthening west of Palatka. The morning sounding at Jacksonville revealed a 500 millibar near 20,000 feet) temperature of nearly -9 degrees Celsius and a rather steep lapse rate between 850-650 millibars (5,000-12,000 feet). Temperatures at 15Z have reached the mid 80s for locations east of U.S.-301, with rain-cooled temperatures generally in the mid 70s over the Suwannee Valley, north central Florida and portions of inland southeast Georgia. Dewpoints were in the 70s region-wide. Convective coverage should continue to increase late this morning and early this afternoon for locations along and east of U.S.-301 in Florida, with activity also expected to increase from southwest to northeast across southeast Georgia. A few strong thunderstorms will be possible east of U.S.-301 this afternoon, with activity pulsing and possibly producing wet microbursts that could result in isolated pockets of 40-55 mph wind gusts as activity moves towards the beaches by mid-afternoon. The Atlantic coast sea breeze will probably not move very far inland today given a tightening pressure gradient and breezy southerly low level winds. Localized flood concerns are possible over the Suwannee Valley and north central Florida as short-term, high resolution guidance indicates that another round of convection will develop along the Big Bend and Nature Coasts by late afternoon and will move inland. Highs may approach 90 for locations along and east of I-95 before convection arrives early this afternoon, while highs will be held in the 80s elsewhere. Convection should decrease from southwest to northeast this evening, with the next round likely developing along the Florida Big Bend and Nature Coasts after midnight and spreading into the Suwannee Valley and north central Florida during the predawn and early morning hours on Monday. Lows tonight will remain in the muggy 70s area-wide. && .Aviation... Periods of IFR ceilings will be possible this afternoon at GNV, where widespread showers and embedded thunderstorms will impact the terminal through around 21Z. Convection will approach the Duval County terminals and SGJ after 16Z, with tempo IFR conditions and gusty winds possible during heavier downpours. VFR conditions at SSI should prevail through at least 18Z, with convection likely arriving towards 19Z, with tempo IFR conditions and gusty winds possible through around 22Z. VFR conditions should re-develop at the regional terminals after 22Z, with some lingering MVFR conditions possible at GNV as additional convection develops west of the terminal late this afternoon. Outside of convection, southerly surface winds will remain sustained at 10-15 knots through 23Z. && .Marine... Low pressure over the Tennessee Valley this morning will accelerate northward over the eastern Great Lakes states, while another weak low pressure center developing over the Florida panhandle will move slowly northeastward across south Georgia on Monday night and Tuesday. Numerous showers and thunderstorms over the Suwannee Valley and north central Florida will move northeastward this afternoon, reaching the near shore waters by the mid to late afternoon hours. Outside of thunderstorm activity, our local pressure gradient will tighten slightly today as low pressure develops to our west, and south-southwesterly winds will strengthen to near 15 knots and will then likely increase to Caution levels of 15-20 knots this evening. Showers and thunderstorms will continue to periodically impact the coastal waters through at least mid-week as south to southwesterly winds prevail. Seas of 2-3 feet will prevail near shore, with 3-4 foot seas offshore. Low pressure will then move northeast along the eastern seaboard beginning on Wednesday night, resulting in a frontal boundary moving across the Georgia waters and then stalling over the northeast Florida waters late in the week. Southwesterly winds will likely surge to Caution levels in the offshore waters ahead of the front on Wednesday evening. Rip Currents: An 8-9 second period east-southeasterly ocean swell will continue at area beaches during the next several days, which will combine with a southerly long shore current to create a moderate risk at area beaches through at least Monday. && .PRELIMINARY POINT TEMPS/POPS...
