The episode as NWS JAX wrote it up.
Very high atmospheric moisture content with precipitable water values 1.9-2.1 inches in addition to forcing from active sea breezes under SW steering flow fueled severe storms and locally heavy rainfall during the late afternoon and evening.
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 May 22, 1:48 PM EST, 1 hour 52 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 248 PM EDT Mon May 22 2017 .NEAR TERM.../THROUGH TUESDAY/... The region will be between high pressure to the East and a frontal boundary to the Northwest Today into Tuesday. Most of Todays convection will initiate on the West and East coast sea breeze boundaries, with a convergence of these boundaries likely occuring between interstates I95 and I75 around 20z. With the flow generally from the Southwest, expect this area of convection then to move toward I95 corridor later this afternoon, before moving off the Eastern shore this evening. Could see showers and a few storms linger through the night Northwest closer to the frontal boundary. The overall pattern will remain nearly the same into Tuesday. However, a 500h short wave trough will move Southeast into the region in the afternoon. This energy, coupled with surface instability and sea breeze interactions will result in scattered to numerous showers and storms once again. The best chance for convection Tuesday afternoon will be over SE GA closer to the upper energy. && .SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/... TUESDAY NIGHT...There may some linger convection along the First Coast and Coastal SE Georgia during the early evening with some stratiform precip in the wake of the west coast sea breeze convection mainly north of I-10 and interior SE GA through mid evening. The convection will move well offshore during the late evening as well as the stratiform rainfall. A couple hours after midnight...increasing large scale ascent ahead of a large scale trough...supplemented by diffluent flow aloft is quite favorable to support widespread rainfall over the eastern Gulf of Mexico and Florida's Nature and Sun Coasts. This convection looks like it will push into the Suwannee Valley during the predawn hours and into interior SE GA and into NE Florida. There may be some initial heavy rain showers with embedded convection during the morning commute early Wednesday morning which could be round #1. WEDNESDAY AND WEDNESDAY NIGHT...On Wed, upper level trof over the Mid South will extend into the Gulf of Mexico driving a frontal boundary into the western Florida Panhandle and western Georgia early in the day. Deep layer southwesterly wind and speed shear will occur with surface winds strengthening at 15-25 mph with some higher gusts while higher pre-frontal moisture overspreads the area with precipitable water values 1.8" to 2.0". The deepness of the trough suggests that a band of convection ahead of the front could produce strong storms Wed afternoon into early Thu. The sounding profile suggests a nearly saturated atmosphere. Significant rainfall is possible, with Day 3 WPC rainfall totals of generally 2-3 inches, with substantially but locally higher amounts are very feasible perhaps requiring a Flood Watch Wednesday. Due to ample cloud cover and rainfall, instability does decrease, BUT shear does increase with SFC to 3km shear values at 35 knots. The wind profile will be unidirectional with ample CAPES of 1300-1600 J/kg. With this said, a couple rounds of strong to severe weather will be likely across the region throughout the day and into the evening hours ahead of the cold front, and along the front itself. The main threat from the stronger to marginally severe storms can be wind gusts of 45 to 65 mph, 1" hail with 5h temps at -10. SPC has southeast Georgia in a Marginal Risk and northeast Florida in a Slight Risk of severe weather on Wednesday. The convective activity will likely linger through most of the evening edging slowly eastward as the evening progresses with shear values still pretty heightened east of highway 301 with 40 knots of shear mid evening east of I-95 in NE FL. The NAM does show backing at the surface across northeast Florida with a hodograph indicating some good directional shear in the lowest 1 km early to mid evening as frontal feature moves into Big Bend Region. Hence, a isold tornado can not be ruled out. Highs Wednesday will generally range from upper 70s to lower 80s. Some clearing expected over inland southeast Georgia and the western Suwannee Valley by the predawn hours on Thursday as cold front situates across our southern tier counties in north central FL. Lows will fall to the lower 60s interior SE GA, and lows elsewhere will remain in the mid to upper 60s. .LONG TERM /Thursday through Memorial Day/... The upper trough axis shifts through the region by Thursday afternoon, with a surface cold front well ahead pushing east- southeast through the North Central southern tier zones by early morning. The heavy rainfall threat will also end Thursday morning behind the front. Drier air will filter into the region through the day as the cold front pushes southward, with much more pleasant dewpoints in the mid to upper 50s areawide by afternoon. Friday morning lows will be cooler in the mid/upper 50s inland and the low to mid 60s along the coast, around 5 degrees below normal. Highs are forecast to also be cooler in the mid 80s. Upper ridging will build northwest from the southwest Gulf late in the week and into the weekend. Weak surface high pressure will then build across central Florida through the end of the week and into the weekend, with dry conditions continuing. Moisture may begin to return Sunday and Monday, with 20-30% rain chances, highest across southeast Georgia. However, models are not in agreement on timing of moisture return this far out. Slightly below normal on Thursday will quickly rebound to above normal in the upper 80s to low 90s by the Memorial Day weekend, with lows in the mid 60s to lower 70s. && .AVIATION... Convection is expected to affect area TAF sites this afternoon into this evening. The convection will dissipate by around midnight, then redevelop Tuesday morning. Restrictions in addition to gusty winds can be expected in and near any storms. && .MARINE...High pressure will move from East of the region Today to the Southeast Tuesday and Wednesday. A cold front will cross area waters Wednesday night into Thursday. High pressure will build from the West Thursday night into Friday. This ridge will be East of area waters over the weekend. Rip Currents: Low risk expected on Tuesday as offshore flow develops. && .PRELIMINARY POINT TEMPS/POPS...

This Hazardous Weather Outlook is for Northeast Florida, Southeast Georgia and the Adjacent Coastal Waters. .DAY ONE...Today and Tonight... Scattered storms will develop early this afternoon on both the Atlantic and Gulf seabreezes. Thunderstorms will increase in both coverage and intensity as we go through the mid to late afternoon hours. Thunderstorms will become especially enhanced late in the afternoon as the two seabreezes come together, likely somewhere between Highway 301 and I-95. Isolated severe storms will be possible this afternoon and evening. The main threats will be damaging wind gusts, localized flooding, and intense/excessive lightning strikes. Storms will push offshore and weaken during the evening hours. Moderate risk of rip currents at northeast Florida beaches today. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday... A wet and stormy pattern will continue through Wednesday night. Multiple rounds of storms with locally heavy rainfall can be expected. Isolated storms could become Severe at times with damaging winds and large hail possible. Widespread beneficial rainfall is expected, however widespread heavy rainfall will be possible Tuesday night through Wednesday night and some localized flooding can be expected. .SPOTTER INFORMATION STATEMENT...
