The episode as NWS JAX wrote it up.
Tropical airmass extending across the region from the low pressure center along the GA/SC coast with precipitable water of 2 inches and diurnal heating developed numerous to widespread shower and storm activity over northeast Florida. Activity was focused along the Atlantic and Gulf sea breezes as they shifted inland in the afternoon especially across the I-95 corridor where the boundaries later merged. Training storms and heavy downpours led to street flooding in Jacksonville Beach, Florida.
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 Jul 1, 12:45 PM EST, 45 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 145 PM EDT Fri Jul 1 2022 .AVIATION... [Through 18Z Saturday] Numerous slow-moving storms building throughout the forecast area moving in a west to east pattern, reaching sites along the eastern portion of the CWA this afternoon. Main threats with storms are localized flooding and variable wind gusts of up to about 25 to 35 knots. Winds will be out of the S-SW for inland areas and out of the E for sites affected by the Atlantic coast sea breeze. Widespread storms will become dispersed overnight with mild winds setting in through Saturday morning. Renewed bouts of convection are expected to develop on Saturday near the end of the forecast period. && .PREV DISCUSSION [954 AM EDT]... .NEAR TERM [Through Tonight]... Skies are partly cloudy near the coast and mostly clear farther inland this morning as an inverted trough lifts slowly northward towards the GA/SC coast with unsettled weather over the Atlantic waters as showers and storms continue over the Atlantic offshore waters thanks in part to shortwave energy traversing over the waters adding extra lift over the region. Some patchy fog has developed intermittently over inland areas where winds have calmed overnight and where storms from yesterday produced up to 2-4 inches locally in some spots. Rich moisture remains over the area as the 00Z sounding last night measured 2.12 inches which is in the 90th percentile for the start of July. The prior rainfall and very moist airmass over the region are giving us humid conditions you may notice this morning when you step out the door with dewpoints in the low to mid 70s while lows inland have fallen into the 70-75F range with 75-80F readings near the coast. After sunrise, patchy fog should quickly burn off by an hour after sunrise as the sun rises quickly with showers near the SE GA coast lifting slowly north to northeast. Skies will be partly to mostly cloudy through late morning, then become increasingly cloudy as the Atlantic and Gulf coast seabreezes merge inland this afternoon with the Gulf coast seabreeze more dominant as flow in the low levels spiral counter clockwise around the inverted trough lifting north to northeast of the area yielding numerous to widespread showers and thunderstorms this afternoon. The best focus for storms will be along just east of Highway 301 into the the St Johns river basin where the seabreezes/river breezes will merge early this afternoon with subsequent storm outflow collisions that, aided by shortwave energy still over the region, will initiate new storm cells through late afternoon that will drift into the the I-95 corridor towards early evening thanks to weak W to SW steering flow in place south of the lifting inverted trough. The weak flow pattern aloft and warm mid level temperatures will limit severe weather threat due to poor lapse rates, locally heavy rainfall potential, especially over areas that received 2-4 inches of rain yesterday and also over urban and low lying areas with poor runoff. Highs will be near to slightly below normal over SE GA with upper 80s under mostly cloudy skies and near normal over NE FL areas where less clouds early will allow highs to bump up to around 90F. Tonight, numerous thunderstorms will drift from the I-95 corridor early this evening off the coast and into the Atlantic waters by the midnight hour as the inverted trough lifts NNE of the area towards coastal SC. Multilayer debris clouds will remain and keep skies mostly cloudy overnight with humid conditions after the rainfall and light southerly winds 5-10 mph at the coast and near calm inland that will turn southwesterly towards dawn. Patchy fog will be possible over areas that receive rainfall with lows in the low/mid 70s. .SHORT TERM [Saturday Through Sunday]... Saturday...The Bermuda-Azores Ridge noses back across the forecast area with the ridge axis oriented across north Florida. There will be some weak troughing across southeast Georgia extending into the Suwannee Valley. With a southerly flow pattern both surface and aloft the Atlantic sea breeze front convection will be pinned close to the coast, east of U.S. 17. The Gulf sea breeze will interact with the trough across southeast Georgia. The Gulf convection will push east intersecting the Atlantic sea breeze front for some much needed rainfall along the Atlantic coastal areas. POPS will be in the 70 to 80 percent range Saturday afternoon and evening. Overnight the trough axis will be oriented along the Fl-GA State line with some scattered convection continuing past midnight. Sunday...The synoptic pattern will remain very similar to Saturday with the ridge axis a bit further inland and sea breeze front convergence across the interior areas. Once again some overnight convection is possible along the trough axis near the FL-GA State line. POPS will again max out in the 70-80 percent range but a bit further inland between the St Johns River and I-75. High temperatures will be in the 86 to 91 range with lows in the lower 70s inland and the mid 70s along the coast and St Johns River. .LONG TERM [Monday Through Friday]... The ridge axis begins to shift west on Monday and Tuesday with a distinct high pressure center located over the lower Mississippi River Valley Wednesday and Thursday. Afternoon and evening convection will continue over the interior areas on Monday and Tuesday gradually diminishing and shifting toward the Gulf Coast sea breeze front for the latter two days. High temperatures will gradually increase through the period reaching the mid 90s by Thursday. Lows will be in the mid 70s inland and the upper 70s along the coast and St Johns River. .MARINE... An inverted trough over the coastal waters will slowly lift northward to northeastward through today with an increase in southerly winds late this afternoon into late tonight that will lead to exercise caution conditions over the waters. High pressure will be northeast of the region through the weekend. The high then shifts farther east and extend a ridge axis over the area through next week. Rip Currents: Moderate risk expected at all area beaches through Saturday .HYDROLOGY... Widespread rainfall amounts of at least one inch is expected through this evening from the high coverage of thunderstorms as a inverted coastal trough and energy aloft enhance coverage of showers and thunderstorms today, especially along and east of Highway towards the coast. Locally heavier rainfall totals are possible with a threat for localized flash and urban flooding due to the slow storm motions this afternoon and evening, especially over locations that received 2-4 inches of rain from yesterday. && .PRELIMINARY POINT TEMPS/POPS...
