The episode as NWS JAX wrote it up.
Stationary boundary across the I-10 corridor lifted northward as a warm front on Easter day. Behind the front, substantial surface heating, cold temperatures aloft, and an unstable air mass resulted in strong to severe thunderstorms developing along the inland moving sea breezes for portions of northeast FL in the afternoon. Severe thunderstorms produced large hail up to 2 inches in the vicinity of Nocatee and Palm Valley in northern St. Johns County and Palm Coast in Flagler County along the active Atlantic sea breeze boundary. A severe thunderstorm also downed several trees in Ocala due to a mircoburst.

NWS Jacksonville, FL wrote its last area forecast discussion before the first event at Apr 17, 12:51 PM EST, 24 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 151 PM EDT Sun Apr 17 2022 .AVIATION... [Through 18Z Monday] Scattered to numerous showers and storms are expected this afternoon into the evening hours and have put TEMPO groups with MVFR at times. Some of the storms could be strong with gusty winds and heavy rainfall. Southwest to west winds will prevail west of coastal terminals. East coast sea breeze will affect the coastal TAFs this afternoon. By late evening, the bulk of the convection is expected to lift northeast of the area. Cold front will move southeast across terminals during the predawn hours and early morning hours Monday. && .PREV DISCUSSION [1011 AM EDT]... .NEAR TERM [Today Through Tonight]... Sfc analysis shows a weak convergence zone from the SC coast southwest into southeast GA to the FL panhandle. A cold front was noted from VA to central NC to nrn AL/MS. A shortwave disturbance is moving through the forecast area and will support isolated to scattered convection, mainly north half of the forecast area, through early morning and move east in the mean 0-6 km flow at 10-15 kt. As the shortwave leaves the area by early aftn, additional weak disturbances will move into the area in the prevailing 15-20 kt westerly flow in the mid levels. The weak convergence zone looks to be near the I-10 corridor midday then lift northward by late aftn, with the sfc cold front to our north likely reaching near the Altamaha River by this evening. An area of low pressure around 1014 mb is likely to form along the front over southern GA, just to the northwest of our zones. The aforementioned boundaries combined with ample moisture with PWATS of about 1.5 inches and peak CAPE values of 2000-2500 J/kg will focus showers and thunderstorms during the day. Additionally, west and east sea breezes will initiate isolated to scattered convection as early as noon-1 pm. The highest chances of showers and storms will be from along and east of Highway 301 corridor in northeast FL, and generally all of our southeast GA zones. Will have close to the 60-70 percent range for these areas, with lower values closer the 30-50 percent range for the I-75 corridor. Bulk shear values up to 25 to 35 kt are sufficient for a few strong or even severe storms. The shear may be more enhanced along the zones east of Highway 301 given the Atlantic sea breeze boundary. Localized heavy rainfall/flooding possible given the fairly high CAPE values and enhanced moisture pooling. Given the instabilty and shear, SPC has placed a marginal risk of severe storms generally along and north of the I-10 corridor. Tonight, the cold frontal boundary near the Altamaha will likely lift northward overnight as a more dynamically supported sfc low develops over MS/AL. Lingering instability along with t-storm outflows and sea breezes support scattered to possibly numerous showers and t-storms ongoing at the start of the evening hours especially the eastern zones. A line of showers and storms may develop early evening over south and central GA and possibly enter the GA zones, then move offshore after midnight. This latter scenario is a bit uncertain given model disagreement with the timing and extent of this convection. By late in the night, the bulk of the convection is expected to lift northeast of the area. For temps, highs temps today mainly in the 80s, with some locations over inland northeast FL flirting with ~88-90 where a prevailing southwest-west wind is expected and less cloud cover. Lows tonight will be in the 60s again in the relatively warm and humid airmass ahead of the cold front. .SHORT TERM...[Monday through Wednesday]... Surface low will be over southern GA early Monday morning, located in the base of a 500 mb trough. The surface low will track east northeast in the upper trough through the morning, with the associated cold front moving east across forecast area. While much of the energy with this system will pass to the east Monday morning, troughing will linger into the afternoon. A gradual decrease in precipitation chances anticipated Monday afternoon from west to east. Temperatures will trend above normal Monday, as best cold advection occurs Monday night, as high pressure builds from the northwest. With the building high, skies will clear from west to east through the night, with noticeably drier air advecting in. Lows in the 50s are expected. Between the exiting low pressure system, and building high, the pressure gradient will be fairly tight. The combination of the gradient, and subsidence in the cold advection will lead to elevated winds Monday night into Tuesday morning. The gusty winds will be most noticeable along the coast, due to flow across coastal waters. The high will build more toward the north on Tuesday into Tuesday night, then toward the northeast for Wednesday. Dry air will be in place during this time, but clouds will begin to increase from the east toward Wednesday, due to increasing onshore flow. With the onshore flow a breezy day is expected for Wednesday near the coast. Temperatures will be below normal on Tuesday, with coastal locations barely reaching 70. A below normal night is anticipated for Tuesday night, but a wide variation in lows is expected due to northeast flow. Over interior areas lows in the mid to upper 40s is expected. Closer to the coast, lows in the mid to upper 50s are forecast. Temperatures will be a bit warmer on Wednesday, but there will be a wide variation in readings from east to west due to onshore flow. Highs well inland around 80 are expected, while highs near the coast will be in the 70 to 75 range. .LONG TERM...[Wednesday night through Saturday]... High pressure will be northeast of the region through this period. This will result in continued onshore flow. Moisture will gradually increase, with a few coastal showers possible by the weekend. With this flow, it will be breezy near the coast each afternoon. Temperatures will trend near to a little above normal this period. Readings will be coolest during the day, and warmest at night near the coast due to the onshore flow. .MARINE... Light south and southwest winds expected this morning but will shift to the southeast this afternoon due to the sea breeze. The sea breeze and elevated daytime instabilty will lead to a chance of thunderstorms this afternoon through tonight. The low to mid level west flow will take these storms into the nearshore and possibly offshore waters and may contain strong gusty winds. A cold front will move through the waters Monday evening, shifting winds to the north and northwest. SCA conditions look likely beginning late Monday evening, and continues into Tuesday. While winds may diminish Tuesday, seas will be elevated. An onshore flow develops by mid week creating SCEC and SCA conditions for the area waters. Rip Currents: Surf near 2 to possibly 3 ft will decrease a bit today but still have moderate risk of rip currents and as the flow turns onshore with the sea breeze. Generally low risk for Monday with offshore flow and slightly lower surf heights. Things change to higher rip current threats Tuesday and especially Wednesday due to increased north then northeast- east winds/increased surf. .FIRE WEATHER... Some areas with low dispersion expected today, but area high dispersions look likely for Monday and Tuesday. Much drier air filters in on Tuesday behind the departing cold front, which moves through Monday evening/night. .HYDROLOGY... Minor flooding along the Santa Fe at Three Rivers Estates forecast to continues to drop and be below flood stage late this coming week. Portions of the Altamaha River has minor flooding with levels near moderate flooding at Baxley. && .PRELIMINARY POINT TEMPS/POPS...
