The episode as NWS JAX wrote it up.
Deep westerly flow prevailed over the region with an upper trough to the north and a ridge axis to the south. The anomalously moist airmass, with PWATs near 2.2 inches, remained over the region. Dense clouds were advected across much of the area Tuesday morning in the westerly flow. Cloudiness limited heating across southeast Georgia whereas northeast Florida experienced breaks in the cloud deck allowing for delayed diurnal destabilization. Storms were diurnally initiated across north central Florida in the afternoon due to less cloud cover over that area. Late start for the sea breezes, with them pushing inland late afternoon into evening. Weak westerly flow allowed the Atlantic sea breeze to move inland to the St. Johns River basin. Diurnally driven storms in north central Florida lifted north and interacted with the sea breeze boundary in the evening. Slow-moving storms produced heavy rainfall and caused street flooding in Marion, Alachua and Clay counties. These storms produced about 2.5 to 4 inches of rain. A stronger storm in Marion county damaged a metal roof. Another stronger storm produced penny sized hail in Duval. Lightning struck a teenager in Duval causing injuries.

Area Forecast Discussion National Weather Service Jacksonville FL 156 PM EDT Tue Aug 23 2022 ...New AVIATION... .UPDATE... Issued at 1050 AM EDT Tue Aug 23 2022 Current visible imagery shows a broad band of thick cloud cover extending from a weakening low across ArkLaTex eastward into the Deep South, and across the local area. Deep westerly flow between an upper trough to the north and a ridge axis to the south will continue to advect dense cloud cover across SE GA through most of the day. Cloudiness will hamper heating across SE GA and lower convective chances there this afternoon whereas NE FL will break into sunshine through the course of the morning and promote diurnal destabilization and afternoon tstms. Similar to yesterday, the westerly flow will limit the Atlantic sea breeze from pushing beyond the I-95 corridor, except across north-central FL where westerly flow is weaker and it may push west of the SJR basin. Given anomalous deep moisture sampled from the JAX morning RAOB (PWAT of 2.19"), numerous shower and tstms convection this afternoon along the I-95 corridor as the pinned sea breeze interacts with outflow from early afternoon convection. Scattered airmass convection is likely across inland NE FL with potentially more coverage favoring differential heating zones. Convective threats today will be centered on flood potential, particularly in the the urban and flood-prone locations (urban/creek) interface. For stakeholders along the St Johns River, high tide will be between 4-7pm and heavy rain (2-3") during that period could result in impactful flooding. Otherwise, the threat of damaging winds and/or hail given a "skinny" CAPE profile. With the loss of heating convection will weaken, leaving stratiform showers in its wake, this evening before fading entirely by midnight. Quiet conditions will be favored overnight with moist, westerly flow continuing a stream of dense clouds over the region. High clouds should limit any ground-fog development late tonight. Temperatures in SE GA will be cooler this afternoon due to cloud cover (upper 80s) while areas of filtered sunshine in NE FL will reach the upper 80s/low 90s && .NEAR TERM... (Today and Tonight) Issued at 314 AM EDT Tue Aug 23 2022 A few showers drift east along I-10 early this morning towards Jacksonville as a lobe of shortwave energy migrates overhead in the WSW flow aloft. Humid conditions under scattered to broken multilayer cloud cover should keep fog chances on the low side, though shallow, patchy fog may form over locations that received locally higher rainfall totals from yesterday. After sunrise, weak high pressure west of the area over the FL panhandle and lower AL will help promote light westerly to NW winds ahead of a slow moving cold frontal boundary over northern GA that will move little in the way southward today as upper level troughing over the Mid Atlantic and NE US shifts north and east, dragging shortwave energy east to west near it base along the Carolina coast westward over central GA and along the Gulf coast. The mode for storms will be mainly diurnal and seabreeze driven as in days past as abundant moisture levels with PWATs near 2.25 inches persist over the region. Expect initial diurnally driven scattered showers and isolated storms to lead to numerous to widespread showers and embedded storm coverage, especially over the St Johns river basin lifts north and west towards the pinned Atlantic seabreeze just along and east of I-95. Best timing of storms will be the mid to late afternoon over NE FL areas from Jacksonville south along the St Johns river and points east. Some gusty wet downburst winds 40-50 mph and locally heavy rains from slow moving storms will be the main impacts this afternoon. Activity will end a little after sunset. Temperatures will peak in the upper 80s to near 90 degrees across SE GA with low 90s expected over NE FL and upper 80s at the coast. Tonight, some isolated to scattered showers will drift east off the coast after midnight under partly to mostly cloudy skies. Some shallow fog, patchy in nature may form over areas that receive locally heavy rainfall, but significant fog does not appear likely. Lows on Tuesday night will fall into the lower to mid 70s. && .SHORT TERM... (Wednesday through Thursday Night) Issued at 314 AM EDT Tue Aug 23 2022 Wednesday...Weak low level ridge axis will remain trapped across North FL, while weak frontal boundary still stalled just North of the region across Central GA. The weak flow pattern will allow for the East Coast sea breeze front to push further inland to the US 301 corridor and expect numerous showers and storms to develop over inland areas, but West-Southwest flow aloft will push these storms back towards the I-95 corridor and coastal areas late in the day. Max temps will likely top out around 90 degrees or so in most locations. Heavy rainfall will continue to be the main threat from storms as they move slowly inland along the sea breeze front, then back towards the I-95 corridor later in the day. Thursday...Heavy rainfall set up continues as deep tropical moisture aloft with PWATs over 2 inches interacts with weak frontal boundary that drops south into SE GA, this will allow for an onshore flow to develop and push the East Coast sea breeze well inland during the afternoon/peak heating hours. This low level SE steering flow combined with moist SW flow aloft will help to enhance locally heavy rainfall set up and numerous slow moving storms are expected during the afternoon hours, but overall high coverage of rainfall/clouds will hold Max Temps in the upper 80s/near 90 degrees for most locations. Overall 3 day rainfall totals of 1 to 3 inches are expected with localized 3 to 5 inch amounts likely. && .LONG TERM... (Friday Through Monday) Issued at 314 AM EDT Tue Aug 23 2022 Weak frontal boundary/surface trough remains across the region through the Weekend and into early next week with not much daily change expected. PWATs remain at or above 2 inches and the weak flow pattern and inland moving East Coast sea breeze front will lead to daily rounds of numerous storms with heavy rainfall as the main threat due to slow storm motion. Max temps will remain similar in the upper 80s/near 90 degrees for most locations. The continued threat of daily heavy rainfall will likely lead to some local rises on main stem river basins, and threat of urban flooding issues will continue through the long term period, the diurnal nature of the heavy rainfall and long enough periods between events will likely not necessitate any Flood watches, but will start to become an issue for some areas as ground conditions become more saturated. && .AVIATION... (18Z TAFS) Issued at 154 PM EDT Tue Aug 23 2022 Cloud cover has limited heating and delayed convection along and north of a line from GNV to CRG. South of the line cumulus buildups and convection continues the near term convective threats being GNV and SGJ. Expect outflow and sea breeze to take over and develop convection northward along the I-95 corridor through the afternoon. Convection will fade this evening around 01/02z with linger showers inland near GNV through about 03z/04z. High and mid level clouds will keep ground fog in check tomorrow morning. Though it isn't mentioned explicitly, another sea breeze convective day is anticipated again Wednesday afternoon. && .MARINE... Issued at 1050 AM EDT Tue Aug 23 2022 No significant changes this morning. Expect sea breeze development and numerous afternoon tstms in the nearshore zones. Area waters will remain south of a arcing frontal boundary across northern GA. A fairly weak pressure pattern will remain in control before a weakening front presses into the area from the north Friday and stalling over the waters through the weekend. Fair chances for afternoon storms each day with increasing chances this weekend with the stalled boundary. && .PRELIMINARY POINT TEMPS/POPS...
