The episode as NWS JAX wrote it up.
High pressure was anchored NE of the region with a SSE steering flow over the local area. A passing upper level disturbance across FL enhanced mid level instability during peak heating which help trigger a few strong to severe storms along the sea breezes and outflow boundaries.
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 Aug 14, 12:26 PM EST, 5 hours 54 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 126 PM EDT SUN AUG 14 2016 .NEAR TERM...This afternoon through Monday... This Afternoon...Deeper convection was slow to evolve across the area early this afternoon with little progression of the east coast sea breeze given abundant mid and high clouds rotating northward on the ENE side of a retrograding upper level low in the central Gulf of Mexico. The filtered sunlight limited heating with many locations across our inland Fl zones still in the low/mid 80s while less cloud cover enabled temperatures to rise into the lower 90s across SE Ga and NE Florida near JAX. A few weak radar returns continued to move the NW across the area associated with the mid level PVA rotating northward round the upper level low. Short range guidance continued to suggest that with additional heating and decreased mid level destabilization deeper convection including some strong to sever storms will ignite across inland NE Florida along and west of the St. Johns River basin. These storms will be capable of producing strong downdrafts given modest dry air just above the surface and steeper mid level lapse rates. High resolution models including the HRRR/HRRRX indicated the potential for a resultant wave of strong/severe storms triggered by convective outflows front the initial cells spawned near the St Johns River basin over the next couple of hours...with outflows pushing generally to the WNW and spawning additional convection across the Suwannee River Valley and inland SE Ga through the late afternoon/early evening. Tonight...Lingering stratiform convection and drizzle is expected across much of the area as deeper/stronger convective cells push off to the NNW through midnight. Gradually increasing onshore flow with a weak coastal trough axis indicated in some of the guidance will bring a chance of coastal showers moving onshore generally along the NE Florida coast early Monday morning before sunrise. Minimum temps will trend a bit warmer due to lingering clouds and increased easterly flow trailing the departing upper level low...and values will range from the upper 70s/near 80 along the Atlantic coast to the low/mid 70s inland. Monday...Deeper easterly flow increasing over the area as stacked ridging strengthens over the western Atlantic with a surface ridge axis across the Carolinas. The stronger east coast sea breeze will move inland by late morning with some coastal showers moving inland toward the I-95 corridor by midday...with convection blossoming westward toward inland SE Ga and the I-75 corridor of NE FL into the afternoon and pushing farther west of the local forecast area during the early evening. With lack of upper level forcing advertised the highest rain chances of 30-40% for coastal NE Fl during the morning and our inland zones during the afternoon with mostly dry conditions across coastal SE Ga due to proximity to subsidence. East winds will become breezy along the coast by midday with max temperatures in the mid/upper 80s...while farther inland temperatures will near the lower 90s toward I-75. A few strong storms capable of gusty winds will be possible Mon afternoon but mid level temperatures will be warming into the -6 to -8 deg C range at 500 mb as the ridge strengthens to our NE...thus reducing severe weather potential. .SHORT TERM /Tuesday through Wednesday Night/... Model guidance maintains surface and upper ridge of high pressure over and north of our area. Will continue to see very warm humid conditions with high temps both days low-mid 90s w of I-95 corridor to around 90 east of I-95. With low-level SE flow should see similar set up for afternoon/early evening showers/t-storms each day with best coverage between hwy 301 and I-75 corridors and less coverage closer to east coast. .LONG TERM...Thursday through Sunday/... Models flatten upper ridge over our area Thu/Fri as shortwave trough move over and offshore from mid-Atlantic states...with little change to upper ridge next weekend. Will maintain chance POPs each day this period with eastward extension of higher POP values toward the east coast. Little change in temperatures seen this period...with high temps in low-mid 90s w of I-95 corridor...around 90 east of I-95. && .AVIATION...MVFR low cigs caused temporary restrictions early this afternoon across NE Fl terminals. This trend will continue as diurnal instability increases and triggers scattered showers and thunderstorms later this afternoon and into this evening. Best chances of thunderstorms today will be near VQQ and GNV based on the latest short range model guidance...but more discrete cells could impact the other terminals. Will monitor radar trends to best time tempo groups for convection. Tonight lingering stratiform and low/mid clouds will gradually erode this evening with lingering mid/high debris clouds overnight. && .MARINE...Prevailing ESE winds will develop tonight and persist through Thu as high pressure axis dominates north of the local waters. Fri winds veer southerly as the ridge axis shifts south of the local waters as a mean layer trough approaches the eastern seaboard. Rip Currents: Low risk today and Monday. .CLIMATE...Jacksonville's 6.95 inches of rainfall since June 1st is currently the 4th driest since records began in 1872. The driest meteorological summer (Jun, Jul, Aug) on record in Jacksonville occurred in 1954 when 8.71 inches of rainfall was recorded. && .PRELIMINARY POINT TEMPS/POPS...
