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 Jun 14, 2:22 PM EST, 2 hours 2 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 322 PM EDT Wed Jun 14 2017 .NEAR TERM (Rest of today-Thursday)... Rest of today...expecting scattered to numerous showers and storms focused mainly over northeast FL with more scattered or even isolated storms over SE GA. Main threats will be locally heavy rainfall and frequent to excessive lightning. Vigorous updrafts and precip loading will allow for gusty winds that may exceed 40-45 mph in the strongest storms that develop from boundary interactions. Tonight...Scattered showers/stratiform rains and thunderstorms expected in the evening with sea breezes and left over outflow boundaries triggering convection. This convection will then fade/dissipate after midnight. Like prior nights...low stratus and patchy dense fog will probably form...with locations where this occurs highly uncertain due to model disagreement and lack of a focus other than local areas of heavy rainfall. Fairly typical low temps for June in the lower 70s. Thursday...mean layer ridge will edge a bit southeast to south during the day as a mid to upper level shortwave trough drops slowly southeastward over SE GA and the FL big bend. Moisture levels remain about the same as today with PWATS of about 1.8 to 2.1 inches. Modified sounding yields SBCAPE of about 3000 J/kg, which may be a little conservative. Slightly drier air in the mid levels may support a higher risk of localized strong downdrafts/gusty winds. Based on latest model support...will continue with sct to numerous showers and storms...mainly focused over NE FL. Initial development around 10am-1pm appears to be over the east and southeast zones ahead of the upper trough and the east coast sea breeze boundary. Convection should focus inland during the late aftn. Unfortunately with more insolation we are anticipating high temps to be pushing higher than the past few days with lower 90s more common...slightly lower at the coast. Max heat indices of about 100 are expected. .SHORT TERM /Thursday night-Friday night/... A baggy upper level short-wave trof will move into the SE US Thursday night and drift then linger over the region Friday. At the surface, the ridge axis will drift south into central Florida Friday. Thursday night, convection will wane considerably with the loss of daytime heating with isold showers and thunderstorms west of 301 and isold to scattered east of highway 301. lows Thursday night with lows mainly in the 70 to 75 degree range. On Friday, plenty of tropical moisture and minimal suppression should allow convection to fire up once again. Precipitable water values will be between 1.90 and 2". Convection may get an early start across north central Florida Friday, focusing initially along Flagler and southern St. Johns county late morning then pushing north and west across the souther tier interior counties during the afternoon. Across SE GA, a weakly cyclonic flow regime will be in place with SW flow advecting a couple weak disturbances through with isold to scattered convection getting going first across the interior western areas late morning then drifting eastward during the afternoon with coverage being scattered to numerous. The convection across NE FL will be mainly diurnally driven, but may see scattered convection through mid to late evening over the NE FL First Coast counties with blow-back from weak westerly steering flow. Primary threats Friday will be frequent CG lightning, wind gusts 30 to 40 mph, and locally heavy rain with weak steering flow. High temps Friday will be mostly in the upper 80s. Lows Friday night mainly in the 70 to 75 degree range. .LONG TERM.../Saturday-Tuesday/... Not a lot of change this weekend as long range models continue to indicate the deep layer sub-tropical ridge will be near or just south of the while a weak trough persists across the Fl panhandle into Ga. This will continue to produce a moist and unstable southerly flow which will lead to mainly diurnal showers and storms. Temps will average slightly above normal this weekend. Monday and Tuesday...A strong shortwave will eject out of the Great Lakes into Ontario/Quebec Monday. This will push a cold front into northern Georgia and northern Alabama Monday and lingering there through Tuesday. An anticyclonic flow around the Bermuda High will continue to push ample tropical moisture into the region. This will continue to produce a moist and unstable S-SE flow through Tuesday which will lead to mainly scattered diurnal showers and storms east of I-95...with showers and storms more numerous west of I-95. Still have ECMWF/GFS agreement on a tropical wave developing off the Yucatan next week and moving into the west-central or western Gulf. Temps will average slightly above normal. && .AVIATION... For most part VFR CIGS expected outside scattered afternoon/evening storms with MVFR to IFR VSBY and CIGS possible in and near storms. By late evening and around midnight...will keep VFR but some lower conditions possible in fog and stratus between 08z-14z mainly for GNV and VQQ but confidence is low at this time. Another round of scattered showers and storms Thursday. && .MARINE...Sfc ridge will remain east and southeast of the area waters maintaining south to southwest flow through Friday except for east coast sea breeze each day. Slightly stronger southerly flow Thu night and Fri night as sfc trough develops inland over SE GA...increasing local pressure gradient. During the weekend, sfc ridge lifts a little northward with speeds still aob 15 kt. Winds may begin to turn a little more south-southeasterly Sunday through early next week as tropical wave moves through the eastern Gulf/Yucatan. Rip Currents: Low to moderate risk through Thursday due to weak easterly swells. && .PRELIMINARY POINT TEMPS/POPS...
