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 21, 2:33 PM EST, 3 hours 57 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 333 PM EDT Sun Jul 21 2019 .NEAR TERM /Today and Tonight/... Potential for strong thunderstorm formation this afternoon as a rotating shortwave makes its way northward, already producing storms with hail and winds capable of knocking down trees along the sea breeze fronts. This area of instability is expected to continue proceeding to the north for areas west of and near the I-75 corridor, however with the dry air aloft storms capable of producing hail, gusty winds, and locally heavy rainfall can not be ruled out for other areas. Storms are also forming along the east coast sea breeze and will continue to develop and press inland, with the sea breezes meeting up near and west of Hwy 301 later this afternoon. Storm activity is expected to disperse later tonight, after sunset. Overnight low temperatures are expected to be in the low 70s for inland areas and in the mid 70s for coastal locations. .SHORT TERM /Monday and Tuesday/... Prevailing flow will shift about to out of the southwest as the high pressure ridging weakens over the forecast area and drifts southward. Reduced PWAT values ranging between 1.5 to 2 inches are forecasted for Monday which could lead to scattered storms forming in the late afternoon to early evening hours, with the area of heaviest convection likely occuring near the I-75 corridor and in the southernmost counties of the forecast area. Conditions on Tuesday will become very unstable as a strong front presses into Georgia from out of the northwest, thus bringing significantly more moist air with numerous thunderstorms and showers expected to form all throughout the region with the heaviest storms forming in the afternoon and evening before dispersing in the early AM hours. High temperatures for the beginning of the week are expected to be reach into the mid and lower 90s for inland areas where cloud cover and storm formation is minimal, with temps along the coastlines being in the low 90s. Heat index values cam range as high as as 99-105 degrees. Overnight low temperatures will be in the low to mid 70s for inland areas and in the upper 70s for coastal locations. .LONG TERM /Wednesday through Saturday/... Models show that the frontal boundary is expected to stall over Georgia through Thursday, which will result in significant thunderstorm developments for Wednesday and Thursday. The boundary will begin to retract on Friday, moving off towards the north, and high pressure ridging from out of the east will extend over the region Saturday bringing with it drier conditions and reduced levels of convection. Max temperatures are expected to drop slightly in the coming week as a result of the increased convection and cloud cover, with max temps dropping to the lower 90s and upper 80s by midweek and remaining in the low 90s into the weekend. Heat index values are expected to drop into the 90s during the period of heaviest storm development, but then return to 100 degrees and higher on Saturday. Overnight low temperatures are anticipated to be in the lower 70s for inland areas and in the upper 70s along the coastline. && .AVIATION... Showers and storms were forming along the sea breeze boundaries early this afternoon, and these showers and storms will spread inland through the afternoon hours. Storms will become more numerous across the interior towards KGNV and KVQQ, and have TEMPO groups for these TAF sites. Light winds will become southeasterly around 10 knots as the east coast sea breeze moves inland. Storms will diminish this evening with loss of daytime heating, with light winds and VFR conditions prevailing overnight. && .MARINE... Surface high pressure will extend across the Florida peninsula through Monday with winds increasing to about 15-20 knots Monday night through early Tuesday morning in association with a low pressure trough develops in the NW. A stronger front will move southward toward the local waters late Tuesday and weaken near the local waters Wednesday and Thursday.
