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 12, 7:49 PM EST, 1 minute earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 849 PM EDT Mon Jul 12 2021 .UPDATE... Heavy showers/storms continued across interior southeast Georgia early this evening, with only a few showers/storms across the rest of the area. This activity will wind down before midnight, with quiet conditions overnight. Overnight lows will be in the low to mid 70s. && .PREV DISCUSSION [745 PM EDT]... .NEAR TERM [Tonight through Tuesday]...Upper low along the east central Fl coast will continue to drift north reaching the Carolinas on Tuesday. Cold temperatures aloft have produced a few strong storms this afternoon but dry air aloft has limited the areal coverage. Convection should end this evening over land but may continue over the coastal waters as the low traverses the area. An east to southeast steering flow will continue on Tuesday as the subtropical ridge axis remains to the north. This will result in most of the afternoon storms occurring inland. .SHORT TERM [Tuesday night through Thursday night]...An increase in moisture associated with an inverted trough will push into the area on Wednesday increasing our pops. Locally heavy rainfall will be possible on Wednesday as the cell motion decreases. Drier air aloft will then begin to advect in on Thursday which will bring a decreasing trend in rain chances. Temperatures will continue near normal. .LONG TERM [Friday Through Monday]...Bermuda high pressure ridge will shift south over the area Friday and Saturday and then south of the area early next week as an upper trough moves from the Great Lakes to the east coast. Subsidence and drying will bring a decrease in diurnal convection Friday and Saturday. Moisture will then increase Sunday and Monday with pops returning to near average levels. Temperatures will near average through the period. .AVIATION... [Through 00Z Wednesday] A couple showers could get near KGNV and KSGJ early this evening. Otherwise, dry conditions are forecast to prevail overnight. Fog is possible at KVQQ overnight. Southeast winds 5-10 knots will become light overnight and then southeast 10-15 knots on Tuesday. Widely scattered showers and storms will move inland from the Atlantic waters on Tuesday, and along the east coast sea breeze Tuesday afternoon. A wave will move up from the south on Tuesday, leading to showers/storms in the afternoon, especially towards KGNV. .MARINE...Surface high pressure ridge over the region today will shift north of the area tonight producing east to southeast winds through Saturday. Wind speeds will be mostly 10-15 knots with seas 2-4 ft. Showers and storms can be expected over the waters tonight as an upper low moves over the area. An inverted trough will move across the area on Wednesday which will bring another increase in shower activity. Rip Currents: Moderate risk to continue the next few days due to the persistent onshore flow and swells. .HYDROLOGY...Minor to moderate flooding will continue on the Santa Fe and St. Mary's Rivers through this week. && .PRELIMINARY POINT TEMPS/POPS...
