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 Tallahassee, FL wrote its last area forecast discussion before the first event at Jul 12, 2:43 PM EST, 3 hours 32 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL ISSUED BY NATIONAL WEATHER SERVICE MOBILE AL 343 PM EDT Thu Jul 12 2012 .SHORT TERM...[Tonight through Sunday night]. The upper trof oriented along the lower Mississippi river valley retrogrades somewhat into the southeastern Plains through Saturday as upper ridging builds into the southeast states. Abundant gulf moisture in place over the area with precipitable water values near 2-2.2 inches will see a modest decrease to 1.7 to 2 inches by Saturday due to correspondingly modest subsidence with the upper ridging. A weak stationary front currently extending from eastern Texas northeastward to eastern Tennessee retreats westward and weakens through Saturday as surface ridging over the east central states builds into the southeast states along with the upper ridging. For Friday...a weak inverted trof...an eddy in the easterlies...will move across the northern Gulf and combine with the sea breeze to produce enhanced convective development in the deeply tropical airmass over the region. Will have pops increasing to likely over the western portion of the area with chance pops elsewhere...then pops decrease overnight to low end chance/slight chance. The inverted trof works further inland mainly into Louisiana and Mississippi through Saturday with the forecast area left with the sea breeze as the primary forcing mechanism. Will have good chance pops over the western portion of the area...where deep layer moisture is highest...tapering to low end chance pops over the eastern portion. A vigorous shortwave system meanwhile advances across the northern plains and into the Great Lakes region on Sunday...and phases with the southeastern Plains upper trof. The combined upper trof then advances to the lower Mississippi river valley again Sunday into Sunday night with ridging over the southeast states retreating into the western Atlantic. Precipitable water values will be slightly below normal...near 1.5 inches...due to modest subsidence from the retreating upper ridge. The surface ridging over the area weakens meanwhile and shifts southward to be oriented along the coast maintaining a light southerly flow over the forecast area. The sea breeze remains the primary forcing mechanism for the most of the area again on Sunday and will continue with chance pops. The potential for severe storm development continues to be low through the period though convection that does develop will have the potential for locally heavy rainfall thanks to the deep tropical airmass over the area along with gusty winds and frequent lightning. Temperatures will be near seasonable levels on Friday then slightly above seasonable levels Saturday and Sunday. /29 && .LONG TERM...[Monday through Thursday]. The phasing of the weak upper trof over the lower Mississippi river valley and the northeast states shortwave trof breaks down on Monday with the northern system exiting into the Atlantic. The weak upper trof retreats westward Tuesday into Wednesday into the Southern Plains with modest upper level ridging building into the southeast states. A longwave trof begins to amplify over the northeast states on Wednesday...and builds into the southeast states on Thursday. A surface ridge oriented along the northeastern Gulf coast moves into the northern Gulf by Thursday as a trailing cold front...associated with a Canadian system moving off into the Atlantic...moves gradually southward into the Gulf coastal states. At this time the front looks to remain north of the forecast area but convective development may be enhanced over the northern portion of the area. Otherwise...a light southerly flow will continue over the area with the sea breeze as the primary mechanism for convective initiation. Deep layer moisture improves over the area on Monday to near 1.9 inches and remains close to this through Thursday. Temperatures will generally be near seasonable values through the period. /29 && .AVIATION... [18Z taf issuance]...scattered convection is ongoing across the Florida panhandle and will continue to progress inland through the early evening. Outside of the showers and stores...vfr conditions will prevail with light southerly to southeasterly winds. If the East coast sea breeze progresses westward fast enough...the easternmost taf sites could experience another rough of storms early this evening. Fog and mvfr conditions will be possible and the northern tier of taf sites early Friday between 10 and 14 UTC. 07/MAB. && .MARINE... Surface high pressure over the western Atlantic noses westward into the southeastern U.S. resulting in a light onshore flow and small sea states through the period. Winds...waves and seas locally higher in and near storms. Will keep the possibility of waterspouts due to the very moist environment and light winds. /10 && .FIRE WEATHER... A moist southeasterly flow will continue over the area through the weekend. Afternoon relative humidities will remain well above critical levels with scattered to occasionally numerous showers and thunderstorms. /29 && .PRELIMINARY POINT TEMPS/POPS...
