Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

What happened

The episode as NWS JAX wrote it up.

An upper level ridge was northwest of the area while Tropical Depression #3 was nearing south Florida. Between the two features a swath of dry air was positioned over north Florida and southeast Georgia. During the afternoon, a mid level lobe of positive vorticity moved over southeast Georgia from the northeast around the upper ridge. This sparked scattered showers and storms near the Altamaha River basin that tracked southward during the afternoon on the fringe of the dry air swatch. One storm became severe over Atkinson county. The cell produced a large outflow boundary that propagated south across Clinch, Lanier and Echols county's while weakening.

What forecasters said that day

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 22, 1:35 PM EST, 2 hours 12 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
235 PM EDT THU JUL 22 2010

...INCREASING RAIN CHANCES LATE FRI THROUGH SAT...

.SHORT TERM...TSRA WERE STARTING TO FIRE NEAR THE ALTAMAHA RIVER
BASIN THIS HOUR WHERE THE RUC80 INDICATED PVA ROTATING WEST ON THE
EAST SIDE OF THE 1000-500 MB HIGH CENTERED OVER AL. EXPECT THIS
ACTIVITY WILL CONTINUE THROUGH LATE THIS AFTN/EVENING WHILE MOVING
WSW. THE MAIN CONVECTIVE CONCERN WILL BE GUSTY WINDS GIVEN SUCH
STEEP MID LEVEL LAPSE RATES AND DRY AIR INFILTRATING ALOFT. AFTER
SUNSET CONVECTION WILL DISSIPATE AND SKIES WILL CLEAR. COULD SEE
SOME PATCHY FOR AFTER MIDNIGHT AS LOWS FALL INTO THE LOW/MID 70S
INLAND...UPPER 70S COAST.

MOISTURE ON THE NORTHERN PERIPHERY OF T.D. 3 WILL APPROACH OUR SE
ZONES FRI AFTN WITH A TRAILING MOISTURE PLUME AND MID LEVEL ENERGY
CONTINUING OVER THE CWA THROUGH SAT WITH PWATS AOA 2.2 INCHES. WITH
A PREVAILING ELY FLOW REGIME...POPS WILL FIRST IMPACT OUR EASTERN
ZONES LATE FRI WITH SCT/ISOLD CONVECTION SPREADING N AND INLAND FRI
NIGHT THROUGH EARLY SAT. THE FOCUS FOR HIGH CHANCE POPS WILL SHIFT
FARTHER INLAND SAT AFTN AS THE TROUGH AXIS SHIFTS WEST OF THE AREA
AND DRIER AIR BEGINS TO FILTER OVER THE CWA FROM THE EAST ONCE
AGAIN. SUN DRIER AIR WILL CONTINUE OVER OUR EASTERN ZONES WHILE
BETTER MOISTURE AND SHALLOW SEA BREEZE INDUCED FORCING IS EXPECT TO
OCCUR NEAR THE I-75 CORRIDOR DURING THE AFTN/EVENING.

TEMPS WILL CONTINUE TO BE WARM IN THE LOW/MID 90S WITH HUMID
CONDITIONS DUE TO INCREASING MOISTURE VALUES. HEAT INDICES WILL
NEAR 105 DEG EACH AFTN THROUGH SUN.

.LONG TERM...MON THROUGH THU...PWATS ARE EXPECTED TO RANGE BETWEEN
1.5 TO 2 INCHES THROUGH WED WITH A MEAN LAYER ELY FLOW FOCUSING THE
AFTN/EVENING SEA BREEZE MERGER ACROSS OUR WESTERN ZONES. THE CURRENT
FORECAST ADVERTISES POPS OF AROUND 30-40% WITH A NE-SW
GRADIENT...AND SEE NO REASON TO CHANGE ATTM. THE UPPER HIGH IS
EXPECTED TO RETROGRADE FROM S GA TOWARD MS/AL LATE WED INTO THU.
THIS WILL ALLOW A SWATH OF HIGHER MOISTURE WITH PWATS OVER 2 INCHES
TO SHIFT SOUTHWARD ON THE E SIDE OF THE RIDGE AND OVER OUR CWA WITH
POPS INCREASING TO NEAR CLIMO VALUES OF 40% ACROSS THE ENTIRE CWA.
MAX TEMPS WILL BE IN THE LOWER 90S WITH MINS IN THE MID 70S.

&&

.AVIATION...PREVAILING VFR EXPECTED. ANY SHRA DEVELOPING THIS AFTN
WILL REMAIN N OR NW OF TERMINALS. NOT AS MUCH DENSE SHALLOW
GROUND FOG EXPECTED TONIGHT AND WILL GO WITH A FEW HOURS OF MVFR
VIS BUT NO CIGS AT VQQ AND GNV BETWEEN 08Z AND 11Z.

&&

.MARINE...WINDS AND SEAS WILL BEGIN TO INCREASE TONIGHT FOR THE
SOUTHERN LEGS AS THE TROPICAL DEPRESSION MOVES MOVES WEST AND
TIGHTENS THE GRADIENT OVER THE AREA. SMALL CRAFT ADVISORY
CONDITIONS ARE POSSIBLE FOR THE OFFSHORE WATERS FRI NIGHT INTO
EARLY SAT ALONG WITH SCATTERED SHOWERS AND STORMS. THE LONG FETCH
OF ONSHORE WINDS AND SWELLS WILL RESULT IN AN ELEVATED RISK OF
CURRENTS.
