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.
The episode as NWS FFC wrote it up.
A hot, humid air mass continued across the region. A large subtropical upper ridge remained anchored over the southern Plains and extended eastward into Alabama. Georgia was just outside the immediate influence of this upper ridge, with northern flow aloft. A broad upper trough was aligned along the Northeast and Mid-Atlantic coasts. The combination of weak disturbances rotating around the Northeast U.S. upper low and the hot, humid surface air mass allowed for typical diurnal convection across north and central Georgia. Storms were quite isolated and generally below severe limits, but a couple did become severe producing damaging downburst winds and quarter-sized hail.
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 Atlanta, GA wrote its last area forecast discussion before the first event at Jul 1, 2:30 PM EST, 1 hour 15 minutes earlier.
