Severe Weather Outbreak of August 8, 2006

Showers and thunderstorms began during mid afternoon on Tuesday mainly in the sea breeze zone in the Florida Panhandle and Big Bend. Two additional areas of convective activity began at approximately the same time, one in central Georgia, and the other in southeast Georgia.

Intense thunderstorms began in Florida around 1 to 1:30 pm CDT in the Panama City area. These storms continued to develop and spread eastward across much of, if not all of the Florida Panhandle and Big Bend. Additionally, strong and severe thunderstorms moved across the south central Georgia and Interstate-75 corridor around 5 to 5:30 pm EDT. Several thunderstorm outflow boundaries collided in southern Leon and northern Wakulla Counties producing a series of strong and severe thunderstorms in that area.

The central Georgia storms developed into nearly a solid east-west squall line around 6 pm EDT extending from Fitzgerald in the east through Ashburn and Leesburg westward to Georgetown, and even extended into southeast Alabama near Clayton and Eufaula. Figure 1 shows the line about an hour later. Convective outflow boundaries moving northward from the Florida storms intersected the east-west squall line over southwest Georgia and produced numerous severe weather reports including several tornado reports, power outages, property damage, and countless trees being reported down.

However, the most significant damage was reported in southeast Alabama, particularly in the Napier Field, Midland City, and Pinckard area where estimated 70-mph thunderstorm wind gusts occurred. Base velocity data from just after the thunderstorm gust front pushed through the heavily damaged area is shown in Figure 4. Damage from the area is shown in Figures 5 and 6.
