It was an isolated storm, but lightning was within the boundary combined with anvil blowoff...
I left the KSC area about 35mins after launch and headed north. Hit a wicked thunderstorm as I got home (Edgewater, about 35mins north of KSC and just south of Daytona Beach by 20mins). Thank god launch wasn't 20mins later or I doubt they'd have made it.
And Rdale... thanks so much for the weather updates. Was checking this site as I sat across the river in Titusville and kept updating all the people around me. It was interesting. About two minutes after you mentioned the shower around Orlando, we saw the STA take off and head toward Orlando to go investigate it.
