There's a modification application pending on the tower which WKBO is located, that very well could be related. I'm not from the area, but my understanding is that the station is co-located on an American Tower structure which also supports other communications antennas. That'd lead me to believe the station is skirted on the tower. It sounds like there may have been a grounding issue, or larger issues with the tower itself.
You'd be surprised how much damage a lightning hit can do to a well grounded and protected station. I've seen lightning hit a steel structure that was well grounded, but the hit caused an electromagnetic pulse which took out a lot of gear. Lightning's tricky...
