UGGHHH, sorry. My oldest son is in ATL tonight, flying between there and DCA tomorrow mid afternoon. Begged him to change his flight because of my suspicions for tomorrow, based on your report this evening. Mr. "I CAN HANDLE IT, DAD" was having no part of it, though.
Sun AM Update: I talked my son into changing his flight to Mon AM, he's seen some of the radar and storm coverage from FL last night and this morning, and I shared this post with him. Thx for the report, @bigtenfan...you helped me put his travel decision over the edge.
