We got a bit of a late start due to delays with the rental vehicle. Storms were already severe west of the DFW area… but these were never a target/goal for the day anyway. We had planned on using the day as a travel day to end up in Abilene, TX. We stopped south of Seymour to shoot some pictures and video of the supercells that were well east of us when another group of storms got organized to our west and northwest. One storm moving southeastward through Knox County developed supercell characteristics for a period and had nearly continuous lightning. While we didn’t think that a tornado was likely… it did become interesting for a few minutes when the storm interacted with outflow from approaching storms from the southwest. We were happy that a day which was expected to be one of the least interesting in the trip, became the most interesting so far.
