Another bit of relevant information - the roadblock on the north side of town was in place as the tornado was ongoing to the north, before/as the propane tank/debris had been thrown. You can see the tornado dissipating in the timelapse video as I approach the roadblock. I don't know how long this was in place, but judging from the traffic I encountered, it was at least a few minutes. This meant that the road was likely blocked prior to the tornado impacting the structure, but I cannot say for sure. If it wasn't, they would have had to have it set up within a minute or two of the structure being hit - an unusually fast response time.
