I have enjoyed reading more about this event. It was brought back to my mind this evening by, of all things, noticing that my little toddler's bath water was going down the drain anticyclonically. I grew up in Minden and was 3 at the time of the event, so I have no personal recollection beyond the stories of my brother who traveled with my dad to help out to aid the recovery and those of my cousins who lived on the north edge of Hastings and said it was the scariest storm event they ever witnessed even though it didn't affect them directly.
When I was in college, I did a bit of research work into the meteorological setups of the NW-flow supercells in central Nebraska. During that research, I visited the NWS office in Hastings to pick their brains and their archives over the event. I was lucky enough to get a copy of the weather bureau radio transcript from that night. It is riveting to read.
