There is a volatile pattern setting up for fast moving supercells in South
Dakota, and perhaps northwest Nebraska. We are on the way....form Goodland.
Hodographs favor fast motions, but also a few tornadoes....with some strong and violent.There is a volatile pattern setting up for fast moving supercells in South

....and we should have stuck with our target. But storms erupting ahead of the cold front in western Nebraska were supercells and were producing tornadoes early on. So we attempted to get along that line and wait for the rapidly moving storms to train up the boundary to us.
One in particular near Alliance (see radar) had a history of producing TVS (tornado vortex signatures) and was intermittently tornado warned by the NWS. However, by the time we got in position, the whole area erupted into a rapidly moving squall line. Outflows from neighboring storms crashed through our storm and it became non-supercellular and absorbed into the line.
If we had left at 7AM we may have made it to our target in time to see South Dakota tornadoes at 1PM. That's about 6 hours earlier than tornadoes normally form. But them's the breaks...
