Tornado Touchdown

We did get a confirmed report of a tornado from this cell at 10:11pm CDT in Stanley county, 2 miles West of Hayes from an emergency manager.

Here's a closer up view of the tornado warned storm we broke into programing with... you can see the pink and reds showing the heavy rainfall and hail, this cell used to be one and then it split into two, producing at least two unconfirmed tornadoes. The pink outlines were the tornado warnings on this particular cell... there were 3 warnings out for these storms with 2 different severe thunderstorm warnings (in the red).
This is a look at the storm relative motion or velocity. The green is the motion towards the radar (keep in mind this radar source is Rapid City's radar, so the green area is motion westward) and the red is motion away from the radar, so moving eastward. You can see two pretty bright areas of green right next to red - these areas were wound up around each other which is the rotation that produced the tornadoes near Hayes around 10pm. Round Number 4 is on the way mainly for SE SD on Tuesday... more updates from Cody in the AM.
