The radar loop shows Radar Reflectivity (left) and Storm Relative Velocity (right) in 2 minute increments from 522 PM to 6:11 PM. The red area indicates outbound velocity, and green indicates inbound velocity (circulation, but at 12,000 feet above the surface) At times you can also see circulations in the velocity, which indicate rotating updrafts.
