Reflectivity
The oranges and reds signify heavy rainfall and possible hail.

These radar reflectivity pictures show the storm moving out of Van Wert County and into southeast Paulding County. Note that the storm never really displays a classic "hook echo", despite producing a tornado of F3 strength in this area.

Velocity
The reds depict air moving away from the radar (outbound), the greens depict air moving inbound toward the radar (in these pictures, the radar is to the upper left, out of the picture). Reds and greens right next to each other suggest circulation, since there are air currents flowing in opposite directions in close proximity to each other.

"Vr" is rotational velocity, which is simply the average of the maximum outbound wind speeds and maximum inbound wind speeds. It can be used to give an idea of the strength of the circulation. Note that the circulation peaks in intensity near Roselms, which is where F3 damage was found.
