Blackford County

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

In the first picture below, the storm is entering southern Blackford County.  It then proceeded northeast across the county, without ever displaying any apparent reflectivity signatures that would suggest a tornado.

Velocity
The reds depict air moving away from the radar, the greens depict air moving 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.

In the first three pictures, there is some disorganized circulation moving over southwest and central Blackford County.  In the last picture the circulation begins to get a bit better organized and slightly stronger.
