Excessive Rainfall in the Southern Plains into the Lower Mississippi and Upper Midwest

Heavy thunderstorms will continue to produce areas of excessive rainfall and locally considerable flooding over parts of the southern Plains into the mid-Mississippi River Valley through Saturday. Heavy to excessive rainfall may bring flash and urban flooding, along with isolated riverine flooding across portions of the Upper Midwest, mainly over central Minnesota. Read More >

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.
