What is that odd anomaly appearing on tri-state radar?


If you’re a weather junkie, chances are you spend a lot of time watching the radar during severe weather.

But if you happened to take a glance on Monday, you were probably scratching your head trying to figure out just what that severe storm-looking-return was all about.

And you weren’t alone.

After tracking this anomaly for hours, even the National Weather Service had a tough time trying to figure out why a radar return resembling a severe storm was moving across the tri-state, and elongating as it moved.

There were clearly no storms in the area.

So then, what was it?

Officials with the weather service say they believe mysterious return is – “military chaff.”

Chaff has been around about as long as radar itself.

Invented by the military, chaff can be made up of a number of particles.

And when released from planes, it can fool ground-based radar by producing false returns.

The weather service tells our media partner, The Courier & Press, the blip originated in Richland County, Illinois, which is located near several military installations.

Eyewitness News Chief Meteorologist Wayne Hart has informed us that a pilot was told by the Evansville Air Traffic Control tower, that a military C-130, did in fact, release chaff on Monday, northwest of Evansville.
