The OT detector caught one spot amidst a long line of moderate rain and thunderstorm activity moving through Tennessee on Wednesday afternoon.

See? There it is! Taking a look at the IR imagery, this overshooting top sticks out like a sore thumb.

Sampling showed that this OT was about 15 degrees colder than the surrounding cloud. In this situation, the signature was very easy to spot on both products. However, this cell did not induce a warning of any kind. Radar imagery did show that this OT matched up with the area of heaviest rainfall in the storm line, maxing out around 55-60 dBZ.
