Overshooting Top Detection Continues to Underestimate Overshooting Tops

The GOES-R Overshooting Top Detection (OTD) product continues to underestimate the number of overshooting tops.   In the top image at 2315 UTC, there are several cold cloud tops around -60C with several severe storms in Ohio, western Pennsylvania, and West Virginia.  The OTD product only detected one overshooting top over Ohio at this time.

The OTD product seems to be underestimating the number of overshooting tops today on May 14.

EDIT: 

I made it clear to the forecasters that even though these storms had cold tops, that does not mean there is an overshooting top. I had them sample the area and it was clear that the OT algorithm was correct in not detecting OT's, as they were just uniformly cold tops, not overshooting the trop. When training forecasters to use this type of product, it is important to make these types of aspects of the products clear.
