Those are the cloud tops in hundreds of feet, i.e. 276 is 27,600 feet.

Those are ECHO tops, not cloud tops — significant difference.

Echo tops are the highest altitude radar return. Cloud tops will be thousands of feet higher.

More important, echo tops are a good indication of convection. My magic number is 300. YMMV.

My magic number is a bit lower - more like 200. This video was of a storm with tops near 230.

As I said, YMMV.

We must also consider storm structure. The reflectivity gradient on the cell in this video should keep us away.

A high gradient cell is no-go regardless of the echo top.

Really good point on echo gradients Dave.
