NOTE 1: A single storm may occupy several warning polygons during its lifetime. Each polygon is an entry in the table. If more than one tornado touches down in a warning polygon it is counted as one verified warning. A single tornado can lift and touch down again in the same polygon. Multiple tornadoes in a single polygon = 1 verification. Decatur Co. IN warnings are included because they are part of the FOX19 NOW viewing area but not part of the @nwsiln area of responsibiity. They are not part of the verification, false alarm and missed rates statistics calculated for the table.
NOTE 2: There are a number of reasons a tornado warning can be cancelled they include: a warning that should never have been issued, the storm weakens or rotation disappears, the storm moves out of the warning polygon, in which case the warning may be extended into a new polygon. Often when the NWS is very busy or the storm weakens a short time before the expiration, the warnings are allowed to expire after notifyng the public without additional comment.

John A. Roebling Suspension Bridge,
completed just after the Civil War, it was the first permanent structure to span the Ohio River.
Roebling used multi-strand cables for the first time on so long a structure marking a great
leap forward in bridge engineering. This was the prototype for the Brooklyn Bridge and my favorite Cincinnati landmark.
