Interesting wording on that:

Quote: TORNADIC DAMAGE CAME VERY CLOSE TO
THE GROUND IN SEVERAL LOCATIONS.

If the only evidence for the tornado is the damage, and the damage can't be confirmed all the way to the ground, was this really a tornado? Or does tree damage automatically mean that the tornado is considered to have technically been "on the ground"? Personally I would say if it reaches the trees, it's a tornado, but this just got me wondering exactly what kind of damage you would need to prove that a vortex has actually reached "all the way to the ground". What exactly constitutes the ground, in these kinds of situations? If the only damage from an event is, say, a tall building that was unroofed, is that alone enough to get the event classified as a tornado? Just curious.

Remember the definition for a true tornado. If there is a debris cloud of some sort and damage indicated especially with trees in a spiral like fashion then it was a tornado. In this case it sounds like it was a touch down as for trees were damaged. However there is no evidence of a spiral pattern in any way so indeed it is hard to tell for sure..

Remarks related to the above:

"When the visible funnel does not reach the surface, silly reports of a "funnel cloud accompanied by wind damage" can occur, or such absurdities are reported as "The funnel only reached treetop level" or whatever. We probably will find it difficult ever to convince the public as a whole that a tornado is wind and not the funnel cloud. Hopefully, no self-respecting meteorologist would do anything to perpetuate such misconceptions......."
