High-based Funnel over Southwest OK (June 2003)

High-based Funnel

Funnel clouds may develop well above the general cloud base of a thunderstorm, sometimes from the side of a cloud tower, sometimes far up into its middle levels. That is the case here, at middle right, where a well-formed funnel dangles from the side of a ragged convective tower. These "high-based funnels" usually are weak and do not touch down or cause damage on the ground; but every once in awhile, one will. This storm was a splitting supercell, the funnel developing from a small updraft in between two others. It did not become a tornado.
