It’s been a fairly active summer for thunderstorms, and with them comes the threat of a tornado. The biggest question about thunderstorms and tornadoes is probably why some thunderstorms produce tornadoes and others don’t?
The answer, and likely why I am always hesitant to write about how tornadoes form, is that we just don’t really know. We have a pretty good idea of the conditions necessary for the formation of tornadoes, and from this we can make some good educated guesses, but until we can get detailed measurements of the atmosphere before and during a tornado-producing thunderstorm, the best we can offer is just that — an educated guess.
