The weather for Sunday May 13 2012 was not unexpected. However, being the weekend, there was not much coverage. You know how local TV stations are on weekends, nothing until the evening news, unless there is a weather warning of some type. For a full rundown on the lack of weather news that day, see here – Well, that was interesting..storms on May 13 2012..Only Human
On with the Tornado in Lee County Alabama report …
This was not a classic tornado, nor was it strong and long lived. It was what many in weather refer to as a ‘quick spin up’. Most tornadoes of this type occur due to an increasing unstable atmosphere in or around a strong thunderstorm. This is why you should take a ‘severe thunderstorm warning’ just as serious as a Tornado Warning, as many times a tornado can spin up. Another reason is because severe thunderstorms are capable of causing damage equal to small tornadoes such as the one here in Lee county due to straight line winds.
The funny thing about this Tornado, the Tornadic winds estimated in the official assessment below barely met criteria for a Severe Thunderstorm. That being winds of at least 58 mph (50 knots).
