On Tornadoes
Tornadoes range in size from F0 to F5 and from a few feet wide to over a mile wide.
During the course of the year, the center of tornado activity moves. In early spring, the center is located in the southeastern US states. During the spring time, it moves west to about North Texas. Then, it moves north into Oklahoma - Kansas area.
Considering that between me and the center of "Tornado Alley" at Wichita Falls, Tx is about 138 miles and that there were only 108 tornadoes registered in the whole state last year, that means that I didn't see a tornado all year. The last time I saw a funnel cloud was about 15 years ago. It is rare for one place to see multiple tornadoes of any strength in one year and destructive ones anywhere close to them. There were a lot more "false positives" given by the local TV weather people than there were tornadoes on the ground.
In short, we have tornadoes about as often as California has felt earthquakes and we get warnings. They don't.
