Hardest hit states include; Illinois, Alabama, Kentucky, Tennessee and Indiana. Schools, homes and businesses were demolished by super-cell thunderstorms this afternoon and over 10 states had counties under tornado warnings at one point today.

A trigger such as a cold front or an active jet stream can produce large changes in wind direction and wind speed with height and this helps a thunderstorm rotate which ultimately can spawn a tornado with destructive consequences.

Lets hope that this early season outbreak is not a sign of things to come.

2011 was one of the worst tornado seasons ever with over 550 fatalties which is the second highest in a US history only behind the year 1925.
