Tornado Alley
It has also been asserted that there are numerous Tornado Alleys. In addition to the Texas/Oklahoma/Kansas core, such areas include the Upper Midwest, the lower Ohio Valley, the Tennessee Valley and the lower Mississippi valley. Some studies suggest that there are also smaller tornado alleys located across the United States.
Tornado outbreak of mid-October 2007
The first severe thunderstorms developed during the early morning of October 17 across much of northern and eastern Texas and parts of Oklahoma and Kansas with only one reported tornado in east Texas. Several severe thunderstorms then later developed across eastern Oklahoma, Arkansas, Louisiana, western Mississippi, eastern Kansas, Missouri and parts of Nebraska, Iowa, Kentucky, Illinois and Tennessee. Twelve additional tornadoes were reported in Missouri and Louisiana during the late afternoon and early evening with damage reported in Lawrence and Greene counties in Missouri. One of the tornadoes located near Verona destroyed several barns and homes but did not cause any injuries and was later confirmed as an EF2. The storms persisted throughout the night and an additional tornado killed 2 people inside a mobile home in Greene County, Missouri near Paris.
