Where is Tornado Alley and why storm chase there?


Although tornadoes can and do occur in many parts of the world and at many different times of the year, the Mid-western United States is a particularly prolific tornado producing region, especially during the springtime and summer months, and in a region known as Tornado Alley.  Tornado Alley is generally considered to encompass the Mid-western states of Texas, Oklahoma, Kansas, Nebraska, eastern Colorado, eastern Wyoming, southeastern Montana, North and South Dakota, southwestern Minnesota, Iowa, Missouri, Arkansas, Louisiana, Tennessee, Illinois, Kentucky, Indiana and Ohio.   Geographically, the Mid-western states are perfectly situated to receive warm, moist air out of the Gulf of Mexico, strong winds from the upper mid-latitude troposphere and warm mid-level air out of the high terrain to the west, near the Rocky Mountains.  When these factors combine they create tremendous potential for the release of explosive atmospheric energy, thereby promoting the possibility and likelihood, of thunderstorms and supercell rotating thunderstorms; ideal conditions for storm chasing.

As you can see, the area encompassing the Tornado Alley region is vast.  Although Twister Tours, USA is dedicated in getting our guests up close and personal to supercell thunderstorms and tornadoes in many Tornado Alley areas, we prefer to storm chase in the areas of Texas, Oklahoma and Kansas.  We strongly feel that these are some of the very best states for the successful interception of supercell thunderstorms and tornadoes. Here’s why... these areas afford our group with the best tornado viewing possibilities due to their lack of high vegetation, namely, trees.  Other reasons for these areas being the best for chasing, is that they have better road networks.  Road networks provide us with options that allow us to skirt around storm systems.  This means that the developing or exploding supercell thunderstorm can be viewed from many different angles; each providing a completely different perspective of the same storm.  Good road networks are also important should it become necessary to escape the eminent danger of severe hail, dangerous lightning or the path of a large, developing tornado.  Again, these areas are preferred although we will go wherever is necessary to view the best supercell storms and to increase our possibilities of tornado interception.
