56 Years of Tornado Tracks

The United States of America has such a unique geography, that we have the majority of tornadoes in the world.  Three key items in for the US are the Rocky Mountains location and size, plus the warm moist air from the Gulf of Mexico, and the cold dry air from Canada.  As low pressure systems pas over the mountains and mix the moist warm and cold dry air, instability increases.  If the situation is perfect, severe storms form and tornadoes can follow.  Above is a picture or tornado track from the last 56 years.  The bright tracks are the strongest tornadoes, and usually some of the longest.  Find where you live and see how many tornadoes were in your area.
