Over the last few days we here in Colorado have been reminded in a hurry that it's tornado season with watches warnings, and even touch downs near us. Although we aren't in the Kansas, Oklahoma "Tornado Alley" area, Colorado is still very prone to produce a twister or two this time of year. 

Although the reason I am writing this article is because of the recent storms in the area, and also because it's the sixth anniversary of the worst tornado in Colorado history in Windsor, May is NOT the worst month for tornadoes in Colorado. That would be June. The sixth month has seen over 700 twisters since 1950. The next closest month is July with over 400, and May comes in third with about an equal amount as July. The season isn't limited to those three months though. August, April, September, October, March, and February have seen at least a couple tornadoes.
