June is historically Denver’s severe weather month and severe thunderstorms, tornadoes and hail are notorious visitors to Denver and across eastern Colorado during the month.

In fact, over 40 percent of the tornadoes that occur in Colorado are observed in June and these are typically the most destructive of the year.  Thornton of course knows this fact well as this year we celebrate the 30th anniversary of the infamous Thornton tornado of June 3, 1981.

Severe thunderstorms have also caused major property damage across the Front Range during the month.  Just last year hail the size of golf balls caused damage across parts of central and northeastern Thornton.
