Denver is part of Colorado's 'Tornado Alley'6/15/18 There is even a Colorado "Tornado Alley".
When we get surface winds out of the southeast, leading into the Denver metro, those winds will interact with an elevated area of land between Denver and Colorado Springs, known as the Palmer Divide. As a result, favorable tornado conditions can develop quickly in that area and to the north of there. Meteorologists call it the Denver Convergence-Vorticity Zone, or DCVZ. About 60 percent of Colorado tornadoes form in that alley, which includes the east metro.
There is also weather feature called the Denver Cyclone, which often works in conjunction with the DCVZ but can also cause thunderstorms to become tornadic by itself.
The Denver metro sits down in sort of a 'land bowl', surrounded by higher terrain on all sides. Some studies show that south and south-easterly winds can get inside that bowl and start a clockwise or anti-cycloninc circulation. This pulls dry air off the mountains, that collides with the warm moist air coming up from the south. [ link to www.9news.com (secure)]
