The service issued tornado warnings for four counties immediately south and east of Denver, but not for the city itself.
"Numerous trained weather spotters reported several tornadoes between Parker and Castle Rock," two towns south of Denver, the National Weather Service said in a bulletin.
It reported a large tornado in southern Arapahoe county, east of Denver, at 5:47 pm (2347 GMT).
Local television channel KUSA showed a huge funnel cloud touching ground in relative open country around Parker, about 40 kilometers (25 miles) southeast of downtown Denver.
