From the evening of October 27, 2009 through October 29, 2009, the Denver metro area was struck by a major, early winter snowstorm. The mountains and foothills to the immediate west of Denver were measuring the snowfall in feet while in the city more than a foot of snow fell in less than 72 hours. Here in Thornton we recorded 14.1 inches of snow during the event.
This time lapse video below was captured by our east facing webcam. It begins early Tuesday morning (October 27th) and runs through midnight on Thursday, October 29th. As it starts, you can see the first day started out nice enough but by evening the wind was blowing and rain was falling. That soon changed to snow and the snowstorm was in full force for two days.
That is very cool!
