Fox News meteorologist Janice Dean says an incredible day of weather is unfolding across the country on Tuesday, as a major winter storm develops across the Rockies and a major wildfire threat grows hundreds of miles to the West.
Denver temps hit 91 degrees on Labor Day, but the Rockies are seeing quite different conditions less than 24 hours later.
Fox News meteorologist Janice Dean said an unusually cold air mass is rolling across the Rockies and the Great Plains today, sending temperatures plummeting 50-70 degrees colder than the last couple of days.
