The clouds and haze over the Denver area this morning are the result of impulses of cool moist air backing into northeastern Colorado from large storm systems in western Nebraska and Kansas, according to the National Weather Service.
Jim Kalina, a National Weather Service meteorologist in Boulder, said that during the past several nights large storm systems to the east of Colorado have sent the impulses of cool, moist air back west. This gives the Denver area cooler nighttime and early morning temperatures accompanied by clouds and some fog.
Kalina said a narrow plume of smoke from the 5,000-acre fire burning just north of Flagstaff, Arizona – centered near the Sunset Crater and Wupatki National Monuments – may also be adding to the haze.
He said the plume was flowing from Arizona north into Utah and then making a right turn toward Colorado. However, he said that latest observations indicate the plume is now starting to drift further to the north.
