The fog is likely to clear up by 9 a.m. otherwise skies are expected to be cloudy and snow is possible before 4 p.m. at a 40% chance with little or no accumulation expected.

Overnight temperatures are expected to drop to a low of 5 degrees with mostly cloudy skies and light breezes between 5 and 7 mph. There is also a 30% chance of snow before 11 p.m. and chance of flurries after 11 p.m. the agency said.

Snow is expected to stick around through the weekend with chances of more next week, the weather service predicts.

“Temperatures through the rest of the weekend will continue to be below average, maybe even record-breaking,” Denver Gazette news partner 9News reported. “Expect chilly highs in the teens Friday and Saturday, and dipping into the single-digits by Sunday.”
