The National Weather Service in Colorado said Wednesday that Denver’s forecast is “snowy, windy, cold and dangerous.”
The forecast is based on the Denver-area region’s extreme cold.
A high of 29 degrees was expected Wednesday afternoon.
A record high of 28 degrees was set in Denver on Jan. 15, 1979, with an average high of 33 degrees.
“The cold snap has already started, but we still have plenty of snow in the mountains,” said Chris Lammi, director of the National Weather Services.
The forecast says there is a 1 in 4-in-5 chance of precipitation in the Denver area.
“Snowfall totals will be around 20 inches,” Lammis said.
“In Colorado, that means a lot of snow, and we’ve had a lot in the past.”

The snow is expected to be heavy in the Colorado Rockies and snowfall totals are expected to range from 6 inches to 20 inches, according to the weather service.

The weather service says there could be some scattered snowfall in parts of western Wyoming and central Idaho, but that the snow is likely to be light in the southern part of the state.
The National Highway Traffic Safety Administration says snowfall amounts will vary by county.
The average annual snowfall for the Denver region is about 6 inches.
The report said the cold snap is expected in parts that include the western part of Denver, as well as western Wyoming, the northern Colorado Plateau, and parts of the southern Colorado Plateaus.
It also predicts a low pressure system is likely in parts.
“We’re not expecting to see much snow in western Wyoming,” Lamps wrote.
“It’s not like it’s going to be any snow, but it’s not a chance.”
Lammes said the weather system is expected over the next few days to move westward and create an atmospheric high over northern Arizona.
That will bring a lot more snow to the Rockies.
“That’s going have a direct effect on snowpack in southern Arizona, and it’s also going to have a indirect effect in the north,” Lams said.
The severe cold weather in the Rockies and northern Arizona is expected Tuesday and Wednesday.
