It’s time to break out the winter coats: A weekend of chilly temperatures and slick, snow-packed roads arrived in Colorado Springs early Saturday morning.

An arctic blast is sweeping through much of the U.S., including the Pikes Peak region, bringing with it subzero temperatures.

Snow impacted local operations and road conditions on Saturday. KOAA meteorologist Casey Dorn said snowfall totals reached 4-5 inches throughout the Pikes Peak Region.

Several Mountain Metro Transit routes were not in service Saturday morning, waiting for the plows to clear the streets. City plows focused on primary roads during the morning and most main streets were passable by 10 a.m., snow manager Shaun Lucero said.

While major roads were passable by mid-morning, many streets were still covered in snow, making it hard for drivers to see the lane markings. The roads are expected to remain slick as temperatures continue to drop until Monday.

Those flying out of Colorado Saturday for the weekend likely faced delays, both in Colorado Springs and Denver. The Colorado Springs Airport reported over 15 delays and Denver International Airport reported over 450, according to FlightAware.

Some took advantage of the snow day. One mother took her kids sledding despite the shivering cold air. Temperatures were still in the teens, but the wind pushed the real feel temperature into single digits and negatives.

Gardenia Depina, with sleds in tow, said she isn’t the biggest fan of the cold coming from California, but she loves how excited her kids get.

“Normally on snow days I get dragged outside,” Depina said. “As long as (the kids) have warm coats on and their boots, I’m good with the cold.”

The high in Colorado Springs reached 19 degrees at 12:30 a.m. and the National Weather Service estimated the low hit minus 3. The record-low temperature for Jan. 18 was minus 20 in 1984. The average high for this time of year is 45 degrees and the average low is 19 degrees, according to the weather service.

The bitter cold set in Saturday evening with temperatures dropping to single digits once the sun set over the front range. A Cold Weather Advisory is in effect until 9 a.m. Tuesday morning.

“This is the coldest weather the city has seen in several years,” National Weather Service meteorologist Kyle Mozley said.

Colorado Springs will see a high of 12-13 degrees and a low of minus 5 on Sunday. A cold front will cause wind gusts up to 20 mph, dropping the wind chill down further. A round of light snow Sunday night into Monday is in the forecast, but flurries shouldn’t last past the morning, according to the weather service.

Monday is expected to be the coldest day of the week with a high of 6 degrees, potentially dropping to minus 10 degrees at night. Wind gusts will die down by the evening as the cold front passes. The air will start to warm up Tuesday with temperatures expected to hit the low 30s.
