The day after Christmas brought cold temperatures to northwest Kansas that will likely stick around through the beginning of the new year.

The cold temperatures prompted wind chill advisories to be issued across the region from late Tuesday night to late Wednesday.

The National Weather Service warned wind chills from 10 p.m. Tuesday to 10 p.m. Wednesday could range from 10 to 20 degrees below zero across all of western Kansas.

Anyone who has to be out in the temperatures should make sure to cover their skin, as frostbite can occur in 30 minutes in those conditions, said Liz Vickery, forecaster with the Goodland National Weather Service.

A warm-up is possible toward the end of the week, Vickery said, but just how much remains to be seen. Tuesday morning’s data suggested almost a diagonal line intersecting the Goodland’s offices region, which includes 13 northwest Kansas counties and parts of Nebraska and Colorado.

Temperatures on Thursday could range from 30 northeast of that line to the upper 40s to the southwest. In the Hays area, temperatures in the mid- to upper 30s are expected.

“That could shift in the next couple of days,” Vickery said of the location of that line and the possible temperatures.

There’s only a slight chance for precipitation in that time. Snow showers are possible late Friday into Saturday.

“There is a slight concern for freezing fog,” Vickery said.

Temperatures will again drop as that front arrives, dropping to between 15 to 30 degrees. Lows will drop into the single digits, possibly to as low as minus 8 overnight Saturday, Vickery said.

That will again produce some dangerous wind chills.

“We could see negative wind chills to minus 20,” she said.

The American Red Cross offers the following tips for keeping safe in cold weather:

• Wear layers of lightweight clothing to stay warm. Gloves and a hat will help prevent loss of body heat.

• Bring pets indoors. If they can’t come inside, make sure they have enough shelter to keep warm and they can get to unfrozen water.

• Place space heaters on a level, hard surface 3 feet away from flammable materials such as paper, clothing, bedding, curtains or rugs.

• Don’t leave space heaters or fireplaces unattended. Use a glass or metal fire screen large enough to catch sparks and rolling logs with a fireplace.

• Run a trickle of water to help prevent plumbing from freezing. Open cabinet doors to allow warmer air to circulate around the plumbing.

• Keep your thermostat at the same temperature day and night to help prevent plumbing from freezing.

• Never use generators inside, including a basement or garage.

• Do not use a stove or oven to heat your home.
