Dangerously cold wind chills as low as 20 to 25 below zero are expected early this week, prompting weather officials to urge special caution to guard against the potential for frostbite and other effects of extreme cold.

The National Weather Service issued cold weather advisory starting at 9 p.m. on Monday until noon on Tuesday.

Monday and Tuesday have the lowest expected temperatures during the week. Monday night into Tuesday morning will see wind chill values as low as 17 below zero. The day will see a high of 12 and a low of six by nighttime. Temperatures will start to rise slightly by Tuesday night, according to National Weather Service Meteorologist Ricky Castro.

Frostbite can occur on uncovered skin in as little as 30 minutes. Climate experts advise the following precautions:

"If you're dressed in layers, but then don't protect the extremities, that's the biggest risk factor for most people, the potential for frostbite development," Castro said.

Only light snow or flurries are expected Wednesday afternoon -- which will see less extreme weather with a high near 16 degrees. Castro advises that any snow coating can cause slippery travel conditions in extreme cold.

Recovery in temperatures to above freezing will happen by Saturday, with numbers back in the upper 20s.
