The advisory is slated to remain in effect until 12 p.m. Monday, with wind chills as low as -25 degrees possible.
The frigid temperatures pose an extreme danger, with wind chill values in that range having the potential to cause frostbite to exposed skin in as little as 30 minutes.

In addition to bitterly cold wind chill values, actual temperatures will be at their lowest levels of the season thus far, with single-digit highs forecasted for both Monday and Tuesday.
Overnight lows Monday into Tuesday could reach as low as -5 degrees, according to the NWS.
