This will be followed by a Cold Weather Advisory in effect from noon on Sunday through 10 a.m. on Monday, with wind chills potentially dipping to around 13 below. Residents are urged to dress in layers, cover exposed skin, and use caution when traveling in the extreme cold conditions.

Why it matters

Dangerously low wind chills pose a serious risk of frostbite on exposed skin in as little as 30 minutes, especially for those spending extended time outdoors. The extreme cold can also create hazardous driving conditions and put those without adequate heat or shelter at risk.

The Cold Weather Advisory will then go into effect, lasting through 10 a.m. on Monday. Wind chills are expected to bottom out as low as 23 degrees below zero on Sunday morning, with 'very cold' conditions lingering into Monday when wind chills may still reach around 13 below.
