Overnight advisory: Temps around zero, wind chills at -20
Sure, it feels cold now, but a wind chill advisory officially begins at midnight and lasts until 9 a.m. Saturday.
The National Weather Service warns of wind chills that could hit 20 below zero. The overnight low temperature will be right around zero.
Frostbite can result as a result of skin exposed for just 30 minutes, and hypothermia can occur as well, the weather service warns.
It's expected to be cold in the suburbs all Saturday, with a high temperature around 12 and more winds making it feel worse. A warm-up comes Sunday, but 1 to 3 inches of snow could fall.
