All morning activities and athletic practices scheduled for Thursday morning are also cancelled. Naperville North has yet to announce whether after-school activities and athletics will take place.

The National Weather Service issued a wind chill advisory for DuPage County until 12 p.m. tomorrow. Wind chill values are expected to plummet 25 to 30 degrees below zero during this time. Frostbite can occur within minutes on exposed skin.
