A hat and gloves are a must for those going outdoors, as exposed skin could be subject to frost bite in as little as 30 minutes, according to the weather service. Hypothermia also could occur without proper protection from the elements.

Most of the region’s colleges and universities canceled classes Wednesday.

Schools cancelling both day and evening classes for Wednesday include the University of Pittsburgh , Carnegie Mellon, Chatham, Robert Morris, Slippery Rock, LaRoche College, Westmoreland County Community College, Community College of Allegheny County, and Indiana University of Pennsylvania.

Duquesne University and California University of Pennsylvania announced classes at their campuses would be canceled Wednesday and Thursday.
