From the University Instagram Page:

"A wind chill warning is in effect from now until 6 p.m. Thursday (1/31/19). Wind chills as low as 20 or 30 degrees below zero are expected. Based on current conditions, the University will remain open and operational. However, we will continue to monitor the weather..."

Wind chills of 20 to 40 below zero are possible through Thursday morning. At those temperatures, it can take less than 10 minutes to develop frostbite on any exposed skin. Given the icy and slippery conditions, commutes to class from residence halls and parking lots can exceed 10 minutes.
