The National Weather Service is predicting extreme wind chills in the -30 to -40 degree range on Wednesday. Faculty and staff working on campus over the semester break are encouraged to dress in layers and minimize time spent outdoors. To allow some drivers to park closer to their destinations, pay-per-stall surface parking spots on campus won't be ticketed. Locations include Lot 21 (west of the Armory), Lot 100 (near Lied Recreation Athletic Center) and the upper level of the East Campus Parking Deck.
