Ohio University officials cancelled Wednesday classes on all campuses due to extreme cold. 

The National Weather Service has forecasted extreme winter weather conditions between Tuesday and Thursday, including potential for extreme wind chill factors.

OU operations will remain open on Wednesday, and all faculty and staff members are expected to report. University officials anticipate that classes will resume as usual on Thursday. 

Before the cancellation, OU students signed a petition to cancel classes due to record cold temperatures. The petition received over 5,000 signatures before classes were officially cancelled.
