It’s a big weekend for the University of Montana in Missoula, as organizers get ready for the 116th commencement ceremony. However, officials are keeping a close eye on the forecasts.

NBC Montana spoke with officials about the possibility of severe weather. We’re told lightning strikes would mean attendees would be asked to leave the ceremony at Washington-Grizzly stadium. Heavy rain may prompt the University’s president to shorten the ceremony.

The main commencement will be outdoors at Washington-Grizzly stadium, and on Friday afternoon crews set up tents to keep grads dry. The whole event starts with a breakfast at 7:30 a.m., then ceremonies at the stadium kick off at 10 a.m. Attendees are asked to be seated by 9:30 a.m.

“It’s just that time to send everybody off and say 'Great job, go do good things in the world,'” said University Registrar Edwin Johnson.

Folks hoping to catch the ceremony but can’t make it can stream the ceremony on the University’s website.
