This is a big weekend for many South Bend-area college students. That's because St. Mary's College, Holy Cross College and the University of Notre Dame are all holding their commencement ceremonies this weekend. The ceremony for Holy Cross College will begin at 11 AM Saturday. The ceremony for St. Mary's College will begin at 12 PM Saturday. The ceremony for Notre Dame will begin at 10 AM on Sunday.
Unfortunately, the weather will not entirely cooperate for these ceremonies. That is especially true for the two commencements being held on Saturday. Temperatures will be mild in the middle and upper 60s, winds will be relatively light and the humidity won't be extremely high. However, there will be scattered rain showers across the region. Will it rain the entire morning and afternoon? No, but rain showers are very much possible. Thankfully, thunderstorms are severe weather do not appear likely on Saturday at this time.
The same cannot be said for Sunday in regards to the chance of storms and severe weather. Those along and south of U.S. 30 have been placed in a "Marginal Risk" for severe thunderstorms Sunday and Sunday night. That is the lowest of the severe weather threat categories, but suggests that the Storm Prediction Center does believe we will have the parameters in place to support at least a few strong to severe thunderstorms. The best chance of any strong or severe storms will be after 6 PM across central Illinois into central and southern Indiana. At this time, the weather during Notre Dame's commencement ceremony looks dry and comfortable. Temperatures will be in the middle and upper 60s under mostly cloudy skies with light winds and tolerable humidity levels.
