Powered by NOAA / National Weather ServiceUniversity of Michigan-Ann Arbor is a college or university in Ann Arbor, Michigan. The forecast above uses the school's own coordinates, so it reflects conditions at this campus rather than an average across the wider area.
Urban districts usually have the best-treated roads and the shortest bus routes, so they tend to hold out longer before closing — but they also weigh sidewalk conditions and transit reliability for students who walk or ride public transport.
Michigan averages about 51 inches of snow per year. Lake-effect snow from Lakes Michigan, Huron, and Superior creates highly localized closure events — one district may close while a neighboring one stays open.
We score the live forecast at this location against the factors that drive closure calls: snowfall total and intensity, when the heaviest accumulation lands relative to the morning commute, ice and freezing rain, wind chill, and how confident the forecast models are. You get a probability for a full closure, a two-hour delay, and an early dismissal.
This is an independent forecast, not an official announcement. Confirm any closure with University of Michigan-Ann Arbor before acting on it.
