Iowa State maintains a [severe-weather and emergency-closings policy](https://www.policy.iastate.edu/policy/weather) and an [Environmental Health and Safety closings page](https://www.ehs.iastate.edu/weather/winter/closings) as its authoritative status sources. The post-Thanksgiving timing compounded the risk because students were traveling back to campus as the heaviest snow arrived.",

    "Iowa State canceled Monday, December 1, 2025 classes after a post-Thanksgiving storm dropped 10+ inches of snow across central Iowa",
    "The closure was coordinated across Iowa higher education, with Drake and Grinnell also closing the same day",
    "The storm's timing on the holiday return weekend put students on the roads as conditions deteriorated, a key driver of the cancellation decision"
