Powered by NOAA / National Weather ServiceTucson Unified District (4403) serves the Tucson area in Arizona, covering 102 schools. When winter weather threatens, the closure decision is made district-wide — which is why the forecast above is centred on the district itself rather than any single campus.
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.
We pull the live forecast for the district's own coordinates and score the factors that drive a closure call: snowfall accumulation and its timing relative to the morning bus run, ice and freezing rain, wind chill, and forecast confidence. The result is a probability for a full closure, a two-hour delay, and an early dismissal.
Districts announce closures between roughly 5 AM and 6 AM, working from conditions on the ground rather than the previous evening's forecast. Weather models are most reliable inside 24 hours, so checking after 6 PM the night before gives you the most accurate read.
This is an independent prediction, not an announcement. Always confirm a closure with Tucson Unified District (4403) directly before acting on it.
