Typical closure threshold
Any measurable snow
Snow in Tucson is effectively a zero-probability event most winters. The southwest desert climate produces warm winter days and chilly nights, and the rare winter-precipitation event is typically rain. When frozen precipitation does arrive — an event that might happen once every 5–10 years — it closes schools immediately because no winter infrastructure exists.
Tucson's winter reality
Arizona's desert southwest climate means Tucson's school-year is effectively winter-free. Districts here don't staff for closures, don't maintain plow fleets, and don't have established cold-weather protocols. When a genuinely rare winter event occurs, the closure is often multi-day simply because normal operations can't resume until thaw.
Nearby high-elevation areas (northern AZ, southern NM mountains, the Nevada high desert) can receive significant snow, but Tucson itself sits well below the snow line. The closest a Tucson parent gets to winter weather is usually a thick early-morning fog or a rare frost advisory.

Why nearby places may decide differently
Tucson can wait longer on borderline calls than Chandler
Tucson runs a much larger urban operation, so transit dependencies, staffing, and the downstream cost of closure all push decision-makers to hold off unless the forecast clearly threatens the morning commute.
Tucson and Mesa often diverge on marginal storms
That usually comes down to bus-route exposure, local hilliness, and how quickly each district can clear secondary roads rather than to headline snowfall totals alone.
