Any measurable snow
Snow in Flagstaff 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.
Arizona's desert southwest climate means Flagstaff'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 Flagstaff itself sits well below the snow line. The closest a Flagstaff parent gets to winter weather is usually a thick early-morning fog or a rare frost advisory.
Flagstaff averages 90 inches of snow per year — essentially none. Schools rarely close for winter weather in any given year.
