Powered by NOAA / National Weather ServicePierson High School is a high school in Nogales, Arizona, part of Nogales Unified District (4457). The forecast above uses the school's own coordinates, so it reflects conditions at this campus rather than an average across the wider area.
Closure decisions for Pierson High School are almost always made at the district level. If Nogales Unified District (4457) closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Nogales Unified District (4457) forecast).
Town districts sit between urban and rural conditions: main routes are usually cleared early, but outlying pickups can stay hazardous well past sunrise.
High schools start earliest, so they feel a storm before the rest of the district does — the first buses often roll while roads are still being treated. That earlier start time is one reason a district watching a morning storm may call the day off entirely rather than run a delay.
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 Nogales Unified District (4457) before acting on it.
