Powered by NOAA / National Weather ServiceHeritage High School is a high school in Littleton, Colorado, part of Littleton School District No. 6 in the county of Arapahoe. 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 Heritage High School are almost always made at the district level. If Littleton School District No. 6 in the county of Arapahoe closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Littleton School District No. 6 in the county of Arapahoe forecast).
Suburban districts depend heavily on bus fleets covering a wide area of residential streets, which are plowed after main roads. Side-street conditions at 5 AM often decide the call.
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.
Colorado averages about 57 inches of snow per year. Front Range districts close most often during spring upslope storms that can dump 1-2 feet overnight.
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 Littleton School District No. 6 in the county of Arapahoe before acting on it.
