Powered by NOAA / National Weather ServiceSt. Vrain Valley School District No. Re1J serves Longmont and the surrounding area in Colorado, covering 54 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.
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.
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 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 St. Vrain Valley School District No. Re1J directly before acting on it.
