How much snow is forecast for Boulder, Colorado?
Our model shows 0.0mm of snowfall forecast for the next 24 hours in Boulder, Colorado, with temperatures around 6°C.
How accurate is the SnowSense snow day calculator?
SnowSense™ uses live Open-Meteo forecast data — aggregating NOAA (HRRR/GFS) and ECMWF models — with regional tolerance modifiers and storm timing analysis. Our confidence score reflects how decisively the conditions point toward (or away from) a closure.
Typical closure threshold
12–18 inches of wet snow
Boulder gets significant snowfall but also gets rapid clearing from dry air and Chinook winds. A foot of snow can fall and melt in 24–48 hours — which means districts here focus on the melt-freeze cycle (overnight ice on roads cleared yesterday) as much as on fresh accumulation. Temperature swings of 40–60°F in a single day are normal, and that's what actually determines road conditions in the morning.
Elevation, wind, and Boulder school decisions
Boulder sits at elevation, which means the air is drier and the snow is lighter and more easily plowed than eastern snow of equal depth. A six-inch powder event in Boulder is equivalent to maybe two inches of wet snow in the northeast — easier for plows, easier for drivers, less likely to close schools. What does close schools here is the subsequent melt/freeze: daytime sun melts cleared pavement, overnight cold refreezes it to black ice, and the morning drive is dangerous even though no new snow has fallen.
Nearby mountain districts see dramatically more snow than Boulder proper. Teachers who commute from the foothills or mountain towns may face impassable roads even when Boulder's roads are clear. That cross-district staffing problem sometimes drives closures that surprise parents in the city itself.
Typical winter in Boulder
Boulder averages 71 inches of snow per year but benefits from frequent Chinook wind events that can melt several inches in hours. Schools typically close 3–5 times per winter, primarily for storms that exceed plow capacity or generate ice conditions.
- Seasonal snowfall: 71 inches (mostly dry powder)
- Elevation: influences both snow density and daily temperature swings
- Primary closure trigger: ice on cleared pavement from melt/freeze cycles
- Secondary: foothills and mountain commuter staff unable to reach school
SnowSense™ models mountain-west melt/freeze dynamics explicitly — conditions that eastern snow-day models miss. Live probability for Boulder refreshes every 30 minutes.
