Real-time probability that schools in Maple Grove, Minnesota will be cancelled tomorrow, based on live forecast data and local closure thresholds.
Snow day season is currently inactive in your region.
10–18 inches, or wind chill below −30°F
Maple Grove has one of the highest snow-closure thresholds in the country. Districts here regularly hold classes through 6–8 inch events that would close schools in any mid-Atlantic city. The real closure trigger in Minnesota is wind chill: sustained values below −30°F trigger "cold day" cancellations under state safety guidance, because school buses and waiting children can't safely function in polar-vortex cold regardless of snow cover.
Schools in Minnesota are built — both culturally and infrastructurally — for severe winter. Bus fleets have engine-block heaters, diesel is blended for sub-zero temperatures, and most families have winter gear good to −20°F. This means snow accumulation alone rarely closes Maple Grove schools. A foot of powder in Maple Grove produces clean, drivable roads within hours because plow fleets are sized for this climate.
What actually stops Maple Grove schools is polar-vortex cold — when Arctic air masses drop south from Manitoba and wind chills reach −30°F or lower. Under those conditions, a child left at a bus stop can frostbite in minutes. The National Weather Service issues "dangerous wind chill" advisories that trigger district-level reviews, and when sustained wind chills are forecast below −35°F, closures are almost automatic.
Maple Grove averages 54 inches of snow per year across a 5–6 month winter season. Despite that volume, schools typically close only 1–3 times per winter, with cold-day closures outnumbering snow-day closures.
SnowSense™ models wind-chill-driven closures separately from accumulation-driven closures because Minnesota is different. Live probability for Maple Grove refreshes every 30 minutes and accounts for both.
