Will Montgomery County Public Schools close tomorrow? Live snow-day probability for Rockville, Maryland — updated every 30 minutes with the latest forecast.
It's 59°F — no snow day expected.
Montgomery County Public Schools operates across the entire Maryland county containing Rockville, which means weather conditions can vary dramatically inside a single district. A storm that drops 8 inches on the northern half can produce only 2 inches in the southern half, but the district has to make a single call for every school. Administrators typically dispatch transportation crews along sample bus routes between 3 and 5 a.m. to assess actual road conditions rather than relying solely on forecast totals.
The closure decision usually comes from the Superintendent's office in consultation with the transportation director and (for severe events) county emergency management. Montgomery County Public Schools announces closures by 5:30 a.m. on the district website, automated phone tree, and local TV stations. Two-hour delays are more common than full closures here, because the size of the district means partial-day operations save instructional time when conditions are borderline.
Rockville has one of the lowest snow-closure thresholds of any region in the country. Districts here close for events that would be a non-story in Boston or Buffalo — not because of poor planning, but because mid-Atlantic winter infrastructure is sized for rare snow, ice events are more common than pure-snow events, and the rain/snow line shifts constantly through the region during storms. Montgomery County Public Schools serves 159,000 students across Maryland, which makes closure decisions consequential — but the district's scale also gives it the resources (plow contracts, transportation depth, communication infrastructure) to keep schools open through events that would close smaller districts.
Montgomery County Public Schools is a county-wide school district serving Rockville, Maryland and the surrounding community. The district operates within the broader Rockville school-closure ecosystem, where the city's climate (averaging 20 inches of snowfall per year) sets the baseline for how often weather events trigger closures.
