Winter weather in Boston
Boston's biggest snow events come from nor'easters, which can intensify rapidly offshore and bring heavy snow and strong winds. Ocean-moderated temperatures sometimes keep the immediate coast near freezing while suburbs to the west stay colder.
Because coastal storms often peak overnight and into the morning, timing matters a great deal. A storm forecast to wind down by midnight gives crews time to clear streets; one peaking at 6 AM is far more likely to close schools.

Frequently asked questions
Is Boston Public Schools closed tomorrow?
SnowCall cannot tell you whether school is closed — only the district can. The estimate above is a forecast-based probability. For official closures and delays, check bostonpublicschools.org, the district's alert system, or local news.
How much snow does it take to close Boston Public Schools?
There is no published snowfall number. The model treats Boston as a "regular snow" area, where about 5" of overnight snow, 0.1" of ice, or a morning wind chill near -15°F makes a closure roughly a coin flip. Timing, temperature and wind can move that a lot.
Where does this forecast come from?
Hourly data from Open-Meteo for Boston (42.36, -71.06), four global weather models, and the National Weather Service's gridded snow and ice forecast and alerts.
