Tomorrow's closure signal
Your Snow Day Forecast
Boston school decisions depend on nor'easter storm timing, coastal tide levels, snow clearance on narrow historic streets, and student pedestrian safety.

How Accurate Are Predictions?
Snow Day AI is designed to explain uncertainty instead of pretending a district decision is guaranteed.
Confidence System
Each forecast carries a confidence level based on forecast completeness, snow and ice severity, timing consistency, and how close the storm is to the commute window.
District Context
Two districts with identical weather can react differently. Bus dependence, road networks, terrain, and historical caution matter.
Live Dependency
Accuracy improves as storms approach because short-range snowfall, freezing rain, wind, and visibility guidance becomes more stable.
How Boston Snow Day Predictions Work
Boston snow day predictions are highly sensitive to coastal storm mechanics. Nor'easters bring intense bands of heavy, wet snow, strong winds, and coastal flooding. The narrow, historic layout of Boston streets makes plowing slow and difficult, often leading to earlier school closure decisions. SnowDayAI tracks storm path, coastal wind speeds, and road temperatures.
Boston Closure Factors
Key indicators include the timing of the heaviest snow band, whether the snow is dry or heavy/wet, coastal storm surge risks, MBTA trolley and bus status, and pedestrian sidewalk conditions.
Boston Delay vs Closure
Delays can be used if storm bands clear out by 4:00 a.m. allowing city crews to treat major roads. However, heavy nor'easters that continue into the morning commute almost always result in full closures to keep buses off narrow streets.
Boston Forecast Uncertainty
The rain-snow line frequently sits near Boston. A shift of just 10-20 miles can turn a forecasted foot of snow into a rainy, slushy mess. That is why SnowDayAI monitors confidence levels and updates hourly.
Snow day FAQ
Boston Snow Day FAQ
It uses live winter weather forecasts, coastal wind speeds, BPS response history, and commute timing. It is a predictive utility, not an official Boston Public Schools announcement.
Nor'easters bring heavy, wet snow that can weigh down power lines, create high coastal winds, and flood low-lying streets, raising the likelihood of a closure.
Heavy coastal snow exceeding 6 inches, significant freezing rain/glaze ice, high wind warnings, or extreme wind chills that threaten students at bus stops.
The rain-snow boundary is highly volatile. If temperatures rise even slightly above freezing, snow totals decrease, lowering the probability of closure.
Yes. Searching by a specific Boston neighborhood ZIP code provides a highly localized forecast while retaining the general BPS district profile behavior.
