Winter weather in Seattle
Snow is infrequent in Seattle, and the city's steep hills make even small accumulations hard on buses. When cold air from the interior meets Pacific moisture, a couple of inches — or freezing rain — can be enough to disrupt school.
Puget Sound convergence zones can concentrate snow over a narrow strip, so totals can vary widely between neighborhoods. Expect lower confidence and check again close to the event.

Frequently asked questions
Is Seattle 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 seattleschools.org, the district's alert system, or local news.
How much snow does it take to close Seattle Public Schools?
There is no published snowfall number. The model treats Seattle as a "rarely sees snow" area, where about 1" of overnight snow, 0.03" of ice, or a morning wind chill near 10°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 Seattle (47.61, -122.33), four global weather models, and the National Weather Service's gridded snow and ice forecast and alerts.
