Winter weather in Philadelphia
Philadelphia sits near the I-95 corridor's typical rain–snow line, so many storms start as snow and change to sleet or rain. Forecast totals for the city are often lower and less certain than for the northern and western suburbs.
When temperatures hover near freezing, the model lowers the weight of the snowfall; when freezing rain is in the forecast, ice can raise odds sharply even with little snow.

Frequently asked questions
Is The School District of Philadelphia 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 philasd.org, the district's alert system, or local news.
How much snow does it take to close The School District of Philadelphia?
There is no published snowfall number. The model treats Philadelphia 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 Philadelphia (39.95, -75.17), four global weather models, and the National Weather Service's gridded snow and ice forecast and alerts.
