Each dot is a city: the six largest cities in each state by the Census Bureau's 2024 estimates (Honolulu only in Hawaii) and Washington, D.C., worked out with the same rules as the calculator. The likelier a snow day, the bigger and darker the dot. Tap or click a state for its page. Every state has its own page: the list of states.

No snow days in sight

None of the 296 cities we check has even a 5% chance of a snow day on its next school day. A small town in the mountains or the snow belt can differ from its state's big cities: type your own ZIP code into the calculator.

This map shows the chance of a snow day on the next school day in 296 cities: the six largest in each state by the Census Bureau’s 2024 estimates (Honolulu only in Hawaii), and Washington, D.C. Every half hour the site works out each city with the same rules as the calculator: the National Weather Service forecast for that city, the snow, ice and cold expected before and during the school day, the Weather Service’s warnings, and the snow it usually takes to close schools there.

A big, dark blue dot is a likely snow day; a small grey ring is under 5%. Each state has its own page, with its cities, its normal snowfall and its rules on make-up days: click its shape on the map, or find it in the list of states. For your own school, type its ZIP code into the calculator: the snowiest towns are rarely their state’s biggest cities.

How is each city’s chance worked out?

The same way as the calculator’s. The forecast comes from the National Weather Service for each city. Snow that falls overnight and while buses run counts most; snow during the school day counts less, because it more often brings an early dismissal than a closed day. The total is compared with the snow that, by our rule of thumb, usually closes schools in that city, worked out from its normal snowfall in NOAA’s 1991–2020 climate normals: about half an inch in Atlanta, 3 inches in Washington, 11½ in Buffalo. Ice, bitter cold and Weather Service warnings raise the chance. Every rule is written out here.

Why can a city show under 5% while it is snowing?

The map looks at the next school day, not today. From 7 AM on a school day, that is tomorrow, and on a Friday it is Monday. The snow that counts falls between 6 AM the day before and 3 PM on the school day: all of it overnight and while buses run, 80% of it in the afternoon and evening before, and 35% of it that morning. So a storm that ends at noon counts for much less than one still falling at 6 AM, and Saturday’s snow does not count for Monday at all. A snowy city also needs much more snow to close than a city that rarely sees it.

Every city, state by state

The chance of a snow day, a late start or school as usual on the next school day in 296 U.S. cities (the six largest in each state, Honolulu only in Hawaii, and Washington, D.C.), with the snow forecast and the snowfall that usually closes schools there, worked out every half hour from the National Weather Service forecast by the calculator's published rules. Checked 3:07 PM EDT, Thursday.

Built from: National Weather Service API (api.weather.gov): forecast grids and alerts (National Weather Service); U.S. Climate Normals, 1991–2020 (National Centers for Environmental Information); City and Town Population Totals: 2020–2024 (United States Census Bureau).

Questions people ask

How often is the snow day map updated?

Every half hour, as long as the National Weather Service forecast comes through. The time of the latest check is above the map. A city whose forecast does not come through keeps its last numbers for up to three hours.

Why isn’t my town on the map?

The map shows each state’s largest cities, so that it can be worked out every half hour. The calculator covers every U.S. ZIP code area: type yours (for a PO box ZIP code, the ZIP code of the school’s street) to see your own school day.

Does a high chance mean school is closed?

No. Only your school district decides, and it tells families on its own website and app, by phone and on local TV and radio. The map shows what the forecast suggests.
