Northeast Ohio
Cleveland's east side sits inside one of the sharpest snowfall gradients in the country, so which suburb you check genuinely changes the answer. The estimate below is loaded with live Cleveland forecast data.

Local conditions
Cleveland lies on the south shore of Lake Erie, and the land east of the city rises onto the Appalachian Plateau. Cold air crossing the lake from the northwest picks up moisture and is then forced upward as it moves inland, which concentrates snowfall over Lake, Geauga and Ashtabula counties. The result is the northeast Ohio snowbelt: communities twenty miles east of downtown can be under a warning while the west side sees light snow from the identical storm. Because Lake Erie is shallow, a long cold spell can freeze it and shut the mechanism down for weeks.
What actually drives a decision
The gradient is steep enough that a single metro-wide forecast is close to useless for a school decision. Districts in Mentor, Chardon or Chagrin Falls face a different event from districts in Westlake or Lakewood. Use the location closest to the school and treat snowbelt forecasts as higher-variance.
The climb inland is what enhances the snow, and it also means colder surfaces and steeper roads in the eastern suburbs. Districts spanning the transition may run buses normally in one area while cancelling in another.
Northeast Ohio districts frequently use a two-hour delay to buy daylight and clearing time before buses run. A mid-range estimate here is often better read as delay pressure than as closure pressure, which makes the morning-timing factor especially informative.
When Lake Erie freezes over, lake-effect snow largely stops. When it stays open through a mild winter, bands continue. The same forecast pattern can therefore produce very different snowfall in different years, and the current forecast is the only reliable guide.
The forecast for the coordinates above is scored against six weighted factors: snow and ice, temperature, wind chill, morning timing, area and routes, and school level. Around Cleveland the rows that most often carry the number are snow and ice, morning timing, area and routes. Every factor appears in the result with its own value, score bar and published weight, so a percentage is never presented without the reasoning behind it. The methodology page documents each threshold, and the accuracy and limitations page sets out what the model cannot observe.
This site does not publish closure thresholds for any school system, because those are operational judgements rather than published numbers. What it can do is point you at the organisations that actually decide. Around Cleveland, OH those include:
Treat the estimate on this page as a reason to prepare and to keep checking, never as an announcement. A school system can close buildings, delay the start, cancel transportation only, dismiss early or move to a different learning format, and those outcomes are not interchangeable.

Cleveland questions
The estimate describes the forecast at the coordinates you selected. Because the snowbelt boundary runs through this metro, eastern districts can close while western districts operate normally, and a two-hour delay is a common first response on either side of the line.
It is the zone east and northeast of the city where lake-effect snow is greatly enhanced by both open water on Lake Erie and rising terrain inland. Snowfall there can be several times what falls on the west side of the metro in the same event.
Because it is a genuinely different forecast. The page requests data for specific coordinates, and the snowbelt gradient means locations twenty miles apart can expect substantially different snowfall, wind and timing.
No. It produces a single closure-pressure percentage. In northeast Ohio a mid-range result frequently corresponds to a delay rather than a closure, which is why the factor breakdown is shown alongside the number.
