Ohio winter outlook
Ohio spans a lake-effect snowbelt in the northeast and a mixed-precipitation river valley in the southwest. Run the calculator for your city, then read which of those patterns applies.

Regional pattern
A single state-wide snowfall figure rarely explains a school decision here. These are the patterns worth knowing before reading any Ohio forecast.
East of Cleveland the land rises away from Lake Erie, and northwest winds crossing the lake dump their moisture as they climb. The result is one of the most abrupt snowfall gradients in the country: communities in Lake, Geauga and Ashtabula counties can be dealing with a significant event while the west side of the metro sees light snow. Any Ohio forecast comparison should start by asking which side of that line a district sits on.
The Ohio River valley is far enough south that many systems arrive with a warm layer aloft. Snow, sleet, freezing rain and plain rain can all fall from the same storm within a few hours. Districts in this part of the state deal with icing more often than deep snow, and they are relatively sensitive to it because significant snow is not a weekly routine.
Columbus and the surrounding counties get no help or hindrance from the lake. Winter weather here comes almost entirely from synoptic systems tracking out of the Plains or up the Ohio Valley, so forecast confidence tends to follow the confidence in that track. When a system does deliver, the flat and open countryside outside the outerbelt allows wind to drift snow back onto rural roads long after the snow stops.
Many Ohio districts use a two-hour delay as a first response, giving crews and daylight time to work before buses run. That means a moderate result from the calculator is often better read as a delay risk than a full-closure risk, and the morning-timing factor deserves particular attention here.
Permanent city pages
Each page loads its own coordinates, its own local closure factors and its own official sources. Any other Ohio community can be searched directly in the calculator above.
The percentage on this page is a weather-based planning estimate. It scores forecast snow and ice, temperature, wind chill, morning timing, broad area type and school level, and it shows each of those with its own value and published weight. It does not observe road treatment, staffing, building utilities or the judgement of the people who actually make the call. The methodology page documents every threshold and the accuracy and limitations page is explicit about the gaps.
No school system in Ohio publishes a snowfall number that triggers a closure, and this site does not invent one. Use the estimate to decide whether a backup plan is worth arranging, then let the official announcement decide what actually happens.

Ohio questions
It is the strip of higher ground east and northeast of Cleveland that receives greatly enhanced lake-effect snow when cold air crosses Lake Erie. The enhancement comes from both the open water and the rise in elevation inland, and it produces a very sharp difference in snowfall over a short distance.
Freezing rain creates a glaze that cannot be plowed away and makes hills, bridges and sidewalks hazardous almost immediately. Districts that see fewer severe snow events also have less equipment relative to the road network, so the practical threshold for disruption is lower.
No. It produces one closure-pressure estimate. A mid-range result in Ohio frequently corresponds to a delay rather than a closure, which is why the result page shows the underlying factors instead of only a verdict.
The individual district, community school or private school. County and state agencies may declare snow emergencies affecting travel, but they do not close schools; that decision and its announcement belong to the school system.
