Southwest Ohio
Cincinnati is far enough south that winter storms often arrive as a mix, and ice on the hills above the river is the recurring problem. The estimate below is loaded with live Cincinnati forecast data.

Local conditions
Cincinnati sits in the Ohio River valley, with the city built up onto steep hillsides above the water. Its southern position means many winter systems arrive with a layer of milder air aloft, so a single storm can deliver snow, sleet, freezing rain and plain rain in sequence. Cold air also settles into the valley and holds there, which keeps surfaces below freezing while precipitation falls through the warm layer above. Combine that with hillside streets and a road network built around river crossings and you get a metro where ice, not accumulation, tends to be the deciding factor.
What actually drives a decision
The relevant question is usually the sequence: snow first, then a change to sleet or freezing rain as warmer air arrives aloft. Read the temperature and precipitation values alongside snowfall, and note whether the snow-and-ice factor cites an icing signal rather than accumulation.
Roads climbing out of the valley are steep, and bridges lose heat from below and glaze first. A small amount of ice on those surfaces is enough to make specific bus routes unusable while flat roads elsewhere appear fine.
Significant snow is less of a weekly routine here than in northern Ohio, so the region's equipment and practice are calibrated to a different baseline. That is a genuine operational reality rather than a criticism, and it means a moderate event can produce more disruption than the same event farther north.
Cold air pooling in the valley also favours fog and rapid refreeze once a mild interval ends. Wet pavement at dusk can be black ice before the morning run, with no new precipitation at all.
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 Cincinnati the rows that most often carry the number are temperature, snow and ice, 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 Cincinnati, 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.

Cincinnati questions
The estimate reads the forecast, not the pavement. Cincinnati Public Schools and the suburban districts announce separately, and in an icing event a district on the hills can close while a neighbour a few miles away runs a delay.
The metro is built on hillsides above the river, and events often include ice rather than dry snow. Ice on a grade removes traction entirely, and it cannot be plowed away, so the disruptive threshold is lower than a snowfall total suggests.
Frequently snow first, then sleet, then freezing rain as milder air moves in above the valley, and sometimes plain rain to finish. That sequence matters more than any single total, because the decision is normally being made at the moment the changeover happens. Read the temperature row alongside the snowfall figure.
Choose the setting matching the school's road network. City neighbourhoods are Urban; districts like Mason or Lakota are better represented by Suburban, which the model treats as having somewhat longer and less rapidly treated routes.
