Snow in Cleveland
Cleveland averages 63.8 inches of snow a year (1991-2020 normal at the city's official airport station, NOAA), and it sits on the western edge of the snowbelt. NWS Cleveland identifies the primary snowbelt as eastern Cuyahoga, Lake, Geauga and Ashtabula counties (NWS Cleveland), so the east side and eastern suburbs often get much more lake-effect snow than the west side.
How Cleveland schools announce closures
The Cleveland Metropolitan School District tries to announce closures the night before, and otherwise decides no later than 5 am, notifying families through local media, its website and automated calls, texts and emails (CMSD inclement weather playbook). Its criteria include 5 to 10 inches of snow on the ground, 3 or more inches overnight on existing snow, ice, a wind chill of -15°F or colder and poor visibility (News 5 Cleveland).
Reading the estimate in Cleveland
Level 3 of 4: Snow every winter
For a suburban public school in Ohio, any one of these gives the model about an even chance of a closure on its own:
- 5 in of snow from 6 pm to 8 am (snow between 4 and 8 am counts extra)
- 0.1 in of ice from freezing rain, from the evening before to the end of the school day
- a wind chill of -20°F between midnight and 8 am
Places whose forecast grid point is above 1,800 m (about 5,900 ft) move up one level. These are model assumptions, not district rules. How the snow levels work.
Ohio uses one level statewide, so the model does not know Cleveland is next to the snowbelt. Lake-effect snow forecast for a ZIP code is counted, but the thresholds are the same as in southern Ohio.
Questions and answers
How does CMSD decide on a snow day?
It weighs snow on the ground and overnight, ice, wind chill and visibility, and aims to decide no later than 5 am (CMSD; News 5 Cleveland).
Why does the east side get more snow?
The primary snowbelt is in eastern Cuyahoga, Lake, Geauga and Ashtabula counties (NWS Cleveland).
Is the Cleveland snow day estimate an official closure notice?
No. It is an estimate from the National Weather Service forecast. Only the school district can close schools, so check its announcement before changing your plans. How accurate the estimate is.
