Snow in Grand Rapids
Grand Rapids averages 77.6 inches of snow a year (1991-2020 normal, NWS Grand Rapids annual climate report). Much of it is lake-effect snow: a west wind off Lake Michigan typically brings the heaviest bands from the lakeshore inland toward Grand Rapids (NWS Grand Rapids).
How Grand Rapids schools announce closures
Grand Rapids Public Schools tries to decide the evening before, but when the forecast is uncertain it finalizes and announces by 6 am. The superintendent makes the final call, and families hear by email, phone, text and the district app, with local TV carrying closings (GRPS winter weather procedures). On January 21, 2025, GRPS closed for road conditions and frigid temperatures (GRPS).
Reading the estimate in Grand Rapids
Level 4 of 4: Snow belt: schools are well prepared
For a suburban public school in Michigan, any one of these gives the model about an even chance of a closure on its own:
- 7.5 in of snow from 6 pm to 8 am (snow between 4 and 8 am counts extra)
- 0.15 in of ice from freezing rain, from the evening before to the end of the school day
- a wind chill of -30°F between midnight and 8 am
This is already the snowiest level, so elevation does not change it. These are model assumptions, not district rules. How the snow levels work.
Michigan is the model's snowiest level statewide. Enter the school's own ZIP code rather than the city name: the calculator reads the NWS forecast for that exact point, which is how a lake-effect band over one suburb and not another shows up.
