Reddit user atrubetskoy has create a interesting map showing just how much snow it typically takes to keep kids home from school.
Some clarifications on the map from its creator, atrubetskoy, follow:
- In much of the Midwest and Great Plains, school closing often depends more on wind chill and temperature than on snow accumulation (“cold days”). Thus, this map may be misleading in those areas.
- Many jurisdictions in California and other western states have significantly varied snowfall, depending on elevation. This makes it difficult to find an “average” number, or often makes it misleading.
- Urban areas like Chicago and New York have more resources to clear snow and often need more to cause closings.
- Clarification: The lightest green says “any snow” but also includes merely the prediction of snow.
- Clarification II: This is snow accumulation over 24 hours/overnight.
- Hawaii does get snow! Just… not where people live.
- Data was taken from hundreds of various points from user responses and interpolated using NOAA’s average annual snowfall days map. Any corrections/additions are welcome, just give a decently specific location.
You should keep in mind that this map is just averages. [Reddit via The Atlantic]
