How much snow it typically takes to cancel school in the U.S.

This is repost from 8 months ago, because someone decided to repost my work, and use an old, inaccurate version of it at that. So here’s the most recent version as of last year. I am still open to corrections and suggestions.

>To clear up a few things:

>4. The lightest green says “any snow” but also includes merely the prediction of snow. Also, this is snow accumulation over 24 hours/overnight.

>2. 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.**

>2. 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.

>3. Urban areas like Chicago and New York have more resources to clear snow and often need more to cause closings.

>6. To everyone saying “I grew up in so-and-so and we never closed school,” policies have changed in the last 20 years to make closing a much more common occurrence. Just because schools stayed open back then doesn’t mean they do these days.

>7. Hawaii does get snow! Just… [not where people live](http://media-cdn.tripadvisor.com/media/photo-s/01/52/9c/7d/mauna-kea-snow-in-hawaii.jpg).

>8. 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*.

>8. “School” refers to primary and secondary school (grade school, K-12), not colleges/universities.

>**All updates and fixes [here](http://ispol.com/sasha/snow/).**

>Updated 22:40 UTC 30 Jan 2014.

>Added Canada by popular request.
