  • The lightest green says “any snow” but also includes merely the prediction of snow. Also, this is snow accumulation over 24 hours/overnight.
  • 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.
  • 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.
  • Hawaii does get snow! Just… not where people live
  • Data was taken from hundreds of various points from user responses on Reddit and interpolated using NOAA’s average annual snowfall days map.
