How Much Snow Does It Take to Cancel School in Your City? Check This Map

We all saw how a couple of inches of snow crippled Atlanta this week. Some cities, mostly in the South, simply aren't equipped to handle any snow at all — a little bit of accumulation brings them to a grinding halt — while other cities laugh in the face of snow build-up measured by the foot. 

Which brings up an important question: Just how much snow does it take to cancel school in a city? Well, Reddit user atrubetskoy has the answer. Check it out:

Atrubetskoy put together this map using data from "hundreds of various points from user responses" which was then "interpolated using NOAA's average annual snowfall days map."

It turns out that snowfall is all relative. Southern cities rarely see snowfall, so just a few inches over a period of 24 hours can close schools. But western New York gets pounded with lake effect every year, so it takes two feet or more to give kids a day off.

The map's creator does make a few clarifications, noting that in some parts of the country, like the Midwest, "school closing often depends more on wind chill and temperature than on snow accumulation," and that "urban areas like Chicago and New York have more resources to clear snow and often need more to cause closings."

The best clarification, though, is that schools in the light green area on the map may close at "merely the prediction of snow." That's adorable.
