Famed Snow Day Calculator Stumped by NYC

If Mayor Bill de Blasio and Schools Chancellor Carmen Farina had checked David Sukhin's snow day calculator, things might have turned out differently for New York City public schools on Thursday.

Sukhin, a computer science student at MIT, created an algorithm when he was just in the sixth grade to predict whether or not his school would get a snow day. The website he created has never been wrong for his hometown of Watchung, New Jersey.

The calculator is now capable of predicting snow days for every zip code in the United States. On Thursday it forecast a 90 percent chance of school closures in New York City...but schools stayed open. In this interview, Sukhin said the program is constantly learning: "A day like this with over a foot of snow and no cancellation is definitely going to go into that algorithm."
