WESTPORT - A Westport teen has designed a smartphone app that predicts when snow days will happen.

Scott Pecoriello, 17, says he's always been fascinated with weather and forecasting, which was the inspiration behind his app, called Know Snow. 

The app features maps of Fairfield County and a list of towns, where users can see the odds of whether a school will be closed or not. Pecoriello says Know Snow is 84 percent accurate when it comes to predicting cancellations.
