Snow Day is an app that predicts your ability to drive to work tomorrow. It uses forecast data from Forecast.io and distills the forecast down to a single datapoint, answering the question “Will I be able to drive to work tomorrow?” Snow Day continues to monitor the forecast in the background, and can optionally notify you when the driving prediction changes. **NEW: Apple Watch support! Check the driving forecast with a quick glance at your watch!** Note: This app is free with in-app adds. You can make a one-time in-app purchase to remove the ads and enable background notifications when the driving prediction changes.
