Can weather forecasting do better than "30 percent chance of showers"? What if it could tell you the minute it will start raining?

"Nowcasting" app Nooly claims it can tell you when precipitation will start and end with an accuracy of five minutes. It can also tell you when storms will intensify.

Nooly coverage, currently limited to the U.S. and Canada, can focus on an area within 0.4 square miles of your location.

It delivers 240 million predictions every five minutes based on a custom-designed algorithm that crunches satellite and radar data from NASA and NOAA. After a year of beta testing with some 50,000 users, it's now available for free to iOS and Android users.
