Headed outside to play tennis despite a regional forecast for rain? Check out a new app from Ourcast first. Those gray clouds may not rain on your clay (or whatever your surface).
Ourcast offers hyper-local forecasts in any location you choose with minute-to-minute rain start or stop times within a two hour window. It's surprisingly accurate.
Learn how it works (statistics and crowdsourcing), via this article in Mashable.
The Ourcast app is free and available in the iTunes store.
