Weather Network app claims it can tell you when it is going to rain

We’re not quite through 2015 yet, so app developers still have time to make the prophecies foretold by director Robert Zemeckis’ documentary Back to the Future: Part II come true. And to that end, The Weather Network’s latest app update uses radar and algorithms to predict when, exactly, it is going to start and stop raining.

The new feature, appropriately called “Rain Start Stop,” claims to give you a few hours to finalize the details on your outdoor activities.

“Rain Start Stop will tell you when precipitation is expected to start and stop in the next 3 hours with a precision of 15 minutes,” says Weather Network meteorologist Elena Lappo in a press release. “It will also provide the type of precipitation (rain, sleet or snow) that is expected as well as how heavy it will be.”
