Should You Bring An Umbrella?

A future app, trying to get funding through Kickstarter, promises to give you short-term weather predictions for your exact location:

It might tell you that it will start raining in 8 minutes, with the rain lasting for 15 minutes followed by a 25 minute break. … [T]he catch is that it only works over a short period of time: a half hour to an hour in the future. But, as it turns out, this timespan is crucially important. Our lives are filled with short-term outdoor activities: Travelling to and from work, walking the dog, lunch with friends, outdoor sports, etc.
