I disagree that this is solved. Although Marco talks mostly about UX (being a UX guy), there is a lot to do on the backend, and I don't mean in weather prediction. For example, most of the data comes from a few sources (Bing even lists all of them, gross!). Why aren't these apps "grading" the forecasts after the fact and using that data to weigh which gets shown to the user? I can go on, there's a lot more than just UX needing to be worked on.
