Pros
Pro Accurate, detailed forecasts from crowdsourced data
Weather Underground crowdsources weather information. Anyone can set up a personal weather station and give that data to Weather Underground. A network of over 20.000 personal stations supplements roughly 10.000 National Weather Service stations. All collected data is run through a tool called BestForecasts that considers accuracy of 70 prediction models and creates a forecast from that process that's then presented to the end-user in a detailed way.
Cons
Con Somewhat overwhelming design
Weather Underground pushes an overwhelming amount of information at the user at first glance. Sometimes it is difficult to find exactly what you want on the go. Other applications such as Yahoo Weather are much easier to read. But the advantage to this is the wealth of raw information available.
