For ease of weather research for photography I have combined the weather map from Dark Sky together with weather widgets from Willy Weather on a single page.
The Dark Sky weather app is set to show rain forecast but can also show cloud cover, temperature, dew points, etc.
The location specific forecasts are split between Coastal and Inland. They both have general weather forecasts and rain % but also provide sunrise and sunset times for ease. In addition, the Coastal locations have tide times.
