I've been using the usual weather network for the last many years to get my weather information. It's good and all but lacks some detail. Looking around for a better information source, I got turned on to Weather underground for my weather in the last month or so and I've been digging it - both for my phone app and on the website.
It offers much more detailed information than other websites, including a composite temperature/precipitation graph throughout the day, as well as moon phases, detailed super local weather on a map, live wind readings, and more details about the sunrise and sunset that is all valuable stuff for outdoor pursuits and planning.
