Cool, interactive weather website

Weatherspark is a really neat site that allows you to create interactive graphs of weather forecasts and long term trends. So, for instance, I can compare three different weather forecasts for my weekend. I can also go look at long-term climate changes in my region—where the mean temperature is on track to increase by more than 3 degrees F (and probably closer to 4 degrees) between 1949 and 2049. There's lots more neat stuff you can do with this this site. It looks like it could easily be a rabbit hole of random fact generation. It does, however, seem to require Flash. (Via Dan Zarrella)
