I hope this is allowed here, if not I kindly ask excuses from the webmaster. I like to check weather of potential travel destinations I might be heading to. Whereas many websites compile average data, I found a new one (still on Beta) that has the best graphs I've seen so far - WeatherSpark My favorite source is still Weather Underground, but their graphs are not good, especially if you want to show them to someone else. WeatherSpark doesn't have yet much data from many very specific locations, but it provides a lot of graphs in just one page about precipitation chances (not only quantity), cloud, wind, temperatures, chances of snow on the ground, daylight etc. Really nice travel tool :)
