Switzerland
Switzerland is a beautiful mountainous country in south-central Europe. The country is known for it's strident neutrality as much as it's chocolate, Alps, army knives and Misses. The weather is Alpine, of course, as the country is parked squarely in the Alps. This means it undulates depending on the elevation one finds oneself at. The valleys, including those in which the larger cities are found, can have a typically temperature warm summer/cold winter dichotomy, with all the humidity inherent with being as close to the Mediterranean as they are. OF course, the mountains are quite chilly and have snow on them year round at the peak. The valleys tend to have a "fohm" which is a micro sized version of the American Chinook, which means periods of warm air due to downsloping in the valleys.
I was in Switzerland for a couple of days in 2009 on my personal European adventure, and while I stayed in Zurich, it rained in heavy doses a couple of times, and I took the time to find MeteoSwiss, which was most helpful. Of course, how often do you get to walk the streets of Zurich? I got very wet anyways. MeteoSwiss is the colloquial name for the Federal Office of Meteorology and Climatology in Switzerland, essentially the Swiss Weather Service. As with most things Swiss, the site is very well organized. It comes with all the features one could ask for in a weather site as well, from the radar and satellite, to the available numerical weather models, like the COSMO, a proprietary model the meteorologists at MeteoSwiss rely on. My favorite page, for some reason is this one, a stark, unflinching look at the staff of Swiss meteorologists. Like I said, I used MeteoSwiss when I was in Europe, and it is one of the better weather sites around. I'm saying this in comparison not only to other governmental sites, but even to commercial sites. It's a solid site.
