Weather Bonk

In one of my recent forays into somewhere or other, I ran across Weather Bonk, a very cool mashup of Google maps, regular weather forecasting, amateur weather stations, and webcams. You can enter a city name or a zip code, and then you'll get a page with a bunch of weather and geographically related information. The most interesting part is a Google map of the selected region, but showing temperatures from all of the amateur weather stations in that area. (These are private stations which publish their data to the U.S. Weather Service.) If you position your cursor over one of the temperatures, you get a semi-transparent box showing more detail about that station. Likewise, there may be little camera icons on the map. These represent webcams at those locations. If you position the cursor over those, it shows a small window containing the most recent image. Very cool.
