A cool feature of this web site is that you can generate links for specific locations which allows you to check the forecast for this location anytime with a single click. Click through for examples of Microsoft HQ, Google HQ, and the top of Mount Rainier.
It takes about a second to generate the forecast plots so you have to be a little patient. Also, presently forecasts are available only for the continental US and Eastern Asia — the language will change depending from where you click. Europe and other regions should be added soon.
