Open your browser, and navigate to the cloud service at http://weatherservice.cloudapp.net. All you have to do is start a new forecast, select a location (by moving the map), and press the SAVE button to create a 3-day forecast of your own. It takes approximately 8 hours to complete the process, due to massive amount of computing behind the scenes. Once it’s done, you get detailed information on precipitation, temperature, snow, water vapor and surface and wind. (Note that the time required to complete the forecast process may be shortened to minutes once the new Windows Azure Hardware is available and the computations are done on multiple instances.)
