When you first launch this Windows 8 app, nothing appears to happen. If you're on a mobile device, this is because your location details are being checked. On the desktop version of Bing Weather, though, the default location is Seattle, Washington, home of Microsoft. This is easily changed.
Simply click the arrow at the top of the Weather page and choose Places from the options that appear. Type in your current location and it will appear in the Favorites list. Click this entry to show it full-screen and press the Set as Default radio button at the bottom. (See also: Windows 8: the complete guide.)
Bing Weather recognises cities and towns in the UK, but not separate boroughs – for example, Greenwich in London was not an option, but Greenwich, Connecticut was. For more on the changes in Windows 8 and how to use them visit Windows 8 Advisor.
The weather forecast is provided by AccuWeather and is as true to its word as any forecast. As well as informing you of the current conditions and how any wind or cloud may affect how much colder that makes the temperature feel, there's an hour-by-hour summary of how the weather will develop during the day. In fact, details are provided for three-hourly intervals.
The likelihood of the predicted thunderstorm or downpour happening is given as a percentage for each day. The app shows you this visually too – scroll to the right to see the day's weather expressed by temperature, cloud cover, precipitation and as seen from a satellite.
Historical data showing temperature and rainfall for the month can also be viewed, while a World Weather map lets you see how much warmer it is elsewhere on the globe. For detailed advice on installing Windows 8 Release Preview, read our article: How to install Windows 8.
