In WeatherPro's case, it adds animated radar and satellite imagery for most of Europe and the USA, making this fairly easy to recommend at £3 in the Nokia Store. Screens and buy link below.

The main menu is in odd styling and shows up the application's origins away from Symbian - the Settings screen (not shown) is worse, by the way... WeatherPro is noteworthy for running in any of the EFIGS languages (English, French, Italian, German and Spanish) ; (right) you can drill down into any day's forecast to get three-hourly detailed reports, as shown. MeteoGroup's data seems to be fairly trustworthy.
