Pocket PC Thoughts found a real gem in Weather Watcher Mobile. While the free app doesn’t integrate into your Today screen, it does provide days of weather details relevant to your local area. I’ve used it for the past few days with nary an issue, but the software is a beta, so be forewarned.
With support for over 77,000 cities around the world, Weather Watcher Mobile has hourly and daily views as well as a detailed weather report for the next several days. All data comes from Weather.com and the interface is simple to use. You’ll need .NET Compact Framework 2.0 and a data or pass-through Internet connection in order to run Weather Watcher Mobile on your Windows Mobile device.
