I have them all...BeWeather Pro, Palamery Weather, Weather Bug Elite and some others. I think the best is a combination of two apps, the free Weather Channel app rocks for forecast of all kinds (10 day, hourly, etc...) and works great on my GN. The other must have for me is RainyDays. It's also free and it's only purpose is to provide radar. Other apps have radar, but this is a one click (to open it) and you have great, fast, zoomable, animated radar. The only thing about this app for me is that it installs defaulted to a satellite view (like the satellite view in Google Maps), but if you go to settings, you can uncheck that view and get the regular map look.
