I know that I changed my status bar weather source once before, but I can't remember how I did it. I just installed Palmary Weather and want to set that as my default temp. If it matters, I'm using LauncherPro plus.
I'd like to know this, too. Seems a waste to have more than one weather app operational.
I know the Beautiful Widget home clock/weather gives the option of Google weather or AccuWeather. I have a downloaded app for WeatherBug, which is my favorite because it has a station near where I live and the others don't.
I think that only certain weather apps can do this. I have WeatherBug Elite and you can turn on or off the temp feature in the notification bar. Palmary Weather Pro does not seem to have this feature. I sent them an email requesting that it be added...pinch to zoom on the radar maps was requested as well.
