I noticed today that my system tray has N/A for rain data. I have a local Weather Underground station as my default but when I changed to Weatherbug and other Weather Underground stations they all have rain data. Where does the actual data come from? I'd always thought it was WA/WB itself and not the station but now I'm not sure. Since it's showing N/A would that be because there's a glitch with that station or they don't track it in the first place? This is a screen shot of the WU system tray.
