I'm in the SF Bay Area I was able to get weather forecast with TP but I do I know it's the correct one? I mean it was just there after I installed it. Also How do I get the 12hr time format instead of the 24hrs format?
TodayPlus comes with the weather for London by default. You need to change it for your area. Here's how to do it: http://www.dark-mojo.com/TodayPlus/viewtopic.php?p=212#212
