I have (with my old iOS 7.1.2 and 8.1 jailbreaks) been using Weatherboard. It lets you place the animated weather from the Weather app directly over your wallpaper on both the lockscreen and the homescreen (or either or). Weatherboard does what Forecast promised but did not deliver on in iOS 7 - namely live weather over your own wallpaper. Weatherboard 2, will do the same AND do what Forecast was doing by put a forecast on the lockscreen! Additionally, it will also be LockHTML friendly so you can still put other stuff in there on your lockscreen as well. So…Forecast is dead…long live Weatherboard 2!!!
