Try Forecast on Cydia, or if you are not jailbroken, you can get widgets via the Notification Center. Try the native iOS weather app widget, or download the Dark Sky app from the App Store for $3.99. It's pretty neat!
Get BeWeather 2. Great customizable weather app. Shows weather notifications each hour on the lock screen while the phone is locked. Also notifications on the NC screen and great widgets as well. Severe weather and other special alerts show on the lock screen. It's $2.99, and worth every penny.

Thank you guys, I'll check them out. If you guys want a cool one also, I suggest weatherboard . It puts the weather outside on your lock screen picture in a cool way, if I knew how to post pics I would show you lol
