Is there any weather predicting/current download for the Mac for free?

I want to find a weather predicting/current weather download for the Mac for free. Can anybody help me? I have searched Google and downloaded "Meteorologist" but, so far it hasn't really worked. Please. Somebody HELP!|||i would go into the App store on your computer and download Swackett. It give you prediction and the current. It also tells you what if really feels like outside.
