WeatherCenter 1.6 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The program relates to Lifestyle Tools.
From the developer:
WeatherCenter is designed to keep you updated on current weather conditions (in the US and Canada), as well as providing a simple way to get weather outlook information, all in a TV Weather-style format.
