JGUI.net has released a plugin for your Today screen that provides weather information. MY|WEATHER will allow you to see current weather conditions, forecasts for the upcoming week and view reports in various styles. You set your area either by ZIP code or by city name and the application will auto-update when you are connected to the Internet. You can also collapse the application to a single line with only status and temperature to unclutter your Today screen.
MY|WEATHER can be purchased from our affiliate Handango for $17.99 USD. A trial version is also available.
