This script uses Googles "secret" Weather api To gather some weather information and images. The information and images are then sent to a picture window and the image is copied and added to the Toolbar.
Using the Script:

Paste this code to a new Remote
Edit the top of the script so %MyLocation reflects your home location. (Keep in mind that this does not accept airport codes. It's also a little picky, so it's better to use the two character abbreviation for your country. ie. CA for Canada. If you are in USA zipcodes work fine.)
Save the script.
Right click channel or status, goto Google Weather, and click On.
Select dialog to search other cities or to see your forecast.

Additional information:

Hover over the weather icon on the toolbar for more weather info.
Click the weather icon to open the forecast dialog.
You may also change the temperature from F to C. (See the setup at the top of the script)
