The web site Weather Underground offers iCal and RSS feeds of local weather that you can subscribe to in your Google Calendar or iCal.

Simply enter your zip code (if you live in the USA) or city name and country (if you don’t) into the search box at the top of the site’s front page.

iCal and RSS buttons appear at the top right under the ad banner. Command-Click on the iCal one and copy the link location. Command-Click in iCal’s calendar window, select Subscribe and paste the URL into the dialog that appears. All done.

You get a series of All Day events providing a forecast of the week ahead:

Personally I get all the weather I need from a Dashboard widget, but I understand how it would be useful to see the “Monsoon” bubble for the day on which you are entering details of the upcoming family BBQ.

You can do the same thing in Google’s Calendar by following the instruction in the post on Lifehacker from which this tip is lifted.

And you can easily use the RSS feed to get the same information into your news aggregator.
