Get ad-free weather conditions from the National Oceanic and Atmospheric Administration. This following script can be used as an example and modified to fit your site. Instructions are embedded in comments in the script.
If your site has a lot of traffic, then you may want to download the weather xml file every hour (it is only updated once an hour anyway) by using the following cron line and changing the script to read the local xml file.
