I just got through cleaning up a weather module that was originally for mambo.
It displays the current weather conditions for a specified station with a pretty icon.
See it in action here: http://www.sonicpling.net
With all options enabled: http://www.sonicpling.net/weather/weather-full.php
Get the zip file here: http://www.sonicpling.net/weather/weather.zip
there's a csv file included that list stations
It doesn't validate. and I don't have time to fix it right now. I may later, but if someone wants to jump in and do that I'd be happy to update the zip file.
