I see that there is a new group which has taken up supporting the Weather Display version of Weather34 originally written by Brian Underdown. The fact that Wunderground had changed the API made me look at whether to continue using the early script. I found the link to it at Weather-Watch.com and for those interested you'll find it at
http://wd34.weather-template.com/index.php. I've just installed the Beta version which uses the new API for the forecast and it seems to work OK. I had to rem out a couple of lines as storm warning error messages kept appearing, but otherwise it works well.
The link to my page if you want to see it is
