First and foremost, it probably won't do much good to post a thread on the forums saying "My weather skin XXXX has stopped working, what do I need to change in it to get it working again?" The answer to that starts with "You will need to almost entirely re-write it", and ends with "No, we won't do it for you."
What I will do is provide a list of links here to skins that already used another source for the data, or have been re-written to work without wxdata.
I will try to keep the list current.
If you have a skin that you have, or know of, that you are sure still works, and want it included in this list, please send me a PM (private message) with a link to the skin. I will edit this post to add it.
DO NOT send me a PM for any other help with your current weather skin. I will absolutely just delete it without even reading it or responding in any way. I don't, and won't, provide any help on these forums except in public threads.
If you want some assistance with fixing your existing weather skin using the weather.com website, some tools are available at:
If you edit a skin created by someone else in order to get it working, this is perfectly fine as long as the original skin is not identified as being restricted for editing and distributing. Most Rainmeter skins are not. If you DO want to link to a skin you have changed / corrected, be sure your skin gives appropriate credit to the original author, and that you distribute your skin with a license like:
