Many skins are using weather.com and they rely on the API key which sometimes gets changed. Many modern weather skins will have a WeatherComJSONVariables.inc file or a separate skin with settings where you can change the API key. But you mostly probably will need to look around the .ini and .inc files and replace the old key with the working one.
At the moment of writing, the working API key is:
21d8a80b3d6b444998a80b3d6b1449d3
After changing the key - save the file and refresh your skin.
2. Try another weather skin.
Try this skin that is 100% working right after you install it. No configuration needed.
