Displaying the weather icon is an experimental feature. It would be applied from the next version of MagicMirror (ver 2.20) which will be released the next July.
At this moment(with the current MagicMirror 2.19), you can try like this;
cd MagicMirror // Your MM installed directory
git pull // to update latest version. If your MM was quite old, you might need additional command `npm install`
git checkout develop // Change the branch to develop version.
You don’t need this method after July.
