Just in case anyone is interested, I released a windy plugin a few months back for WordPress, and have just updated it with new features. I actually started developing it initially when I saw this thread in the feedback and suggestions forum.
Plugin link: Ventus - Weather Map Widget & Shortcode
So anyone with a WordPress site who fancies an easy way to embed and customize the widget, I'd love if you gave it a go. It's free, and will remain so. :)
