You were missing the JQuery plugging.
But even when I added it I was getting errors
So I linked directly to the weather and jQuery plugins in the head.
<script src='http://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js'></script>

Also who ever wrote the style code uses html tag in the styles to plant the background image.
This does not work,( within hype) and I have not looked at it too closely but imho is not something I would do.
I changed that to use the #weather id of the rectangle.
Also in the JS they use html as a global var.
I have changed this to
weatherHTML
