I have been a fan of the WeatherCenter 2.6.2 gadget and not been shy to promote it. The only problem was that the download on the link I gave does not work. But all is not lost..
Go to this page, translate it and click on the Download button. You can either run it from the page as I did, or save it and run it later.
It works in Windows 8 desktop and is way better than the Metro weather because you can use any one of six weather sources, whichever is best for your region. In Canada, the Weather Network resource is best
There are other gadgets on the site, some of which used to appear in the Windows Gadget Gallery.
I have corrected the link in the ‘Favourite Gadgets’ sidebar box too.
