Due to some new security restrictions in WordPress (the application used to manage our website), it is no longer possible to embed another website such as WeatherLink. The only work-around to make embedding work is to upgrade our website to a business level at an increased cost.
My only other solution is to simply make the Current Weather a clickable link. As of today, you will see that link on our Home Page and also on the right side of the Menu.

Thanks to some good advice from Casey V., we got WeatherLink to work again on our home page.
