Webpages on www.wunderground.com load incorrectly

The Weather Underground site pages simply do not load correctly. The format gets completely skewed & some sub-pages won't load at all. i'm not sure if HTTPS Everywhere causes the problem though it does note parenthetically in the rules menu that the site is "buggy." i never had a problem loading this site's pages before i installed https everywhere. i'm not a coder so i don't have a clue how to fix it. Thanks in advance if you can figure anything out--or offer a way to disable https everywhere for specific sites where it causes problems. i'm running chromium browser on the ubuntu linux platform.
