Sorry to resurrect an old thread, however while setting this up for a site today I discovered Weather Underground no longer provides free APIs and don’t want people landing here from a web search wasting time when they’re looking for a free solution. You can still follow this method if you don’t mind paying for one of their subscription tiers, however for a quick and free option check out this post by user Duffanator. I tested it with some minor tweaking to what tags were being written to and it worked flawlessly for me.
