Why is my weather app giving me wrong data?

Episode 1653 (1:50:24)

Dave from Ridgecrest, CA
Yahoo Weather

Dave runs a Mac Mini and on Firefox, he's having an issue with his favorites. He links for Weather Data, and now the location data is all wrong. Leo says that since Dave is using a yahoo website, that could be part of the problem. Most weather people think that Yahoo's weather app is awful. Leo suggests trying a new website like Dark Sky. The browser may also be getting the wrong location data from the link, so it could be corrupted.
