Can you try a different source for the information?
For instance my weather app allows me to choose between NOAA/NWS, Accuweather, and a few other sources. In my case, when NOAA started reporting sporadically/shutting down, I just switched to Accuweather and have had no problems since.
Mind you, I'm using KDE on Mageia so I've no idea if you have that option. Just thought I'd try to help.
