just recently had the no weather update problem. If i use the weather tab i cold get it based on my location but the main page was stuck showing weather only for "New York" no matter were i was. Tried the fixes i found here and a few other spots and got nowhere. Did some looking around and found the problem finally. Open your clock settings and make sure your selected time zone is "my location" once i made this switch the home page weather instantly was fixed.

this may not be everyones problem / solution but it worked for me so you may want to check it out.
