Same problem happened like a week ago for me. I fixed mine by a reg edit.

Hkey_current_user\Software\HTC\Manila Look for key Weather.ServerURLOverride

I added a .old to the Weather.ServerURLOverride and it worked

Changed it back about 3 days later and everything worked fine. I saw this post tried my update and sure enough not working. Added the .old and it updated just fine!

I just moved off the weather tab and back again. after exiting the reg edt program. Didn't even have to reboot to fix the update problem.

Hope it works for you as well.
