Google Weather API gone?
Solution 1:
The Google Weather API seems to be "officially" dead, which is ironic to say, because it was never officially a supported API to begin with. There has been no official announcement from Google, but it should be noted that iGoogle is now using Wunderground's API for weather data.

So no, you're not seeing things. The Google Weather API is gone. I experienced the same thing. It's time to move on and find a suitable replacement.
