I don't know what powers the "weather" that is shown on Google's customized page (google.com/ig), but it's misleading. Not the temperature so much, but the precipitation forecast.
It seems like the images are misleading too. The image for "Chance of Storms" makes it look like there is going to be heavy rain all day long.
Chance of storms:

Chance of showers:

I simply think the word "Chance" should show a bit of sun in there. Am I being anal? I feel the images are not clear.
Take care,
