Ever since moving to the San Francisco Bay Area, I have been wishing there was a site where I could go to easily figure out where around here it's sunny right now... well today I found that site: Weather Bonk!
Not only does it have a great map of all the local weather cams, it has the option to turn on a cloud layer which shows where it's cloudy (see image below).
Today it looks like we would have to drive to San Jose, or Mt. Diablo State Park to find some sun and avoid the fog... ah, San Francisco!
