Hear that? That's the sound of Google making another type of online service obsolete. Google today announced an update to Google maps that, working with Weather.com, will show you what kind of conditions you'll be looking at for your weekend trip to the mountains. All you've got to do is open up Google Maps, type in your address, and select the Weather layer from the list of options in the upper right-hand corner of your screen. Current temperatures and conditions are shown all around the world and Google hopes this will make travel easier (or at least a bit better planned out) than ever before.
