Google Maps Wants to Talk about the Weather
The weather layer shows current temperatures and conditions all over the planet, so unless the forecasts suddenly changes, you'll know if you're heading into a snowstorm on your cross-country trip.
You access the weather layer by hovering over the widget in the upper right corner and selecting it from the list of options. Zoom out to see current temps and conditions (as represented by self-explanatory icons) as provided by weather.com. Cloud coverage is included too, courtesy of the U.S. Naval Research Lab, and Google says if you look closely, you can see if its day or night around the world by looking at the sun and moon icons, which could prove particularly helpful for those in a long distance relationship.
Yes, there really is a Kamalazoo!
There's a bit of interactive play baked into the weather layer, too. Clicking on an icon for any given city brings up a window that displays more detailed data, such as humidity and wind conditions, and a four-day forecast.
