When you’re traveling, it’s good to know what the weather is going to be like at your destination. Finding that out isn’t terribly hard, but Google has found a way to make it even easier. While you’re browsing Google Maps to find your route, you can click on Weather (it’s under Traffic, along with Photos and Terrain). This will bring up icons showing the current conditions and temperatures for a variety of cities in the area.
If you’re not content to simply have the current weather conditions, you can click on a specific location, and it will pop up with the extended forecast for that city. All of the information comes directly from Weather.com, which is where I generally look anyway, this just makes it even easier.
