Weather is a simple Chrome extension that gives you the local forecast with a single click on the extension's toolbar button. You'll see the temperature and current conditions on the button itself, updated regularly, but click it for a full expanded forecast, using data from Forecast.io.
Since the data comes from Forecast.io, one of our favourite weather sites, you can trust that it's accurate. The extension will pinpoint your location automatically, so you don't have to tell it (although you can if you want to), and once you click on it, you'll see current conditions on top, an hourly forecast just below that with icons that show you projected conditions, and then a five-day forecast with highs and lows, along with conditions and precipitation chance for the rest of the week.
If you're planning a trip or just want to know if you'll need your umbrella when you leave the house, a quick check of the weather is a must, and while looking out the window is great, it won't tell you whether it's going to rain in an hour, or tomorrow. You could always just Google "weather" and get similar results, but Weather puts all that information right into Chrome, a single click away. It's simple, free, and it works.
