Get the only weather stat you really need: the wind chill or heat index. This number represents what it actually Feels Like outside, not just the temperature. Data comes from the nearest of 1,867 National Weather Service stations across the United States.
A wind chill reading is possible when the temperature is 50°F or colder and the wind is 3 mph or greater. The blue background is displayed when the number is the wind chill reading. Heat index readings begin at 80°F, and the app will have a red background. Gray means it Feels Like the real temperature, and so that is what is displayed.
