Every number, with its true age
SourceWhat it givesFetchedData ageStatus

Why this differs from your phone. A phone widget shows one blended number and hides its age. Here the big temperature is a physical measurement from the nearest ASOS/AWOS station (not a model), the rain timing comes from radar echoes sampled at your pixel (not an hourly forecast), and the confidence band is the live disagreement between five independent forecast models. When they diverge, you see it.
