Why bother, when you have a forecast?
Modern forecasts are excellent for the next 12–72 hours, but they don’t tell you what’s happening right now where you’re standing. That’s where reading the sky still matters — for hikers above treeline, boaters miles from shore, gardeners deciding whether to cover the tomatoes, anyone watching a thunderhead build on the horizon and wondering how long they have before it arrives.
And honestly, looking up is just a nicer way to live than refreshing an app.
