Why Weather is the thinking weather app—for the weather-curious and the weather-nerdy. We explain the science behind the forecast, and the uncertainty behind the science. Most weather apps give you the play-by-play, we include the color commentary. MEET SKY Why Weather is the only weather app with an AI meteorologist you can actually talk to. Ask Sky why a front is moving in, what a radar pattern means, why pressure is dropping, or what a hook echo looks like. Sky explains the why, not just the what. TODAY'S WEATHER STORY Tap "Today's weather story" on the forecast screen—or your daily morning notification—and Sky writes a short narrative explaining what's actually going to happen. Not just numbers and icons: the why behind the day. What the front is doing, what to plan around, whether the rain is for real or just hedging. The same story that arrives in your morning notification is one tap deep into Sky's view. FORECAST IN FLUX When the National Weather Service explicitly hedges in their forecast discussion, we flag it. When a station nearby observes different conditions than the model predicts, we show the disagreement. The forecast isn't gospel; we don't pretend it is. GROUND TRUTH Forecasts lag reality. When the model says cloudy but radar at your spot shows rain—or the nearest weather station is reporting different conditions than the model predicted—we surface a "Ground truth" badge instead of doubling down on the wrong forecast. Tap it to see the disagreement spelled out, including the source we're trusting and why. ANIMATED RADAR + NOWCAST Watch precipitation move in real time. Premium unlocks the next-hour nowcast so you know what's coming before it arrives. PUSH NOTIFICATIONS THAT RESPECT YOUR TIME — A one-sentence weather story, every morning, links to today's full weather story — Severe weather watches and warnings, the moment they're issued — A heads-up before rain begins, with intensity context BUILT FOR WEATHER NERDS — Concept-of-the-day cards spanning core meteorology, named systems, planetary atmospheres, and climate science — Learn factoids that surface real atmospheric facts — Honest framing about model resolution ("rain in the area," not "rain at your house") — Ground-truth badge when live observations disagree with the forecast model PREMIUM Unlock all forecast sources, all map layers (wind, heat), the next-hour radar nowcast, 10 day forecast (from 7), and unlimited Sky responses. Monthly and annual subscriptions available. If you've ever wondered what's actually going on up there—not just what to wear today—Why Weather is built for you.
