Why Weather

The thinking weather app. Sky, our AI meteorology agent, explains the science behind the forecast—and the uncertainty behind the science. For weather nerds.

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.
