Forecast Confidence Screensaver
The Forecast Confidence screensaver shows every member of a weather ensemble drawn at once. Where the members agree the band is tight and the forecast is trustworthy; where they fan apart, nobody actually knows yet. It's free, runs in your browser, and ESC exits.

- Why are there so many lines?
- Each is one member of the ensemble — the same model run from slightly different starting conditions. Where they agree the forecast is solid; where they fan apart it genuinely isn't known.
