  1. Initial Forecast

    Model forecasts 50% delay risk for Atlanta departures 6–9 PM Saturday

    Tailodds’ model gives the 180 departures scheduled from Atlanta 6–9 PM Saturday an average 50% chance of leaving 15+ minutes late. With calm weather the same flights would average 27%. From the 7:00 AM EST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  2. Escalation Forecast

    Updated model puts Atlanta departure delay risk 6–9 PM Saturday at 59%

    What changed: 50% → 59% since the 7:00 AM EST forecast (model changed)

    Tailodds’ model gives the 181 departures scheduled from Atlanta 6–9 PM Saturday an average 59% chance of leaving 15+ minutes late. With calm weather the same flights would average 27%. From the 8:00 AM EST forecast (model famB-sd-v4i). The model changed since the previous item (from famA-fc-v3+famB-sd-v4i), so some or all of this change comes from the new model rather than new information. This is a forecast, not a report of delays.
