  1. Initial Forecast

    Model forecasts 54% delay risk for Atlanta departures 6–9 PM Sunday

    Tailodds’ model gives the 207 departures scheduled from Atlanta 6–9 PM Sunday an average 54% chance of leaving 15+ minutes late. With calm weather the same flights would average 35%. 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 Sunday at 64%

    What changed: 54% → 64% since the 7:00 AM EST forecast (model changed)

    Tailodds’ model gives the 207 departures scheduled from Atlanta 6–9 PM Sunday an average 64% chance of leaving 15+ minutes late. With calm weather the same flights would average 35%. 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.
