  1. Initial Forecast

    Model forecasts 50% delay risk for Austin departures 3–6 PM Sunday

    Tailodds’ model gives the 58 departures scheduled from Austin 3–6 PM Sunday an average 50% chance of leaving 15+ minutes late. With calm weather the same flights would average 34%. From the 4:00 AM CST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  2. Escalation Forecast

    Updated model puts Austin departure delay risk 3–6 PM Sunday at 62%

    What changed: 50% → 62% since the 4:00 AM CST forecast (model changed)

    Tailodds’ model gives the 58 departures scheduled from Austin 3–6 PM Sunday an average 62% chance of leaving 15+ minutes late. With calm weather the same flights would average 39%. From the 2:00 PM CST 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.
