  1. Initial Forecast

    Model forecasts 41% delay risk for Austin departures noon–3 PM Saturday

    Tailodds’ model gives the 56 departures scheduled from Austin noon–3 PM Saturday an average 41% chance of leaving 15+ minutes late. With calm weather the same flights would average 21%. From the 1:00 AM CST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  3. De-escalation Forecast

    Updated model puts Austin departure delay risk noon–3 PM Saturday at 41%

    What changed: 55% → 41% since the 2:00 AM CST forecast (model changed)

    Tailodds’ model gives the 56 departures scheduled from Austin noon–3 PM Saturday an average 41% chance of leaving 15+ minutes late. With calm weather the same flights would average 21%. From the 3:00 AM 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.
