  1. Initial Forecast

    Model forecasts 57% delay risk for Phoenix departures 9 PM–midnight Sunday

    Tailodds’ model gives the 77 departures scheduled from Phoenix 9 PM–midnight Sunday an average 57% chance of leaving 15+ minutes late. With calm weather the same flights would average 38%. From the 10:00 AM MST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  2. Escalation Forecast

    Updated model puts Phoenix departure delay risk 9 PM–midnight Sunday at 67%

    What changed: 57% → 67% since the 10:00 AM MST forecast (model changed)

    Tailodds’ model gives the 77 departures scheduled from Phoenix 9 PM–midnight Sunday an average 67% chance of leaving 15+ minutes late. With calm weather the same flights would average 39%. From the 11:00 AM MST 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.
