  1. Initial Forecast

    Model forecasts 66% delay risk for Phoenix departures 6–9 PM Sunday

    Tailodds’ model gives the 168 departures scheduled from Phoenix 6–9 PM Sunday an average 66% chance of leaving 15+ minutes late. With calm weather the same flights would average 42%. From the 8:00 PM MST forecast (model famA-fc-v3). This is a forecast, not a report of delays.

  2. Escalation Forecast

    Updated model puts Phoenix departure delay risk 6–9 PM Sunday at 76%

    What changed: 66% → 76% since the 8:00 PM MST forecast (model changed)

    Tailodds’ model gives the 167 departures scheduled from Phoenix 6–9 PM Sunday an average 76% chance of leaving 15+ minutes late. With calm weather the same flights would average 54%. From the 12:00 PM MST forecast (model famB-sd-v4i). The model changed since the previous item (from famA-fc-v3), 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.
