  1. Initial Forecast

    Model forecasts 67% delay risk for Newark departures 9 PM–midnight Thursday

    Tailodds’ model gives the 37 departures scheduled from Newark 9 PM–midnight Thursday an average 67% chance of leaving 15+ minutes late. With calm weather the same flights would average 32%. From the 9:00 PM EST forecast (model famA-fc-v3). This is a forecast, not a report of delays.

  2. Escalation Forecast

    Updated model puts Newark departure delay risk 9 PM–midnight Thursday at 78%

    What changed: 67% → 78% since the 9:00 PM EST forecast (model changed)

    Tailodds’ model gives the 43 departures scheduled from Newark 9 PM–midnight Thursday an average 78% chance of leaving 15+ minutes late. With calm weather the same flights would average 41%. From the 4:00 PM EST 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.
