  1. Initial Forecast

    Model forecasts 61% delay risk for Newark departures 6–9 PM Saturday

    Tailodds’ model gives the 91 departures scheduled from Newark 6–9 PM Saturday an average 61% chance of leaving 15+ minutes late. With calm weather the same flights would average 36%. From the 7:00 AM EST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  2. Escalation Forecast

    Updated model puts Newark departure delay risk 6–9 PM Saturday at 63%

    What changed: 61% → 63% since the 7:00 AM EST forecast (model changed)

    Tailodds’ model gives the 92 departures scheduled from Newark 6–9 PM Saturday an average 63% chance of leaving 15+ minutes late. With calm weather the same flights would average 36%. From the 8:00 AM EST 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.
