  1. Initial Forecast

    Model forecasts 70% delay risk for LaGuardia departures 6–9 PM Thursday

    Tailodds’ model gives the 101 departures scheduled from LaGuardia 6–9 PM Thursday an average 70% chance of leaving 15+ minutes late. With calm weather the same flights would average 27%. From the 7:00 PM EST forecast (model famA-fc-v3). This is a forecast, not a report of delays.

  2. Escalation Forecast

    Updated model puts LaGuardia departure delay risk 6–9 PM Thursday at 82%

    What changed: 70% → 82% since the 7:00 PM EST forecast (model changed)

    Tailodds’ model gives the 102 departures scheduled from LaGuardia 6–9 PM Thursday an average 82% chance of leaving 15+ minutes late. With calm weather the same flights would average 33%. From the 2:00 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.
