  2. Resolution Forecast

    Model lowers Boston departure delay risk 9 PM–midnight Thursday to 33%, near normal

    What changed: 40% → 33%; calm-weather level 26%

    Tailodds’ model gives the 32 departures scheduled from Boston 9 PM–midnight Thursday an average 33% chance of leaving 15+ minutes late. With calm weather the same flights would average 26%. From the 7:00 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.
