  1. Initial Forecast

    Model forecasts 73% delay risk for BWI departures 9 PM–midnight Friday

    Tailodds’ model gives the 58 departures scheduled from BWI 9 PM–midnight Friday an average 73% chance of leaving 15+ minutes late. With calm weather the same flights would average 53%. From the 10:00 AM EST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  2. Resolution Forecast

    Model lowers BWI departure delay risk 9 PM–midnight Friday to 61%, near normal

    What changed: 73% → 61%; calm-weather level 54%

    Tailodds’ model gives the 58 departures scheduled from BWI 9 PM–midnight Friday an average 61% chance of leaving 15+ minutes late. With calm weather the same flights would average 54%. From the 11:00 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.
