  2. Resolution Forecast

    Model lowers Midway departure delay risk 6–9 PM Wednesday to 38%, near normal

    What changed: 46% → 38%; calm-weather level 30%

    Tailodds’ model gives the 53 departures scheduled from Midway 6–9 PM Wednesday an average 38% chance of leaving 15+ minutes late. With calm weather the same flights would average 30%. From the 8:00 AM CST 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.
