  1. Initial Forecast

    Model forecasts 44% delay risk for SFO departures 6–9 PM Thursday

    Tailodds’ model gives the 79 departures scheduled from SFO 6–9 PM Thursday an average 44% chance of leaving 15+ minutes late. With calm weather the same flights would average 29%. From the 8:00 AM PST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  2. Resolution Forecast

    Model lowers SFO departure delay risk 6–9 PM Thursday to 37%, near normal

    What changed: 44% → 37%; calm-weather level 34%

    Tailodds’ model gives the 80 departures scheduled from SFO 6–9 PM Thursday an average 37% chance of leaving 15+ minutes late. With calm weather the same flights would average 34%. From the 1:00 PM PST 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.
