  1. Initial Forecast

    Model forecasts 41% delay risk for Raleigh/Durham departures 3–6 PM Friday

    Tailodds’ model gives the 54 departures scheduled from Raleigh/Durham 3–6 PM Friday an average 41% chance of leaving 15+ minutes late. With calm weather the same flights would average 24%. From the 4:00 PM EST forecast (model famA-fc-v3). This is a forecast, not a report of delays.

  2. Escalation Forecast

    Updated model puts Raleigh/Durham departure delay risk 3–6 PM Friday at 54%

    What changed: 41% → 54% since the 4:00 PM EST forecast (model changed)

    Tailodds’ model gives the 63 departures scheduled from Raleigh/Durham 3–6 PM Friday an average 54% chance of leaving 15+ minutes late. With calm weather the same flights would average 28%. From the 11:00 AM 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.
