    Model forecasts 63% delay risk for Atlanta departures noon–3 PM Wednesday

    Tailodds’ model gives the 178 departures scheduled from Atlanta noon–3 PM Wednesday an average 63% chance of leaving 15+ minutes late. With calm weather the same flights would average 20%. From the 11:00 AM EST forecast (model famB-sd-v4i). This is a forecast, not a report of delays.
