Initial Forecast
Model forecasts 50% delay risk for Phoenix departures 9 PM–midnight Sunday
Tailodds’ model gives the 56 departures scheduled from Phoenix 9 PM–midnight Sunday an average 50% chance of leaving 15+ minutes late. With calm weather the same flights would average 35%. From the 1:00 PM MST forecast (model famB-sd-v4i). This is a forecast, not a report of delays.
