  1. Initial Forecast

    Model forecasts 41% delay risk for Salt Lake City departures noon–3 PM Sunday

    Tailodds’ model gives the 48 departures scheduled from Salt Lake City noon–3 PM Sunday an average 41% chance of leaving 15+ minutes late. With calm weather the same flights would average 23%. From the 1:00 AM MST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  2. Resolution Forecast

    Model lowers Salt Lake City departure delay risk noon–3 PM Sunday to 32%, near normal

    What changed: 41% → 32%; calm-weather level 24%

    Tailodds’ model gives the 48 departures scheduled from Salt Lake City noon–3 PM Sunday an average 32% chance of leaving 15+ minutes late. With calm weather the same flights would average 24%. From the 2:00 AM MST 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.
