  1. Initial Forecast

    Model expects about 10 cancellations among Salt Lake City departures 9 PM–midnight Saturday

    Adding up each flight’s cancellation probability, Tailodds’ model expects about 10 of the 34 departures scheduled 9 PM–midnight Saturday to be cancelled (30%). With calm weather it would expect about 0. From the 10:00 AM MST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of cancellations.

  2. Resolution Forecast

    Model lowers expected cancellations among Salt Lake City departures 9 PM–midnight Saturday to about 3

    What changed: about 10 → 3

    Adding up each flight’s cancellation probability, Tailodds’ model expects about 3 of the 34 departures scheduled 9 PM–midnight Saturday to be cancelled (9%). With calm weather it would expect about 0. From the 11:00 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 cancellations.
