  3. Resolution Forecast

    Model lowers expected cancellations among Tampa departures 3–6 PM Sunday to about 3

    What changed: about 4 → 3

    Adding up each flight’s cancellation probability, Tailodds’ model expects about 3 of the 50 departures scheduled 3–6 PM Sunday to be cancelled (6%). With calm weather it would expect about 0. From the 10:00 AM EST 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.
