Escalation Forecast
Updated model now expects about 11 among JFK departures 3–6 PM Sunday
What changed: about 7 → 11 expected cancellations since the 4:00 AM EST forecast
Adding up each flight’s cancellation probability, Tailodds’ model expects about 11 of the 97 departures scheduled 3–6 PM Sunday to be cancelled (11%). With calm weather it would expect about 1. From the 5:00 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.
