  2. Escalation Forecast

    Updated model now expects about 25 among O'Hare departures 6–9 AM Saturday

    What changed: about 22 → 25 expected cancellations since the 8:00 PM CST forecast

    Adding up each flight’s cancellation probability, Tailodds’ model expects about 25 of the 231 departures scheduled 6–9 AM Saturday to be cancelled (11%). With calm weather it would expect about 1. From the 9:00 PM CST forecast (model famB-sd-v4i).
