Forecast Significant Developing Escalation Cancellation LAS departures

Updated model now expects about 10 among Las Vegas departures noon–3 PM Sunday

What changed: about 6 → 10 expected cancellations since the 1:00 AM PST forecast

Adding up each flight’s cancellation probability, Tailodds’ model expects about 10 of the 109 departures scheduled noon–3 PM Sunday to be cancelled (9%). With calm weather it would expect about 1. From the 6:00 AM PST 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.
