Escalation Forecast
Updated model puts Philadelphia departure delay risk 6–9 PM Saturday at 56%
What changed: 44% → 56% since the 7:00 AM EST forecast (model changed)
Tailodds’ model gives the 65 departures scheduled from Philadelphia 6–9 PM Saturday an average 56% chance of leaving 15+ minutes late. With calm weather the same flights would average 26%. From the 11:00 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 delays.
