Escalation Forecast
Updated model puts Sacramento departure delay risk 9 PM–midnight Sunday at 64%
What changed: 48% → 64% since the 9:00 AM PST forecast (model changed)
Tailodds’ model gives the 15 departures scheduled from Sacramento 9 PM–midnight Sunday an average 64% chance of leaving 15+ minutes late. With calm weather the same flights would average 32%. From the 10:00 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 delays.
