Initial Forecast
Model forecasts 41% delay risk for JFK departures noon–3 PM Friday
Tailodds’ model gives the 67 departures scheduled from JFK noon–3 PM Friday an average 41% chance of leaving 15+ minutes late. With calm weather the same flights would average 18%. From the 1:00 PM EST forecast (model famA-fc-v3). This is a forecast, not a report of delays.

Escalation Forecast
Updated model puts JFK departure delay risk noon–3 PM Friday at 66%
What changed: 41% → 66% since the 1:00 PM EST forecast (model changed)
Tailodds’ model gives the 77 departures scheduled from JFK noon–3 PM Friday an average 66% chance of leaving 15+ minutes late. With calm weather the same flights would average 18%. From the 7:00 AM EST forecast (model famB-sd-v4i). The model changed since the previous item (from famA-fc-v3), 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.
