  1. Initial Forecast

    Model forecasts 40% delay risk for Las Vegas departures 9 AM–noon Saturday

    Tailodds’ model gives the 96 departures scheduled from Las Vegas 9 AM–noon Saturday an average 40% chance of leaving 15+ minutes late. With calm weather the same flights would average 19%. From the 10:00 PM PST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  2. Escalation Forecast

    Updated model puts Las Vegas departure delay risk 9 AM–noon Saturday at 51%

    What changed: 40% → 51% since the 10:00 PM PST forecast (model changed)

    Tailodds’ model gives the 97 departures scheduled from Las Vegas 9 AM–noon Saturday an average 51% chance of leaving 15+ minutes late. With calm weather the same flights would average 19%. From the 11:00 PM 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.
