  1. Initial Forecast

    Model forecasts 50% delay risk for Las Vegas departures noon–3 PM Saturday

    Tailodds’ model gives the 90 departures scheduled from Las Vegas noon–3 PM Saturday an average 50% chance of leaving 15+ minutes late. With calm weather the same flights would average 23%. From the 2:00 AM PDT forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  2. Resolution Forecast

    Model lowers Las Vegas departure delay risk noon–3 PM Saturday to 30%, near normal

    What changed: 50% → 30%; calm-weather level 23%

    Tailodds’ model gives the 90 departures scheduled from Las Vegas noon–3 PM Saturday an average 30% chance of leaving 15+ minutes late. With calm weather the same flights would average 23%. From the 4:00 AM PDT 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.
