      The NOAA today announced a major upgrade to the GFS model: https://www.noaa.gov/media-release/noaa-upgrades-us-global-weather-forecast-model

      The model now includes "a new dynamical core called the Finite-Volume Cubed-Sphere (FV3)." The NOAA believes this will result in a dramatic increase in accuracy, bringing the model's accuracy in line with or above that of other top models.

      Does the GFS forecast in Windy already reflect the upgrades to GFS?

      Thanks!

        As far as I'm aware the GFS in windy is stuck on 06z. So I would say no windy isn't reflecting the FV3 upgrade. Maybe someone @windy can provide some more info?
