The planner shows data as they come directly from the models.
TAF is written down by a meteorologist.
Meteorologists can add value to the model data.
A human forecaster has knowledge of the local topography, as well as historical knowledge
of how the land affects the wind, the visibility, cloud bases etc in an area,
and can therefore predict the weather with accuracy.
For flight decisions, is better to rely on TAFs.
Thank you. Depending on the model, I can see similar differences between MOS and TAF forecasts. Switching models in Windy, I can also see differences.
