Hi everyone,
I’ve noticed something strange when using Windy with the MeteoBlue model. I understand that the model is updated every 12 hours. For example, this morning after the update, the forecast for today showed a high of 66°F at 2pm.
However, a couple of hours later, the forecast data changed again – and now it looks like MeteoBlue had already predicted the real Temperaturen of 70°F earlier, even though that wasn’t shown right after the update. In the “Forecast vs Observed” comparison, it now seems as if the model got it right from the beginning.
Why does this happen? Why aren’t the most accurate predictions shown immediately after the model update, but only appear retroactively as if they were always there?
Thanks in advance for any clarification!
