Windy does not create any forecast data but instead only visualises forecast and actual data received from various third party providers.

In addition, it is important to choose the weather model that gives the best temperature forecasts in your area. In Canada, Windy offers 4 weather models.
Selecting Reported temperature you can compare the observed temperature vs forecasts of each model. It seems that Meteoblue gives the best results near Notre-Dame-du-Nord.

The other models are worse. They show a wider gap between the observed temperature curve and the forecast temperature one.
