Storm Track Prediction
Not sure if Windy provides storm tracks and predictions, but it would be a great addition.
Windy was born in 2014 by Ivo because of his love for the wind. That's why so many options are available for kiting, paragliding and other wind related activities. I don't think that the goal of the developers was forecasting the weather (storm tracks, etc) it can certainly be used by forecasters because of all the layers available. A Windy Launch video is available on YouTube.
May be this new layer could help you?
