Hi,
Windy is a great, useful and beautiful gift to the community, with no way for us to contribute in return.
So I thought I'd contribute, as a native English language speaker, by making some suggested tweaks to the grammar in the FAQ on "What is the Forecast Model?", to make it read more smoothly.
I've put my suggestions in this Google doc:

Hope this is helpful - and keep up the good work!
Andrew.
