@TZ "the data is valid for the previous day - it is not real-time". Hmm ...that's interesting to note and keep in mind TZ, so may I humbly suggest a kinda floating window indicating these limitations with, maybe, a time stamp about when the data has been processed?
What Windy.com is very good at is that in a single place one can find almost every environmental data he wishes to find. So when a rather strong limitation such as this one rises, it is my opinion that it should be, somehow, somewhere, clearly stated.
This is just to keep the big wheel turning, keep up the good work!
