@idefix37 Nowcasting rain based on radar data is something I really miss and while Windy is the most comprehensive weather app I know of, lack of this feature forces me (and some users I know) to use other apps on the side just for this purpose.
You are saying this model / data is not available. I am not sure what other apps are doing (and I mean 3rd party apps, not necessarily official apps of national weather services) that it is possible for them but it is still problematic for Windy. I would guess (and feel free to correct me), that while this data is available, it is restricted to specific locations and/or there is a cost for using them.
Couln't Windy consider consuming and presenting such data as other apps do? They could be provided only for Premium users, or some possible higher Premium tier (if cost is the thing which currently prevents it). Local area limitation of such nowcasting could be somehow indicated in the UI to avoid confusion (if the problem is of not having the data globally).
