Now that you've limited the data access for users, did you take into consideration to give premium access to the members feeding their PWS data to Windy?
I'm thinking about something like flightradar24, flightaware & co are doing. To reward their feeders sharing the ADS-B feed, they upgrade those members to business/enterprise tiers.
One good use for that would be a temperature outlook, because now I could use the arrow keys to view temperature on different days but on the same selected time. Whereas currently it's more useful if you want to see temperature in upcoming hours, not days. That's because it's hard to see the big picture because of temperature varying too much..
