@Suty Yet you superimposed a precipitation type layer on the radar,which is obviously not real time?
The other day, out of idle curiosity, I checked a bunch of webcams at locations where Windy radar claimed it was snowing. Cams at higher altitude indeed showed snow, everywhere else it was raining. Rain, not sleet. So not only is the overlay not real time, it's not very accurate either (based on anecdotal observations, I know).
I'm very pleased to learn that this snowflake overlay will be made optional. The sooner the better. Thank you for listening to your users.
