@Korina here in the middle of the US, I tend to rely on GFS, but I am often startled by how different the 3 US National Weather Service models (GFS, NAM, HRRR) are.

RE: ICON precipitation units
@idefix37 this was in Richmond, Indiana USA (which is not Richmond, Virginia). The forecast was at 21:30 EDT on Tuesday, April 20, 2021.
I've had this issue before, though. A conjecture based on, oh, nothing: there was snow earlier in the forecast. Perhaps once the display starts showing cm for snow, it just keeps showing cm, even if later precipitation events are rain? I can't remember if I've seen the problem in reverse, with several cm of snow being reported as a few mm of rain.

ICON precipitation units
In Windy 28.1.1 both on Android 10 and on my Mac, ICON seems to be reporting precipitation using the units for snow, even if rain is predicted. The attached screenshot https://photos.app.goo.gl/Ydz18itLkJEHNGWr7 shows the issue. The other models are predicting 10-20mm of rain. ICON is predicting 30cm of snow. This can't be its real prediction with a temperature of 10C, so I'm assuming the issue is one of units.
The problem doesn't seem to exist in the meteogram display. -
RE: New/Old subscriptions
@Korina Thanks. I guess I didn't read the announcement carefully enough. Well, if all I can do is contribute less than I used to, then I guess that's how it is. Windy is wonderful, in any case!
One of my uses for Windy is to see in advance which coming storms are just rain, and which have lightning. I'm a member of an equestrian co-op at the college where I teach. The horses can stay in the fields when it rains, but we need to get them back to the barn during thunderstorms. We used to wait until we heard thunder to rush out to the pastures, endangering both the horses and ourselves if we were too slow. Now we can see which coming storms have lightning, and we can move before it gets dangerous and frightening for the animals. So Windy isn't just for pilots. It's also for people with 4-legged ground transportation. Not your original usage model, but thank you!

New/Old subscriptions
I have been supporting Windy with a $4.99 monthly subscription on android for a number of months. I don't remember if that gets me anything except good karma.
How does that connect to Windy Premium? I don't seem to be able to access the 1 hour forecasts right now. Getting Premium by dropping the $4.99 subscription and adding a $2.99 subscription feels like a bad way to show my support. Do I need both? Is there a way to get Premium while maintaining the karmic benefits of paying you more than 2.99/month?
