Missing: Large hail forecast
-
One forecast item that would be very important to persons in the mid- USA and elsewhere would be a hail forecast, especially large hail. It is on the rise as an increasingly , dangerous and costly weather parameter to personnel and corporations, like insurers and farmers.

I'm not sure the current weather models shown in Windy are able of predicting hail.
You can view Weather warnings for your area and the radar layer. There is a risk of hail when the signal exceeds 50 dBz.
And see Weather warnings

Or you can go to weather warnings layer directly: https://www.windy.com/-Weather-warnings-capAlerts?capAlerts,38.908,-94.702,5

@Filip_K The warnings alone don't really give a good picture of what areas are at imminent risk. (For instance, the map warnings are by county, but here in Texas, counties are often large enough that the NWS warns only portions of a county, e.g., Southwestern X County.)
I'd suggest a new map for localized projected near future (no more than an hour, probably) severe weather: Hail/Tornadoes/Severe T-storms.
I'm no meteorologist, but it seems like nearly all the data required to drive a pretty good hail/tornado/high winds risk map is already in the system (you could probably do a decent first cut at this by just summing data from some of these layers and visualizing that, then playing with weights to tweak): Storm severity and coverage from Radar and Satellite, CAPE, Cloud Tops, Lightning, Icing, Winds at various altitudes, and Freezing Altitude. (The altitude-based ones may require some computation and flattening first.)
I realize this is a non-trivial integration, and I'd be fine if it's a Premium-only feature. (And it might help drive some subscription revenue for y'all as well.) I've been glued to Windy and a couple of other products continually recently to decide whether or not we have to move cars under cover - Ranchers have the same problem with their livestock. You want to know the risk so you only go to the considerable trouble to get everything protected if you're pretty likely to get whacked.
(Other, related thoughts: Actual storm tracks (and maybe fronts?) could be an input to this, too (if you add those), especially if they're not just the simplistic linear ones from most Doppler radar products, which often show confusing overlaps of paths in turbulent storm conditions. Does anything in Windy's analysis code look for hook signatures from tornadoes in radar? (Maybe not, since it's not obvious you have a Doppler radar source...) Precip Rates could be useful for this, too (as well as Flash Flood risk visualization), but I'm not sure you have that as readily available in your data as the metrics above...)
Thanks to the Windy Team for a truly amazing product!

Существует риск града, когда уровень сигнала превышает 50 дБз.
Надо создать слой с риском града -
@dub 🟩 A green Cumulonimbus is full of ice/hail.
The apps visualize precalculated super-computer-model-data, not always lucky.
Real-time layers are just radar & satellite, hopefully the warnings.
Reading the clouds is my favorite approach, from downside or above...https://community.windy.com/topic/33079/all-forecast-data-wrong/4

I would also imagine that it is possible to combine data/layers to have a 'Hail layer' created in-house by the Windy devs.
[Temperature - Rain - Icing - Freezing altitude - CAPRE index - etc]
You can see in the forums for years that users have been requesting it.
User would understand that it'll be trial and error at first BUT if Windy can nail this layer and it works well, I can guarantee you'll have a flood of users wanting to use the layer. Make it a premium feature too if need be.
