The answer is no, because metar reports don’t say how much snow is on the ground.
However, with unreal you can add and change levels while it is on and showing present metar.
The only issue is when a new metar updates, you would need to be change level again since the weather presets would change to fit new metar.
Tbh I don’t see how any live weather will show snow accumulation after, since they can only go by aviation weather reports. ASOBO does not have LIVE humans looking out their windows making the report s.
