There is work to do to improve the sim on snow and lake ice which is linked to snow dept while this is not real life related. Some areas of the world are very cold but has almost no snow but frozen lakes. See this post : Lake Ice Should Not Be Linked to Snow Depth in North-America - #3 by Guillaume3511
There is a slider for snow dept but it remove liveweather, which is bad, and produce poor results like mentionned in this thread.
Hoping they put energy on this while it is winter now.
