Changing from Air Heavy/Rain with Ground Heavy/Light Mud to Air Cold converts into either Ground Light Snow or Ground Clear. Afaik all Mud disappears (the water levels stay but have no effects).Sertorius21 wrote: Sun Dec 21, 2025 2:37 pm Further questions as we are now in April 1943 and the weather was heavy rain + heavy mud across most of the map, with water levels at mostly 8 or 9. This shifts to cold. Do I read correctly the manual by assuming that this will translate into another turn of heavy mud? The reasoning is that the water level will change between -1 and +2, but not being higher than 6. Given that the starting points are 8 or more, all that part of the map should be at 6. Let me know if there is a doubt about this as I will not spend the same amount of time or have the same frontline with heavy mud or clear ground (even light mud may be useful for the vily Russian).
I think the manual is missing a:
"Cold makes all Water Levels be ignored" remark for the Air Cold weather.
So from how far I can tell you can calculate with either Ground Clear or Ground Light Snow. Think this are all possible Ground Weathers after Heavy Rain+Mud(any) possible in your case.
