according to weather:
for every snow-cloud you have to discard one wood. for all clouds (rain and snow) you have to check the roof level and the difference has to be paid in 1 wood and 1 food for each missing roof level. in your example you spend the 1 food and 1 wood for the missing level and that's it. but after that in the night phase you have to feed everyone and if no food is left each character who has nothing to eat gets two wound.
