It would be a reasonable tool to allow LoS assessment of different times of day, based on the predicted weather condition, i.e. the commander should be able to estimate the LoS of the next morning form the previous night, based on the weather report, especially if he can determine LoS down to 100 square meters, and vice versa.
A step further would be to allow LoS assessment for different weathers as well, e.g. estimate the LoS of clear weather when the predicted weather pattern is fog.
