Not only for nordic skiing. In the Alps, for touring and slopes, the conditions are also very volatile. You have these heat waves in the middle of the winter which are making the snowpack very unstable. One day the conditions are good, the day after you are not sure anymore. For touring, you basically need to relearn all the heuristics (especially with respect to the safety of the snow) you developed over the years. This is not comfortable.
