On my system…the AM CC system, the winter months wreak havoc on the MW band here. More noise and buzz saw junk, especially at night. The upper part of the band becomes saturated with stations. Fortunately 1670 still remains fairly clear overnight to continue operating. However the distance down the lines does get affected. This is probably caused by the moisture and/or ice and snow buildup on those lines, particularly the neutral, thus creating a rather large attenuator along the entire length of the line the signal travels on, which in my station’s case is the neutral line, which is not insulated.
I do find that the emergency 3 meter setup works beautifully in the winter months. This is probably due to the already good ground conductivity here, my proximity to a river that flows through town, and add the rain/snow moisture factor into the whole mix, that creates a nice and very large ground “blanket” and that tiny 100mW stick kicks that signal out a good 2-3 miles. In the summer, it hits just under 1 mile on a dry day.
