I can't speak for the map builders, but I suspect the key here is that the waters in this map area are generally shallow, and would be frozen for most of the winter, and they've left it at that.
I agree it would certainly be nice to be able to choose unfrozen water for scenarios where snow has fallen but the water has not yet frozen, but I don't believe you have that option here.
I think as a mission builder your best option is to research when the Azov Sea froze in 1941 (some time in November I suspect). Then any mission before that use the Autumn map.
