Of course, the snow line will have its "ups and downs" . In our area, being located more-or-less on the shores of the Pacific Ocean, weather patterns often bring a surge of warm and moist air from as far away as Hawaii, or even the South Pacific - which usually means rain. So this line is likely to move up and down in the coming weeks. Of course, as spring approaches, the line will "ascend" in a similar manner.
Well, regardless of what is heralded, it's just "plain beautiful" (is this an oxymoron?)
