Read the freezing level before the snowfall total. Here, northwest flow off the Sea of Japan is the pattern to watch, so the useful question is how cold and calm the next window stays. With a 220 to 390 metre elevation band and 170 metres of vertical, the sheltered trees make modest reloads feel deeper than the raw number. A seasonal baseline around 15 metres means the headline numbers can be real storm signals rather than background noise. The swing variable is whether the snow line stays below the 220 metre base through the storm. Use the access rules on the day as the limit, then let the wind and temperature decide how far to push it. Chase it when 15 to 25 cm lands cold to the base; skip it when the forecast shows a warm lower mountain.
