Read the freezing level before the snowfall total. Here, Sea of Japan storm flow is the pattern to watch, so the useful question is how cold and calm the next window stays. With a 200 to 1020 metre elevation band and 820 metres of vertical, the upper half can ski like a different day from the lower half. A seasonal baseline around 10 metres means moderate-looking totals can still refresh the main lines quickly. The swing variable is whether the snow line stays below the 200 metre base through the storm. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase it when 10 to 20 cm lands cold to the base; skip it when the forecast shows a warm lower mountain.
