Read the freezing level before the snowfall total. The headline number only helps once you know whether west to northwest flow off the Sea of Japan is the pattern to watch. With a 323 to 747 metre elevation band and 424 metres of vertical, the groomers tell the story quickly once the first few laps are done. A seasonal baseline around 7 metres means small clean refills matter more than waiting for a giant number. The swing variable is whether the snow line stays below the 323 metre base through the storm. With patrol boundaries in play, focus on how the inbounds snow will hold through the first half of the day. Chase it when 5 to 15 cm lands cold to the base; skip it when the forecast shows a warm lower mountain.
