Read the freezing level before the snowfall total. The headline number only helps once you know whether northwest flow off the Sea of Japan is the pattern to watch. With a 122 to 532 metre elevation band and 410 metres of vertical, the gladed pockets are the first place to check once the groomers get tracked. A seasonal baseline around 8 metres means small clean refills matter more than waiting for a giant number. The swing variable is whether the snow line stays below the 122 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.
