Read the freezing level before the snowfall total. When west to northwest flow off the Sea of Japan is the pattern to watch, the live numbers usually matter most in the first lift window. With a 440 to 760 metre elevation band and 320 metres of vertical, the gladed pockets are the first place to check once the groomers get tracked. A seasonal baseline around 9 metres means small clean refills matter more than waiting for a giant number. The swing variable is whether the snow line stays below the 440 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.
