Lead Times > 24 Hrs; Prob. Guidance 10 Days
Prototype profiler snow-level product showed 2700 ft snow level at the coast, 1300 ft lower than the snow level that had been predicted before landfall.
NWS’ Portland OR SOO (Bill Schneider) upgraded earlier Snow Advisory to a Winter Storm Warning based on this lower snow level and passes being at 4000 ft.
Forecaster’s use of these data increased warning lead time by 15 h in this case and increased POD by avoiding a miss.
