Tomer’s Take: A new Pacific pattern engages 1/19-1/28 with warmer air temps, higher snow levels, heavy West Coast/PNW precipitation, and a couple southern track storm systems. The next wave of snow hits the Wasatch, Tetons and mountains of Colorado 1/20-1/22 with light to moderate snow accumulation. CA gets moderate to heavy snow above 7500′ late 1/19-1/22.
