The freezing level for today will slowly rise to 1200 meters by tonight. Strong winds and moderate to heavy precipitation for most of the day with a trailing cold front sometime tonight. The freezing level has the potential to reach 2500 meters as the Pineapple Express arrives onshore. Whistler might get lucky with the FL maxing out at around 1500 meters on Friday. Fingers crossed. A cold front moves onshore for Friday with more of the same. Possible break Saturday morning with a series of weaker frontal bands into early next week. Guesstimates: 25-35 cm by Friday morning, 30-50 cm by Saturday morning above 1500 meters, 10-15 cm by Sunday morning.
