A weak trough in a Northwest flow aloft will slowly push through today with periods of light precipitation and a rising freezing level. The freezing level could rise to 1500  meters but will likely hover in the 1200 meter range. Low pressure moving down the coast will bring more active weather for Saturday into Monday before a possible drying trend on Wednesday into the weekend. Difficult to pinpoint the exact amount of precipitation for Saturday but looks like steady light/moderate precipitation and strong winds. The cold front & arctic front associated with the upper level low may move in fairly quickly on Saturday night with a decent amount of snow and the freezing level rising to nearly 1500 meters. If the FL stays around 1200 meters and jet flows over the area we might get more snow than some models are forecasting. Time will tell. Winter is back over the weekend and the avalanche danger will change. WB likely will close up hill routes with the storm bringing the hazard rating to at least considerable. Guesstimates: 5-10 mm by Saturday morning, 20-30 mm by Sunday morning, 15-20 mm by Monday morning.

    Fronts along the coast.

      Low will send a vigorous cold front our way for Saturday.
