We experienced moderate snowfall throughout the morning hours, around S1. Snow in the morning at all elevations had changed to rain below 3000ft by the early afternoon.
We were mostly in sheltered terrain. So we mainly saw light winds, but plenty of soft snow is still available to blow around.
At about 4000ft, we found an HS of around 215cm and a generally right-side-up snowpack. The interface buried today consists of a thin, fragile melt-freeze crust with buried surface hoar below today's storm snow (5cm and counting). This week's storm snow rests on a melt-freeze crust and shows a favorable bond to this interface down about 40cm. The notable crusts in the snowpack are down 40cm, 145cm, and 170cm. We think these are the 1/12, MLK, and Christmas Crust, respectively, although it's quite different than other areas closer to Snoqualmie Pass proper.
It was a stormy day with temperatures hovering around freezing, steeper slopes were actively rollerballing, and pinwheels were prevalent. We observed no other signs of instability.
