Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Warm and stable air. Slight westerly breeze, mid 50's at sea level. Mid to high 40's on Seattle ridge at 6pm. High clouds beginning to stream in as we left.

Snow surface

Isothermal at 1K. Becoming supportable around 2K. Thin degrading sun crust on all aspects but North. Still some hot pow on North. Overall, really fun, quality spring snow to be had!


No pit info but direct sun and warming temps definitely adding to instability later in the day. Powder cloud in May??!! Still dry snow to be found up high!
