This morning at 11:35 it was warm, +1c (34f) and rainy on top of Tumalo. The mountain was in fog. Winds moderate from the west. The snow surface consisted of a recent rain crust from Tue that had been covered with 2cm (1") of new snow on Wed. Today the surface snow was wet, the rain crust had become soft and edgeable.
In the bowl wind transported snow from Wed was wet and well bonded to the crust just below. Turns in the bowl produced pin wheels and roller balls of wet snow. There was no sign of recent cornice build up or collapse in the bowl, no signs of avalanche. The snowpack below the rain crust was saturated, I saw no signs of instability.
Despite wet conditions, skiing in the bowl was quite good :)
