Snowpack
I went hunting for unstable snow (away from the road!) and found a more settled and stronger upper snowpack following more melting and last night's hard freeze. I dug on a 25 deg, SW facing slope, sheltered from wind, at 1:30pm. The top 50 cm of snow refroze last night and was pencil hard except for the upper 20 cm which had already become saturated due to today's heating (Teton Pass temp showed 37F at the time but with most snow dirty and soaking up the sun). Below the pencil hard rounds was fist hardness moist rounds- yesterdays moist mush which had not refrozen overnight. An extended column test propagated on that boundary at 23 taps...stubborn for sure due to the strength of the refrozen snow. Tomorrow temperatures are forecast to be a 3-5 degrees warmer in the heat of the day but models are currently showing about 10F warmer tonight than last night. The warmer temperatures will lead to speed up the destabilizing effects of water in the snowpack, again. Not as bad as the recent record warmth, but I expect a bump in the danger tomorrow, especially at mid-elevations, if temperatures overnight stay in the upper 20s and daytime temps reach their forecasted high in the mid-40's. I think wet slabs will be unlikely but higher sun angles, warmer temperatures and a not-entirely-isothermal snowpack raise some questions.
