Problem #1 Comments
Wet avalanches, glide avalanches, cornices, and roof slides are the clear threat in the coming days (again). Photo below of cornices overhanging Scott Hill with little wet activity to show.

Increasing Danger
Problem #2 Comments
Forecast free air temperatures at 700mb (~10,000') +6C Thurs and +10C Friday night after today's +1C would imply "rapid warming" over the next several days with perhaps wet avalanches becoming more prevalent, even on polar aspects. That said, the storm snow from last week seems to have fairly well transitioned with sun/temps. Wind, cloud cover, RH, etc will be other factors to consider in the coming days.
Dust layers are always interesting to hydrologists and avalanche practitioners. Chris Landry (Painter, Deems, et al) in Silverton/mid-2000s with the Center for Snow and Avalanche Studies and more recently U of U professor McKenzie Skiles have a number of papers investigating dust on snow events in Colorado and Utah, respectively.
