I realize that the lack of snow along the highways in Montana may not correlate to low snowpack in the mountains but I recently looked at about 30 Montana DOT webcams from around the state.
There is virtually no snow
We have it all here in the Northeast.
I don't know how this compares to other winters in Montana and the Park could still see appreciable snowfall in April and May. However, the overall lack of snow in the West this winter could mean earlier trail openings and increased forest fire danger this summer.
