Yup, this weekend looks cold enough up north to keep it icy and firm. Today may have been the worst day of the season with the solidly below freezing temps after rain and warmth. The top snow layer has melted back to the glacial base (still very deep, but it's packed ice essentially) and there isn't much groomers can do with that when its 15-25F.
This weekend with more rain coming Friday and then colder weather Saturday/Sunday that won't break freezing in the Northern Greens will lead to some real rugged skiing.
We are at the point where the temperature needs to be above freezing for it to be worth skiing, unless it snows, which doesn't look likely anytime soon.
