We’re heading into the final weeks of skiing season but limping into them might be a better term for much of New Hampshire, where resorts will try to stay open through the end of the month.

Last weekend’s warm rain obliterated the snowpack south of the White Mountains and damaged it further north, putting a damper on what has been an excellent winter for snow sports. With temperatures and humidity forecast to be too high for making snow to patch bare and icy spots, conditions will be erratic at best.

Until that point, this winter has been the best for years despite a relatively late arrival of big snowstorms. Importantly, New England wasn’t hit with warm rainstorms mid-winter, which allowed the snowpack to build up. For example on Mt. Mansfield in Vermont, where daily snow depth has been measured since 1954, the snowpack at the start of March was over 100 inches deep, roughly 2 ½ feet higher than average on that date.

As of this writing, Crotched Mountain, King Pine and Tenney Mountain plan to close this Sunday while Pats Peak and Dartmouth Skiway will close the following Sunday, March 30.

A number of resorts including Mount Sunapee, Ragged Mountain and Cannon Mountain have said they’ll stay open until the weekend of April 6, with Loon and Waterville Valley targeting the weekend after that.

Ski areas in Maine are on similar schedules but Vermont received more snow than the rest of New England this year and virtually all of its ski areas are projected to stay open longer. Jay Peak, which at one point this winter had received more snow that most ski areas out West, and Killington are looking to have operations continue through mid-May.

Some resorts may close on slow weekdays to preserve what they’ve got for the final weekends; Wachusett in Massachusetts did that earlier this week.
