With Monday’s temperature climbing towards 70, you could be excused if you thought spring had arrived. (We’ll even excuse you if you thought spring arrived a couple months ago, given the mild winter D.C. has had.)

Well, winter isn’t over yet. A blast of cold air will begin settling on the region Tuesday, dropping daytime temperatures to the 30’s and nighttime temperatures to the teens.

Although this may be too little, too late for some area resorts, Ski Roundtop, Ski Liberty, and Whitetail have not yet made a firm decision to close for the season and will probably resume snowmaking. All three resorts are currently closed, but snowmaking may allow them to open limited terrain for the weekend. Stay tuned to DCSki for the latest.

Other area resorts, such as West Virginia’s Snowshoe, Maryland’s Wisp, and Pennsylvania’s Hidden Valley, expect to receive some natural snow this week. Snowshoe is still making snow, but Wisp has retired the snowguns for the season, aiming to ride out the season with their remaining healthy base.
