Monday afternoon update
It's finally here. The first turns of the 2017-18 ski season will be made this week! Snow guns will be firing up tonight across New England. Looking at who is already in play, expect Killington to be making their first passholder-only turns by the end of the work week, with other early season players coming on board by the end of the weekend. Sunday River has already announced a weekend opening, and Bretton Woods may join in. Exciting! Let's break it down day by day.
Snow guns will be running in the early morning hours at elevation. Lower areas will hold off. Most areas will have to temporarily shut down during the day as temperatures climb into the 30s. Northern New England should be able to keep the guns on at elevation at places like Sugarloaf, Wildcat, and Stowe.
Just about at dusk expect the snow guns to go online. Temperatures and humidity will be a prime for a early November window. At night snowmaking should be able to go all the way to the base.
A lot like Tuesday. Guns go off during the day and come back on in the evening hours. For now temperatures look good to go for more top-to-bottom snowmaking that night, though will be warmer than Tuesday night and a shift of a couple degrees makes a huge difference. While not ideal at low elevations, it is a workable window.
Guns go off at daybreak. It looks like conditions may not be favorable to a return to snowmaking until after midnight A short wave trough will be swinging through the area. If the current model solutions play out, look for two weak low pressure systems to pass to either side of us: one across central Quebec and another out to sea.
With New England between two lows, expect us to be in a trough where winds turn out of the south and humidity rises. The result for us will be marginal at best snowmaking at best.
After the trough passes through New England, expect temperatures to drop to stay below freezing all day. Sub-freezing temperatures should extend all the way to the coast. Expect anyone and everyone who wants to make snow to do so. Near record cold temperatures mean an excellent stretch of production.
Snowmaking continues all day Saturday. By now you should be skiing.
Winds turn out of the south on Sunday, and temperatures rise above freezing by mid-day. The next system moves through late Sunday into Monday. It's too early for details, and rain vs snow remains to be seen. We'll keep an eye on it and let you know more as the time approaches.
