After three days of bright sun and temperatures in the 50s, a cold front has cooled things off. A dusting to maybe an inch of new snow fell, although isolated pockets may have picked up more. However, ski conditions will be very fast and icy, so a hike with good traction aids is probably the best choice for an activity this weekend.
There is still a good base at the groomed x-c centers, and those are a really the only possibility for skiing this weekend. Mt. Van Hoevenberg, Cascade, and Paul Smiths all have complete cover, but grooming will take time, so don't expect everything to be skiable first thing Saturday morning.
It will remain cold through Monday (highs only around 20), but will warm to the 40s by the middle of the week. Some additional snow possible on Sunday night, but not likely enough to improve the skiing.
Trail Conditions 101
Trail condition reports are posted frequently during the ski season. The Adirondack backcountry can be a hard place to predict with weather and trail conditions that often change rapidly. We can't offer the same detailed descriptions of trail conditions as groomed nordic centers.
