If you climb this weekend in the catskills bring your balls and leave your long screws at home.
Think november conditions. No snow, thin ice, and thinner topouts. What looks good from the road looks thin from the base, and thinner at the topouts.
That's not to say things can't be climbed, they just can't be protected unless things change from last night to the weekend (which is entirely possible). Your best bet would be to give everything a week to build and enjoy the long weekend next weekend. If it stays cold conditions will improve quickly with the snow coming sunday.
If you do head out, please be kind to the ice.
