Check the weather. If they're blowing snow, you NEED goggles and waterproof clothing. It can get frigid especially once the sun goes down. Pennsylvania weather is all over the place so the best advice is to wear layers that you can shed if you get too warm. Don't underestimate the cold.
Usually not super cold, I usually wear a north face layer and a sweatshirt for sunny/cloudy days. A lot of people wear show pants and snow jacket. Anything you wear will be fine
