A few light upslope snow flakes will still occur today across the Western Mountains of the state. The next system will likely arrive Saturday afternoon as a low pressure center tracks south of Pennsylvania, bringing chances for additional snowfall across the region. Much colder air will surge into the region from the West-Northwest on a gusty wind for Sunday and Monday, bringing some of the coldest conditions that we've seen so far this season, along with another round of significant lake effect snow likely across the Northwest Mountains of the state later Saturday into Sunday. $$
