A mix of sun and clouds will prevail this afternoon, with just isolated snow flurries across the mountains. The next system will likely arrive Saturday afternoon as a low pressure center tracks just south of Pennsylvania, bringing chances for additional snowfall across the region. Much colder air will surge into the region from the 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 and upslope snow across the portions of northern and western Pennsylvania. Lows tonight and Saturday night will be mainly in the teens. Highs on Saturday will range from the upper 20s and 30s across the west, to the lower 40s in the far southeast. Highs on Sunday will range from the teens across the north and west, to the mid 20s across the southeast. $$ Martin
