Another weather system will likely arrive Saturday afternoon as a low pressure center tracks just south of Pennsylvania, bringing chances for additional snowfall to the Commonwealth. Mainly clear skies are expected early tonight before clouds arrive from west to east ahead of the aforementioned low pressure system. Downwind of Lake Erie, it will remain cloudy overnight with isolated snow flurries. Much colder air will surge into the region on gusty winds 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 portions of northern and western Pennsylvania. Low temperatures 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. $$
