High pressure will make a brief cameo on Wednesday, holding colder air in place across the state under partly to mostly cloudy skies. This colder air will then play a crucial role with the wintry mix that will overspread the state midday Thursday. In general, look for the precipitation to be majority snow north, and majority sleet south, with some freezing rain mixing in in spots. Skies remain mostly cloudy Friday as precipitation clears the area by the afternoon. Despite weak high pressure building in Saturday, clouds will dominate with a few lake-effect showers possible in extreme northwestern Pennsylvania. An upper-level disturbance dives south late in the day Sunday, bringing with it a quick hit of rain and snow, with frozen precip more likely in the northwest half of the Commonwealth.
