An exception is across the eastern 1/3 of the state, where onshore flow will bring in low clouds and patchy mist overnight. Nighttime temperatures remain mild for this time of year, with lows ranging from the lower 50s across the Northern Tier, to the upper 50s across the Pittsburgh and Philadelphia metros. Unseasonably warm temperatures are expected once again on Saturday as southerly winds continue to draw mild air over the region ahead of a cold front. A band of showers and thunderstorms associated with this front will develop across western Pennsylvania in the afternoon, with locally strong to severe storms being possible. The primary risk will be damaging winds, with potential impacts including downed trees and power lines. These storms will weaken into rain showers after sunset as the front moves across central and eastern PA. Much cooler conditions are expected in the wake of this front, with frost/freeze potential Monday & Tuesday mornings. Drier postfrontal weather is expected except for a few lake-effect and upslope rain/snow showers over the Allegheny Plateau. A return to milder temperatures is expected mid-week. $$
