As an area of low pressure tracks from the Lower Mississippi Valley towards the Mid Atlantic coast later on Sunday, light precipitation will become likely for at least the southern half of Pennsylvania. With temps in the upper 30s to low 40s, precipitation will likely start out as rain or a mix Sunday afternoon, before transitioning to mostly snow after sunset Sunday evening. Snow tapers off later Sun night. While snow amounts are still uncertain, much of central PA will see less than 1 inch of accumulation. The highest chance for over 1 inch of snow is across eastern PA.
