The system that brough last night’s rains to Philadelphia has departed, but weak high pressure building in will only slowly reduce the humidity through Friday.
For this weekend’s weather, somewhat stronger high pressure will take hold over the weekend, giving us less humidity, but as you can see from the forecast surface weather map, areas of showers won’t be that far from our south and west over the weekend. So partly cloudy/partly sunny skies are expected at this time with no rain.
