A cold front sinking south over the past couple of days stalled over southern Pennsylvania and has now begun moving back north through Pennsylvania as a warm front. This will allow hot humid air to remain over the area for the first half of the weekend, with temperatures again approaching record levels. Given this hot and moist airmass, thunderstorms may pop up in the region this afternoon but there doesn’t appear to be much of a forcing mechanism so we will keep any storms to a mention. A cold front approaching from the west will arrive late Saturday night, as it approaches so will the chances for showers and thunderstorms across the area. While these thunderstorms will likely be severe well to the west in Ohio and far western Pennsylvania and West Virginia, they will weaken as the night progresses before arriving in the region.

Showers will continue east out of the area Sunday morning as the front continues through. It will be breezy as cooler and drier air is quickly ushered in behind the front, with temperatures topping out in the mid 80s and dew points falling through the 50s in the afternoon. Sunday night will have an early fall like feel as lows drop into the low 60s.
