Warm, humid conditions will prevail in southern and central Pennsylvania through Labor Day. However, drenching storms may come calling on a couple of occasions.
High temperatures will be in the 80s each day with nighttime lows in the upper 60s to the lower 70s.
After Wednesday's spotty downpours, much of the time through Saturday morning in Harrisburg, York, Lancaster and other communities will be free of rain. While there is a risk of a pop-up shower, these days should be the best bets for outdoor plans at Hershey Park, Knoebels Groves, Dutch Wonderland, ball games, sightseeing or swimming.

There is a chance of thunderstorms firing up Saturday afternoon and evening.
The weather is destined to turn progressively more unsettled Sunday into Labor Day from the mountains to the I-95 corridor.
While these days will also bring their rain-free intervals, a system approaching from the Canada Prairies will increase the number and intensity of showers and thunderstorms.

The least rainiest spots through most of the day Monday are likely to be right at the Jersey shore and along the Delaware and Maryland beaches.

Folks heading home from their Labor Day or late-summer ventures at the shore and mountains could encounter delays at the airports and on the turnpike and interstate highways Monday afternoon and Monday night.
It will not be until a cool front swings through late Tuesday that humidity levels will be shaved and the risk of showers and thunderstorms will diminish.
