An isolated shower is possible for most of the overnight with a steadier rain developing closer to daybreak (especially in areas located south and east of the Lehigh Valley). Overnight lows will only fall into the mid 60s and with dew point mirroring or just slightly below the air temperatures it's going to be fairly humid. Saturday will start out with the aforementioned steadier rain south and east and some showers and thunderstorms for the rest of us. However, aside from a stray shower here and there much of the afternoon and evening on Saturday more clouds than sunshine with a shower or two and a thunderstorm (mainly in the afternoon). Aside from the rain you can expect humid conditions with highs near 80 degrees for the second half of the weekend.
