Allentown saw temperatures soar into the 90's for the third day in a row on Wednesday, officially making this stretch the second heat wave of the summer in the Lehigh Valley. Overnight, expect warm and sticky conditions under partly cloudy skies with temperatures falling into the mid 60's.
It looks like the heat wave will continue into Thursday, as temperatures are expected to reach the low 90's again with continued humidity. Skies will feature both sunshine and clouds, but as we reach the afternoon, a spotty P.M. shower or thunderstorm isn't out of the question, especially in the Poconos. As we head towards Thursday evening, one or two stray showers or storms could spread south and east, so there will be some shower activity in spots. Lows on Thursday will reach the mid 60's with otherwise partly cloudy and humid conditions.
Friday starts off dry, and the majority of the day will be dry, but as this frontal boundary approaches, we will still see a shower or thunderstorm in spots. It looks like there will be relief from the heat though, as temperatures fall back into the low 80's, but it will still be rather humid.
Right now, Labor Day Weekend is looking like a winner, with skies staying mostly to partly sunny and temperatures in the mid to upper 80's for Saturday, Sunday and Monday.
