    Humidity will soon build around Philadelphia and allow drenching thunderstorms to return at midweek.

    Those with outdoor plans and projects should take advantage of the dry stretch of weather Monday through Tuesday. High pressure will be overhead during that time but will slowly depart.

    A noticeable increase in humidity will occur on Tuesday, setting the stage for spotty afternoon thunderstorms to erupt toward Harrisburg. Thunderstorms should hold off for one more day around Philadelphia.

    Wednesday is when the combination of the sticky air and a storm system moving in from the Midwest will bring numerous thunderstorms to the Philadelphia area.

    The most active time of Wednesday is likely to be the afternoon when some of the thunderstorms will unleash blinding and flooding downpours.

    Commuters may be faced with a slow ride home, while flight delays are possible. The storminess could also interfere with the Phillies game between the Miami Marlins at Citizens Bank Park Wednesday evening.

    As long as the storm system creating Wednesday's storminess is not slower to depart, a dry Thursday should unfold before the thunderstorm chance quickly returns for Friday.

    High temperatures will start this week in the lower 80s before rising to the upper 80s toward the weekend. Average highs for the end of June are in the middle 80s.
