By mid-August, New Jersey transitioned to more pleasant, seasonable weather with temperatures in the 80s and manageable humidity. However, a weather shift was anticipated for the following Sunday, as a storm system threatened to bring 1 to 2 inches of rainfall and thunderstorms. A Coastal Flood Advisory was issued for the Delaware Bay, with potential tidal flooding in Salem, Cumberland, and Cape May counties, while a low risk of rip currents remained for the Jersey Shore.

Following this period, New Jersey experienced unsettled summer weather characterized by periods of rain and thunderstorms. After a wet weekend, Monday saw rain with the potential for localized ponding or flooding in areas where the ground was already saturated. While subsequent days offered sunny and warm conditions with highs in the 80s, a frontal boundary was expected to stall over the region later in the week, potentially bringing renewed rain chances from Thursday through Saturday.
