772 FXUS61 KPHI 290536 AFDPHI Area Forecast Discussion National Weather Service Mount Holly NJ 136 AM EDT Sat Aug 29 2026 .WHAT HAS CHANGED... Updated the aviation section for 06Z TAFs. && .KEY MESSAGES... 1. High pressure builds in tonight through Saturday bringing clearing skies with cooler and less humid conditions. 2. Increasing heat and humidity return next week with unsettled weather. && .DISCUSSION... KEY MESSAGE 1...High pressure builds in tonight through Saturday bringing clearing skies with cooler and less humid conditions. A cold front still located near the coast will move south of the area before dawn. Behind the cold front, it looks drier into at least tomorrow. A high pressure system builds in for Saturday keeping the area dry. An upper-level disturbance moving through the region on Sunday has the potential to result in some showers and thunderstorms, particularly during the afternoon and evening hours. KEY MESSAGE 2...Increasing heat and humidity return next week with unsettled weather. Broad upper level ridging returns to the eastern US early next week, bringing in surface high pressure across the eastern US. Afternoon highs will creep back into the upper 80s to low 90s, about 5 degrees above average for early September. Dew points will also creep back into the low 70s. One other aspect to watch with this ridging pattern is the potential for thunderstorms to rotate around the periphery of the ridge and the position of a warm front next week. The exact location, timing, and intensity of the thunderstorms remains a bit uncertain at this range. Currently, the main days to monitor are Tuesday and Wednesday regarding heavy rain and severe weather potential. && .AVIATION /06Z SATURDAY THROUGH WEDNESDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Through 12Z...VFR. NNE winds 5-10 kts. High confidence. Saturday...VFR. North to northeast winds around 5 kts, becoming light and variable after 18Z. Sea, bay, and river breezes should then favor south to southeast winds around 5 kts for PHL and south. High confidence. Saturday night...Prevailing VFR, though some patch fog is possible. Winds light and variable to calm. Low confidence on fog potential. Outlook... Sunday through Wednesday...Restrictions possible in showers and thunderstorms each day, mainly during the afternoon to evening hours. && .MARINE... Northerly winds may briefly gust to around 25 knots overnight tonight but this should only be for a period of an hour or two at most. Otherwise, no marine hazards expected. Outlook... Saturday night and through Wednesday...No prevailing marine hazards expected. Chances for thunderstorms each day, mainly in the afternoon and evening hours. Rip Currents... For Saturday, NNE winds of 10-15 mph decrease to around 5 to 10 mph while turning E to ENE in the afternoon. There is a 1 to 2 foot east-southeasterly swell with a period of 7-8 seconds. As a result, there is a MODERATE risk for the development of dangerous and life threatening rip currents at the Jersey Shore and a LOW risk at Delaware Beaches. On Sunday, S to SSW winds of 5-10 mph increase to 10-15 mph in the afternoon. A 1 foot southeasterly swell with a period of 7-8 seconds lingers. As a result, there is a LOW risk for the development of dangerous and life threatening rip currents at the Jersey Shore and Delaware Beaches.
