| Area Forecast Discussion National Weather Service Mount Holly NJ 215pm EDT Monday September 29 2025 Synopsis High pressure is in control through Tuesday. A strong but moisture-starved cold front moves through on Tuesday night before an expansive area of high pressure moves in for the rest of the week and the upcoming weekend. Near Term - Through Tuesday Very large shield of high clouds has spread north of Imelda, but otherwise, impacts for land areas are expected to be minimal before it turns east and out-to-sea on Tuesday. Otherwise, weak high pressure will remain in control through Tuesday, keeping it warm and humid by late September standards. A few showers may creep their way into parts of the Delmarva, most likely this evening, but overall dry weather should prevail with a relatively light northeast wind of 5-10 mph. Near the coastal waters, this wind may become closer to 10-20 mph by later in the day Tuesday. Lows tonight will be in the mid 50s to mid 60s, warmest south/coast/urban areas, while highs Tuesday will be in the mid 70s to low 80s, warmest eastern PA and central/northern NJ where there should be a little more sun and a bit less marine influence. Short Term - Tuesday Night Through Thursday Initially, a fairly complex upper-pattern will be in place across the region as we find ourselves between a ridge to the west over the Missouri Valley and Great Lakes regions, Humberto and Imelda to the southeast over the open Atlantic, and the polar jet across portions of northern New England. With time, the ridge will expand eastward, eventually encompassing our area on Thursday, as the other features continue to track away. At the surface, a cold front will track southward through the region Tuesday night, with strong high pressure building in from the north. With sufficient moisture in place and easterly flow, widespread cloud cover is expected Tuesday night ahead of the cold front. No precipitation is expected, however, and clouds should clear from north to south with the frontal passage. Lows Tuesday night look to be in the mid-upper 40s across the higher elevations of eastern PA and far northern NJ, the low 50s across the remainder of eastern PA and inland NJ, and in the upper 50s to near 60 along the coast and in the Delmarva. Wednesday should feature mostly clear skies with highs ranging from the upper 60s to low 70s. Wednesday night will feel like fall, with temperatures falling deep into the 40s across eastern PA and northern NJ, and the upper 40s to near 50 elsewhere. The cooler trend will continue on Thursday, with highs likely struggling to climb out of the 60s across the entire area. Aside from fair weather and cooler temperatures behind a cold front, our area will be between the pair of tropical cyclones to our southeast and strong high pressure building in from the north. This setup will favor gusty winds along the coastal strip. The gustiest period looks to be Tuesday night into Wednesday, with gusts in the 30-40 mph range. As of right now, it appears winds will fall short of wind advisory criteria, but this is something that will need to be watched the next few forecast cycles in case there is any upward trend to forecasted winds. Long Term - Thursday Night Through Sunday There will likely be very little change to the upper-pattern through the extended period, with ridging remaining situated over the eastern tier of the US. At the surface, high pressure will remain centered over portions of the Mid-Atlantic and northeast. Tranquil weather is expected from Thursday night through Monday, with skies ranging from partly to mostly clear. Temperatures will remain below average Thursday night through Friday night, though slowly moderating with time. By Saturday, temperatures are expected to be mostly seasonable across the area. Sunday into Monday look to continue the slow moderating trend, with temperatures getting back to being slightly above normal. Marine Small Craft Advisory goes into effect this evening on the ocean waters as seas start to build thanks to the influence of Hurricane Humberto and Tropical Storm Imelda. While the SCA continues as seas build further on Tuesday, winds should stay below advisory levels through Tuesday. However, they will start increasing notably towards day's end. Outlook... Tuesday night through Wednesday...Confidence is increasing in a period of gale force winds beginning Tuesday night and continuing through much of the day Wednesday. Have issued a Gale Warning for ocean zones south of Manasquan Inlet, where frequent gusts of 35-40 kt are expected. Have maintained the SCA north of Manasquan Inlet and for the Delaware Bay, where winds are expected to peak in the 25- 30 kt range. Seas over the open ocean could build to 7-11 feet. Wednesday night through Thursday...SCA (Small Craft Advisory) conditions are expected to continue across all ocean zones, and at least the lower Delaware Bay. While winds should decrease on Thursday, seas will remain elevated, in the 5-7 foot range. Thursday night...SCA (Small Craft Advisory) conditions may linger on some waters, primarily in the form of elevated seas. Friday through Saturday...No marine headlines expected. Fair weather. Rip Currents... For today, the increasing influence of longer period swells around 13 to 16 seconds combined with there being multiple swell groups along with northeast winds around 10 to 15 mph will result in a MODERATE risk for the development of dangerous rip currents at all beaches. Generally expect wave heigheights in the surf zone to be around 2-3 feet. For Tuesday, the long period swells associated with the tropical systems to our south will continue to build and this will result in a HIGH risk for the threat of dangerous rip currents at all beaches. Generally expect rough surf conditions as wave heigheights in the surf zone look to be around 3 to 6 feet. Increasing onshore winds of 10-20+ MPH are expected. Issued a Rip Current Statement for Tuesday. For specific beach forecasts, visit weather.gov/beach/phi The SRF product and rip current discussion will end on September 30th.
