Area Forecast Discussion National Weather Service Mount Holly NJ 316am EDT Thu August 14 2025 Synopsis A cold front approaches today and moves across the region tonight. The front then gets hung up over the Mid-Atlantic through the weekend as high pressure builds over the Northeast and into eastern Canada. A cold front crosses the region late Sunday into Monday. High pressure returns for the middle of next week. Near Term - Through Tonight Patchy fog and low clouds will be around the area early today with lingering moisture from last nigheights rains. Conditions will improve after sunrise with light Southwest to West winds developing. Scattered showers will be possible across southern NJ and Delmarva between 8AM and Noon. The airmass hasn't changed very much since yesterday. Drier air is to the NW across southern Canada and a weak front across wrn NY/warning PA delineates the front edge of this drier air. The front will weaken as it crosses the area today. As it pass thru, more upper shortwaves arrive. These factors will result in more showers/thunderstorms for the region today. The showers will likely develop earlier than on Wednesday. The high PW values (Precipitable Water values) will lead to more downpours for the area. The Day1 outlook from Storm Prediction Center just has general thunderstorms for our area today. For tonight, the scattered shower/tstm activity will decrease after sunset and skies will become partly cloudy overnight. High pressure to the north will edge into the southern Poconos and North NJ. Drier air associated with the high will slowly spread southward tonight. There is still the possibility of local fog overnight with the Short Term - Friday Through Saturday Night The cold front that passed through the region will settle over the Mid-Atlantic region. Meanwhile, high pressure over eastern Canada builds down into the Canadian Maritimes and Northeast. This results in an onshore flow over the area. While temperatures will not be overly warm, generally topping off in the mid 80s or so, cooler along the coasts, the onshore flow will result in high surface dew points over the area. Max heat index values will top off in the low to mid 90s. Zonal flow aloft sets up, and some shortwave energy approaching from the west will interact with the aformentioned stationary front south of the area. Scattered showers and thunderstorms will develop in the afternoon and evening, mainly over southern and western portions of the forecast area. High pressure over the Northeast slides to the south, and winds shift to more of a westerly flow. Drier air, though still a bit humid, filters into the region as dew points drop into the upper 60s to around 70 on Saturday. Temperatures will once again be in the 80s. Some weak shortwave energy may spark off a few afternoon showers and thunderstorms, but coverage will be isolated. Cooler Saturday night. Long Term - Sunday Through Wednesday Warm and humid on Sunday as return flow increases ahead of an approaching cold front. That cold front crosses the region late Sunday and Sunday night. Highs will be in the 80s to around 90, and surface dew points will be up around 70, resulting in max heat index values in the mid 90s or so. Though scattered showers and thunderstorms will develop in the afternoon and evening, there does not look to be much upper level support, as the base of an upper trough remains well north of the area, and shortwave energy does not look to be strong. Will follow NBM and carry 20 to 40 percent PoPs. It looks to be a bit cooler and a bit less humid on Monday, but a secondary cold front will pass through the region in the afternoon. Once again, some afternoon showers and thunderstorms will be possible, but Probability of Precipitation are fairly low at 20 to 30 percent. That front becomes nearly stationary over the Mid-Atlantic. Several shortwaves approach from the west and may keep conditions unsettled for the middle of next week despite high pressure building in from the northeast. Highs will be in the low 80s with dew points int he 60s. Will follow NBM Probability of Precipitation and carry 20 to 30 percent chances for showers and thunderstorms. Marine Winds and seas remain below SCA (Small Craft Advisory) levels today and tonight. Scattered showers/thunderstorms are expected to develop (again) today. There will be locally higher wind and seas with any tstm. Light S/SW winds early today then N/NE winds late today and tonight. Outlook... Friday through Monday Sub-SCA (Small Craft Advisory) conditions through the period. Rip currents... Southwest winds this morning will become light and variable before becoming southeast 5 to 10 mph this afternoon. Breaking waves will be 1 to 2 feet. There will be light easterly swells with a 7 to 8 second period. As a result, there is a LOW risk for the development of dangerous and life threatening rip currents at the Jersey Shore and at Delaware Beaches today. For Friday, winds will be out of the northeast, turning east in the afternoon, at 5 to 10 mph with breaking waves of 1 to 2 feet. The period will be around 8 seconds. As a result, there is a LOW risk for the development of dangerous and life threatening rip currents at the Jersey Shore and at Delaware Beaches for Friday.
