| Area Forecast Discussion National Weather Service Mount Holly NJ 141am EDT Tuesday September 8 2026 .WHAT HAS CHANGED... .KEY MESSAGES... 1. High pressure will result in tranquil conditions through Wednesday. 2. A cold front will cross the area Thursday bringing the potential for a round of showers and storms. KEY MESSAGE 1...High pressure will result in tranquil conditions through Wednesday. Broad high pressure over the Great Lakes and Northeast slides towards the Mid-Atlantic later today, then will be offshore tonight. A cold front approaches from the west on Wednesday. Mostly sunny and mild today with highs in the low to mid 80s with low humidity. Clouds increase somewhat tonight, and with a light southerly flow, lows will be a bit warmer tonight. Southerly pressure gradient tightens on Wednesday as that cold front approaches from the west. A bit warmer and more humid on Wednesday with highs in the mid 80s or so and surface dew points rising into the low to mid 60s. Showers and thunderstorms will stay to the north and west during the day. KEY MESSAGE 2...A cold front will cross the area Thursday bringing the potential for a round of showers and storms. Mid-level ridging will begin to break down on Wednesday across the region as an upper-low traverses portions of the Hudson Bay into Quebec. On Thursday, a more pronounced shortwave will pass through the region. At the surface, a cold front will pass through the region Thursday. Scattered showers and storms could begin moving into northwestern portions of the area as early as overnight Wednesday night as the front begins to approach. Probability of Precipitation through Thursday morning are currently 20-40% and confined to the Lehigh Valley, Poconos, and adjacent areas of far northern NJ. On Thursday as the front makes its way southeastward through the area, scattered showers and storms will likely accompany it. Despite somewhat impressive kinematics, most model guidance features modest destabilization at best ahead of the front, with MLCAPE generally around 500 J/kg to 1000 J/kg. Discrepancies do remain with respect to timing of the frontal passage and associated shower and storm chances. A slower front progression through the region could allow for a bit more destabilization than is currently anticipated. All of this being said, the threat for severe storms currently appears fairly low, but not zero. Any potential hydro concerns look limited by the progressive nature of the front and storms. Behind the front, a drier and somewhat cooler airmass looks to settle into the region for Friday. The forecast beyond Friday is a bit more uncertain as some guidance hints that the frontal boundary may stall somewhere to the south of the region with a few waves of low pressure riding along it. This will need to be monitored as it could lead to somewhat unsettled conditions for the weekend. Marine Sub-Small Craft Advisory conditions today through tonight. West to northwest winds less than 10 kt, becoming south to southwest 10 to 15 kt this afternoon and tonight. Seas around 2 feet. Outlook... Wednesday through Thursday...SCA (Small Craft Advisory) conditions probable. South- southwest winds of 15-20 kt with gusts 25-30 kt likely beginning Wednesday afternoon and continuing through Wednesday night into part of the day Thursday before diminishing. Seas 4-6 feet. Thursday night through Saturday...No marine headlines currently anticipated with winds below 25 kt and seas below 5 feet. Rip Currents... For Tuesday, northwest winds 5-10 mph in the morning will turn south to southwesterly in the afternoon. Breaking waves will be around 1 to 2 feet. Light northeasterly swell around 9 seconds in length. Given these factors, have opted to maintain the LOW risk for the development of dangerous rip currents for all shore points. For Wednesday, south to southwest winds of 5-10 mph in the morning will increase to 10-20 mph in the afternoon. Breaking waves of 1-2 feet in the morning will increase to 2-3 feet in the afternoon. Light easterly swell around 10 seconds in length. For now, have opted for a LOW risk for the development of dangerous rip currents for all shore points. If winds trend in a more shore-normal direction, at least some shore points could warrant an upgrade to MODERATE risk in future forecast updates.
