| Area Forecast Discussion National Weather Service Mount Holly NJ 141pm EDT Sat September 5 2026 .WHAT HAS CHANGED... changes to the forecast. .KEY MESSAGES... 1. Mostly dry and comfortable weather is expected for the rest of the weekend. A few showers possible tonight however. 2. Minor tidal flooding is anticipated with Sunday afternoon's high tide, mainly for the Jersey Shore, Delaware Beaches, and Delaware Bay communities. 3. A cold front will pass through on Thursday bringing the potential for another round of showers and storms. KEY MESSAGE 1...Mostly dry and comfortable weather is expected for the rest of the weekend. A few showers possible tonight however. A drier and cooler airmass has arrived across the northern Middle Atlantic region as high pressure to the northwest begins influencing our weather to a greater degree. Low pressure aloft across the the Northern Atlantic continues to bring Northwest flow aloft over our area. A couple embedded short waves in this flow will pass across New England and our coastal waters later today and tonight. The activity will drift further south across Delmarva Sunday morning. We could see some scattered showers as a result. probability of precipitation are generally in the 20% to 35% range, so no significant impacts are expected. KEY MESSAGE 2...Minor tidal flooding is anticipated with Sunday afternoon's high tide, mainly for the Jersey Shore, Delaware Beaches, and Delaware Bay communities. Flow will turn more onshore over the next day or so. This will result in water piling up over consecutive tide cycles, potentially leading to minor tidal flooding across portions of our area on Sunday afternoon. The current forecast has minor tidal flooding from Barnegat Bay on south along the Atlantic Ocean coastline and for areas within Delaware Bay. Advisories may be needed in these spots but will wait to see how things trend over the 12 hours with the forecast. Within the tidal Delaware River, northern NJ coast, and Chesapeake Bay, tidal flooding will be limited to spotty minor or no flooding at all. Tide levels should decrease getting into next week as flow turns more offshore. KEY MESSAGE 3...A cold front will pass through on Thursday bringing the potential for another round of showers and storms. By Tuesday, high pressure will begin to shift offshore welcoming the return of southerly flow, resulting in a period of above-normal temperatures and an increase in humidity levels through mid-week. High pressure looks like it will largely remain in control through Wednesday, before giving way to a cold front that will approach the area on Thursday. This front will be the next opportunity for any showers or thunderstorms around the area. However, moisture with the front could end up being limited so at this point POPs are only around 20-30% or less. Marine Winds and seas are expected to stay below Small Craft Advisory conditions through Sunday. Fair then scattered showers tonight and Sunday morning. Outlook... Sunday night through Tuesday night...No marine headlines expected. Northeast winds may briefly get gusty later on Sunday, but should remain below SCA (Small Craft Advisory) criteria. Seas will generally range around 2-4 feet. Wednesday through Thursday...SCA (Small Craft Advisory) conditions probable due to wind gusts around 25-30 kt with seas around 4-6 feet. Conditions will peak late Wednesday into Wednesday night, before gradually diminishing on Thursday. Rip Currents... For Saturday, northerly winds mainly 5-10 mph with breaking waves in the surf zone less than 2 feet. Therefore, will continue with the LOW risk for the development of dangerous rip currents. For Sunday, winds will be more out of the northeast or east-northeast and increase to 10-15 mph. This will build the seas into the coast, with breaking waves in the surf zone 2-3 feet. We will continue with LOW risk for the development of dangerous rip currents, however if the breaking waves increase some more then the risk could increase to moderate.
