| Area Forecast Discussion National Weather Service Mount Holly NJ 208pm EDT Monday Jun 15 2026 .WHAT HAS CHANGED... Updated Aviation section for 18Z TAFs. .KEY MESSAGES... 1. Another round of minor coastal flooding is expected with this evening's high tide cycle along the Atlantic coast and Delaware Bay. 2. Some severe thunderstorms possible Thursday afternoon and evening. KEY MESSAGE 1...Another round of minor coastal flooding is expected with this evening's high tide cycle along the Atlantic coast and Delaware Bay. Minor tidal flooding occurred once again this past evening in association with the New Moon that just occurred Sunday. As we remain near the New Moon, at least one more cycle of widespread minor coastal flooding is expected with the Monday evening high tide cycle along the Atlantic coast and the Delaware Bay. New Coastal Flood Advisories have been issued as a result. There may also continue be some back bay flooding even this morning around Barnegat Bay so we've ran the Coastal Flood Advisory for Ocean County starting this morning and going right to 2am Tuesday. Beyond tonight, tides will continue remain at least somewhat elevated heading into midweek but will generally trend lower with each cycle. KEY MESSAGE 2...Some severe thunderstorms possible Thursday afternoon and evening. An upper-level trough centered over south-central Canada is forecast to strengthen eastward and also southward across the Great Lakes to end the week. A strong shortwave rounding the base of this trough may result in a portion of it taking on a negative tilt across the eastern Great Lakes and toward New England late Wednesday and Thursday. This feature is a bit stronger in the ECMWF (European Centre for Medium-Range Weather Forecasts) solution, while the GFS (Global Forecast System) ensembles are mostly a little weaker. A deepening surface low will accompany it and track across the eastern Great Lakes and into adjacent Canada during Thursday. A strong cold front will then arrive into our area Thursday afternoon or Thursday evening. As the synoptic pattern evolves, the flow will increase out of the south and southwest. This will advect deeper moisture northward, and in tandem with strengthening warm air advection will lead to increased instability during the day Thursday. In addition, a strong mid to upper level jet is forecast to extend eastward from the eastern Great Lakes. While the core of the 500 mb jet (80-100 knots) is forecast to remain mainly northwest of our area, 40-70 knots of flow at 500 mb is still forecast across our area Thursday afternoon into the evening. This increased flow will result in greater shear magnitudes. While there remains some timing differences among the guidance regarding the main features, the consensus is that enough instability should overlap with the stronger shear along with incoming stronger forcing. As a result, there continues to be some severe thunderstorm potential Thursday afternoon and evening. As of now, locally damaging winds are the primary threat especially if convection develops into a squall line. However if shear and instability ends up being even greater, than all severe thunderstorm hazards may come into play especially if the mode is discrete for a time. The details remain much less certain at this time range given the typical uncertainty with instability and the thermodynamic profiles. The forecast synoptic setup however with a deepening surface low tracking to our northwest with strong flow within a warmer and more moist environment suggests some risk for severe thunderstorms. In addition, the main trough may end up arriving on Friday with some additional chances for showers and some thunderstorms. The I-95 corridor and the coastal plain (away from the immediate coast) looks to be the hottest during Thursday ahead of the convection, with the heat indices potentially getting very close to 100 degrees. Marine No marine headlines are in effect through Tuesday. Northwest winds around 10-15 kt, gusting up to 20 kt through Tuesday morning. Winds will then become southwesterly by mid-day around 5-10 kt, increasing late in the afternoon between 10-20 kt. Seas generally around 2-3 feet. Fair weather through Tuesday. Outlook... Tuesday night through Wednesday...The conditions are anticipated to be below Small Craft Advisory criteria. Thursday...A period of Small Craft Advisory conditions probable. Southerly wind gusts could near gale force for a time later Thursday. Some gusty thunderstorms late in the afternoon and evening possible. Friday...The conditions are anticipated to be below Small Craft Advisory criteria. Rip Currents... For Today, winds become northwest 10-20 mph with a continued medium southerly swell of 6-7 seconds. With breaking waves 2 feet or less, have gone with a LOW risk for the development of dangerous rip currents at all beaches. For Tuesday, winds start northerly before shifting southeasterly, but only at around 5 mph with a continued medium southerly swell of 6-7 seconds. With breaking waves 2 feet or less, have gone with a LOW risk for the development of dangerous rip currents at all beaches.
