| Area Forecast Discussion National Weather Service Mount Holly NJ 111am EDT Wednesday September 16 2026 .WHAT HAS CHANGED... .KEY MESSAGES... 1. Mainly quiet this week with high pressure in control. 2. Somewhat unsettled weather will be possible at times late this week and next weekend as multiple systems move through. However at this point significant impacts due not appear likely. KEY MESSAGE 1...Dry and tranquil weather will persist through at least Thursday with a gradual warming trend. An expansive area of high pressure will remain in control through Thursday resulting in a stretch of nice mid-September days. For tonight, with the surface high lingering near the area it will result in another night of mainly clear skies and light winds leading to good radiational cooling conditions. It won't be quite as cool as last night in most places but generally expecting most areas to get down into the 50s with some upper 40s possible in the Poconos. Wednesday through Thursday will feature a gradual warming trend as high pressure slips off to our south as a weak system moves in north of the region by Thursday. This will result in a SW flow developing with warm air advection. Generally expect highs in the 80s with dew points also creeping up through this period as well. Both days should be largely free of any precipitation though by late day Thursday an approaching cold front from the north could result in a few showers affecting the Lehigh Valley into the southern Poconos. POPs though are only around 20-30 percent. KEY MESSAGE 2...Somewhat unsettled weather will be possible at times late this week and next weekend as multiple systems move through. However at this point significant impacts due not appear likely. A cold front still looks to move southward through the area Thursday night into Friday and this could result in some showers. Guidance had been backing off on precipitation with this but some of our latest guidance is a bit more robust once again with showers moving through. The bottom line though is that with the timing mainly at night and mostly just showers expected (probability for thunder is low) this should not be an impactful system. A couple showers could linger into Friday over our southern zones but otherwise it should be a partly to mostly sunny day with temperatures cooling slightly compared to Thursday in the wake of the front. Looking ahead to the weekend, the aformentioned front looks to eventually move back to the north as a warm front late Saturday into Saturday night. The front may then linger near the area Sunday. As this occurs, moisture looks to surge back northward towards the area ahead of a tough moving through the Great Plains. This will bring increasing chances for showers and perhaps a few storms by late Saturday night and especially on Sunday which looks to be the wetter of the two weekend days. POPs for Sunday range from around 30% south up to 60% north. Medium range guidance shows the unsettled period potentially continuing into early next week with multiple waves of low pressure moving through. Still over 5 days out, so things could change with the forecast and it is a bit early to get into specific impacts. However, there is no real overwhelming signal in both deterministic and ensembles of any major impacts at this time with these systems. Marine Sub-SCA (Small Craft Advisory) conditions through Thursday with winds out of the south/southwest around 5 to 15 kt and seas 2 to 3 feet. Outlook... Thursday Night through Sunday...No marine headlines expected at this time. Rip Currents... Today...Breaking waves in the surf zone of 1-2 feet are forecast with a light southerly wind and a 6-8 second period. These conditions will result in the continuation of a LOW risk for the development of dangerous rip currents at all New Jersey and Delaware Beaches. Thursday...Southerly flow increases some, however similar breaking wave heigheights and wave period are forecast. Therefore, a LOW risk for the development of dangerous rip currents are forecast at all New Jersey and Delaware beaches.
