| Area Forecast Discussion National Weather Service Mount Holly NJ 618am EDT Sunday Oct 5 2025 Synopsis High pressure remains in control through Tuesday. A cold front comes through on Wednesday. High pressure returns for the end of the week. Near Term - Through Tonight This morning we see some patchy fog linger before dissipating by the mid morning hours. Our high pressure system shifts slightly offshore today, helping keep a light, but warm S-SW flow across the region. This keeps the tranquil weather pattern going with highs in the upper 70s to mid 80s and a mostly sunny sky. For tonight, we see temperatures mainly in the 50s. Dew points will also be in the 50s, and combined with light winds, will lead to another round of potential patchy fog. Otherwise, it is a mostly clear night as we continue to feel the influence from the high pressure system. Short Term - Monday Through Tuesday No major changes to the forecast. Mainly clear weather with above normal temperatures expected to kick off the week. High pressure slides offshore with southerly return flow setting up. This will result in high temperatures both Monday and Tuesday getting into the upper 70s/low 80s for most areas (low to mid 70s along the coast and over the southern Poconos). Overnight lows Monday night look to mainly range from the mid 50s to around 60. There could also be some patchy fog around overnight Monday night into early Tuesday. Some showers are possible late in the day Tuesday as a frontal system approaches, but the bulk of the rain should hold off until Tuesday Night and Wednesday (more on that below). Long Term - Tuesday Night Through Saturday The above normal temperatures come to an end as we get into the middle and end of the upcoming week. A fast moving shortwave digs through southern Canada/northern US, moving toward the northeastern US. At the surface, low pressure slides to the north with a cold front slowly pushing into our region. This will bring a period of rain late Tuesday into Wednesday. Still some minor differences in timing among the different forecast guidance but at this time most guidance indicating the majority of the rain will be overnight Tuesday night with the cold front crossing the area around sunrise Wednesday. So all in all, high confidence of a mid-week rain event and overall, it should just be a beneficial rain. NBM probability of > 1 inch still hovers around 30-40% over the area. Some models have some elevated instability, so cannot rule out a rumble of thunder, but the severe and flash flooding threat seems very low currently. Once the front clears the area by Wednesday night, it will be seasonably cool for the end of the week. Another expansive area of high pressure builds in, which should result in a dry and tranquil end to the week. Temperatures on Thursday and Friday look to be in the 60s with overnight lows in the 40s and some potential upper 30s in the Poconos and northern NJ. Beyond Friday, the forecast becomes a bit more uncertain. Some guidance has high pressure holding firm through the weekend while some wants to bring a weak system through or to our south. Still about a week out though so we stayed with the NBM which brings most areas about a 20 percent chance of showers Friday night into early Saturday. Marine No marine hazards expected through Sunday night. S to SW winds around 5-10 kts withs seas 2 to 4 feet. Outlook... Monday through Monday Night...No marine headlines expected. Tuesday through Wednesday...Wind gusts on the ocean could get near 25 kt at times, resulting in potential SCA (Small Craft Advisory) conditions. Wednesday Night through Thursday...SCA (Small Craft Advisory) conditions expected with gales possible (20-30%). Northerly wind gusts around 25-30 kt with seas 5 to 7 feet.
