| Area Forecast Discussion National Weather Service Mount Holly NJ 143pm EST Tuesday Nov 25 2025 Synopsis A low pressure system is approaching from the west today bringing rain to the area into tonight. The low will cross north of the area while its associated cold front will pass across region Wednesday into Wednesday night. A high pressure system will then build in to end the week and for the start of the weekend. Near Term - Through Wednesday Broad low pressure lies over the Great Lakes while a weak secondary low lies over the Tennessee Valleys. Both systems will lift to the northeast tonight, pushing a warm front north through the region. Broad low pressure will lie over the northern Great Lakes as that secondary low will track over eastern Pennsylvania and New Jersey this evening. Another weak area of low pressure will lift through the region Wednesday morning as a stronger warm front lifts north through the region. A cold front then approaches Wednesday afternoon. In terms of sensible weather, rain develops late this afternoon and becomes more steady and persistent into this evening with that first low and warm front. Around midnight or so, rain tapers off, and then it will be warm and muggy for the overnight hours with fog and low stratus. A second round of showers will impact the area in the pre-dawn hours into Wednesday morning as that second warm front with weak low pressure lifts north through the region. There should be enough elevated instability across Delmarva and southeast New Jersey as ML MUCAPE values will be up to 300 J/kg along with 0-6 km of Bulk Shear to allow a few rumbles of thunder. Low clouds and patchy fog will persist through the morning and into early Wednesday afternoon. There should be enough breaks in the clouds in the afternoon to allow for some sunshine to develop. As that cold front approaches Wednesday afternoon, some showers and possible thunderstorms may move into far western portions of the forecast area. Lows tonight will generally be in the mid to upper 40s north and west of the I-95 corridor and in the low to mid 50s south and east of a line from Philadelphia to Wilmington. Lows will be in the upper 50s in southern Delmarva. Highs on Wednesday will be quite mild, generally in the mid to upper 60s. Rainfall amounts will range from around 1/2 inch to 3/4 inch. Short Term - Wednesday Night Through Friday A cold front passes through the area Wednesday night and we see strong cold air advection with winds also increasing out of the west. Wind gusts will start to increase to 30-35 mph across the area with upwards of 40 mph in the Poconos. Lows Wednesday night will be in the upper 20s to mid 30s. Wind chill values will be in the 20s and potentially the teens in the Poconos. A few showers may linger early across our eastern zones Wednesday night as the cold front continues to clear the area. Winds continue to increase for Thursday and Friday with cold air continuing to filter in. For Thanksgiving, the day looks dry but cold and windy. Highs are in the mid 30s to mid 40s. Gusty winds out of the west at 30-40 mph. Lows Thursday night are in the 20s. Wind chills will be in the teens when you factor in the windy conditions. Friday looks to be the windiest day with gusts out of the west- northwest at 35-45 mph. In this set-up, with all the cold air filtering in across the region, there will be ongoing lake-effect snow showers upstream of our area. Due to the wind shift to have a more NW component, we have the potential to see some snow showers in the Poconos and northern NJ on Friday. Highs on Friday are in the mid 30s to mid 40s. Long Term - Friday Night Through Monday Our winds do start to decrease Friday night as a surface high builds in and moves overhead into Saturday. This will keep us dry Friday night into Saturday. For the weekend, it is a colder start with highs on Saturday in the mid 30s to low 40s. By Sunday, temperatures start to climb back into the upper 40s to upper 50s for highs. On Monday, highs reach into the 40s for most. There is also the signal for another system to bring increasing precipitation chances on Sunday into Monday. Marine Small Craft Advisory conditions develop on the ocean waters tonight. South winds 10 to 15 kt with gusts up to 20 kt through this evening, then winds increase to 15 to 20 kt with gusts up to 25 kt. Though there may be a lull in 25 kt gusts Wednesday morning, winds ramp back up in the afternoon. Will keep the SCA (Small Craft Advisory) in effect. Winds on Delaware Bay will be a bit lower, hence no SCA (Small Craft Advisory) for those waters for tonight through Wednesday. Seas 2 to 3 ft, building to 3 to 5 ft Wednesday afternoon. Visibility restrictions in rain and fog tonight through late Wednesday morning. A few thunderstorms are possible on the southern ocean waters late tonight through Wednesday morning. Outlook...
