| Area Forecast Discussion National Weather Service Mount Holly NJ 557pm EST Monday Dec 15 2025 Synopsis Arctic high pressure over the Mid-Atlantic settles over the Southeast states Tuesday through Tuesday night before moving out to sea. A weak front passes through Wednesday evening, then a strong cold front moves through our region Thursday night and Friday. High pressure returns into the weekend, however a weak cold front passes through Sunday night. High pressure once again builds in for Monday. Near Term - Through Tuesday Cloud cover continues to slide across our region in response to some upper level energy passing through. Some mostly light snow is occurring just to our west, as of 550 PM, and this may spill into our western zones early this evening. Increase the Probability of Precipitation some to account for this. Any snow accumulation would be very light. Surface high pressure settles off to our south tonight before gradually shifting off the Southeast coast on Tuesday. Skies will clear out overnight and winds will diminish and become light and variable at times. Another very cold night is expected as much of the area should be able to radiate pretty well, especially with the snow cover. As a result, lows should bottom out in the low to mid teens with single digits in the higher elevations. With light winds, wind chills won't be far off from the actual air temperatures overnight. For Tuesday, with the high slowly sliding off the coast, the region will begin to encounter southwesterly return flow. This should allow temperatures to moderate a bit where highs will mainly be in the 30s (20s in the higher terrain). A sunny sky should prevail in the morning, with an increase in high clouds in the afternoon as another upper level disturbance approaches later in the day. Short Term - Tuesday Night Through Thursday High pressure settles off the Southeast coast Tuesday night, and while return flow sets up, the combination of skies clearing out enough with winds light enough and with lingering snowpack that temperatures should radiate down into the teens and low 20s. Zonal flow sets up on Wednesday and a weak trough approaches from the west. Temperatures begin to moderate somewhat, but will still be below normal levels topping off in the low to mid 40s. High pressure then builds back over the area for Wednesday night and Thursday. Still cold Wednesday night with lows in the 20s, but then highs rebound on Thursday to above normal levels in the upper 40s to low 50s north and west of the Fall Line and in the low to mid 50s across the Delaware Valley, Delmarva, and southern New Jersey. Long Term - Thursday Night Through Monday High pressure moves out to sea Thursday night, and low pressure passing through the Great Lakes will drag a cold front into the region late Thursday night and Friday. Temperatures will be warm enough for this to be a mostly rain event, though with cold air advection on the back side of the system, there may be some rain/snow mix in the southern Poconos and portions of the Lehigh Valley. There are some signals for some moderate to possibly even heavy rainfall over the area with this system. The bulk of the rain, at least at this time, looks to fall between midnight or so Thursday night through Friday afternoon. 13Z NBM probability of 24 hour precipitation ending 7 pm Friday is 70 to 80 percent for greater than 0.5 inches and 40 to 60 percent for greater than 1 inch. Lows Thursday night will be in the upper 30s to low 40s, and then highs on Friday will be in the upper 40s to low 50s. This rainfall should take care of the bulk of the snowpack over the area. Cold front passes through by Friday night and then Arctic high pressure builds back into the region with lows in the 20s Friday night and then highs in the upper 30s to low 40s on Saturday. Some strong shortwaves will pass through the region with minimal impacts. High pressure slides offshore Saturday night and temperatures rebound on Sunday with highs in the mid to upper 40s. A weak front may pass through the region Sunday night and then high pressure returns on Monday with near to slightly below normal levels. Marine No marine headlines are expected through Tuesday. West winds will settle out of the west-southwest 15-20 kt tonight with seas of 2-4 feet. For Tuesday, west-northwest winds around 10-15 kt and seas of 1-3 feet are expected. Fair weather. Outlook...
