| Area Forecast Discussion National Weather Service Mount Holly NJ 237pm EST Thu Nov 13 2025 Synopsis High pressure will slowly shift eastward into the area through Saturday. Low pressure will approach the area Saturday night, with a warm front passing through the area. A cold front will move through on Sunday. A few reinforcing shots of cool air arrive Sunday into Monday, with high pressure gradually building back in through mid-week. Near Term - Through Friday After the exciting snow and graupel squall across the Poconos and northern NJ earlier today, overall conditions are quieting down. There may still be a few rain/snow showers/sprinkles/flurries into early this evening, but overall precipitation intensity should be notably lighter than the earlier activity, which was supported by a potent upper trough shortwave and vort max moving through. Upper troughs begins to very gradually move out of the region tonight and Friday, but additional shortwaves with notable vorticity maxima will continue crossing southeastward towards us, so a few more stray rain/snow showers may persist into Friday at times, supported by continued northwesterly surface flow. However, most of the time will be dry, especially south of I-78. Clouds will diminish tonight as insolation ends, but will return tomorrow after the sun rises and just enough instability builds to get the stratocumulus growing again. Overall however, expect it to be a little less cloudy on Friday as compared to today. Also expect continued gusty northwest winds, diminishing tonight after sunset but returning after sunrise on Friday, but with the gradient diminishing a bit, winds should also be a bit lighter, with gusts of 20-30 mph instead of 30-40 mph. The clouds this evening and continued, if diminished wind overnight will likely keep much radiational cooling from occuring, so temps probably end up near freezing for much of the region, a bit warmer urban centers and immediate coast, and upper 20s Poconos and NW NJ. Highs on Friday should be fairly close, perhaps a touch lower, than today, with low-mid 50s for most of the region, 40s Poconos and NW NJ. Short Term - Friday Night Through Sunday For Friday night and Saturday morning, Fair weather continues with high pressure still in control. Increasing clouds during Saturday with the next system arriving from the NW for the afternoon. Seasonably cold temps Friday night, but then near normal high temps for Saturday as a southwest flow develops ahead of the approaching system. Highs Sat will range from the upper 40s/low 50s N/W to the low 60s for Delaware and south NJ. After that, deep low pressure across southern Canada causes a few surface fronts to approach from the west. Pooling moisture and increasing warmth will cause showers to develop along the front Saturday before it moves through overnight and into Sunday morning. We'll have chance and slight chance probability of precipitation (20% - 30%) for the west of I-95 areas Saturday afternoon and then higher probability of precipitation for Saturday night. probability of precipitation Sat night range from chance (40% to 50%) for southern Delmarva, likely (60%-70%) for most other areas south NJ and northern Delaware and categorical (80%-90%) for the rest of the area. probability of precipitation drop off to slight chance by Sunday morning before going dry by Sunday afternoon. Temperatures will be near normal Saturday but then go above normal Sunday before the front moves thru. Highs Sunday will be mid/upper 50s N/W and low mid 60s S/E. Long Term - Sunday Night Through Thursday The mild weather from the weekend will be a memory once next week begins as upper low pressure across Eastern Canada spins in place Monday/Tue. During the midweek period, the low moves away allowing upper heigheights to rise across the Middle Altantic region. These features will bring below normal temps for much of the Mon-Thu period and near normal reading after that. Normal temps for this time of year range from highs in the mid/upper 50s S/E to upper 40s/low 50s N/W. Lows are typically in the low 30 for the northern areas and close to 40 for Delmarva and SE NJ. Not much in the way of precipitation expected next week. An exception will be a weak and fast moving shortwave/weak surface low which will move WNW to ESE along a front well to our south. There have been changes with this feature between the 12Z and older 00Z model runs. The GFS (Global Forecast System) seems quicker and more across our area with the precip, others more suppressed and slower. The rains seem to affect only Delmarva, southeast PA and south NJ. We'll continue with the NBM probability of precipitation which generally run in the 20% to 30% range. Marine Small Craft Advisories in effect for all waters rest of this afternoon. West to northwest winds will range from 15 to 20 kt with 25 to 30 kt gusts with seas on the ocean generally 3 to 5 feet. Winds on Delaware Bay will diminish to sub-SCA (Small Craft Advisory) criteria this evening, but strong winds will continue on the ocean waters. Will keep SCA (Small Craft Advisory) in effect until 6 pm for Delaware Bay and will extend the SCA (Small Craft Advisory) until 6 pm Friday for the ocean waters. Outlook... Friday night through Saturday...No marine headlines are anticipated with winds below 25 kt and seas below 5 feet. Saturday night through Monday...Marine headlines will likely be needed for part or all of this time period. Southerly wind Saturday night will transition to west-northwesterly on Sunday. Winds 25-30 kt are possible. While not likely at this time, a period of gales cannot be entirely ruled out. Seas increase to 4-7 feet.
