| Area Forecast Discussion National Weather Service Mount Holly NJ 111am EST Sat Nov 15 2025 Synopsis High pressure near Hudson Bay builds down into the region today, then departs by tonight as a warm front associated with a clipper system moving into the Great Lakes lifts into the region. This clipper system passes north of the region on Sunday. High pressure then builds down into the Great Plains states on Monday, passing off the Mid-Atlantic coast on Tuesday. Weak low pressure may affect the area Wednesday. High pressure returns to close out the new work week. Near Term - Through Tonight There is a chance for light rain late today and tonight as a warm front lifts through the region. It is a brief window that we could see any rain, and there isn't any strong signals for heavy rain, so expecting rain amounts to generally be less than one quarter inch. At this point, the risk for any other hazards appears very low. The showers should precede the low level jet progressing over our region, and thus the risk for any stronger winds mixing down is low. Additionally, given the timing, instability (even elevated instability) is going to be very limited. So while I can't rule out occasional lightning, even that threat is limited. Short Term - Sunday Through Monday Night Low pressure will pass north of the area Sunday morning, and a strong cold front follows through. A tight pressure gradient forms over the area between low pressure over eastern Canada and New England and high pressure building down into the Northern and Central Plains states. Cold air advection will not be underway until late Sunday and Sunday night. As a result, highs on Sunday will generally be early in the day, and should be in the mid to upper 50s for most of the region and in the low 60s for extreme southern New Jersey and Delmarva. The main story on Sunday and Sunday night will be the strong west to northwest winds which will be increasing to 15 to 25 mph with 30 to 40 mph gusts. With loss of diurnal heating Sunday night, winds will diminish to 15 to 20 mph with gusts up to 30 mph. Gusty conditions continue into Monday. This situation tends to result in Lake Effect snow well to the north and west, and some of those snow showers may encroach the southern Poconos and far northwest New Jersey, but accumulating snow is not expected. Lows Sunday night drop into the low to mid 30s. With cold air advection underway, highs on Monday will be much colder, generally in the mid to upper 40s. Cold Monday night with lows ion the upper 20s to low 30s, though generally warmer in the urban environments and along the coasts. Long Term - Tuesday Through Friday High pressure moves off the Southeast and Mid-Atlantic coasts on Tuesday, and weak low pressure passes through the region Tuesday night and departs Wednesday morning. While some wintry precipitation is possible for the higher elevations of the southern Poconos and far northwest New Jersey, rain will be the dominant p-type. High pressure then builds down into the Great Lakes and Ohio Valley Thursday and moves offshore Friday. Another storm system may approach on Friday, but there are timing and placement inconsistencies. For now, will follow the NBM and carry chance Probability of Precipitation (30 to 40 percent). Temperatures will be warm enough to support rain throughout. Temperatures will be seasonably chilly for this time of the year, warming back to above normal levels by Friday. Marine As of 1 AM, winds at buoy 44065 are flirting with 25 kt. However, winds are expected to decrease shortly. Across the area, winds and seas should stay below Small Craft Advisory Criteria through the day time hours today as the direction gradually shifts from northerly to southerly. By this evening, southerly winds are expected to increase on all waters. Therefore, have issued a Small Craft Advisory for the overnight period. We could see an abrupt shift to southwesterly or even westerly winds very late tonight into early Sunday morning. Outlook... Sunday through Monday...A Gale Watch is in effect for Delaware Bay and the Atlantic coastal waters. West to northwest winds will range from 20 to 30 kt with 35 to 40 kt gusts. Winds begin to diminish Monday afternoon. Monday night...Lingering Small Craft Advisory conditions, diminishing late. Tuesday through Wednesday...Sub-SCA (Small Craft Advisory) conditions. NOAA Mount Holly NJ Office: Watches - Warnings - Advisories PA...None. NJ...None. DE...None. MD...None. Marine Small Craft Advisory from 6pm this evening to 6am EST Sunday for ANZ430-431-450>455.
