Area Forecast Discussion National Weather Service Mount Holly NJ 316 PM EDT Tue Oct 14 2025

.SYNOPSIS... Low pressure off the coast continues to move away into the North Atlantic. A cold front will move through the area on Wednesday, with strong high pressure building in to close out the week. A low pressure system may approach from the west late this weekend into early next week.

&&

.NEAR TERM /THROUGH WEDNESDAY/... The coastal low which has impacted the Mid-Atlantic region over the past several days has finally moved out to sea as high pressure is centered over the Great Lakes. The region today is caught in between systems as stubborn cloudiness persists. However, some breaks of sun are starting to peak out where cloud cover will continue to dwindle away towards sunset and more so tonight. Partly cloudy skies should prevail overnight for most, although clouds may linger a bit longer toward the coast. All in all, dry weather is anticipated. Winds will also subside overnight to around 10-20 mph. Lows tonight fall into the mid 40s to mid 50s.

For Wednesday, more in the way of sunshine is expected throughout the course of the day aside for some high clouds. In the morning, a cold front approaches from the north before crossing through the area during the afternoon. Winds will once again become increasingly gusty after the front passes where northwest winds may gust up to 30 mph in the afternoon. Despite the frontal passage, afternoon highs will be noticeably warmer with highs topping out in the mid 60s to low 70s for most, with 50s in the Poconos.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/... Cold advection will persist thru Wednesday night as high pressure builds in from Canada, resulting in a steady northwesterly wind. Skies should be mostly clear, and lows will drop down into the upper 30s and low 40s.

With the high taking its time building into the area, we`ll keep a northwesterly gradient, so the northwest winds will remain steady and occasionally gusty on Thursday. Otherwise, skies will be mostly sunny, but temperatures will only recover to the upper 50s and lower 60s.

It still appears the gradient will remain tight enough Thursday night, with the high center still off to the northwest, such that we`ll mostly avoid a frost/freeze threat in locations where the growing season continues. The steady breeze will remain, though a bit weaker than Wednesday night. Lows Thursday night in the mid 30s to lower 40s.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/... High pressure finally builds overhead Friday, allowing winds to relax more as the cold advection finally dwindles. Another mostly sunny day should help to bring temps up a little, with highs in the low to mid 60s, except upper 50s in the Poconos.

The highs sinks to our south on Friday night, with warm advection beginning aloft as the gradient turns westerly, though remaining light. Some clouds may filter into the area as well. Lows Friday night in the 40s.

A weak warm frontal passage on Saturday should bring a bit more cloud cover, but also notably warmer temperatures. Highs Saturday in the mid 60s to low 70s.

Warm advection on a southwesterly gradient will continue Saturday night, but remaining dry with high pressure still in control as it drifts off the Carolina coast. Lows Saturday night in the upper 40s to mid 50s.

Warm advection peaks on Sunday just ahead of the next frontal system approaching from the west. Clouds will be increasing, along with the risk of showers, but it still should be the warmest day of the forecast period. Highs Sunday in the low to mid 70s, except 60s in the Poconos.

Aforementioned front moves through Sunday night, with widespread showers and maybe even some thunderstorms and locally heavy rain, depending on how the details set up. Lows Sunday night in the upper 40s to mid 50s.

High pressure starts building back in Monday, with decreasing clouds and precip chances. Highs Monday in the 60s, except 50s in the Poconos.

.AVIATION /19Z TUESDAY THROUGH SUNDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Through 00Z...MVFR ceilings are to prevail at most terminals through 22Z before lifting to VFR. MVFR ceilings will likely linger at KMIV/KACY though. North winds around 8-13 kt with gusts up to 18-20 kt possible. Moderate-high confidence.

Tonight...Lingering MVFR ceilings at KMIV/KACY early, otherwise VFR expected for most of the night. North-northwest winds around 5-10 kt. Moderate-high confidence.

Wednesday...VFR with SCT high clouds. Northwest winds around 10 kt occasionally gusting up to 20+ kt. High confidence.

Outlook...

Wednesday night thru Saturday...VFR conditions should prevail.

Sunday...Restrictions likely developing late as low clouds and rain move in ahead of an approaching cold front.

&&

.MARINE... The Small Craft Advisories on the Atlantic coastal waters are in effect through Wednesday. The Small Craft Advisories on the Delaware Bay have been cancelled today, however a new Small Craft Advisory has been issued beginning at 4 PM on Wednesday.

Northerly winds around 15-20 kt with gusts up to 25 kt will continue into tonight before diminishing after midnight. On Wednesday, north- northwest winds around 10-15 kt in the morning will increase to 15- 20 kt in the afternoon with gusts up to 25 kt following a frontal passage. Seas of 6-10 feet. Fair weather outside of SCA conditions.

Outlook...

Small Craft Advisory conditions look likely at times Wednesday night thru Thursday night due to winds and/or waves, at least on the ocean waters. Delaware Bay will naturally have more sub- advisory periods.

Sub-SCA conditions should become more widespread Friday and continue thru Saturday.

Sunday will see increasing southerly winds and seas building over 5 feet. Advisory conditions likely. Rain developing late Sunday.

&&

.TIDES/COASTAL FLOODING... Surge values are slowly subsiding as the coastal storm moves away. However, one final high tide cycle is forecast to reach widespread minor this afternoon. The Coastal Flood Advisory remains in effect for the back bays of Ocean, Atlantic, Cape May, and Sussex Counties, and Kent (DE) for Delaware Bay until 8 PM this evening. Thereafter, winds turning northwest should allow water levels to subside even more. Some minor flooding could linger in Ocean and Sussex Counties, but will see how things trend today before making any additional advisory extensions.

No tidal flooding is expected for our eastern shore counties along Chesapeake Bay, or the tidal Delaware River.

&&

.PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...Coastal Flood Advisory until 8 PM EDT this evening for NJZ020- 022>027. DE...Coastal Flood Advisory until 8 PM EDT this evening for DEZ002>004. MD...None. MARINE...Small Craft Advisory from 4 PM Wednesday to 6 AM EDT Thursday for ANZ430-431. Small Craft Advisory until 6 AM EDT Thursday for ANZ450>455.
