Area Forecast Discussion National Weather Service Mount Holly NJ 705 AM EDT Tue May 21 2024

SYNOPSIS
High pressure shifts slightly to the south today then out to sea Wednesday. A cold front will approach the area Wednesday night, before slowly moving across the area on Thursday, then stalls to our south through the weekend. Several waves of low pressure and may develop and move along this boundary over the weekend into early next week, bringing unsettled weather to the area.

NEAR TERM /THROUGH TONIGHT/
Areas of fog and low stratus are beginning to overspread southern NJ, coastal DE, and southeast PA early this morning. Expecting coverage to gradually increase over the next several hours until daybreak arrives and begins to mix out any fog or low stratus.

Fog and/or low stratus this morning will dissipate by mid-morning and give way to clear skies in the afternoon with some fair-weather cumulus. Another dry and quiet weather day is expected. High temps should be a bit warmer than those of today, rising into the upper 70s to mid 80s. Temps will be noticeably cooler along/near the shore thanks to light surface winds allowing an afternoon sea breeze circulation to develop.

Another tranquil night with mostly clear skies and calm winds. Light SSWrly flow should inhibit much organized fog outside the immediate coast, but some patchy fog will be possible. Lows in the mid 50s to around 60.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/
High pressure will move farther away from the area and out to sea on Wednesday, losing its effect on the weather across the area. Dry conditions are expected early in the day on Wednesday, but showers will be possible by the end of the day as a mid/upper level disturbance moves in to the area. Showers and thunderstorms become more likely on Wednesday night as a pre-frontal trough may develop across the area while the aforementioned mid/upper level disturbance slowly moves across the area. Showers and thunderstorms become even more likely on Thursday and into Thursday evening as the cold front moves across the area. There is some instability forecast across the area, with CAPE values potentially reaching 1000-2000 J/kg, with some shear across the area with 30-40 knots. So there will be the potential for some strong to severe storms to develop across the area.

LONG TERM /FRIDAY THROUGH MONDAY/
The cold front is expected to stall to the south Friday and into the weekend, before possibly lifting north of the area on Monday.
leading to possible unsettled weather. A couple of waves of low pressure are expected to move across the area as the front stalls near the area Friday and Saturday. This will lead to a period of possible unsettled weather with a chance of showers and thunderstorms. As these disturbances move to the east Sunday, it is possible that the shower activity will diminish on Sunday. However, another area of low pressure could begin to move into the area Sunday night into Monday, bringing addition unsettled conditions to the area.

AVIATION /12Z TUESDAY THROUGH SATURDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas...

Tuesday night...Prevailing VFR. Light and variable winds. Some patchy fog possible, but forecast currently does not call for anything more widespread than that. Moderate confidence.

Outlook...

Wednesday...Generally VFR except lower conditions possible around daybreak.

Wednesday night-Thursday night...Sub-VFR conditions possible with a chance of showers and thunderstorms.

Friday...VFR conditions expected with a slight chance of showers during the day.

Friday night-Saturday...Chance of showers with periods of lower conditions possible.

Light and variable winds this morning will become more S to SSW this afternoon into the overnight period around 10-15 kt with occasional gusts up to 20 kt. Seas 2-3 feet.

Outlook...

Wednesday-Saturday...Conditions expected to remain below Small Craft Advisory levels. However, winds will gust around 20 knots at times and seas could rise to 4 feet at times.

Rip Currents...

Winds today will increase to 5-15 mph from the south to southeast, while waves offshore waves will be 3-4 feet with an 8 second swell. Also, there is a full moon on Thursday. This will all contribute to a Moderate risk for the development of dangerous and life threatening rip currents for the beaches both Delaware and New Jersey.

Similar conditions will continue into Wednesday, with slightly stronger winds. As a result, there will continue to be a MODERATE risk for the development of dangerous and lift threatening rip currents at NJ and DE beaches on Wednesday.
