Area Forecast Discussion National Weather Service Mount Holly NJ 1040 AM EDT Sun May 5 2024
SYNOPSIS
A warm front will lift north through the region today, and then a cold front works its way through the region late Monday and Monday night. This boundary will become stationary over the area through the mid-week period. A series of disturbances will track along this boundary through the middle of the week. A stronger area of low pressure moves through the region on Thursday, followed by a cold front on Friday.
NEAR TERM /THROUGH TONIGHT/
Weak warm advection overruning a very moist and cool marine layer will keep low clouds and light rain showers for most locations for the rest of the day. Forcing will be maximized over the Lehigh Valley, but as a shortwave moves over the region, the area of showers will push east through the afternoon and evening. Temperatures will be in the upper 50s/low 60s, though as a warm front advances slowly northward, some areas in lower Delmarva will reach the upper 60s to lower 70s.
The bulk of the rain moves out late this evening, but a cold front approaching tonight will reinforce lift and generate additional showers. Some of the model soundings show some elevated instability, so can't rule out some lightning strikes late tonight, mainly within Delmarva and the southern half of New Jersey, along and south of the warm front. Some patchy fog is possible with a moist boundary layer, greatest chance mainly north and west of the Philadelphia metro. It will be a mild night, with lows in the mid to upper 50s/low 60s.
SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/
Cold front will be west of the area Monday morning. Southerly flow ahead of that front will usher an increasingly humid airmass into the region with surface dewpoints rising into the 60s. Areas of fog will develop in the morning, and then will lift and dissipate by midday or so. The cold front passes through the region Monday afternoon and Monday evening. Some shortwave energy passing through the region will help kick off afternoon and evening showers and thunderstorms, mainly across the southern portions of the forecast area.
The front becomes stationary south of the region Monday night through Tuesday night. High pressure builds north of the region, and an onshore flow develops, bringing somewhat cooler and drier air down into the region. Another disturbance approaches from the west late Tuesday and Tuesday night, touching off another round of scattered showers and thunderstorms over the region.
LONG TERM /WEDNESDAY THROUGH SATURDAY/
A prolonged period of unsettled weather on tap for the latter part of the new week. A series of frontal boundaries and weak low pressure systems will pass through the region during this time. The first system is an area of low pressure that will pass north of New Jersey Wednesday morning, and this will drag a cold front through the region late in the day and at night. Some rain is possible in the morning, and then another round of showers and mostly isolated thunderstorms will affect the area Wednesday afternoon and Wednesday evening.
The next area of low pressure will organize and develop over the Midwest, and a warm front will develop out ahead of this system and lift towards the local area late Wednesday night/early Thursday morning. This will touch off some more showers and isolated thunderstorms during this time. A secondary low will form over the Mid-Atlantic ahead of the primary low, and this low works its way across the region Thursday afternoon and Thursday night. More widespread showers and scattered thunderstorms will affect the area during this time.
The primary low passes north of the region on Friday with yet another round of showers as a cold front passes through the region.
Temperatures during the period will start out warm with highs in the 80s on Wednesday,and then temperatures will trend closer to normal on Thursday and Friday.
AVIATION /15Z SUNDAY THROUGH THURSDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Monday through Thursday...No significant weather expected Monday through Thursday morning. Widespread showers and thunderstorms Thursday afternoon.
MARINE
No marine headlines expected through tonight as seas will be 2 to 4 feet with winds out of the east/southeast around 10-20 kt. Periods of showers expected, with a 15-20% chance of thunderstorms early Monday morning.
Outlook...
Monday through Thursday...A prolonged period of sub-SCA conditions. VSBY restrictions in fog throughout the week, especially at night. Best chances for widespread showers on Thursday afternoon.
