Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay - High pressure lingers through the remainder of the day, before a series of fronts and low pressure systems affect the east coast Wednesday through the end of the week. High pressure looks to return to end the weekend and start the new week.

Area Forecast Discussion National Weather Service Mount Holly NJ 948 PM EDT Mon May 6 2024

SYNOPSIS
A cold front will work its way through the region tonight before becoming nearly stationary south of Delmarva. Low pressure tracks along the front late tonight through Tuesday morning. Another area of low pressure passes through the region on Wednesday followed by a stronger low on Thursday. A cold front passes through on Friday, then several disturbances are possible this weekend.

NEAR TERM /THROUGH TODAY/
As of 945 PM, most of the low clouds have dissipated although some stratus is redeveloping along the southeast New Jersey coastal areas. Plenty of high level cloudiness continues to stream across the area. The lack of lower clouds has resulted in temperatures dropping a little faster for many places and some localized fog is also starting to develop. At least some low clouds should expand across at least the southern half of the area overnight along with some fog. The arrival of some drier air from the north overnight in the wake of a weak cold front may limit the fog development and therefore kept it as patchy for now. An area of weakening convection is sliding by to our south this evening, with the the northern edge of showers getting into southern Delaware and adjacent Maryland. The lightning is on the decrease with all of it to our south. Some convective cells may still develop overnight in Delmarva therefore opted to keep the slight chance of thunder. Opted to shift the higher PoPs southward some more as much of the guidance not showing much north of Delmarva. Made some tweaks to the hourly temperature and dew point grids to keep them current based on the latest observations.

Otherwise, a cold front will slowly slide south across the area tonight and with a weak wave of low pressure track along it the best best forcing for ascent and RH is across the southern areas (highest PoPs will be here for the overnight). Overnight lows will be in the lower 50s to lower 60s.

Weak low pressure will be just east of Delaware Tuesday morning.
This will keep some showers in the forecast through at least the daybreak hours. Some showers and possibly a few thunderstorms are expected to decrease by lunchtime as low pressure moves offshore. PoPs won't be zero for the remainder of the day for all areas, but the most showers should be in the morning. Afternoon highs will be in the 70s for most places.

Another area of low pressure will track from the Great Lakes into the Ohio Valley. A warm front extending out from that system will lift towards southwest portions of the area later in the day.

SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/
Another area of low pressure will track from the Great Lakes into the Ohio Valley. A warm front extending out from that system will lift towards southwest portions of the forecast area Tuesday night.
Scattered showers and thunderstorms will develop in the evening and then become likely for most of the region after midnight Tuesday night and into Wednesday morning as that warm front lifts through the region. Precipitation tapers off by midday Wednesday, and then a warm and humid airmass will be in place. Highs top off in the mid to upper 80s, except for the low 80s in the southern Poconos and northern New Jersey, and in the 70s along the coasts. Surface dew points will be in the upper 50s to low 60s in the afternoon.

Low pressure approaches from the west Wednesday night, and scattered showers and isolated thunderstorms will move into portions of southeast Pennsylvania and Delmarva late Wednesday night. As the main surface low tracks towards western New York and Pennsylvania, a secondary low will develop out ahead of this primary low, resulting in more widespread showers with scattered thunderstorms moving into the region Thursday afternoon and evening as a warm front lifts north of the region.
Global guidance has indicated some instability as the warm front lifts north, suggesting the potential for some strong to severe thunderstorms south of the warm front during the afternoon, but exactly how far north the warm front progresses will greatly determine the coverage of any strong to severe storms in our forecast area. At the moment, it remains too uncertain to mention anything more specific at this time. Even the afternoon high temperatures will be highly variant on where the warm front ends up, with low to mid 60s north of the front and mid to upper 70s south. Showers and storms will taper off Thursday night as the storm system shifts offshore.

LONG TERM /FRIDAY THROUGH SUNDAY/
A cold front will push through the region Friday afternoon and evening. Yet another round of scattered showers and isolated thunderstorms will affect the area during that time.

Behind the cold front, surface high pressure builds east.
Several weak disturbances may touch off some afternoon showers on Saturday and Sunday.

Highs will then be in the 60s for southeast Pennsylvania and New Jersey and in the low to mid 70s in Delmarva on Friday.
Below normal highs expected for Saturday and Sunday, generally in the low to mid 60s.

AVIATION /02Z TUESDAY THROUGH SATURDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight...VFR conditions overall (IFR/LIFR at KACY) this evening lower to MVFR and IFR overnight (locally LIFR possible). Some fog is expected. Some showers overnight mainly near KMIV and KACY. West-southwest winds 3-5 knots becoming mostly light and variable to locally calm. Low confidence on the timing details of the developing sub-VFR conditions and how widespread the fog will become.

Tuesday...Areas of MVFR/IFR for a time in the morning, then conditions improve to VFR. Some mainly morning showers possible mainly near KACY and KMIV. Light and variable winds, becoming east-northeast to east-southeast around 5 knots then becoming locally southwest in the afternoon. Low confidence on timing details when conditions return to VFR and also wind shift details given light speeds.

Outlook...

Tuesday night through Saturday...Sub-VFR conditions at night in fog and stratus, while VFR conditions overall during the day.
Chances for SHRA/TSRA throughout the period with sub-VFR conditions. More widespread SHRA with scattered TSRA Thursday afternoon and evening.

MARINE
Tonight through Tuesday...The conditions are expected to remain below Small Craft Advisory criteria. Some fog, possibly dense, improving during Tuesday.

Outlook...

Tuesday night through Saturday...Overall, sub-SCA conditions through the period. Scattered showers and thunderstorms will result in locally higher wind gusts and seas, with biggest impacts coming on Thursday afternoon and evening.

TIDES/COASTAL FLOODING
Tidal ranges increasing this week as the new moon arrives Tuesday evening. Limited onshore flow means that there won't be much in the way of serious flooding concerns, but still minor tidal flooding is possible beginning tomorrow evening and perhaps Wed/Thu evening as well. A Coastal Flood Advisory may be issued overnight if trends remain.

PHI WATCHES/WARNINGS/ADVISORIES
PA...None.
NJ...None.
DE...None.
MD...None.
