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 430 AM EDT Sat May 4 2024

SYNOPSIS
High pressure over New England will maintain an onshore flow through the next few days. A series of cold fronts approaches from the west through the weekend, with the second (and stronger of the two) front stalling out nearby by early next week. The stalled front lifts north as a warm front at some point in the Tuesday/Wednesday timeframe, bringing a return to above normal temperatures.

NEAR TERM /THROUGH TONIGHT/
The base of high pressure centered over New England extends down into the Mid-Atlantic. An old warm front lies over the Appalachians, and a cold front is moving through the Great Lakes and into the Ohio Valley. High pressure slowly lifts to the north and east throughout the day today and into tonight. Several shortwaves will approach from the west, pushing those frontal boundaries towards the local forecast area.

The first shortwave is moving through Maryland, and showers with isolated thunderstorms will move into the eastern shores of Maryland early this morning. Some brief downpours and a few rumbles of thunder can be expected. Those showers will taper off after sunrise as they run into the base of the high. Elsewhere, some marine stratus will move into portions of New Jersey and southern Delaware.
That stratus will dissipate later this morning, but skies remain cloudy through the day as showers continue to develop well west of the region. Those showers will slowly track east, not making it into the far western portions of the forecast area until late in the afternoon and early evening. A cool day with highs in the 50s to low 60s, which will be some 10 to 15 degrees below normal for this time of year.

Best chances for showers will be during the overnight period tonight, mainly for inland areas as those frontal boundaries wash out as they approach.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/
A cold front approaches from the west on Sunday. With a slower approach, showers will mainly be north and west of the Philly metro through the morning, before pushing over the rest of the area through the afternoon and evening. The marine airmass in place will keep things stable, and really not expecting much in terms of thunder or heavy rainfall Sunday/Sunday night. Rainfall amounts will generally be around a quarter to three quarters of an inch of rain, spread out over a rather large period, so not expecting much in terms of hydro concerns. Temperatures will be in the upper 50s/low 60s, though some spots in the Delmarva will get into the upper 60s/low 70s. Temperatures won't drop much on Sunday Night, likely staying in the 50s.

For Monday, temperatures moderate as a weak west/southwesterly flow takes over. The first of several shortwaves next week is expected to traverse the area, with some showers and thunderstorms potentially developing in the afternoon and evening. Some of the model soundings show decent instability with marginal shear, so can't rule out a strong to severe thunderstorm late Monday.
However, not expecting the threat to be widespread at all. Will continue to monitor as we get in range of CAM guidance. Best chance to see any convection will be over Delmarva and southern New Jersey. Temperatures will be in the upper 70s/low 80s on Monday with mid to upper 50s/low 60s on Monday Night.

LONG TERM /TUESDAY THROUGH FRIDAY/
Unsettled conditions are expected for most of the week as a rather progressive pattern will be in place. Several shortwaves are expected to pass over the region. Lift will also be aided by a stalled boundary bisecting the area that will meander for the middle and end of next week. The front looks to venture northward on Tuesday into Wednesday, resulting in a period of above normal temperatures with upper 70s/low 80s expected. With a relatively warm and moist airmass in place, incoming shortwaves could potentially spark some showers and thunderstorms Tuesday/Wednesday PM. Wednesday afternoon/evening looks to be the most active in terms of convective weather, though too early to see if severe weather is on the table.

The stalled boundary retreats southward towards the end of the week with onshore flow likely taking over, at least along the coastal plain. Depending on where this stalled boundary sets up will have implications on temperatures and thunderstorm potential on Thursday/Friday. Areas near and east of the front will be under the influence of the marine layer with cooler and more stable air, while areas west of the boundary are more unstable with warmer temperatures. A deepening trough will begin to move into the Mid- Atlantic, with a series of shortwaves/frontal systems moving through both Thursday/Friday. Both days will feature temperatures near/below normal, depending on where this lingering boundary sets up.

Important to note that there remains a lot of uncertainty with the long-term forecast as models tend to struggle with a progressive pattern like this, and the placement of this boundary that will hang around through next week. As mentioned before, where that boundary sets up will have large implications on the forecast. We look to potentially shake this unsettled pattern once a sweeping cold front comes through late next week/early next weekend.

AVIATION /09Z SATURDAY THROUGH WEDNESDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today...MVFR and IFR CIGs at KMIV/KACY this morning, eventually lifting to VFR by this afternoon. MVFR CIGs at KTTN/KPHL/KPNE/KILG through daybreak will give way to VFR conditions. At KRDG/KABE, VFR. MVFR CIGs will spread from west to east starting at KRDG/KABE around midday, then MVFR CIGs will spread towards KACY prior to 00Z. SHRA arrive at KRDG/KABE prior to 00Z as well. E to SE winds 10 to 15 kt. Moderate confidence.

Tonight...IFR conditions in stratus/BR/SHRA tonight. E winds 5 to 10 kt. Low confidence.

Outlook...

Sunday through Sunday Night...MVFR/IFR conditions expected with low ceilings. Reduced visibility likely with showers.

Monday through Monday Night...Conditions gradually improve as the day goes on, likely back to VFR, though some showers/thunderstorms develop for the afternoon/evening, with restrictions possible if any storms move over the terminals.

Tuesday through Tuesday Night...Primarily VFR though some restrictions possible with 20-40% chance of SHRA.

Wednesday...Sub-VFR conditions possible (30-50%) with scattered showers/thunderstorms expected, especially in the afternoon/evening.

MARINE
Sub-Small Craft Advisory conditions on tap today and tonight with E to SE winds 10 to 15 kt with gusts up to 20 kt and 3 to 4 ft seas.
