Area Forecast Discussion National Weather Service Mount Holly NJ 506 PM EDT Thu May 9 2024

SYNOPSIS
Weak high pressure will remain across the northern Middle Atlantic region into the evening. After that, several waves of low pressure affect our area with the unsettled patterned continuing from later tonight through Sunday. High pressure builds south of the Mid-Atlantic region Sunday night into Monday. More unsettled weather may impact our area next week.

NEAR TERM /THROUGH FRIDAY/
Weak high pressure was across the area much of the morning and for the start of the afternoon. Low pressure well to the west is moving rather quickly along the front (to our south) and will bring poorer conditions for the evening and overnight. Showers have already developed across southern NJ and northern Delmarva but most of this activity is rather light and is diminishing. More rains will develop and move across the region this evening and then become steadier overnight. Low pressure will move offshore by Friday morning and a NE flow around the N side of the low will bring low clouds and rains to the region late tonight.

For Friday, the low will continue to move offshore, but an upper trough and lingering low level moisture will keep plenty of clouds and rains across the area Friday.

SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/
Unsettled weather will continue through Sunday with a brief reprieve during the day on Saturday. PoPs remain in the 35-45 percent range Friday night as the low continues to move offshore but by early Saturday, the low looks to be far enough away that conditions should be mostly dry regionwide. Lows Friday night will be mainly in the mid-upper 40s and highs Saturday will warm back into the low 60s.

By later in the day Saturday though, the next wave of low pressure will arrive out of the Great Lakes, increasing chances for showers, particularly northwest of the I-95 urban corridor. Showers continue to move into the region Saturday night (PoPs 45-55 percent) with lows again in the mid-upper 40s. Chances for rain will linger into Sunday as well with highs once again in the low 60s.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
A brief period of dry weather is expected beginning Sunday night and continuing into Monday as high pressure briefly builds to the south of the Mid Atlantic region. This dry weather will only be brief as chances will begin to increase Tuesday night into Wednesday as a storm system approaches from the southwest.

AVIATION /21Z THURSDAY THROUGH TUESDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas...

into the evening... Mostly VFR with scattered showers. A brief period of lower CIG/VSBY possible. Light variable winds probably favoring NE or E most spots. Medium/high confid.

Tonight...Rain/showers becoming heavier and steadier with some patchy fog likely as well. Cigs lowering to MVFR through the evening with IFR cigs likely overnight. East winds around 10 knots. Moderate confidence.

Friday...Rain/showers continuing with conditions remaining IFR likely through at least the first half of the day with some improvement to low MVFR possible by afternoon. East to northeast winds around 10 knots with some gusts to 15-20 knots. Moderate confidence.

Outlook...

Friday night-Sunday...Sub-VFR conditions probable (50-60 percent chance) at times through the period with chances (40-50 percent) for showers.

Sunday night-Tuesday...VFR conditions expected through Monday. Sub- VFR conditions with chances for showers return late Tuesday.

MARINE
No significant changes in the thinking with regards to the marine forecast. sub-SCA winds and seas continue thru the evening as showers increase over the waters. SCA flags go up overnight from N to S across our waters as winds/gusts slowly build. We have extended the timing of the SCA flags further into Friday as seas will be slower to diminish. Rain and fog late tonight and into Friday.
Thunder possible for the waters off Delaware.

Outlook...

Friday night and Saturday...Small Craft Advisory in effect for Atlantic Ocean coastal waters through Saturday morning. Seas of 5-6 feet expected with winds gusting 20-25 knots. Sub-SCA conditions on the Delaware Bay. Sub-SCA conditions return later in the day Saturday.

Sunday through Tuesday...Overall, mainly sub-SCA conditions expected through Monday. Stronger winds may bring SCA conditions back late Monday into Tuesday.

TIDES/COASTAL FLOODING
The new moon occurred Tuesday, May 7th, and this is resulting in high astronomical tides. As a front settles to our south, an onshore flow will develop and strengthen some through the end of the week, peaking Friday into Friday night. While the astronomical tides will be gradually lowering as we get farther away from the new moon, the onshore flow should increase the surge values at least some. With this combination, widespread minor tidal flooding is again expected with the high tide tonight into early Friday morning for the Atlantic coastal zones, the Delaware Bay, and the tidal Delaware River. As a result, the Coastal Flood Advisories remain in effect for these areas.

With the peak onshore flow leading up to the Friday night high tide cycle, guidance continues to support potential for moderate tidal flooding for portions of Atlantic coastal New Jersey and Delaware, as well as Delaware Bay with the Friday night to early Saturday morning high tide cycle. The Coastal Flood Watch was expanded to include southeastern Burlington and Ocean Counties. As of the 5 PM Thursday forecast update, our confidence is highest that coastal Sussex (DE) and Cape May Counties are the most likely locations to see moderate coastal flooding impacts Friday night, thus the Coastal Flood Watch was upgraded to a Warning for those two counties.

Elsewhere within the Coastal Flood Watch area, there is somewhat lower confidence that moderate tidal flooding impact will be experienced. Thus, the Watch remains in effect.
Regardless, widespread minor tidal flooding is expected within the Watch area and adjacent areas of the Atlantic coast of New Jersey, Delaware Bay, and the tidal Delaware River with the Friday night to early Saturday morning high tide cycle.
Examination of tonight's observed water levels and surge values and additional guidance will be used to determine which areas will need to be upgraded to a warning or to an advisory for Friday night.

The Friday night high tide cycle looks to be the peak of the coastal flooding impacts area-wide, but additional minor coastal flooding is forecast with the evening/overnight high tide Saturday night into early Sunday.

Flooding is not expected at this time for our Maryland zones along the Chesapeake through Saturday.
