Area Forecast Discussion National Weather Service Mount Holly NJ 1002 PM EDT Fri Apr 19 2024

SYNOPSIS
A cold front moves across the region tonight, then continues to track south and east of the region through the weekend. High pressure builds in from the west and will be over the area into the middle of next week. A cold front passes through on Wednesday, followed by high pressure to close out the week.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
First batch of light showers have reached the coastline and will move offshore over the next few hours. Additional rounds of light showers can be expected overnight. Otherwise, overcast through the rest of tonight as weak onshore flow funnels in moisture under an inversion. Rainfall amounts up to two tenths of an inch are possible, so not expecting anything impactful overall. Can't rule out some patchy fog tonight, especially along the coast and within the higher elevations of NW NJ and the southern Poconos. Temperatures overnight won't drop too much, hovering in the mid to upper 40s.

The cold front moves offshore tomorrow morning, and shower chances end within the coastal plain by the late morning. Skies should clear out relatively quickly as dry air moves in, and we will see the sun for the first time in days. It will be a much welcomed sight, and the afternoon looks rather nice with mostly sunny skies and temperatures in the mid to upper 60s.

SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/
Dry conditions for the local area for the Short Term period. The cold front continues to track to the south and east of the Mid- Atlantic through the weekend, but the tail end of the front will extend back through the Mid-Atlantic and Gulf Coast. High pressure builds over the region for the weekend and start of the new work week. Low pressure develops on that old front and will begin to push the front back north as a warm front, but the system will stay well south of the region, and any rainfall on Sunday will stay south of Delaware.

Chilly temperatures in place. Highs will be in the upper 50s to around 60 on Sunday, and then in the low to mid 60s on Monday. Lows generally in the 30s to low 40s. There may be some patchy frost in the southern Poconos late Saturday night.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
Elongated high pressure along the East Coast slides out to sea Tuesday through Tuesday night. Low pressure approaching from the west will drag a cold front through the region Tuesday night through Wednesday, bringing at least a chance for area-wide showers across the region during that time, though will also carry likely PoPs for areas north and west of the I-95 corridor.

Temperatures moderate to near normal levels ahead of this front with highs generally in the mid and upper 60s. Behind the passage of the cold front, cold air advection will be underway, and highs drop back into the upper 50s and low 60s Thursday before rebounding on Friday.

One thing to look out for is the potential for frost development late Monday night and Tuesday morning, mainly for the southern Poconos and far northwest New Jersey. Lows will drop into the low to mid 30s with light winds and Max RH values around 70 percent. Will carry patchy frost for those areas.

Lows Wednesday night and Thursday night will drop into the 30s for most areas. It is too soon to determine if conditions will promote frost development.

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

Tonight...Mostly MVFR ceilings this evening lowering into the IFR range. Many sites will likely hover closely around the MVFR/IFR range for several hours overnight, but IFR restrictions at times are expected to occur. Rain will generally be light for areas that do see showers, so not expecting much in terms of visibility restrictions. Have higher confidence in reduced visibility at KACY where guidance continues to point at the potential for some marine fog coming onshore in addition to the scattered showers. Winds out of the south/southeast around 5 kt, becoming west/northwesterly late tonight once the cold front moves through. Moderate confidence overall, low confidence on marine fog development.

Saturday...MVFR CIGs to start, lifting to VFR by the late morning as skies clear out. MIV/ACY will be slower to improve.
West/northwest winds around 10 kt with some spots seeing gusts near 20 kt. Moderate confidence overall.

Outlook...

Saturday night through Wednesday...VFR conditions until Tuesday night, then possible sub-VFR conditions in SHRA Tuesday night and Wednesday.

MARINE
A Small Craft Advisory is in effect for all ocean zones through tonight as seas will be around 5 to 6 feet. On the Delaware Bay, no marine headlines are expected. Some marine fog is possible.
Will wait to see how things develop before issuing a Marine Dense Fog Advisory. Periods of showers likely at times for tonight and tomorrow morning.

For tomorrow, no marine headlines expected anywhere as seas will be around 3 to 4 feet and winds out of the west/northwest around 10-20 kt.

Outlook...

Saturday night through Wednesday...Tranquil conditions for most of the new week, then VSBY restrictions in showers Tuesday night and Wednesday. Sub-SCA conditions Saturday night through Tuesday night, and then potential SCA conditions Wednesday.

TIDES/COASTAL FLOODING
Spotty minor tidal flooding was observed within some of the back bay communities of Ocean County, NJ and Sussex County, DE this morning. Some minor tidal flooding remains possible through tomorrow morning around high tide within Barnegat Bay. Tidal flooding is not expected oceanside for any communities.

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