Area Forecast Discussion National Weather Service Mount Holly NJ 613 PM EDT Wed May 15 2024
SYNOPSIS
An area of low pressure will remain offshore of the Mid Atlantic coast through Friday, before drifting out to sea. High pressure tries to build down into the area from the northeast over the weekend, but never fully makes it into the area before another area of low pressure moves across the central Appalachians and offshore of the North Carolina coast later Sunday into Sunday night. Weak high pressure may finally build across the area early next week, before a cold front moves across the east coast by mid week.
NEAR TERM /THROUGH THURSDAY/
As of 6:10PM...Occluding surface low pressure remains centered just offshore of Delmarva and southern NJ. Light rain and drizzle continues for areas across the region along with some light patchy fog.
The occluding surface low pressure just offshore of the region this evening will stall through tonight and into Thursday.
Chances for precipitation will diminish slightly with time tonight as the low nudges just a little to the east/northeast, but overall things will basically stay the same. Expect overcast skies tonight with areas in NJ and near the coast seeing continued drizzle or light rain. Some areas may see some patchy fog into Thursday morning, but any widespread dense fog is not expected.
For Thursday, not a lot of change is expected as the low will be drifting out to sea but only very slowly. This will keep it mainly cloudy with breezy north to northeast winds and some spotty light rain and showers around, once again, especially in NJ and near the coast. Western parts of the forecast area from around Berks County northward into the Lehigh Valley should see a mostly dry day. Expect highs mostly in the 60s (near 60 at the coast) except some low 70s possible in our western zones from Chester and north through Berks Counties and then into parts of the Lehigh Valley.
SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY/
Low pressure remains pinwheeling offshore of the Mid Atlantic coast Thursday night through Friday, before finally moving out to sea Friday night. There might be a few lingering showers near the New Jersey coast early Thursday night, but the forecast dries out for Friday as high pressure tries to begin nosing down into the area from the northeast. Most of Friday night should remain dry as well, except possibly late in the overnight showers may begin to move in from the west.
LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/
Unsettled weather can be expected for portions of the area this weekend, especially for the southern third of the area from southern New Jersey, Delaware, and eastern Maryland. As an area of low pressure will move across the central Appalachians, then offshore of the North Carolina coast Saturday into Sunday, a warm front will lift northward, but remain south of the area.
However, there will be enough moisture and lift across the area for periods of showers to develop across the southern areas.
High pressure tries to build down from the north, but never fully sets in, but it may have enough effect on the area to keep the weather mostly dry for the northern portions area; however, there will remain a chance of showers even for northern areas given the proximity of the low and front to the south.
By early next week, the low pressure to the south will begin to drift out to sea, while high pressure briefly affects the Mid Atlantic region. Dry weather is expected Monday into Tuesday. As we move into next Wednesday, a cold front is forecast to move into the eastern seaboard, bringing an increase in shower chances.
AVIATION /22Z WEDNESDAY THROUGH MONDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas...
This afternoon...Mainly MVFR cigs and VFR visbys this afternoon with low stratus and some spotty light rain and drizzle around. Exception is ACY where it should stay mainly IFR or LIFR. Northeast winds 10 to 15 gusting up to 20 knots except 15 to 20 gusting up to 30 knots at ACY. Moderate confidence.
Tonight...Continuing sub VFR with IFR cigs likely to redevelop this evening for the I-95 TAF sites and points south and east towards the coast. Some improvement back to MVFR then possible overnight around ILG, PHL, and PNE. Some lingering spotty light rain, drizzle and mist/fog around, especially around ACY. Northeast 10 to 15 knots backing to northerly overnight. Moderate confidence.
Thursday....Sub VFR cigs continue with only very gradual improvement into the afternoon from west to east. Most sites should be mainly at MVFR except IFR near MIV and especially ACY. North to northeast winds 10 to 15 knots with some gusts to around 20 knots. Moderate confidence.

Thursday night...IFR then MVFR conditions expected with a chance of showers.
Friday-Saturday...VFR conditions expected.
