Area Forecast Discussion National Weather Service Mount Holly NJ 154 PM EDT Thu Jun 13 2024

SYNOPSIS
Weak surface high pressure centered offshore will still remain in control through tonight. A cold front crosses our region Friday afternoon into Friday night. High pressure then builds in over the region and continues into the beginning of next week.

NEAR TERM /THROUGH FRIDAY NIGHT/
A closed low centered across Hudson Bay Canada will gradually shift eastward tonight and especially Friday and Friday night. One of the shortwaves embedded with this trough should amplify some Friday from the Great Lakes into the Northeast. This system will drive a cold front across our area Friday afternoon and evening. Meanwhile, weak surface high pressure centered offshore but extending across our area this afternoon will shift farther away tonight into Friday.
Increased low-level moisture from south to north has resulted in a decent amount of cumulus this afternoon. This is expected to dwindle through the evening with the loss of daytime heating. Sea and bay breezes will also keep temperatures lower closer to the coasts into this evening, and the KDOX radar shows a narrow convergence boundary across Delaware due to flow off the Delaware Bay running into a more south to southwest wind to its west.

A weak shortwave trough is forecast to arrive from the west late this afternoon and this evening. Some guidance, especially the high- resolution ones, show some isolated showers mainly across our western zones that develop off the higher terrain into this evening and again overnight. The forcing is rather weak with this system and the probability of precipitation is so low and therefore opted to keep the forecast dry. An isolated shower however still cannot be ruled out. Temperatures will drop back into the 60s for most areas.

As we go through Friday, an upper-level trough is forecast to arrive in the afternoon and evening. While the parent trough is farther north, the southern portion of it has stronger shortwave energy and is timed during peak heating across our region. At the surface, a cold front will work its way across our region from west to east during the afternoon and evening. Since the stronger winds look to lag to the west of the cold front, the flow is strongest in the upper levels with it weakening in the mid to lower levels, and this all decreases especially in the lower levels the farther south and east across our area. As a result, the stronger shear is positioned across our northern and western zones. There is ample instability forecast to be in place (MLCAPE up to 1500 J/Kg) given air temperatures forecast to be in the 80s with even some lower 90s and dew points in the 60s. The model forecast soundings show a well mixed and warm boundary layer in the afternoon and early evening.
This results in an inverted-V profile in the lower levels and thus increasing the downdraft instability (DCAPE).

Given the flow profiles and incoming frontal forcing, convection is forecast to develop to our northwest and west and then propagate east and southeastward during the afternoon and evening. While coverage and timing does vary some among the guidance suite, convection should organize into clusters or a broken line as it shifts into and across our area, with this possibly weakening near and especially south and east of I-95. This will depend on the timing as southerly flow ahead of the convection and front will bring some marine influence into portions of the coastal plain.
Given convection in a cluster or linear mode, locally damaging winds are the main threat especially with stronger cores aloft enhancing the downburst potential. Freezing levels look on the higher side, however some hail cannot be ruled out with some stronger convective cores. The precipitable water values are forecast to be approaching 2 inches for a time ahead of the cold front, and therefore high rainfall rates should occur with the strongest convection for a time. The flash flooding risk however looks to be low, with this potentially the most focused across northern New Jersey.

The convection looks to be shifting offshore or weakening during the evening hours with the severe thunderstorm risk ending. Some drier air then starts to arrive from the northwest in the wake of the cold front by later Friday night with at least some partial clearing also starting to arrive.

SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/
High pressure builds in from the north and west on Saturday, ushering a rather tranquil weekend. Highs during the afternoon will be in the low-to-mid 80s with nighttime lows dipping into the mid 50s to right around 60.

LONG TERM /SUNDAY THROUGH WEDNESDAY/
Behind the cold front the synoptic pattern sets up with a building ridge through the weekend. Heights will quickly rise across the Mid Atlantic with a mid level ridge dominating through at least the early portion of next week. While the surface high will start to push offshore, all that does is setup southerly return flow leading to warm temperatures being advected north for several days in a row. While global guidance is still rather spread out with just how hot it will get across the region next week, guidance across the board has been fairly consistent with the building high pressure and increasing heat through the week with a high likelihood of temperatures lingering well into the 90s for a number of days. At this point, it is certainly not too early to start thinking about your cooling options for next week. For anyone hoping for temporary relief from precipitation chances, at the moment, chance for this remain rather low. While there are some pieces of shortwave energy tracking through the region during the week, the overall chance for showers is fairly capped (10-15%) due to the very weak forcing from these shortwaves. At this point, a large number of ensembles show the ridge starting to deamplify but still holding on till late in the week. This would allow for some weakening in max temps during the day but not much.

AVIATION /18Z THURSDAY THROUGH TUESDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Rest of this afternoon...VFR. South to southwest winds around 10 knots (south-southeast winds for a time at KACY and KILG). Some local gusts to 20 knots possible for a time, especially at KACY.
Moderate confidence.

Tonight...VFR. South-southwest winds diminishing to near 5 knots, with it becoming light and variable at some terminals. Moderate confidence.

Friday...VFR for much of the time, however some times of sub-VFR conditions later in the afternoon and evening as some showers and thunderstorms move through with a cold front. South to southwest winds around 10 knots, becoming west later in the afternoon at KRDG and KABE. Low confidence on the timing details.

Outlook...

Saturday through Monday...VFR.

MARINE
Through Friday, the conditions are anticipated to remain below Small Craft Advisory criteria. Southerly winds should be the strongest at times across the northern New Jersey coastal waters and possibly up Delaware Bay. However, given much warmer air moving over the cooler waters, mixing should be more limited and since it looks marginal opted to keep the conditions below advisory criteria. Some showers and thunderstorms should arrive late Friday afternoon and Friday night, and some storms could produce locally gusty winds.

Outlook...

Saturday through Monday...No marine headlines expected. Winds up to 10-15 kts with seas 2-4 feet. Fair weather.

Rip Currents...

Southwest flow 5-10 mph becomes south 10-15 mph with occasional gusts up to 20 mph today. Breaking waves will average 1 to 2 feet. Primarily a 1-2 ft 7-8 second short period swell from the E-SE. As a result, there is a LOW risk for the development of dangerous rip currents today.

On Friday, south winds increase to around 15 mph with 20 to 25 mph gusts. The flow will be a bit more onshore for most of New Jersey as opposed to northern New Jersey and Delaware. That said, strongest winds will be across northern New Jersey.
Additionally, guidance shows a 1 ft 9-10 second longer period swell from the SE to SSE developing by the afternoon. As a result, there is a MODERATE risk for the development of dangerous rip currents for New Jersey beaches where the coastline is more perpendicular or oblique to the longer period swell. LOW risk for the development of dangerous rip currents for the Delaware beaches. Breaking waves will once again average 1 to 2 feet.
