Area Forecast Discussion National Weather Service Mount Holly NJ 1216 PM EDT Fri Jun 21 2024

Bermuda high pressure remains in control through much of the weekend. A back door cold front will move in from the north on Friday and will stall over the area into Saturday before returning north as a warm front. A stronger cold front will approach the region Sunday looking to pass through Monday. High pressure returns for Tuesday, followed by another front for the middle of next week.

As of 12:15PM...No major changes to the forecast at this time.
Previous discussion remains below.

The beat goes on with the heat continuing for the end of the week. Temperatures will yet again be a touch higher with ambient temperatures in the low to mid 90s and heat indices pushing triple digits. The Heat Advisory that has been in effect for the past several days remains in effect for counties north of a line from Wilmington to LBI. However, not expecting any records to fall as we have some impressive daily records for June 21st (see climate section below for more info). The only climate site with a remote chance is Trenton as it is the only location with a forecasted high within 3 degrees of the record.

In addition to the heat, there is a small threat for severe weather, mainly north of I-78 as a cold front sags down from the north. Overall, the severe threat looks rather limited due to a lack of shear. Most of the CAM guidance shows 0-3km shear values less than 30 kt. The HRRR ensemble shows 60-70% chance of SBCAPE values exceeding 1000 J/kg though north of I-78, so there is ample instability in place even with the lack of the shear. What this all means is that thunderstorms will be scattered in nature, with a few storms capable of producing some stronger downbursts which could lead to damaging wind gusts.
However, given the lack of shear, any severe thunderstorms will be relatively isolated, and thinking the bigger threat will be north and west of the area where the better instability and shear are. In terms of timing, the window for any severe storms looks to be between 3-10 PM, though some showers/sub- severe thunderstorms could linger into the night in northern NJ. With weak flow aloft, any thunderstorms that do develop will be relatively slow moving, so cannot rule out a quick inch or two in some spots leading to poor drainage flooding. SPC has a MARGINAL risk (1/5), which is about right. South of the I-78 corridor, it should stay dry and hot.

We will not get much relief tonight as temperatures will only get down into the low to mid 70s. Though, compared to the next couple nights, this will seem cool. Showers in northern NJ slowly dissipate as the night goes on. Some patchy fog is possible, especially in areas that see rain this afternoon and evening as well as in more rural/sheltered areas such as the NJ Pinelands.

The heat and humidity continue to build into the region this weekend with the most oppressive conditions of this heat wave so far.

Back door cold front will be just over the Fall Line Saturday morning and returns back north as a warm front on Saturday.
South to southwest flow will prevail, and an even warmer and more humid air mass spreads into the Northeast and Mid-Atlantic.
Highs on Saturday rise into the mid and upper 90s for most of the region, and in the upper 80s to low 90s in the southern Poconos and northern New Jersey. Meanwhile, surface dew points rise into the lower 70s in the morning, but look to mix down into the upper 60s Saturday afternoon. This will yield max heat index values in the upper 90s to low 100s. Current forecast has max heat index values just under 105 for interior portions of New Jersey. Plans for heat headlines is to convert the Excessive Heat Watch to a Heat Advisory for portions of southeast Pennsylvania and New Jersey. Will keep the Excessive Heat Watch in effect for the urban corridor which includes eastern Chester and New Castle counties north to Middlesex and Somerset counties. This also includes Salem county, which, although not technically part of the urban corridor counties, may touch a max heat index of 105. It is close enough that those counties may be converted to Excessive Heat Warnings, especially considering the cumulative effects of the heat over the last week even if max heat index values remain below 105. For the coastal strip of New Jersey, southeast New Jersey, the eastern shores of Maryland, and Kent and Sussex counties in Delaware, max heat index values look to remain below 105, so will not hoist a Heat Advisory in those counties for Saturday. There are currently no Excessive Heat Watches for those counties for Saturday.

With the front north of the area, a thermal trough develops over central Pennsylvania. Some shortwave energy approaches from the west and passes through the region Saturday afternoon. This will interact with the front just north of the area and will spark off scattered afternoon and evening showers and thunderstorms, mainly for areas north and west of the I-95 corridor. For areas north of I-80, showers and thunderstorms may become likely. SB CAPE values will be 2000 to 2500 J/kg, and PWATs will be around 2 inches. DCAPE values will even be around 1000 J/kg. The limiting factor may be shear, as 0-6 km Bulk Shear could get up to 25 kt or so late in the day. Heavy rain, gusty winds, and frequent lightning can be expected in the stronger storms. The Storm Prediction Center has a Marginal Risk (1 out of 5) for the southern Poconos, northern New Jersey, and Lehigh Valley, mainly areas north of I-78.

Disgustingly warm and humid Saturday night. Lows generally in the 70s, though not much below 80 in/around the I-95 corridor, including Philadelphia and Delmarva.

Sunday looks to be the hottest and most humid day of this stretch, however, there are some factors that may limit the worst conditions from developing. Bermuda high pressure remains anchored offshore and a cold front approaches from the west.
Southwest flow increases over the area, ushering hot and humid air into the region. Forecast high temperatures will get into the upper 90s for urbanized areas of southeast Pennsylvania, most of southern New Jersey, and Delmarva, and in the mid 90s or so for the areas north of the Fall Line. The southern Poconos and northern New Jersey areas will be in the upper 80s to low 90s. Surface dew points will be in the lower 70s. Should the highest temps be realized with these dew points, then widespread max heat index values will range from 100 to 110. Will keep the Excessive Heat Watch in effect for the entire region for Sunday.

Should clouds associated with that cold front move into the region in the afternoon, any increased cloud cover would preclude the highest temperatures from occurring. In addition, timing of convection will also have a major impact on if those highest temperatures can be realized. For now, will keep the Excessive Heat Watch in effect for the entire forecast area for Sunday.

Back to that cold front. There are concerns about the timing of the front. 00Z/21 NAM has convection firing up ahead of the front on a pre-frontal trough late Sunday afternoon and moves through Sunday night. The front itself does not move through until late Sunday night. This signal is also showing up on the 00Z/21 GFS, however, the development of convection on that pre- frontal trough develops earlier in the day compared to the NAM.
00Z/21 RGEM and ECMWF also showing something similar, though QPF not as intense as NAM and GFS.

Should storms fire up in the afternoon, that would keep the highest temperatures from developing, and and that would keep instability levels down, potentially keeping the strongest storms from developing.

Overall, will stick with the high temperature forecast in the upper 90s. Will carry mostly chance PoPs for Sunday afternoon, increasing to likely PoPs Sunday night. Will also mention potential for gusty winds, heavy rain, and frequent lightning.
SB CAPE values will be up around 2500 J/kg, along with 1000 to 1500 J/kg DCAPE. 0-6 km Bulk Shear will be 20 to 25 kt through the afternoon, but rising to 30 to 35 kt Sunday evening as that front edges closer. Main concern for timing of the strongest storms will be from 18Z Sunday to 06Z Monday. Showers and thunderstorms continue through the night as the cold front slowly passes through the region.

Cold front continues to work its way through the region on Monday, but the relatively cooler and drier are does not make its way through the region until Monday afternoon. Surface dew points will be in the low 70s in the morning, lowering to the 60s late in the day. Highs will be in the upper 80s to low 90s with max heat index values in the mid 90s in southern New Jersey and Delmarva. Lingering showers and thunderstorms will pass through the region with the passage of that front.

High pressure builds into the region Tuesday with dry conditions and highs in the upper 80s to low 90s with, compared to this weekend, low humidity as surface dew points will be in the low 60s.

A series of frontal boundaries are possible Wednesday and Thursday with scattered showers and thunderstorms. Temperatures look to rise back well into the 90s with possible heat headlines on Wednesday before returning to the 80s on Thursday.

The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today...Primarily VFR. Scattered showers and thunderstorms possible north of I-78 may affect KABE and bring brief restrictions, but the probability of that is low (only around 30%), so have kept prevailing VFR for the entire TAF period.
Quiet elsewhere with winds out of the southwest around 5-10 kt.
Winds more southerly at KACY/KMIV with the sea-breeze and at KILG with the bay-breeze. Moderate confidence.

Tonight...Primarily VFR, though some patchy fog possible at KRDG/KABE/KACY/KMIV. Probabilities are low however, only around 15-20%, and prevailing VFR was kept with the 12z TAF package.
South/southwest winds around 5 kt or less. Moderate confidence.


Saturday through Saturday night...Generally VFR.
Afternoon/evening SHRA/TSRA could result in brief sub-VFR conditions. VSBY restrictions in fog possible at night.

Sunday through Sunday night...VFR during the day, then sub-VFR in SHRA/TSRA in the afternoon and at night.

Monday...Mainly VFR, but scattered SHRA/TSRA with sub-VFR conditions from time to time. VFR at night.


No marine headlines expected through tonight. South/southwest winds 10-20 kt and seas 2 to 4 feet.


Saturday...Generally sub-SCA conditions, however, sustained 15 to 20 kt winds will develop on the ocean waters.

Saturday night through Sunday night...SCA conditions likely with 25 to 30 kt gusts, especially on the ocean waters.

Monday through Tuesday...Sub-SCA conditions.

Rip Currents...

Today...Southerly winds around 10-15 mph and breaking waves around 2-3 feet. Portions of the southern NJ coast will keep an onshore component of the wind, in addition to the occurrence of the Full Moon. For this reason, have maintained a MODERATE Risk for all New Jersey beaches except Monmouth County. For the Delaware Beaches and Monmouth County, maintained the LOW Risk of dangerous rip currents.

Saturday...Similar weather conditions are expected on Saturday.
With this in mind, saw no reason to change Rip Risks for NJ/DE beaches from what is currently posted for today.

Rip currents occur often in the vicinities of jetties and piers. Utilize any guarded beaches if venturing out into the water. For specific beach forecasts, visit weather.gov/beach/phi

Record high temperatures for today. Trenton is the only site currently forecast to be within 3 degrees of their record. As a result, not really expecting any records to fall today. No daily record high minimum temperatures will be set for today as temperatures this morning have all fallen below the record high minimums.
