Area Forecast Discussion National Weather Service Mount Holly NJ 141 AM EDT Sun Jun 23 2024

SYNOPSIS
High pressure remains anchored offshore through Sunday. A cold front comes through later Sunday, moving offshore by Monday morning. High pressure settles in for the early part of the week before another cold front moves in for the middle of the week.
High pressure returns for the end of next week.

NEAR TERM /THROUGH TODAY/
As of 130 AM...A few lingering thunderstorms across the I-80 corridor continue to push ENE across the northern tier.
Convection should fizzle out within the next few hours before daybreak arrives.

Otherwise, temperatures will only cool off tonight into the low to mid 70s with upper 70s across the urban corridor and Delmarva.
Meanwhile, dew points will remain in the 70s as well, keeping it muggy tonight.

Oppressively hot and humid conditions remain for Sunday. Excessive Heat Warnings were posted earlier for the urban corridor and parts of the NJ Coastal Plain as heat indices of 105-110 are expected.
These conditions combined with the nearly week long stretch of heat, are going to result in dangerous conditions outside for Sunday as the effects of heat stress on the body can be cumulative. Time outside should be limited and if you are out and about, drink plenty of water!

With such a hot and humid airmass in place, and an approaching cold front, there will be the chance for some severe weather. Lift will be aided with a shortwave and pre-frontal trough coming into a moist and unstable airmass. Deep layer shear of 30-40 kt and moderate instability (1000-2000 J/kg of SBCAPE) will support the development of thunderstorms capable of producing damaging wind gusts. The SPC has updated the Day2 outlook to place much of our CWA in a Slight risk (N/W) and Marginal risk for the shore and most of our Delmarva area. The limiting factor is the better shear will be located further north but still think there is sufficient shear to support some strong to severe thunderstorms. Not overly concerned with the flooding potential at the moment as storm motion should be steady, though with PWATs pushing 2 inches, any thunderstorms will produce heavy rain capable of dropping an inch or two of rain quickly.

SHORT TERM /TONIGHT THROUGH TUESDAY/
The cold front comes through on Sunday Night/Monday morning, knocking down dew points a good 15 degrees or so. It will feel much more comfortable on Monday with dew points back into the 50s and temperatures getting into the mid to upper 80s. Monday looks unsettled though as a series of shortwaves rotate around the base of the trough passing by to the north. This will result in a some scattered showers and thunderstorms, though the severe potential looks much lower compared to Sunday. Any showers/thunderstorms will dissipate after sunset, and it should be a quiet night overall as high pressure moves in. Temperatures on Monday Night will get down into the 60s.
Tuesday is expected to be dry and hot as a short wave ridge traverses the region. Temperatures are forecast to climb back into the 90s.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
Overview: Above normal temperatures will continue for the long- term, however most of the week with the exception of Wednesday will not be as oppressive as the heat this weekend.

High temperatures through most of the extended look to be in the upper 80s/low 90s. The exception being Wednesday, as high pressure moves offshore resulting in a southerly flow and warm air advection. For much of the region, this will lead to widespread 90s (with the exception of the higher terrain in the Poconos and NW NJ and the immediate coast). May need a Heat Advisory for some areas (especially the urban corridor), but want to get through the current heat event before moving on to Wednesday.

The main rain chances are Wednesday into Thursday as a cold front approaches and again late in the week (at this point looks like Saturday or later) as another cold front starts to approach.
Unlike the Sunday event, flooding looks like it could be more of a concern with the Wednesday system as the front looks to be a little on the slower side, and we will have a very warm and moist airmass in place. With such a warm and moist airmass in place, cannot rule out some stronger thunderstorms as well especially a downburst/strong wind potential.

AVIATION /06Z SUNDAY THROUGH THURSDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Rest of tonight (through 12Z)...VFR, however some localized fog possible late. Southwest winds 5-10 knots, becoming locally light and variable. Winds will become north or northeast 5-10 knots for some terminals where an outflow boundary moves through. Low confidence on the details.

Sunday...Some showers and thunderstorms in the afternoon will result in times of local sub-VFR conditions and gusty winds. Southwest winds increasing to 10-15 knots with gusts 20-25 knots. Moderate confidence.

Outlook...

Sunday night...Restrictions likely with showers and thunderstorms (60-80%).

Monday...Mainly VFR. Restrictions possible with a chance of showers/thunderstorms (30-40%) the first half of the day.

Monday night...VFR.

Tuesday...VFR.

Wednesday into Thursday...Sub-VFR conditions possible (40-50%)
in the afternoon and overnight with showers and thunderstorms.

MARINE
No headlines expected through tonight. Seas 3 feet will begin to build into early Sunday morning. For Sunday, a SCA goes into effect at 8 AM as winds and seas will build to the low-end of SCA criteria.
Some showers/storms develop late in the afternoon and continue Sunday night.

Outlook...

Sunday night...SCA conditions are expected on the ocean waters. S to SW winds gusting up to 25 to 30 kts. Seas 4 to 7 ft. Showers and thunderstorms likely.

Monday...Winds are expected to relax, but a residual swell will remain. SCA conditions are possible. W winds 10 to 15 kts with gusts up to 20 kts. Seas 4 to 5 ft. A chance of showers and thunderstorms.

Monday night...NW winds 5 to 10 kts. Seas 3 to 4 ft.

Tuesday...W winds 5 to 10 kts, becoming S in the afternoon. Seas 2 to 3 ft.

Wednesday...No marine headlines expected.

Wednesday night into Thursday...Wave heights may get close to 5 feet and gusts close to 25 kt on the Atlantic Coastal Waters.

Rip Currents...

Sunday...With south winds 15 to 25 mph, breaking waves in the 3 to 5 foot range, and a 5 to 7 second wave period, we are running with a HIGH risk for the development of rip currents for Cape May/Atlantic/Ocean County and a MODERATE risk for Monmouth and Sussex, DE beaches. Low tide is mainly in the mid afternoon.

Monday...Winds relax a bit and back offshore, but wave periods are forecast to increase. This said, with west winds 10 to 15 mph (maybe some gusts up to 20 mph across the northern beaches), breaking waves in the 2 to 4 feet range, and a 6 to 8 second wave period, we are running with a HIGH risk for the development of rip currents everywhere. Low tide is mainly in the mid to late afternoon.
