Area Forecast Discussion National Weather Service Mount Holly NJ 933 PM EDT Wed Aug 4 2021

SYNOPSIS. The front which has been nearly stationary off our coast the last two days will drift northwest as it dissipates. High pressure will build over our region through the end of the week. A weak cold front may approach the region Sunday night. A trough may move over the region mid week next week.

NEAR TERM /THROUGH THURSDAY/. Showers have thus far stayed mostly off shore. Although the front should drift northwest overnight, it should also be weakening at the same time, so the window of potential for showers along the coast is shrinking. Given current trends, have decreased PoPs for most locations, except the immediate coast.

By tomorrow, expect the front to be mostly dissipated, and along with it, any showers near our region. Additionally, the upper level jet which has been responsible for persistent high clouds since yesterday will shift east, resulting in clearing skies. The clearing skies will allow for a modest warming trend into tomorrow, with highs mostly in the 80s across the region (70s forecast for the southern Poconos and immediate coast).

SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/. A weak warm front may lift through the region late in the week as low level southerly return flow develops. Consequently, the main story through this period will be warmer and humid conditions returning to the region. An approaching mid level short wave trough could result in some showers and thunderstorms during the day on Saturday, but otherwise, don't expect any precipitation chances through this period.

Highs both Friday and Saturday should be in the upper 80s to near 90 for much of the region (with the exception of the immediate coast and the southern Poconos which may see highs in the lower 80s). Although temperatures may be a degree or two lower on Saturday as compared to Friday thanks to the increasing cloud cover with the approaching trough, it won't feel much better as by Saturday dew points could be nudging into the upper 60s and lower 70s.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/. If you are a fan of summer, then have no fear. Summer makes a return to our area over the weekend and into early next week.

The upper trough swings offshore by late Saturday night which should lead to some ridging across the Mid-Atlantic. At the surface, Bermuda high pressure sets up shop and puts us into a more summer- like regime. With southwest flow at the surface and up through the lower levels of the atmosphere, we will see both an increase in temperatures and dew points, leading to a bit more steamy airmass across the region. 850mb temps will rise into the upper teens to around 20 C through the first half of the week. This will translate into high temperatures back into lower 90s with some spots near or into the mid 90s by midweek. The kicker will be that the dew points will rise back into the lower to mid 70s as we progress through the week and this may allow for heat index values in the upper 90s to lower 100s for Monday through Wednesday. Heat headlines may be needed so this time frame will need to be closely monitored.

With any good potential heat wave, we will also will see the typically occurrence of diurnally driven showers and thunderstorms each day, but moreso towards midweek as a trough sets up across the region and instability increases.

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

Through Tonight: Predominantly VFR however MVFR ceilings may encroach on KACY and KMIV at times. Winds will remain light at 5-10 knots out of NE/ENE through 03Z, at which time the surface low offshore begins to lift northward and shifts winds to out of the N and eventually NNW at 5-10 knots by tomorrow morning. High confidence on most aspects of the forecast, but low confidence on the exact timing for MVFR conditions at KACY and KMIV.

Tomorrow: VFR conditions expected. High clouds should clear out by 15Z. Light (near or below 5 kt) winds generally out of the north or northwest. High confidence.

Outlook .

Friday: VFR conditions expected for the period. Winds starting light and variable becoming southwesterly less than 10 kt by Friday afternoon. Moderate confidence.

Saturday: Predominantly VFR with a chance of MVFR as showers and thunderstorms approach from the South along a warm front, increasing cloud cover. Winds light and out of the SSE at 5-10 knots. Moderate confidence.

Sunday and Monday . Mainly VFR conditions expected. Showers and thunderstorms possible during the afternoon and evening, mainly north and west of KPHL. West to southwest winds less than 10 knots on Sunday, becoming more southerly on Monday. Moderate confidence.

MARINE. SCA conditions, primarily for elevated seas are expected to continue through most, if not all, of Thursday. Winds are expected to become light and shift to southeasterly during the day on Thursday.

On the Delaware Bay, winds and waves should stay below SCA criteria.

Outlook .

Thursday night through Monday . Once seas drop below 5 ft (if they haven't already by Thursday evening) winds and seas should stay below SCA criteria.

Rip Currents .

A moderate risk for the formation of dangerous rip currents is expected to continue through Thursday due to elevated wave heights and some onshore flow. By Friday, winds should shift to S/SE which will continue to bring an onshore component to the NJ coast but not as much for DE. As a result, we'll carry a moderate risk for rip currents for the NJ shore for Friday with a low risk for the DE shore.
