Area Forecast Discussion National Weather Service Mount Holly NJ 927 PM EDT Thu Sep 23 2021

SYNOPSIS. The cold front will continue to push offshore through this evening then stall offshore through this weekend. Meanwhile, high pressure briefly builds into the Mid Atlantic region late Friday into early Saturday. Another weak cold front may move across the area Sunday, followed by a stronger cold front around Tuesday. Meanwhile, high pressure builds across the southeastern states into early next week.

NEAR TERM /THROUGH FRIDAY/. The heaviest rain has exited the region at this time so we've cancelled the Flash Flood Watch.

For tonight, the front will start to move offshore. Latest trends suggest that some additional showers may blossom along the back edge of the front through the overnight hours. These should be lighter and less organized than the rain from today. However, a chance for showers will remain over the eastern half of the area for much of the night. Lows will vary quite a bit. Western and especially northwestern portions of the area will drop to the low 50s (even upper 40s!) as cooler air spills in behind the front. However, with the lingering clouds and showers, eastern areas will be closer to 60.

For Friday, the low pressure system over the Great Lakes will begin to accelerate northeastward into Canada. Light northwest flow will overspread the area and continue to advect in cooler and drier air. There may be some lingering showers near the coast through mid- morning, but most areas will be dry by sunrise. Aside from the chance for a lingering coastal shower early, Friday will turn into a very pleasant and fall like day. Highs only in the upper 60s and low 70s are anticipated, and low dew points will bring a crisp feel to the air. Abundant sunshine is expected.

SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/. Dry weather is expected for the beginning of the weekend from Friday night through Saturday night. High pressure will briefly affect the Mid Atlantic region Friday night through Saturday, before weakening across the area Saturday night. However, a weak disturbance may develop along the weakening frontal boundary that will be stalled offshore of the east coast later Saturday into Saturday night. If this low moves close enough to the coast, it could bring some showers to portions of coastal New Jersey. Otherwise, dry weather is expected during this period.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. The long term forecast is for mostly dry weather, with a couple of chances of showers with a couple of weak cold fronts.

High pressure will build across the southeast states through the weekend into early next week. Meanwhile, a surface trough may be in place across the Mid Atlantic on Sunday, while a weakening cold front moves across the area as well. There is little moisture associated with either of these features, so no precipitation is expected.

By Monday into Tuesday, another weak cold front, yet stronger than the front over the weekend, will approach the area and move across the east coast. The actual front may not make it until Tuesday, but a pre-frontal trough may affect on Monday into Monday night. There will be a chance to slight chance of showers from Monday through Tuesday.

Dry weather is expected to return for Wednesday as the front stalls offshore and high pressure builds across southeastern Canada with our area on the southern periphery.

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

Tonight . There will likely continue to be some fluctuations in cig conditions this evening with most sites at risk for at least occasional MVFR cigs. Expect lower cigs to be a bit more persistent at KABE and especially KACY where MVFR cigs may linger through the night. Winds generally light (in the 3 to 7 knot range) and initially mainly W/SW early this evening becoming NW through the overnight.

Friday . VFR. West-northwest wind 5 to 10 kt, except they may be more west-southwest near RDG and ABE. High confidence.

Outlook .

Friday night-Saturday night . Mostly VFR expected. Northwest winds 5- 10 knots or less Friday night, becoming southwest during the day Saturday, then northwest Saturday night. Moderate confidence.

Sunday-Sunday night . VFR conditions expected. Northwest winds 5-10 knots. Moderate confidence.

Monday-Tuesday . Generally VFR conditions expected. A chance of showers which may temporarily lead to lower conditions. Southwest winds 5-10 knots with gusts 15-20 knots on Monday, becoming west during the day Tuesday behind a cold front. Moderate confidence.

MARINE. Through tonight . A Small Craft Advisory is in effect on the Atlantic coastal waters, where seas will remain around 5 to 7 ft. Ahead of the cold front, south-southeasterly winds could continue to gust around 30 kt through the evening. Behind the front, winds will shift to southwest then northwest and decrease in speed. The wind shift will happen over the southern waters first, as early as this afternoon, but should occur over all the coastal waters by around midnight. On Delaware Bay, with the shift to westerly flow, wind speeds have decreased significantly. The Gale Warning for Delaware Bay has been cancelled, and sub-SCA conditions are expected.

Friday . On the Atlantic coastal waters, seas will continue to run around 5 ft into the afternoon. The SCA will remain in effect until 4PM, though it is possible we will be able to cancel it a little earlier than that. On Delaware Bay, sub-SCA conditions are expected. Northwest wind 10 to 15 kt, decreasing and turning more westerly in the afternoon.

Outlook .

Friday night-Sunday . Winds and seas are expected to remain below advisory levels through the period, although winds could gust around 20 knots at times and seas could approach 4 feet at times.

Rip currents .

A HIGH risk for rip currents will continue for the NJ beaches on Friday with a MODERATE risk expected at the DE beaches. A Rip Current Statement is in effect through Friday for the NJ beaches.

Seas will continue to subside into Saturday with a MODERATE risk for rip currents expected for both the DE and NJ beaches.

TIDES/COASTAL FLOODING. The strong southeast to south flow has ceased on Chesapeake Bay and on Delaware Bay. Water is no longer being pushed into the bays.

While the surface flow has shifted mainly to the west on the Chesapeake, it may take some time for the excess water to drain out of the bay. While widespread minor tidal flooding is not expected with this evening's high tide on the upper eastern shore, some spotty overflow remains possible at that time. It should not be impactful enough to warrant another advisory.

The minor tidal flooding has come to an end in Salem County, New Jersey and in New Castle, County, Delaware. The Coastal Flood Advisory has been allowed to expire there. Some excess water remains trapped in the tidal Delaware River. Widespread minor tidal flooding is expected there into this evening. The flooding will be enhanced a bit by runoff from the heavy rain. As a result, a Coastal Flood Advisory remains in effect for the tidal Delaware River down to the Commodore Barry Bridge area until 7:00 PM.

Finally, no significant issues are anticipated along the oceanfront and along much of Delaware Bay. However, some spotty minor tidal flooding is possible on the back bays into this evening.

Tidal departures will continue to decrease on Friday and into the weekend.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . High Rip Current Risk through Friday evening for NJZ014- 024>026. DE . None. MD . None. MARINE . Small Craft Advisory until 4 PM EDT Friday for ANZ450>455.
