Area Forecast Discussion National Weather Service Mount Holly NJ 316 PM EDT Tue Sep 22 2020

SYNOPSIS. High pressure will remain near the Ohio and Tennessee Valleys through Wednesday as Tropical Cyclone Teddy moves through portions of Atlantic Canada while becoming post-tropical. High pressure then slowly drifts off the southeast coast later this week into this coming weekend. A cold front looks to move through from west to east sometime late Sunday or Monday.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. High pressure remains over the Tennessee Valley and Mid- Atlantic tonight as Hurricane Teddy weakens as it moves into the Canadian Maritimes.

Gusty northwest winds will diminish later this evening with loss of diurnal heating. 850 mb temps will be rising through the overnight, so not expecting as cold of a night as it has been of late.

Lows tonight will be in the 40s to low 50s.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/. High pressure slowly slides off the Southeast coast on Wednesday. Incoming smoke aloft may partially obscure the sun, but overall, expecting a mostly sunny day. With WAA continuing, temperatures return to normal levels, with highs generally topping off in the mid to upper 70s, and some spots along the urban corridor may touch 80.

Mixing will be better Wednesday afternoon, so expecting west to northwest winds to increase to around 15 mph with 20-25 mph gusts.

LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/. Surface high pressure will move off the southeast coast Wednesday night through Thursday but will continue to influence the region with mostly benign weather through most of Saturday. After Saturday, moisture associated with Beta's remnants may approach from the south providing the chance of rain showers over the forecast area, especially south of the Mason- Dixon line Saturday night and Sunday. A cold front and associated upper trough look to approach from the west late Sunday or Monday providing additional chances for showers and possibly even some thunderstorms Sunday afternoon into Sunday evening. Chances for showers could last into Tuesday as a secondary cold front moves through. So all in all, becoming a bit more unsettled late in the weekend into early next week.

Temperatures are expected to remain above average through most of the period, cooling to near normal early next week.

AVIATION /19Z TUESDAY THROUGH SUNDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Through this evening . VFR. W-NW winds 10-15 kt with gusts up to 20 kt. High confidence.

Tonight . VFR. W winds less than 10 kt. High confidence.

Wednesday . VFR. W-NW winds increasing to 10-15 kt with gusts up to 20 kt in the afternoon. High confidence.

Outlook .

Wednesday night through Saturday . VFR. Winds generally south/southwest at 5 to 10 knots or less. High forecast confidence through Friday, moderate forecast confidence Saturday.

Saturday night through Sunday . Sub VFR conditions possible at times as showers and low clouds could affect the region. Low confidence.

MARINE. For the Atlantic waters, seas of 7 to 10 feet will diminish through the overnight hours, down to 4-6 feet by Wednesday morning, and then seas may subside to less than 5 feet late in the day. W-NW winds gusting to 20 kt through this evening, then diminishing to around 15 kt tonight. Gusts to 20 kt possible once again on Wednesday.

For Delaware Bay, mainly sub-advisory conditions expected. Winds generally northwest 10 to 20 kt through tonight. There may be some channeling effects in the lower mouth of the bay, which may produce gusts approaching advisory levels. For now, confidence is too low for an advisory.

Outlook .

Sub-SCA conditions are expected Wednesday night through the weekend with fair weather for most of this period. The next chance of showers arrives late Saturday or on Sunday.

Rip currents .

The rip-current risk remains high through Wednesday, as very long-period swell with breaking waves 5 to 8 feet continues today. Swell should diminish somewhat on Wednesday, but will likely remain well above 3 feet with long periods continuing. With winds becoming offshore today, dangerous breaking waves of higher frequency will likely occur through this afternoon. Consequently, high surf will remain a significant threat. The High Surf Advisory remains in effect through early this evening.

TIDES/COASTAL FLOODING. Some lingering spotty minor flooding remains possible in the coastal counties of New Jersey and Delaware with the afternoon high tides today and Wednesday Wednesday. However, it is not expected to be widespread enough to warrant an advisory.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . High Rip Current Risk through Wednesday evening for NJZ014- 024>026. High Surf Advisory until 7 PM EDT this evening for NJZ014- 024>026. DE . High Rip Current Risk through Wednesday evening for DEZ004. High Surf Advisory until 7 PM EDT this evening for DEZ004. MD . None. MARINE . Small Craft Advisory until 8 PM EDT Wednesday for ANZ450>455.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
