Area Forecast Discussion National Weather Service Mount Holly NJ 955 PM EDT Mon Sep 21 2020

SYNOPSIS. High pressure over the Northeast will retrograde back towards the Ohio and Tennessee Valleys on Tuesday as Hurricane Teddy approaches the Canadian Maritimes. High pressure then slowly drifts off the Southeast Coast later this week. A weak cold front passes through the region on Friday. High pressure returns for the weekend, but low pressure may develop over the Southeast and Mid-Atlantic by the start of next week.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Quiet conditions remain across the area as high pressure will control the weather through the night. Mostly clear skies will allow good radiational cooling to take place, but temperatures should remain warm enough to preclude much frost from forming, except in the counties where we ended the growing season. It would not be surprising to see some light frost in some spots of frost in a some locations however.

SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/. Hurricane Teddy will be moving towards Nova Scotia Tuesday while high pressure remain across the Middle Atlantic. A decent pressure gradient will keep some gusty N to NW winds across the region while skies remain mostly clear. After chilly morning temps, readings will climb into the upper 60s and low 70s in most spots. These values will be close to normal for mid/late September. Winds will be from the Northwest at around 10 mph with some gusts closer to 20 mph, especially near the shore.

LONG TERM /TUESDAY NIGHT THROUGH MONDAY/. High pressure establishes itself over the Ohio and Tennessee Valleys Tuesday night. Meanwhile, Hurricane Teddy tracks parallel to, but well east of, the East Coast and moves towards the Canadian Maritimes. High pressure then slides off the Southeast coast through Thursday, and the high gradually slides east through the end of the week.

A weak cold front passes through the region Friday night. Weak low pressure moves into the Southeast this weekend and may track along, but east of, the East Coast. There is some inconsistencies with the models, as high pressure is otherwise in control until a stronger cold front approaches for the start of the new week. Will generally carry slight chance to low chance PoPs, but the best chance for precip will be Sunday night and Monday. Trends over the last few weeks have kept the region dry.

Temperatures warm to near and slightly above normal levels as the week progresses with highs warm into the mid and upper 70s.

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

Tonight . VFR. Mostly SKC except a few high level clouds of around 25,000 feet. Northeast winds around 5 knots or less, becoming light and variable this evening. High confid.

Tuesday . VFR. Mostly SKC. Northwest winds increasing to around 5 to 10 knots after daybreak. Winds will gust 15-20 knots during the afternoon. High confid.

Outlook .

Tuesday night through Saturday . VFR. W-NW winds through Thursday, then S-SW winds.

MARINE. Fair weather will continue tonight and Tuesday. Hurricane Teddy which is well offshore will continue to influence our marine areas with dangerous surf and gusty winds. The SCA flag for the ocean waters will continue tonight and Tuesday with gusts close to 30 knots and seas 7 to 10 ft. The SCA for Delaware Bay has been cancelled as winds are below 25 knots and should remain below 25 knots through the rest of the night. Choppy seas in the bay, especially near the mouth.

Outlook .

SCA conditions on the ocean into Wednesday with the swells and influence from Hurricane Teddy remaining, but diminishing. Conditions will remain sub-SCA after that thru the end of the week. Fair weather much of the week with the next chance of showers expected later next weekend. Rough surf expected Monday night into Tuesday.

Rip currents .

There remains a high risk for the development of dangerous rip currents through Tuesday for all of the Atlantic beaches of New Jersey and Delaware, with a very long-period swell of 5 to 8 feet expected in the surf zone through the period. The high risk will likely continue into Wednesday.Breaking waves are likely to be dangerous, causing localized beach erosion as well. A high surf advisory is in effect through tonight.

TIDES/COASTAL FLOODING. The northeast wind along the coasts of New Jersey and Delaware is forecast to back to the north tonight, then to the northwest on Tuesday. Water should begin to be pushed away from the coast at that time, causing the positive tidal departures to decrease slowly. A west wind is anticipated for Wednesday and that should continue the downward trend for the tide levels. Also, the astronomical tides continue to decrease as we approach Wednesday's first quarter moon.

Some lingering spotty minor flooding remains possible in the coastal counties of New Jersey and Delaware with the afternoon high tides on Tuesday and Wednesday. However, it may not be widespread enough to warrant another advisory. We will continue to monitor the tidal departure trends over the next couple of days.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . High Rip Current Risk through Tuesday evening for NJZ014- 024>026. High Surf Advisory until 6 AM EDT Tuesday for NJZ014-024>026. DE . High Rip Current Risk through Tuesday evening for DEZ004. High Surf Advisory until 6 AM EDT Tuesday for DEZ004. MD . None. MARINE . Small Craft Advisory until 8 PM EDT Wednesday for ANZ450>455.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
