Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay.. A weak cold front will continue moving out to sea tonight and Tuesday, with high pressure building in for midweek. A cold front associated with low pressure moving through the great lakes region will bring a renewed threat of showers and Thunderstorms later Thursday through Friday. High pressure building in from the midwest should then bring increasingly warmer and more humid weather for the end of the week.

Area Forecast Discussion National Weather Service Mount Holly NJ 126 AM EDT Tue Jul 14 2020

SYNOPSIS. High pressure will build into the eastern U.S. through midweek. A backdoor cold front will move south into the area late tonight and Wednesday before lifting northward as a warm front on Thursday and Friday. A weak cold front will approach the East Coast near the end of the week into the weekend, but high pressure in the Southeast will likely aid in its stalling and eventual dissipation.

NEAR TERM /THROUGH TONIGHT/. A potent midlevel trough is moving into New England at this time and will continue its eastward movement today. The trough axis is expected to be offshore by early afternoon, with large- scale descent likely encompassing the region thereafter. Models (convection-allowing and coarser deterministic) are skittish in producing convection near the vorticity maximum in our CWA today, and given the unfavorable position/timing of the trough, I went with a dry forecast today. Having said that, a stray shower/storm is possible, especially near/north of I-80, but chances are simply too low at a given location to justify PoPs at this time.

At the surface, high pressure will move slowly through the Midwest today, with a cold front attendant to the trough slowly migrating farther and farther offshore. In between, weak cold/dry advection should occur, with the result being mostly sunny skies and fairly comfortable humidity levels. Given the degree of insolation and slight downsloping component expected, highs will likely be near to slightly above seasonal averages.

The surface high will progress into the Appalachians by 12z Wednesday, with a quiet night expected in our area as winds decouple and dew points remain seasonably comfortable. Lows are expected to be near or slightly above seasonal averages.

SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/. A mid-level trough and its associated axis will be exiting the coast late Tuesday afternoon and evening, taking any residual precipitation in the northern portion of the CWA with it. Then mid-level and surface ridging will provide benign weather for Tuesday and Wednesday. With an onshore flow and modest dew point temperatures for this time of year, both air temperature and relative humidity should remain fairly comfortable.

LONG TERM /THURSDAY THROUGH MONDAY/. Another frontal boundary associated with a low pressure system moving through the Great Lakes region is expected to bring the chance of showers and thunderstorms to the area late Thursday afternoon through Friday. This front may sag far enough south of the region to provide benign weather during the upcoming weekend, but the combination of a mid-level ridge and southerly flow at the surface will produce increasing warmth and humidity into early next week. An impulse developing along this front may touch off a few showers and thunderstorms, mainly south of the Mason-Dixon line, Sunday night, and scattered showers and thunderstorms are possible again on Monday given an increasingly unstable airmass.

AVIATION /05Z TUESDAY THROUGH SATURDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Rest of tonight . VFR with light northwest winds. High confidence.

Tuesday . VFR with northwest winds around 10 kt. High confidence.

Tuesday night . VFR with light winds. Directions may be predominantly northerly or possibly even northeasterly late, but will likely be rather variable at most terminals. Moderate confidence.

Outlook . Wednesday through Wednesday night . Mainly VFR. E or SE winds 5 to 15 kt. Moderate confidence.

Thursday and Thursday night . Mainly VFR, though chances for showers and storms increase late Thursday afternoon. Brief restrictions possible in their proximity. Southeast winds 5 to 15 kt becoming southerly Thursday night. Moderate confidence.

Friday . Mainly VFR, though chances for showers/storms continue, with brief restrictions possible. South to southwest winds 5 to 15 kt. Low confidence.

Friday Night and Saturday . Mainly VFR. South to southwest winds 5 to 10 kt. Low confidence.

MARINE. Sub-advisory winds/seas are expected through tonight. Winds will likely become southerly for a time today before fairly quickly becoming northwesterly this evening. Thereafter, directions will gradually become north or even northeast by daybreak Wednesday. Speeds will generally be 5 to 15 kt. Seas around 3 feet should be expected.

Outlook . Wednesday through Wednesday night . Sub-advisory winds/seas and fair weather expected.

Thursday through Friday . Sub-advisory winds/seas expected. A chance of showers/storms, with locally higher waves and gusty winds in their proximity.

Friday night and Saturday . Sub-advisory winds/seas expected.

Rip Currents .

Breaking waves are forecast to be 2 feet or less with a medium period southeast swell along the coasts of Delaware and New Jersey on Tuesday. A light and variable wind in the morning is forecast to settle into the south around 5 to 10 MPH in the afternoon. The risk for the development of dangerous rip currents is expected to be low on Tuesday.

The wave and swell conditions are anticipated to remain nearly the same for Wednesday. However, the wind is forecast to become easterly around 10 MPH. The low risk of rip currents is expected to continue.

EQUIPMENT. The NOAA Weather Radio All Hazards broadcast from Hibernia Park, PA (WNG704) remains off the air until further notice due to damage to the antenna during the June 3 derecho.

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.

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