Area Forecast Discussion National Weather Service Mount Holly NJ 332 AM EDT Fri Aug 14 2020

SYNOPSIS. A frontal boundary will slowly sag southward through Saturday, before stalling to our south Sunday as high pressure builds across eastern Canada. Several waves of low pressure will move along this boundary, keeping unsettled weather across the area. The low pressure system that moves across the area late Sunday into Monday will push the frontal boundary offshore. This will allow another cold front to move across the area late Monday into Tuesday, which may stall to our south and offshore next week.

NEAR TERM /UNTIL 6 AM THIS MORNING/. Dew point temperatures were in the lower and middle 60s in the Pocono Region and far northern New Jersey early this morning. However, abundant low level moisture was lingering in southeastern Pennsylvania, central and southern New Jersey, Delaware and northeastern Maryland. Those areas will continue to see some low clouds and patchy fog early this morning.

Low pressure was located off Cape Hatteras during the predawn hours, and it will move slowly to the northeast today. The circulation around the low is expected to continue drawing showers off the ocean and into eastern Maryland, Delaware and southern New Jersey. The showers are forecast to reach the Interstate 95 Corridor in our region this morning.

A strengthening northeast flow is anticipated to bring increasingly stable air into our region from the northeast during the course of the day. As a result, the chance of showers is forecast to begin decreasing in eastern Pennsylvania and New Jersey this afternoon. The higher chances for showers and scattered thunderstorms will be in Delaware and northeastern Maryland where marginal instability is forecast to pool during the afternoon hours.

High temperatures are expected range from the upper 70s to the middle 80s in our region.

SHORT TERM /6 AM THIS MORNING THROUGH 6 AM SATURDAY/. The surface low is expected to continue drifting northeastward tonight, to a point about 300 miles off the Delaware coast around daybreak on Saturday. The resulting northeast flow will draw stable and relatively dry air into our region overnight. While there is a lingering chance of showers in northeastern Maryland and Delaware, no precipitation is expected in eastern Pennsylvania or New Jersey.

A partly cloudy sky is anticipated for tonight with a northeast wind around 5 to 10 MPH. Low temperatures should be mostly in the 65 to 70 degree range.

LONG TERM /SATURDAY THROUGH THURSDAY/. Periods of unsettled weather are expected to affect portions of the area for much of the long term period with several waves of low pressure moving along frontal boundaries near the area.

For Saturday, the frontal boundary will continue to sag southward and we will be in between two surface low pressure systems that will move along the frontal boundary. Although we will be in between the two surface lows, southwest flow aloft will remain across the Mid- Atlantic region. Multiple short waves/vorticity impulses will move across the area within the southwest flow aloft, and with plenty of moisture across the area as evident of PW values of 1.5-2.0+ inches, there will remain chances of showers and thunderstorms. The rain chances are fairly small however, so Saturday may end up being a fairly dry day for many areas.

By Saturday night into Sunday, a stronger wave of low pressure is forecast to move along the stalled front, and pass near the area. The guidance still varies in respect to their placement of the actual low and the placement of the precipitation. There will be a chance of showers and thunderstorms for all areas, although southern portions of the area will be favored for heavier precipitation potential since they will be closer to the track of the low and have the higher PW values of over 2 inches.

Behind the low Sunday night, moisture will likely remain across the area, and patchy fog and drizzle may develop across portions of the area.

The low will track to the northeast and across New England Monday into Monday night, while a cold front approaches the area from the west. Rain chances lower some Monday into Monday night, although they will not disappear completely.

For Tuesday through Thursday, the front may stall to our south. Tuesday may be a mostly dry period as we will be lacking moisture and any short waves/vorticity impulses. This may change as we move into Wednesday and Thursday as several short waves/vorticity impulses will likely move across the area within the southwest flow aloft and combine with some enhanced moisture, leading to a chance of showers and thunderstorms for portions of the area.

AVIATION /07Z FRIDAY THROUGH TUESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today . Widespread MVFR/IFR conditions early this morning due to low clouds and fog. Conditions improving to VFR for this afternoon. Scattered showers with isolated thunder. Northeast wind 5 to 10 knots. Medium confidence.

Tonight . Mainly VFR. Northeast wind 5 to 10 knots. Medium to high confidence.

Outlook .

Saturday . Generally VFR conditions. Showers and thunderstorms possible in the afternoon may temporarily lower conditions. East winds 5-10 knots, with gusts 15-20 knots.

Saturday night-Sunday . An extended period of MVFR or IFR conditions possible. A chance of showers and thunderstorms, especially Saturday night into Sunday. East-northeast winds 5-10 knots, with gusts 15-20 knots.

Sunday night . MVFR or IFR conditions likely continue with fog and drizzle possible. East-northeast winds 5-10 knots, becoming light overnight.

Monday . MVFR conditions likely early, with possible improvement during the day. Chance of showers and thunderstorms. North winds early, become west-northwest during the day 5-10 knots.

Monday night . Generally VFR conditions. Winds become light and variable overnight.

Tuesday . VFR conditions expected. Northwest winds 5-10 knots.

MARINE. As low pressure drifts slowly northeastward off the Middle Atlantic coast today and tonight, a northeast wind is forecast to continue along the coasts of Delaware and New Jersey. Wind speeds are expected to increase to 15 to 20 knots, with some gusts to 25 knots on the coastal waters of New Jersey tonight. Wave heights on our ocean waters are anticipated to build to 4 to 5 feet for tonight. We will begin a Small Craft Advisory for the water off New Jersey at 10:00 PM this evening. Small Craft Advisory conditions are not expected on the waters off Delaware or on the waters of Delaware Bay until around daybreak on Saturday.

Outlook . Saturday-Saturday night . Small Craft Advisory in effect as seas are expected to build to at least 5-6 feet due to increasing easterly flow. Winds could gust 25-30 knots Saturday into Saturday night.

Sunday-Sunday night . Small Craft Advisory conditions likely continue as winds and waves remain elevated.

Monday-Tuesday . Conditions likely lower below advisory levels through the day Monday and remain below advisory conditions through Tuesday.

Rip currents .

There is a low risk for the development of dangerous rip currents today. However, the risk could become locally moderate as a northeast wind around 15 MPH develops. Breaking waves should be 2 to 3 feet with a medium period swell from the southeast.

A moderate risk is anticipated for Saturday. The northeast wind is forecast to increase to 15 to 20 MPH with gusts of 25 MPH. Breaking waves of 3 to 4 feet are expected with a short to medium period wind wave from the northeast.

TIDES/COASTAL FLOODING. Onshore flow will increase some Friday and especially Saturday and persist through Sunday. Astronomical tides will be increasing into the weekend as well as the new moon occurring early next week. These factors will combine to increase the chance for minor coastal flooding with the Saturday and Sunday afternoon/evening high tides. Spotty minor coastal flooding is possible with the afternoon and evening high tide on Saturday. Minor coastal flooding to advisory levels is then more likely with the Sunday afternoon and evening high tide, especially from Atlantic City southward including the Delaware Atlantic coast and up Delaware Bay.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory from 10 PM this evening to 6 AM EDT Sunday for ANZ450>453. Small Craft Advisory from 10 AM Saturday to 6 AM EDT Sunday for ANZ454-455.
