Area Forecast Discussion National Weather Service Mount Holly NJ 338 PM EDT Fri Sep 18 2020

SYNOPSIS. High pressure centered in the western Great Lakes this afternoon will build slowly to the east. The air mass is forecast to settle along the Appalachians early in the new week. The high should continue to influence our weather into Thursday. A weak cold front approaching from the northwest is expected to arrive early on Friday.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. High pressure will continue to affect our weather tonight with dry and cool air advecting across the region. A gusty N to NE wind will continue into the early evening with speeds mostly 10 to 15 mph and some gusts closer to 20 mph through about 800 PM. It will be rather chilly tonight with lows dropping into the mid/upper 40s in most spots and some low 40s or perhaps even some upper 30s far N/W. A bit of patchy frost in the more sheltered valleys is also possible, but any widespread frost is not expected.

SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/. High pressure over the Great Lakes will continue to build across the MIddle Atlantic. Fair weather with cool dry air will remain in place. Mostly sunny skies are expected with temperatures topping out mostly in the 60s across the area. These highs will be roughly 10 degree below normal for mid- September. Winds will be mostly N to NE at 5 to 10 mph.

LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/. The weather over the western North Atlantic will remain rather active from Sunday into the early part of the new week. Meanwhile, conditions will be tranquil in our area.

High pressure is forecast to be centered in the Saint Lawrence River Valley and vicinity on Saturday night and Sunday. The air mass is expected to build southward along the Appalachians on Monday and Tuesday, before drifting eastward across the Carolinas and off the coast on Wednesday and Thursday. The high should bring dry weather to our region during the period.

Below normal temperatures are anticipated for Sunday, Monday and Tuesday, as we welcome autumn. Patchy frost is possible up north early on Sunday morning and again early on Monday morning. The air mass will modify and temperatures will likely rise above normal for Wednesday and Thursday.

A weak cold front is forecast to approach from the northwest on Thursday night and it should pass through our region early on Friday. The feature is expected to have only limited moisture associated with it. Temperatures on Friday should return near normal.

AVIATION /20Z FRIDAY THROUGH WEDNESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Rest of the evening . VFR. Decreasing clouds with some 035-040 CIGS SE. Gusty N to NE winds 10 to 20 knots. High confid.

Tonight . VFR. Skies becoming SKC after sunset. Northeast winds 10 to 15 knots decreasing slowly. High confid.

Saturday . VFR expected with clear skies much of the day. North to northeast winds 5 to 10 knots. High Confid.

Outlook .

Sunday . VFR. Northeast wind 10 to 15 knots with gusts around 20 knots. High confidence.

Monday . VFR. Northeast wind around 10 knots. High confidence.

Tuesday . VFR. Northwest wind around 10 knots. High confidence.

Wednesday . VFR. West wind 5 to 10 knots. High confidence.

MARINE. Fair weather tonight and Saturday. SCA flags will continue with gusts around 25 knots and enhanced seas on the ocean. It's possible that the SCA flag for the northern Del Bay could be taken down this evening if wind gusts decrease later on.

Outlook .

Saturday night and Sunday . A Small Craft Advisory is in effect for our ocean waters and for Delaware Bay. A northeast wind is forecast to be 15 to 25 knots will gusts around 30 knots. Waves on our ocean waters will likely build to 6 to 10 feet.

Sunday night and Monday . The Small Craft Advisory will likely need to be extended to cover this period as the gusty northeast wind and rough seas continue.

Monday night through Wednesday . While wind speeds are expected to fall below 25 knots, wave heights on our ocean waters should be slow to drop below 5 feet. As a result, a Small Craft Advisory may be needed for our ocean waters for most of this period, as well.

Rip currents .

There is a high risk for the development of dangerous rip currents into tonight at the Delaware Beaches. There is a moderate risk at the New Jersey Shore. A high risk is expected for both Delaware and New Jersey on Saturday due to the rough surf and strong northeast wind.

Rough surf will continue along the coasts of Delaware and New Jersey from Saturday night into Tuesday as the weather pattern over the western North Atlantic remains active. As a result, there will be an enhanced risk for the development of dangerous rip currents through the period.

TIDES/COASTAL FLOODING. The new moon occurred on Thursday and higher than normal astronomical tides will continue for the next couple of days.

For the Atlantic coast: A continued north to northeast flow will increase the surge along the Atlantic coast. With astronomical tides running higher than normal due to the recent new moon, we are expecting minor flooding to occur with tonight's and especially Saturday mornings high tides. Can't rule out a few spots mainly south of Barnegat Bay getting close to or just touching Moderate flooding levels with the Saturday morning high tide but confidence remains too low to issue any Coastal Flood Watch or Warning products at this time.

For the Delaware Bay and tidal Delaware River: A north to northeast wind is not likely to increase the potential for tidal flooding along the Delaware River. However, the winds will be blowing across the Delaware Bay and this will increase the risk along the southern bay shores of Delaware, where we expect minor tidal flooding to occur with tonight's and Saturday morning's high tides.

For the Northeast Chesapeake Bay: We do no expect any coastal flooding to occur along the Chesapeake Bay as the north to northeast wind direction is not ideal for tidal flooding.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . Coastal Flood Advisory from 8 PM this evening to 2 PM EDT Saturday for NJZ013-014-020-022>027. Coastal Flood Advisory from 8 AM to 2 PM EDT Saturday for NJZ012. DE . Coastal Flood Advisory from 8 PM this evening to 2 PM EDT Saturday for DEZ002>004. High Rip Current Risk until midnight EDT tonight for DEZ004. MD . None. MARINE . Small Craft Advisory until 6 PM EDT Sunday for ANZ430-431- 450>455.

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