Area Forecast Discussion National Weather Service Mount Holly NJ 325 PM EDT Sat Apr 4 2020

SYNOPSIS. A weak ridge of high pressure will build over the area tonight and remain into Sunday. A weak cold front will cross the area Sunday afternoon and evening. More high pressure returns for Monday. A disturbance will bring unsettled conditions for the middle the upcoming week. Another low and its fronts will arrive for Friday and remain nearby into next weekend.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. The large ocean storm that has been affecting our weather continues to sit and spin well out at sea as it slowly moves away. However as it does so, it has spun back one last band of cloud cover that continues to persist across most of the area at this hour. However some drier air with developing partial sunshine has begun to work into parts of northern NJ.

As we go through the rest of this afternoon into early this evening, the trend will continue to be for drier air to work in from the north as weak surface ridging takes hold. This will result in increasing sunny breaks developing from NE to SW through the remainder of the daylight hours. Any left over spotty drizzle should also come to an end.

Heading through the later evening into the overnight, the area will be situated in a weak flow regime between systems as the ocean storm continues to move away while a weak frontal system drops into the lower Great Lakes. The approach of this next system will help keep skies mostly cloudy overnight. There could also be a few light showers or sprinkles overnight over NE PA into NW NJ as a weak shortwave moves over the top of the fairly flat upper level ridge that will be over the region. POPs are capped though at the slight chance range and anything that falls won't amount to much. Overnight lows will be mainly in the low to mid 40s.

SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/. Overall, another fairly quiet day on tap weatherwise. A weak cold front will continue to slowly approach from the north but ahead of it the W/SW flow will result in milder temperatures. There will also continue to be a fair amount of cloud cover but there should be at least a little more sunshine compared to today. Generally expect highs in the mid 60s except upper 50s to low 50s over NE PA into NW NJ. Most of the day should be dry but by late day there could be some isolated showers moving into eastern PA ahead of the aformentioned front.

LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/. Sunday night thru Monday night . A mostly dry period, especially Monday which looks like a nice day with high pressure building overhead. Isolated showers may arrive Monday night as a warm front begins to push towards the area from the Ohio valley. I put just a slight chc for a shower at this point. The milder temperatures that arrive for late this weekend will continue into next week with readings 5 to 10 degrees above normal.

Tue thru Wed . A deepening upper trough across the northern Rockies and Plains states will stir up a sfc cyclone across the Great Lakes region Tue which will head east across New England into Wed. This will bring scattered to occasional showers to the area Tue thru Wed, with the cold front expected to cross the area Wed afternoon, a few tstms are also possible since a mild and humid airmass will be in place. Highs and lows will remain generally 5 to 10 degrees above normal. Highs will be in the upper 60s to low 70s for Delmarva and low to mid 60s

Wed night and beyond . Mostly unsettled with the upper trough deepening across the Great Lakes and then swinging across the Northeast late week. Another low pressure system will spin up across Canada Thu and send a stronger cold front across the Middle Atlantic towards the end of the week. There will be some chc for showers Thu thru Sat with the greatest chc for Thu. Uncertainty builds during the end of the week with some of the models slower with the system. Temperatures will drop back to normal Fri and then remain either normal or below into next weekend. Some higher elevation snow showers are possible next weekend.

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

Tonight . Mainly VFR conditions expected. A few ceilings around 2500- 3000 ft may continue to move through the region but skies are expected largely clear out by 23-00Z. Some model guidance is suggesting a period of MVFR ceilings late tonight. Confidence was too low to include at this time. Winds will become light and variable this evening and remain down through much of the night. Where winds do pick up (generally 5 knots or less), the direction will become more southwesterly overnight. Moderate confidence.

Sunday . Mainly VFR conditions expected. Light winds early will become southwest to west around 10 knots. High confidence.

Outlook .

Sunday night . Mainly VFR conditions. Light southwest to west winds, becoming northwest overnight. MVFR conditions possible as scattered showers move through during the night. Moderate confidence with low confidence on MVFR conditions.

Monday . VFR conditions expected. Northwest to west around 5 to 10 knots. Moderate confidence.

Tuesday . Mainly VFR conditions expected. Light southwest winds less than 10 knots. MVFR or lower conditions possible in rain showers. Moderate confidence.

Wednesday . MVFR or lower conditions possible in showers with isolated thunderstorms. Westerly winds 10 knots or less. Moderate confidence with low confidence on thunderstorms.

Thursday . MVFR or lower conditions possible in showers. Southerly winds around 5 to 10 knots. Low confidence.

MARINE.

The SCA remains in effect for all of our ocean zones through the day Sunday. This is mainly for seas as the general trend has been for winds to diminish. Seas should generally be in the 5 to 8 foot range through tonight and in the 4 to 6 foot range for Sunday.

Outlook .

Sunday night . SCA conditions into the evening and early overnight before diminishing. Scattered showers early.

Monday thru Wednesday . Generally sub-SCA. Sct showers Tue night and Wed otherwise, Fair.

TIDES/COASTAL FLOODING. Low pressure centered well off the Middle Atlantic coast this afternoon will continue to move farther out to sea. The onshore wind flow along the coasts of Delaware and New Jersey will cease this evening.

We expect tidal departures to decrease gradually overnight and on Sunday along the oceanfront. However, spotty minor flooding is anticipated around the times of the next two high tide cycles, the one this evening and the one on Sunday morning. The flooding is not expected to be widespread enough to warrant an advisory.

A minor surge was working its way up Chesapeake Bay this afternoon. Water levels along the upper eastern shore of the bay will be on the increase overnight into Sunday. As a result, spotty minor flooding is also possible there around the times of high tide overnight and on Sunday.

No additional minor flooding is expected during the early part of the new week.

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.
