Area Forecast Discussion National Weather Service Mount Holly NJ 343 PM EDT Sun Apr 5 2020

SYNOPSIS. A weak cold front will cross the area this evening. High pressure will begin to build in later tonight and remain into Monday. A warm front will approach the area Tuesday as low pressure develops over the Great Lakes. This low will move north of the area during the midweek period. Another stronger low will cross New England during Thursday and Friday. Much colder air will move in for the late week and remain through next weekend.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. A few light sprinkles or showers may move through portions of the area this afternoon into early evening in advance of an approaching cold front. A low pressure system located well north of our region in eastern Canada, will drag a weak cold front across our area tonight accompanied by some rain showers, mainly occurring overnight. Rainfall amounts look to be fairly light, with some areas maybe seeing up around a tenth of an inch. Precipitation will end from west to east, and should clear the coast by early Monday morning.

Increasing cloudiness will occur through this evening. With the rain moving through and cloudy skies, do not anticipate that temperatures will really drop off all that much and think it will remain relatively mild overnight. Only hitch in that thinking is how fast the dry air arrives behind the front, mainly across our northern and western most areas. Should the the dry air arrive sooner in those area, the skies will clear out pretty quickly and we could see a quick drop in temperatures right around daybreak. Temperatures overnight will generally range from the upper 30s across the north to the mid to upper 40s elsewhere.

SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/. Any linger showers, mainly towards the coastal areas, should end fairly quickly Monday Morning. Skies will clear as high pressure builds across the region and dry air starts to overspread the forecast area in the northwest flow. With little cloud cover and plenty of sunshine, we should see temperatures rise into the 60s across the area with some 50s remaining across the higher elevations of the southern Poconos and portions of northwest New Jersey. With lighter winds through the day, a sea breeze may develop along the coast during the afternoon.

LONG TERM /MONDAY NIGHT THROUGH SUNDAY/. Monday night . The high pressure will be weakening across the area early, then a warm front will start to push its way into the region with low pressure well to the NW. Increasing clouds along with a slight chc for a shower expected Monday night. Overall, most areas will be dry. Lows will be seasonable with upper 30s/low 40s N/W and low/mid 40s elsewhere.

Tue/Wed . Low pressure will deepen and move north of the area. Increasing pops with a chance for tstms Wed afternoon. Much milder air arrives with the system with highs Tue in the 60s for most areas and 70s in many areas Wed. More humid air will overspread the region too. Mostly chc pops are in the grids for Tue and then some high chc/low likely pops for Tue night and into Wed.

The late week period will feature a sharp change in temperatures and unsettled conditions as low pressure deepens across New England and then passes into the North Atlantic. Although the models are offering some variety with regards to solutions, there is enough similarity to call for increased pops (Thu.), increasing winds and sharply colder air for Thu/Fri. Highs on Fri will be some 20 degrees colder than Wed's temps across the Middle Atlantic. The cool temps will likely persist into the weekend. Overnight lows may be cold enough for some frost/freeze concerns especially across the N/W areas.

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

Tonight . Generally VFR ceilings. Scattered rain showers between about 03Z and 09Z may lower conditions to MVFR for a short time. Southwest to west wind 8 knots or less, becoming north 5 to 10 knots after 06Z. High confidence.

Monday . VFR with scattered clouds. North to northwest wind 5 to 10 knots. The sea breeze front may reach KACY in the afternoon resulting in a wind shift to the southeast and south. High confidence.

Outlook .

Monday night . Mainly VFR. Variable wind 6 knots or less. High confidence.

Tuesday . Mainly VFR with a chance of showers. Southwest wind 5 to 10 knots. Medium confidence.

Tuesday night . Conditions lowering to MVFR with showers becoming likely. Variable wind 6 knots or less. Medium confidence.

Wednesday . MVFR/VFR conditions. A chance of showers and afternoon thunderstorms. Southwest wind around 10 knots, becoming northwest. Medium confidence.

Wednesday night . Generally MVFR conditions. Variable wind 6 knots or less. Medium confidence.

Thursday . Generally MVFR conditions with showers likely. Southwest wind 5 to 10 knots, becoming northwest 10 to 15 knots. Medium confidence.

Thursday night . Mainly VFR. Northwest wind 10 to 15 knots. Medium confidence.

Friday . Mainly VFR. Northwest wind 15 to 20 knots and gusty. Medium confidence.

MARINE. Small Craft Advisory conditions continue on the area waters with seas in the 5 to 6 foot range. Seas will remain elevated through tonight, subsiding into Monday morning. The guidance has been too progressive of late with subsiding seas so we have decided to extend the Small Craft Advisory out on the ocean waters through 6AM. Seas look to subside from north to south and our coastal Delaware waters may linger a bit longer around 5 feet into Monday morning.

Winds are generally out of a southerly direction, favoring south to southwest around 10 to 15 knots. Winds will turn to the west and then northwest as a cold front cross the area waters tonight. Winds will remain around 10 to 15 knots on Monday and become northerly and then more easterly through the day.

Outlook . Generally sub-SCA conditions thru the period. Showery conditions Tue/Tue night and again Thu. A chance for tstms Wed afternoon. Winds and seas build later Thu/Thu night.

TIDES/COASTAL FLOODING. There was another round of localized minor tidal flooding today in New Jersey and Delaware, and up into the tidal Delaware River. Tidal departures are forecast to continue decreasing, so no additional issues are anticipated into the early part of the new week.

Water remains trapped in Chesapeake Bay. It is forecast to result in some minor flooding with the high tide into this evening along the upper eastern shore. A Coastal Flood Advisory is in effect there.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . Coastal Flood Advisory until 10 PM EDT this evening for MDZ008- 012. Coastal Flood Advisory until 7 PM EDT this evening for MDZ015- 019-020. MARINE . Small Craft Advisory until 6 AM EDT Monday 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.
