High pressure looks to return to end the weekend and start the new week.

Area Forecast Discussion National Weather Service Mount Holly NJ 126 AM EDT Tue Apr 23 2024

SYNOPSIS
High pressure extending eastward from the Midwest to the Mid- Atlantic will continue to build eastward toward the East Coast today. A cold front will swing through our region on Wednesday, followed by another area of high pressure pushing southeastward from the Great Lakes Thursday and Friday. An approaching warm front will bring a chance for some rain showers over the weekend.

NEAR TERM /THROUGH TONIGHT/
Latest analysis depicts an elongated ridge of surface high pressure extneding from the Southeast northeastward into Atlantic Canada. Dry air, mostly clear skies and light winds have promoted strong radiational cooling and we should have fairly widespread frost early this morning, with frost and freeze headlines remaining in effect until 9 AM. Otherwise, the day should dawn sunny and calm.

Incoming system still over the central Plains and upper Midwest will begin to spread some high clouds overhead today, but otherwise, should be fairly sunny. With warm advection developing ahead of the system on strengthening southerly flow, expect highs to rise 5-10 degrees above yesterday's readings, which will feel quite nice after the chilly morning. Winds will be a little gusty, perhaps up to 20 mph, but not much different from yesterday.

The approaching system will further increase clouds with a steady southerl flow tonight. This will help keep temps much milder, with lows likely 10-15 degrees higher than this morning, mostly 40s and low 50s. As the system gets closer late at night, a few shower may move into the region, but overall not expecting much, so kept overnight POPs in the slight chance to low-end chance range.

SHORT TERM /WEDNESDAY THROUGH THURSDAY/
Clouds will return Wednesday as low pressure tracking across Quebec and northern New England swings a cold front toward our region. Model guidance has continued to advertise an earlier initial frontal passage pushing offshore Wednesday morning.
Following an initial frontal passage early in the day, a secondary front looks to approach by late day. Models are indicating conditionally unstable conditions Wednesday afternoon with this, and with the mid-level trough also approaching, there may still be some pop up showers with even some rumbles of thunder in the afternoon, especially northwest of the Fall Line. And given fairly steep lapse rates in the low and mid levels, some of these showers/storms could even contain some hail and gusty winds. This system continues to look quite moisture starved as well, without a tap to moisture from the Gulf of Mexico. Rainfall amounts should be less than a quarter- inch, and perhaps less than a tenth of an inch, for most locations through Wednesday. Expect warm temperatures for the most part on Wednesday, at least southeast of the Appalachians, but accompanied by brisk northwest winds in the afternoon and evening. Skies will clear as high pressure quickly builds southeastward from the Great Lakes Wednesday night, across the Northeast and Mid-Atlantic Thursday morning. If the atmosphere can decouple and winds calm, that could set the stage for another frosty morning in spots, especially the more favorable locations like interior NJ and eastern PA north and west of the Fall Line.

Thursday is shaping up to be mainly sunny and cooler under the influence of high pressure with highs in the 50s to around 60.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
Expect dry weather and mostly clear skies through Friday as strong high pressure remains in control along the Mid-Atlantic coast.
Friday morning may see yet another frosty morning inland and outside perhaps the most urban areas. Afternoon highs should then be in the 50s to low 60s. Models continue to struggle with the forecast specifics regarding any rain over the weekend, but the general synoptic set-up looks to be low pressure lifting across the upper Great Lakes, with a warm front trying to cross the Appalachians.
That may bring some showers in, particularly across eastern PA at some point over the weekend, but at this point am not expecting a washout by any means. Sunday may finally see some high temperatures rising above seasonal averages, possibly into the 70s. This looks to continue into Monday with increasing shower/storm chances by late day as a cold front starts to approach.

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

Through today...VFR. Light and variable winds early become southerly 5-10 kts after daybreak. Gusts of 15-20 kts possible later in the morning into the afternoon. High confidence.

Tonight...VFR. A few showers are possible late, but no reductions in cigs or vsby expected before dawn Wednesday. Winds southerly 5-10 kts. High confidence.

Outlook...

Tuesday Night - Wednesday...Potential for MVFR conditions at times, as a cold front brings showers and a wind shift from southerly to W/NW.

Thursday - Friday...VFR.

Saturday...Potential for stratus deck with MVFR cigs.

MARINE
Today, winds start below advisory levels, but will increase through the day and likely reach Small Craft Advisory levels on the northern half of the New Jersey coastal waters, as well as Delaware Bay. Therefore we have issued a Small Craft Advisory for these areas. Tonight, the gusts on the bay diminish, but on the oceans they should increase, so SCA's expand to all ocean zones after midnight. Seas will also build, reaching low-end criteria by early Wednesday morning.

Outlook...

Wednesday... Small Craft Advisory conditions expected, at least due to seas. SW winds around 15 kt gusting 20 to 25 kt, shifting to the W/NW later in the day as a cold front swings through. Seas 5 to 6 ft.

Thursday...SCA possible early in the morning due to lingering elevated seas. Diminishing NE to E winds. Seas 3 to 5 ft.

Friday...Easterly winds 10-15 kt. Seas 2 to 3 ft.

Saturday...Southeast winds 10 t0 15 knots. Seas 3 to 4 feet.

FIRE WEATHER
Though there will be some moisture advection with an approaching system, the region will remain fairly dry today. Min RH values across the region will be in the 25-35% range, with southerly wind gusts in 15-25 mph range. As was done for Monday, a Special Weather Statement for increased fire danger has been issued for today.

TIDES/COASTAL FLOODING
A prolonged period of southerly flow will develop during the middle of the week ahead of a cold front that will push offshore on Thursday. This is forecast to result in surge values rising to around 1-2 feet above normal along Delaware Bay, the tidal Delaware River, and Chesapeake Bay. With the full moon occurring on Tuesday, astronomical tides will be maximized around this time as well. This should result in some areas of minor coastal flooding with the Wednesday night high tide, although the extent and exact areas that may experience the most impact remains unclear at this time.

Coastal flooding is not currently anticipated along the Atlantic coast, except for potentially Barnegat Bay.
