Area Forecast Discussion National Weather Service Mount Holly NJ 103 AM EDT Wed Apr 23 2025
SYNOPSIS
High pressure builds down out of Canada and into the Mid-Atlantic region through Wednesday. The high then shifts offshore Wednesday night into Thursday, with a warm front lifting northward across the area Friday night. A cold front will follow for Friday night into Saturday as low pressure lifts to the northeast out of the Ohio Valley Friday and into New England through Saturday. High pressure returns for Sunday into Monday.
NEAR TERM /THROUGH TODAY/
No real changes to the grids. Nudged temperatures up a few degrees, but lows should still end up near the original forecast. Otherwise, we are on track. Quiet night ongoing with some showers skirting by south of Delaware.
Otherwise, high pressure from the Great Lakes builds in tonight and keeps fair weather across our area. The new airmass is several degrees cooler that the previous one so low temperatures tonight are forecast to drop into the 40s to low/mid 50s across the region.
Wednesday, a mostly sunny sky is forecast. High temperatures will range from the upper 60s for the Poconos to the mid 70s for metro Philadelphia and southern NJ. A north to northeast wind is expected and a sea breeze should organize and move inland some toward late morning and in the afternoon. This should turn the winds to more east to southerly especially east of the sea breeze front. The wind speeds are expected to be much lighter Wednesday however compared to today. Highs will be noticeably cooler (50s/60s) along the coastal areas with an onshore flow developing/strengthening by afternoon.
SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/
High pressure will build offshore beginning Wednesday night and remain near the are through Thursday night. This will keep fair weather in the forecast through Thursday night, with temperatures above normal.
LONG TERM /FRIDAY THROUGH TUESDAY/
The high will begin to move out to sea through the day Friday, before a warm front lifts across the area later Friday into Friday night. A couple of short wave/vorticity impulses may move across the area during the day, which could lead to a few shower during the afternoon north of the warm front. By Friday night into, a cold front will approach and move across the area as an area of low pressure moves out of the Ohio Valley Friday night and into New England through Saturday. Shower chances will increase Friday night into Saturday, and with some weak instability, there is an isolated chance of a few thunderstorms.
As PWs increase to over 1.5 inches in some areas, some period of moderate to heavy rain will be possible. Above normal temperatures will remain for Friday into Saturday.
The cold front pushes offshore Saturday night, before high pressure builds into the Mid Atlantic region Sunday into Monday, before shifting offshore Monday night and out to sea Tuesday.
Dry weather will return for Saturday night through Tuesday, and after a brief period of near normal temperatures Saturday night int Sunday, above normal temperatures return for Sunday night through Tuesday.
AVIATION /05Z WEDNESDAY THROUGH SUNDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Tonight...VFR with high clouds. West to northwest winds 5-10 knots, becoming light and variable at may sites. The winds then become north to north-northeast near 5 knots toward daybreak. Moderate confidence.
Wednesday...VFR. North to northeast winds 5-10 knots, becoming southwest or south. A sea/bay breeze develops and should shift the winds to east and southeast at KACY, KILG and possibly MIV.
Low confidence on wind direction details/timing.
Wednesday Night...VFR. Winds light and variable, potentially favoring a southerly direction if anything, 5 kt or less. High confidence.
Outlook...
Thursday-Thursday night...VFR.
Friday-Saturday...Sub VFR conditions, especially Friday night into early Saturday as shower chances increase.
Saturday night-Sunday...VFR.
MARINE
Tranquil conditions continue tonight and Wednesday with high pressure across the area. The conditions are expected to remain below Small Craft Advisory criteria. A sea and bay breeze developing during Wednesday should result in an increase in the winds some especially nearshore.
Outlook...
Wednesday night-Friday...Conditions expected to remain below advisory levels.
Friday night-Sunday...Winds remain below advisory levels, however seas may approach and linger near 5 feet through the weekend.
FIRE WEATHER
The relative humidity will continue to rebound tonight as temperatures cool and the winds diminish due to lowering mixing heights.
The relative humidity values are a touch lower for much of the area Wednesday and Thursday, but winds will be lighter. Sea/bay breezes Wednesday should result in a recovery of the relative humidity to its east. Relative humidity recovers more this weekend. Given lighter winds, there are no fire weather concerns expected regarding rapid fire spread.
