Area Forecast Discussion National Weather Service Mount Holly NJ 624 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 TONIGHT/
High pressure will settle over the area today and into tonight resulting in a very nice day. Skies will be mostly sunny to partly cloudy with highs in the mid to upper 70s. With weak flow due to the high in place, conditions are ripe for the development of a sea- breeze and bay breeze. This could result in highs near the coast being a few degrees cooler in the 60s and low 70s.
For tonight, skies will be mostly clear with calm winds. This will result in temperatures dropping a good 25-30 degrees with favorable radiational cooling conditions. Lows will be in the upper 40s to low 50s.
SHORT TERM /THURSDAY THROUGH FRIDAY/
No real changes to the forecast through the rest of the week as high pressure will keep the area under dry conditions with temps running a few degrees above normal. Ensemble means and ensemble cluster analysis show no appreciable differences through Friday.
Max temps will warm into the upper 70s with lows Thursday in the upper 40s to low 50s.
LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/
High pressure starts moving offshore Friday night as highs start falling aloft and a warm front moves through at the surface. The warm front will lead to temps staying in the 60s overnight Friday night and will lead to an increase in low level moisture with PWATs approaching 1.5 inches. Mid level PVA will track the region as consensus guidance brings a positively tilted trough with several impulses. At the surface this will feature a cold front that will be the surface trigger for showers with some isolated thunderstorms.
The primary impact over the weekend will be rounds of moderate to heavy rainfall on Saturday. Tall skinny CAPE profiles with warm cloud depths approaching 10,000ft suggest fairly efficient rainfall. NBM probs suggest generally a 20% chance of greater than 1" for most of the forecast area.
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 /12Z WEDNESDAY THROUGH SUNDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Today...Primarily VFR. The exception being KACY, where smoke from the wildfire to the north is moving over the terminal.
Added a TEMPO group that could result in MVFR conditions.
Cannot rule out brief periods of reduced visibility either with smoke. Smoke could linger over the terminal until the sea- breeze develops and moves through, but only kept a TEMPO group through 14z for now. 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.
Tonight...VFR. Winds light and variable, potentially favoring a southerly direction if anything, 5 kt or less. High confidence.
Thursday...VFR. Southerly winds around 5-8 kt. High confidence.
Outlook...
Thursday night...VFR.
Friday...VFR with increasing cloud cover.
Friday Night-Saturday night...Sub VFR conditions as showers impact the region with a small chance (10%-15%) of thunderstorms during the day Saturday.
Saturday night-Sunday...VFR.
MARINE
Sub-SCA conditions expected through tonight. Winds less than 10 kt.
Seas 2 to 3 feet.
Outlook...
Thursday-Friday...Sub SCA with seas 2-3 feet and winds less than 20kts.
Friday night-Sunday...Sub-SCA winds but seas will build to 4-5 feet with SCA anticipated on Saturday. Showers expected on Saturday.
FIRE WEATHER
Relative humidity values will be lower than yesterday, around 20- 25%, but winds will be light and under 10 MPH. Sea/bay breezes today should result in a recovery of the relative humidity near the coast and also bring a switch in wind direction to the south/southeast.
Similar conditions expected on Thursday, with RHs near 25-35% and light winds.
Relative humidity recovers more this weekend. Given lighter winds, there are no fire weather concerns expected regarding rapid fire spread.
PHI WATCHES/WARNINGS/ADVISORIES
PA...None.
NJ...None.
DE...None.
MD...None.
MARINE...None.
