Area Forecast Discussion National Weather Service Mount Holly NJ Issued by National Weather Service Baltimore MD/Washington DC 350 PM EDT Wed May 1 2024
SYNOPSIS
A warm front lifts through tonight. A cold front looks to cross through Thursday before more weak surface high pressure builds in. Cold front well to our west approaches slowly for Friday and the weekend while decaying, keeping things unsettled this weekend and even into Monday. Yet another cold front may come through around the time frame of Monday/Tuesday.
NEAR TERM /UNTIL 6 AM THURSDAY MORNING/
Ample fair weather cumulus persists across the region this afternoon, with high temperatures on track to reach the upper 70s to low 80s. Winds remain light and northwest for most of the area, but a seabreeze slowly advancing inland is beginning to turn winds out of the S/SE for areas along the coastal plain.
High pressure off to the east will result in widespread onshore flow overnight. The previous cold front returns northward as a warm front by Thursday morning, winds shifting S/SW. With the onshore flow, low cigs/fog likely develops late tonight.
Guidance has trended a bit more conservative with how far west the marine layer extends inland, currently looking to make it just west of PHI. Sun and S/SW flow by morning will aid in dissipating this after sunrise.
SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/
High pressure and mostly dry conditions prevail Thursday and Friday. The main question for this forecast period will be temperatures, as a weak cold front is progged to move through on Thursday. Timing of the frontal passage and ultimate strength of the front will determine how warm temperatures get on Thursday, but guidance has trended slightly warmer, especially east of Philly as the front deteriorates. Temperatures max out in the upper 60s to low 70s on Friday.
Shortwave energy could linger overnight Thursday so an isolated shower or two could develop. Otherwise, precipitation doesn't arrive until late Friday night to early Saturday morning as another front approaches.
LONG TERM /SATURDAY THROUGH TUESDAY/
Unsettled conditions are expected for the bulk of the extended period. Weak ridging overhead on Saturday erodes through the weekend as a shortwave trough digs to the north. An associated cold front brings shower activity on Saturday and Sunday, but could fall apart before moving through completely, or stall in the vicinity. High pressure could briefly build in again on Monday before a second stronger cold front sweeps through to clean out the previous boundary.
AVIATION /19Z WEDNESDAY THROUGH MONDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Today...Light NW flow prevails for the most part today with VFR conditions expected, though a slowly encroaching seabreeze is bringing onshore SE flow to some of the eastern terminals.
Tonight...VFR conditions are expected to start but low cigs/fog are expected to develop with the marine layer as it moves inland. Guidance has trended more conservative with how far west the marine layer extends, so for now keep it east of PHI.
Conditions should improve shortly after sunrise.
Outlook...
Thursday through Friday night...Mainly VFR.
Saturday/Sunday...Sub-VFR conditions probable with increasing chances for showers.
MARINE
While winds are expected to remain below SCA, onshore flow could bring fog, potentially dense, to the near shore waters and inland late tonight. There is some uncertainty on if low stratus or fog is more favorable to develop, but will continue to monitor for potential of marine dense fog.
Outlook...
Thursday through Saturday...No marine headlines anticipated.
Sunday...SCA flag possible. Seas may build to 5 feet in some locations, wind gusts 20-25 kts possible. Rain showers likely.
PHI WATCHES/WARNINGS/ADVISORIES
PA...None.
NJ...None.
DE...None.
MD...None.
MARINE...None.
