Area Forecast Discussion National Weather Service Mount Holly NJ 927 PM EDT Mon Apr 15 2024

SYNOPSIS
A cold front will settle south and east of our area tonight.
High pressure builds in later tonight and lingers through Tuesday, before a series of fronts and low pressure systems affect the East Coast Wednesday through early this upcoming weekend.

NEAR TERM /THROUGH TUESDAY/
As of 925 PM, a weak cold front located across the I-95 corridor will gradually settle south and east into the overnight, with a wind shift to the northwest in its wake. Drier air will also be filtering in southeastward overnight. Some lingering showers and thunderstorms continue to shift off the New Jersey coast and that should be it for convection. Made some mostly minor adjustments to the hourly temperature, dew point, sky, wind and PoP grids based on the latest observations and trends.

As we go through tonight, the sky will continue to clear southeastward. The overnight lows will drop to the low/mid 40s for the N/W areas and around 50 for south NJ and Delmarva.

On Tuesday, upper level ridging will continue over the area as a surface high moves southeast from the Great Lakes. Fair weather is expected with a mostly sunny sky. high temperatures will be a little above average with highs in the upper 60s to low 70s for most spots. A decently dry airmass too with dew points in the upper 30s/low 40s. Winds will be northerly near 10 mph before becoming west to southwest in the afternoon. A sea breeze should develop with a wind more from the south closer to the coast in the afternoon.

SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/
Upper level ridging will slide eastward toward our region Tuesday night. This should limit coverage of showers despite a warm front approaching from the south. Lows in the upper 40s to low 50s.

On Wednesday, the shortwave ridge weakens ahead of the next closed low approaching from the west, leading to increasing chances for showers though the day. Thanks in large part to the warm front in the region, there will likely be a robust temperature inversion through the day, resulting in limited instability. Therefore, not expecting any thunderstorms at this time. Daytime highs will only be in the low to mid 60s.

The closed low and a trailing cold front approach the region Wednesday night into Thursday. Consequently, there are chances for widespread showers and thunderstorms in the Wednesday night/Thursday period. As far as thunderstorms, instability, especially surface based instability may remain limited through this period, so it is uncertain how widespread the coverage of storms will be. At this point, it appears as if we are likely to have widespread showers with some embedded thunderstorms, primarily late Wednesday night into Thursday morning, though there still remains quite a bit of uncertainty with the timing.

For the rest of the day Thursday, global guidance is showing the potential for a backdoor front arriving as high pressure off the coast of Maine interacts with a weak coastal low off the Delmarva seaboard that will spin off from the decaying parent cold front from the previous night. Resultant E to NE flow will help keep temperatures much cooler than earlier in the week.
Depending on how far south this backdoor front advances, temperatures to the north will be in the 50s with mid to upper 60s to the south.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
Tranquil weather should return again, albeit briefly, as the low departs our region Thursday night into Friday, before the next cold front approaches to start the weekend. At this point, the forecast has rain chances almost throughout this period (Friday night through Sunday), but it is unlikely to be a washout through the period, rather there remains uncertainty in the exact timing of the cold front. Once the cold front passes, we should have drying conditions.

AVIATION /01Z TUESDAY THROUGH SATURDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight...VFR. Lingering southwest winds 10 knots or less will become northwest to north. Some terminals should have the wind go light and variable. Moderate confidence.

Tuesday...VFR. Locally light and variable winds early, then north- northwest winds around 10 knots becoming west to southwest later in the day. A sea breeze may result in a more southerly wind mostly at KACY in the afternoon. Moderate confidence.

Outlook...

Tuesday night...VFR.

Wednesday through Thursday...There is a chance (50 to 60 percent) for sub-VFR conditions at times due to stratus and showers. The best chances for this looks to be overnight Wednesday night into Thursday morning.

Thursday night through Saturday...VFR, but a brief period of sub-VFR is possible (20 percent) especially Friday.

MARINE
A shower or thunderstorm around early this evening. Otherwise, winds and seas will remain below SCA levels through Tuesday.

Outlook...

Tuesday night through Wednesday...Winds and seas should stay below SCA criteria.

Wednesday night through Friday...SCA conditions possible for at especially over our northern ocean zones as winds and seas build.

Friday night through Saturday...Sub-SCA conditions.

PHI WATCHES/WARNINGS/ADVISORIES
