Area Forecast Discussion National Weather Service Mount Holly NJ 1228 PM EDT Sun Jul 27 2025 .SYNOPSIS... The front situated off to our south and west will lift back north as a warm front today, ahead of a weak cold front that will pass through Sunday night. High pressure returns for Monday and Tuesday, before another cold front passes through Wednesday into Thursday. High pressure returns for Friday into next weekend. && .NEAR TERM /THROUGH TONIGHT/... Low clouds and humid/mild air stagnant across many areas so far today. Clouds gradually thinning out thru the afternoon. Mostly S/E. light showers moving across the area will help stir things up (hopefully). Temps will recover quickly on the the limited sun returns. Light S/SW winds developing. Scattered tstms still possible later this afternoon. As we get into the late afternoon, increasing instability across the area with daytime heating will result in showers and thunderstorms developing through much of the remainder of the day. Likely and categorical pops will continue in the forecast. These showers and storms will be very efficient rain producers resulting in the potential for heavy rainfall. Storm motions look to be fast enough to keep the threat for flooding localized but if storms repetitively train over an area, the threat for flash flooding will be higher. WPC has a SLIGHT risk for much of the area with a MARGINAL risk for the southeastern portion of the region where the threat for training thunderstorms is slightly less. SPC maintains a MARGINAL risk for severe thunderstorms too with damaging winds as the primary threat. Convection looks to diminish later on this evening with the loss of daytime heating and as the cold front pushes through the region. Unfortunately, the cold front won't decrease temperatures too much. Lows tonight fall back into the low-mid 70s for most locations again tonight. && .SHORT TERM /MONDAY THROUGH TUESDAY/... Monday and Tuesday will feature dry conditions with a mostly sunny sky both days as broad high pressure builds into the region from the south. The more notable part of the forecast will again be the heat. Highs on Monday will mainly be in the upper 80s to mid 90s with highs on Tuesday in the 90s. Dewpoints will also be in the 70s both days, so it will be very humid. This will result in heat indicies around the region in the 90-102 degree range on Monday and Tuesday. Right now, there is borderline Heat Advisory criteria for parts of the area and there is not enough confidence currently to issue any headlines for the beginning of the week regarding the heat. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... On Wednesday, we see another day of the heat and very humid conditions. Wednesday looks to be the day with the highest heat indicies in this stretch of the heat and humidity. Temperatures will mainly be in the mid 90s with dewpoints in the 70s which will lead to heat index values in the 95-105 degree range. Most of the day Wednesday will be dry with clouds increasing. A cold front moves in late Wednesday or even Wednesday night bringing some showers and thunderstorm potential to the area. There are some signs for the potential for severe weather on Wednesday but there is still a great deal of uncertainty. One big part of the uncertainty is the timing of the front that has been pushed back later which would lead to less favorable conditions for severe weather. The threat for localized flash flooding during this timeframe will also need to be watched with moisture increasing and PWATs at times reaching over 2 inches. The current progression of the front keeps it slower which has it not moving through the area until midday Thursday and continuing to be located close to the area for the remainder of Thursday which keeps the potential for showers and thunderstorms through the day. Behind the cold front, a high pressure system builds into the Great Lakes which leads to drier conditions on Friday and Saturday with temperatures being as much as 5-10 degrees below average through next weekend. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. This afternoon... Low clouds hanging in there across the terminals with some thinning S/E. Light showers arriving for the Delaware Valley terminals for around 18Z/19Z. Gradual improvement thru the afternoon. VCTS will probably remain in the AMDs but confid in this is low. South to Southwest winds mostly around 10 knots. Low confidence. Tonight...Conditions improving to VFR after the departure of showers and thunderstorms later in the evening. West-northwest winds around 5 knots or less. Moderate confidence. Outlook... Monday through Wednesday...VFR. No significant weather expected. Wednesday night through Thursday...Sub-VFR conditions possible with a chance of showers and thunderstorms. && .MARINE... No marine headlines expected through tonight. Winds will become mainly southerly for the daytime hours today, around 10-15 knots. Following the passage of a front tonight, winds will turn to the west-northwest. Seas of 2-3 feet throughout the period. Ahead of the front, there will be showers and a few tstms across the waters early this morning and then again this afternoon and evening. Higher winds and seas near tstms are expected. Outlook... Monday through Thursday...No marine headlines expected as winds will largely remain below 20 kt and seas around 2 feet or less. Fair weather expected for Monday through Wednesday. Another chance of showers and storms are possible for Wednesday night into Thursday. Rip Currents... For Sunday, winds be southerly around 5 to 10 MPH. Breakers of around 1 to 2 feet are expected. Period will be 5 to 8 seconds. As a result, a LOW risk for rip currents is in place at all beaches. For Monday, winds turn northerly and then easterly around 5 to 10 MPH. Breakers remain around 1-2 feet. Period will remain 5 to 8 seconds. As a result, a LOW risk for rip currents is in place at all beaches. For specific beach forecasts, visit weather.gov/beach/phi && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None.
