Area Forecast Discussion National Weather Service Mount Holly NJ 308 PM EDT Sat Aug 12 2023 .SYNOPSIS... A cold front arrives into our area later tonight then settles south and eastward Sunday. A warm front then arrives later Monday with a stronger cold front crossing the area Tuesday. High pressure then builds in Wednesday into Thursday. The next cold front is scheduled to move through later Friday with high pressure arriving for Saturday. && .NEAR TERM /THROUGH SUNDAY/... Scattered showers and thunderstorms have formed early this afternoon in response to a passing shortwave causing lift in a very warm and unstable airmass. The best chance for convection should be mainly north of a ACY to ILG line. There will be two shortwaves passing through the region, one during the late afternoon, then a second shortwave overnight which will likely bring more convection through the region between 00Z and 06Z. This second batch of storms likely has less instability to work with, but an isolated severe storm can't be ruled out overnight either. SPC has placed the Poconos and Sussex county NJ in a Enhanced Risk of severe thunderstorms for this afternoon and evening, and a Slight Risk across northern NJ into the Lehigh Valley. Locally heavy rain remains a risk, but primarily in the far north, and storm motion should generally keep rainfall relatively limited today, with training the most likely reason to get any flooding. The cold front from Saturday night will largely wash out across the region Sunday morning, eventually departing offshore late Sunday. Given westerly flow, the seabreeze won't make it too far inland. Otherwise, another warm and humid day on Sunday with temperatures climbing into the upper 80s/low 90s with dewpoints in the upper 60s/low 70s. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... Increasing more humid along with a period of showers and thunderstorms. A trailing front which continues to look weak and potentially even dissipating across our area may still focus a shower or thunderstorm Sunday evening mainly across southern Delaware. Otherwise, clouds should persist through the night. As we go through Monday, it looks to turn more active again. An upper-level trough is forecast to gradually shift eastward from the Midwest and Great Lakes. The guidance is in decent agreement that this trough has a positive tilt as it shifts eastward. Downstream moisture and thermal advections will assist in a more humid air mass working northward across our area especially as a warm front moves in. While a shower or thunderstorm is possible with the uptick in moisture/thermal advections and incoming warm front, the forcing overall looks on the weaker side initially. Our attention then turns to a stronger shortwave that ejects out ahead of the main through and moves across our area Monday afternoon and evening. This shortwave could be convectively enhanced with an accompanied strengthening low-level jet. Showers and thunderstorms should be on the increase associated with this feature and with some increase in shear, convection may organize into a cluster/MCS with some potential for locally strong/damaging winds. The magnitude of the severe thunderstorm threat will depend on the degree of instability, timing and low to mid level lapse rates. The greatest instability will be south of the warm front. The timing overall looks to be later Monday afternoon and Monday night for the greater chances for showers and thunderstorms. A expansive plume of 2+ inches of precipitable water is forecast to be in place Monday ahead of the upper-level trough and cold front. The intersection of an initial southwesterly low-level jet with a northward moving warm front may enhance locally heavy rainfall especially where convection becomes more organized later Monday afternoon and Monday night. While there continues to be some flash flood threat especially in areas that have been wet the last few weeks, the placement of the warm front will be key as instability to its north looks to be minimal. The convection should tend to settle down overnight Monday night as the main shortwave shifts eastward. As low pressure tracks to our north though, a cold front looks to cross our area Tuesday. While Tuesday should be trending drier as time wears on, still cannot rule out some lingering convection until the cold front clears the coast and then there is also the positively tilted upper-level trough arriving. The better drying looks to take place Tuesday night as the precipitable water values drop significantly and the trough aloft weakens. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... Summary...Cooler and less humid to start but then becoming warmer and more humid again. Synoptic Overview...The tailend of a weakening upper-level trough is forecast to be sliding across our region Wednesday. The flow aloft in the East then turns more zonal into Thursday before the next upper-level trough across the Midwest and upper Great Lakes shifts eastward. Some guidance shows this trough taking on a negative tilt as it lifts across the Northeast Friday then well to our north Saturday. At the surface, high pressure builds in Wednesday before shifting offshore Thursday. A warm front may lift northward across our area later Thursday, followed by a cold front later Friday. Surface high pressure then arrives for Saturday. For Wednesday and Thursday...As the tailend of a weakening upper- level trough shifts across our area Wednesday, surface high pressure is currently forecast to build in. This will deliver a cooler and drier air mass therefore dew points will be in the more comfortable range. This looks to be short in duration though as high pressure shifts eastward, with a return flow setting up into Thursday. Well ahead of an upper-level trough in the Midwest, a warm front is forecast to lift across our area during Thursday. This will usher in higher dew points as low-level warm air and moisture advections increase. Cannot rule out a shower or thunderstorm with the warm front, but overall forcing looks weak and we then await for the cold front to arrive. Temperatures Thursday are forecast to be several degrees warmer than Wednesday and it will also be turning more humid. For Friday and Saturday...The details during this time frame will depend on the timing and amplitude of an incoming upper-level trough. Some guidance shows this trough taking on a negative tilt which typically strengthens the wind fields and also the forcing for ascent. This upper-level feature will drive surface low pressure to our north, however an associated cold front is currently forecast to cross our area later Friday. The magnitude of the shear and instability will determine the extent of convection ahead of and with the incoming cold front. This upper-level trough looks progressive therefore it lifts to our north into Saturday with high pressure at the surface to build in. It will be very warm and humid ahead of this cold front. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Through 00Z this evening...generally VFR. Widely scattered thunderstorms will briefly drop vsby and cigs to MVFR levels. Brief intervals of IFR are possible with scattered stronger thunderstorms most likely to affect the Lehigh Valley, Poconos, and northern NJ. Winds SSW increasing to around 10 kts with gusts up to 20 kts. Tonight...generally VFR, but with brief intervals of MVFR and possibly IFR vsby with scattered stronger thunderstorms. Again, best chance of impacts is in the Lehigh Valley, Poconos, and northern NJ. Winds mainly southerly around 5 kts. Sunday...VFR. Westerly winds around 10 kt. Outlook... Sunday Night...VFR overall. Winds becoming light and variable. Moderate confidence. Monday...A period of sub-VFR conditions, especially later in the afternoon and at night with some showers and thunderstorms. Light and variable winds becoming southeast to southwest around 10 knots. Low confidence. Tuesday...VFR overall. A few showers and thunderstorms are possible. Southwest to west winds increasing to 10-15 knots with gusts up to 20 knots, then diminishing to less than 10 knots at night. Low confidence. Wednesday and Thursday...VFR. Northwest to west winds 5-10 knots Wednesday, then southerly 5-10 knots Thursday. Moderate confidence. && .MARINE... Conditions will remain below Small Craft Advisory levels through tonight. Winds will be southerly at 10-15 kts with a few gusts up around 20 kts. Seas will be 2-4 ft. Main concern will be potential gusty thunderstorms this afternoon into tonight, with the highest risk over the waters north of Atlantic City NJ. Sunday...No marine headlines expected. Southwest winds around 10-15 kt. Seas 2 to 3 feet. Outlook... Sunday night and Monday...The conditions are anticipated to be below Small Craft Advisory criteria. Some thunderstorms expected later Monday. Tuesday through Thursday...The conditions are anticipated to be mainly below Small Craft Advisory criteria. Rip currents... Through this evening, southerly winds 10 to 15 mph with gusts up to 20 mph with breaking waves of 1 to 2 feet. There will also be a medium period southeast swell. As a result, there is a LOW risk for the development of dangerous rip currents at the New Jersey and Delaware beaches. On Sunday, winds remain parallel to the coast with south to southwest winds of 10 to 15 mph with gusts up to 20 mph. Once again, there will be a medium period southeast swell. There is a LOW risk for the development of dangerous rip currents at New Jersey and Delaware beaches. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None. DE...None. MD...None.
