NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Aug 12, 8:47 PM EST, 3 hours 29 minutes earlier.
Area Forecast Discussion National Weather Service Mount Holly NJ 947 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/... Severe Thunderstorm Watch 638 remains in effect for northern New Jersey, the southern Poconos, and the Lehigh Valley until midnight tonight. A second round of showers and thunderstorms is trying to get going, however, with loss of diurnal heating, the atmosphere has stabilized and storms are not nearly as strong as they were earlier. Surface-based CIN values are in excess of 100 J/kg and surface-based CAPE values are generally 500 to 1000 J/kg. However, 0-6 km Bulk Shear should rise to 40 to 50 kt as that line of showers and thunderstorms approaches from the west. There is still the potential for severe thunderstorms, but the Storm Prediction Center has downgraded the northern portion of the forecast area from an Enhanced Risk to a Slight Risk. Cold front moving through the Ohio Valley will slowly work its way east, and should cross the region sometime after sunrise Sunday morning. A westerly breeze will develop by afternoon, with winds generally 10 to 15 mph with gusts up to 20 mph. Given westerly flow, the seabreeze won't make it too far inland. Humidity levels will lower throughout the day due to mixing from the westerly flow. Temperatures will be seasonably warm, topping off in the mid to upper 80s to around 90 in some spots. Surface dew points will start out in the upper 60s to low 70s in the morning, but will lower to the low to mid 60s in the afternoon. && .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 /02Z SUNDAY THROUGH THURSDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Tonight...Overall, VFR initially. SHRA and TSRA will affect the terminals this evening. General timeframe will be: KRDG/KABE from 00Z to 04Z, KTTN/KPNE/KPHL/KILG from 02Z to 06Z, and KMIV/KACY from 03Z to 07Z, though chances will be lower at KMIV/KACY. After the storms end, there is a chance for fog/stratus with at least MVFR conditions, though conditions may be IFR or lower, depending if heavy rain falls at or near a given terminal. S winds 5 to 10 kt, become LGT/VRB. Low confidence. Sunday...VFR after 13Z. Westerly winds 5 to 10 kt, increasing to 10 to 15 kt with 20 to 25 kt gusts in the afternoon. Moderate confidence. 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... Severe Thunderstorm Watch in effect for ANZ450 until midnight tonight. 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 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... Winds generally remain parallel to the coast with south to southwest winds of 10 to 15 mph with gusts up to 20 mph on Sunday. There will be a medium period southeast swell. There will be a LOW risk for the development of dangerous rip currents at New Jersey and Delaware beaches on Sunday. On Monday, a light onshore flow will develop, though winds turn south in the afternoon at 5 to 10 mph. There will be a medium period southeast swell. There will be 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.
