The episode as NWS PHI wrote it up.
Hurricane Dorian moved through the Bahamas on September 1, 2019. North of it, up the East Coast, enhanced seas and dangerous rip currents developed. Warm weather was present over the mid-Atlantic, making for a dangerous combination over the Labor Day weekend. Numerous rescues were reported by local beach patrols, including a fatal event in New Jersey.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Sep 1, 12:31 PM EST, 1 hour 14 minutes earlier.
Area Forecast Discussion National Weather Service Mount Holly NJ 131 PM EDT Sun Sep 1 2019 .SYNOPSIS... High pressure over southwestern Quebec moves east today and will be over the Canadian Maritimes late tonight. A cold front will approach on Monday and pass through the region Monday night. High pressure returns for Tuesday and Wednesday, and then another cold front moves through the region Thursday, followed by high pressure late this week and this weekend. Hurricane Dorian may approach the Mid- Atlantic by the middle of this week before moving out to sea. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... 600 AM...Expansive surface high currently is centered to our north over Quebec with ridging extending south through the mid Atlantic region. Meanwhile a relatively flat upper level trough sits off to our west with some mid and high level cloudiness beginning to spill into the area as moisture associated with this is starting to move in. Winds will slowly begin to veer to the southeast and eventually south to southwest through the afternoon. As we head into the day today, the aformentioned high shifts slowly east into the Canadian Maritimes and Atlantic Canada, however, its western extent will continue to influence our weather. As such, despite a fair amount of mid and high level cloudiness that will be around from time to time, the day should be mainly dry with forecast models continuing to back off on the threat of showers as ridging remains more dominant. For this reason, trimmed PoPs back farther and only mention slight chances for isolated late day showers near western CWA border from western Chester County north into the Lehigh Valley and the southern Poconos. Otherwise a dry day with relatively light E/SE winds and highs mainly in the 70s to low 80s. Humidity should also remain fairly low as the front continues to sit just to our south and west. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/... Upper disturbance moves through to our north and west tonight as upper level trough over the Great Lakes starts to sharpen up. This will help push a warm front north through the area. As the disturbance moves through there will be showers and storms mainly across central and western PA into upstate NY but the southern and eastern extent of these showers will likely clip at least N/W parts of the CWA from the Lehigh Valley into the southern Poconos by late tonight. A few rumbles of thunder will also be possible. Not expecting much, if anything, though over SE PA, NJ, and the Delmarva. Increasing cloud cover along with the warm front moving through will result in milder overnight lows...mainly in the mid to upper 60s except low 60s in the southern Poconos. && .LONG TERM /MONDAY THROUGH SATURDAY/... Low pressure passing to the north will drag a cold front through the region late Monday and Monday night. The axis of the mid-level trough will mainly be to the north, along with the strongest forcing. Highest PoPs, likely/low-end categorical, will be across the southern Poconos and into the Lehigh Valley as well as far northwest New Jersey. Going farther south, PoPs taper down to chance, and high chance PoPs will be in place for southern New Jersey and southeast Pennsylvania Monday evening. Southerly flow will usher an increasingly humid airmass with surface dewpoints in the mid to upper 60s, possibly around 70. This results in PWATs just under 2 inches. Surface-based CAPE values will be 1000-1500 J/kg, along with a Lifted Index around -5C. Showers and thunderstorms will develop ahead of and with the passage of the cold front. Thunderstorms will be capable of locally heavy rain and gusty winds. Patchy fog will develop after showers and thunderstorms end late Monday night. High pressure builds in from the west on Tuesday and moves offshore Wednesday. A hot and humid airmass will be in place with highs generally in the low to mid 80s, except for the upper 80s along the I-95 corridor from Trenton to Philadelphia to Wilmington, and for most of Delmarva on Tuesday, and then a3-5 degrees warmer on Wednesday. Surface dewpoints will be in the low to mid 60s Tuesday, and then in the mid 60s to near 70 on Wednesday. Max heat index values on Wednesday will be in the lower 90s. A cold front passes through Wednesday night with another round of showers and thunderstorms. High pressure then builds in from the west starting on Thursday. Regarding Hurricane Dorian, it remains too soon to determine potential impacts to Delmarva and southern New Jersey, as developments over the next couple of days will greatly impact how Dorian develops later this week. However, there are indications that Dorian may approach coastal North Carolina and Virginia by Thursday before lifting to the north and east and out to sea for the end of the week. Based on latest guidance, coastal areas could experience rough surf and dangerous rip currents. Wrap-around bands of precip may also spread back towards the mainland, but it is too soon to determine how much rain will fall in these areas. Gusty winds of 25-30 mph are also possible. High pressure then builds over the area for next weekend with dry and seasonal conditions. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Tonight...Isolated showers or thunderstorms are possible but mainly in the north (KABE/KRDG). Otherwise, VFR through this evening with low cigs developing overnight with MVFR conditions expected. SE winds 5 to 10 knots early, then around 5 knots late. Monday...Generally VFR, but sub-VFR in scattered SHRA/TSRA during the afternoon. Light SE winds becoming S around 10 knots by late morning. OUTLOOK... Monday Night...Generally VFR, but SHRA/TSRA in the evening with sub-VFR conditions. Patchy fog late at night with sub-VFR conditions possible. South to southwest winds 5 to 10 knots. Tuesday...Mainly VFR. South to southwest winds 5 to 10 knots. Wednesday...VFR. However, some mainly afternoon and evening showers and thunderstorms are probable with local restrictions as a front moves in from the west. Southwest winds around 10 knots, becoming northeasterly at night. Thursday...MVFR conditions possible with shower activity, and gusty winds, from Hurricane Dorian, especially MIV and ACY. && .MARINE... Sub-SCA conditions through today with east/northeast winds 10-15 knots and seas 2 to 3 feet. Seas build to around 4 feet tonight with southeast winds around 10 knots. OUTLOOK... Monday through Wednesday...Sub-SCA criteria. Scattered showers and thunderstorms are possible Monday afternoon and evening, then again Wednesday afternoon. Wednesday night through Friday...Increasing seas and gusty winds are possible as Hurricane Doria approaches from the south. Please maintain situational awareness with this system in the days ahead. Rip Currents... A long period (10 to 12 second) southeast swell will arrive along the coasts of New Jersey and Delaware today. The swell along with an onshore wind around 10 mph will result in a moderate risk for the development of dangerous rip currents. && .TIDES/COASTAL FLOODING... The high tides remain elevated with the current new moon phase. While astronomical tides will gradually begin to recede in the coming days, light onshore winds today will also help keep water levels elevated. As a result, spotty minor tidal flooding remains possible into the new week, especially with the astronomically higher evening/nighttime high tides. However, most indications are that any flooding should remain below thresholds needed to trigger an advisory. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None. DE...None. MD...None.
