Local storm reports filed while the alert was in force, from inside its polygon or its counties.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Brookhaven, NY (KOKX), launched 12:00Z, 4.8 hours before the alert went out and 219 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

StaarmannWhat forecasters said that day
The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this flash flood warning went out at Jun 24, 10:30 AM EDT, 2 hours 17 minutes earlier.
Area forecast discussion, Jun 24, 10:30 AM EDT, 2 hours 17 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 1030 AM EDT Sat Jun 24 2023 .SYNOPSIS... An upper-level trough over the eastern states will gradually lift north and eastward through Sunday before shifting offshore. The next low pressure system will track across the Great Lakes Monday, pushing a strong cold front toward our area later Monday. As this low slides across our area Tuesday, a strong cold front will cross our region. Weak high pressure may then settle near our area Thursday and Friday, although another front may be draped to our north. && .NEAR TERM /THROUGH TONIGHT/... Latest analysis shows a warm front stretching east-west across the middle of the forecast area, with surface low pressure centered to our west in western Pennsylvania. A weak cold front lies to the west, extending southward from the low pressure. Aloft, a weakening closed low is over Lake Erie, moving very slowly eastward. A very moist air mass is presently over the region with dew points in the upper 60s and low 70s as of 10AM. One additional passing weak shortwave is resulting in batch of showers and thunderstorms pushing into southeastern PA as of 10AM. Mesoanalysis depicts little shear but already around 500-1000 MLCAPE already this morning as a result of the warm moist surface and cooler mid-level temps with the upper low nearby. Expect that this batch of precip will likely maintain itself with some rumbles of thunder as it pushes through. A weak cold front approaches this afternoon and the closed low slowly works its way toward us. As insolation maximizes coincident with forcing from the front, expect coverage of showers and storms to increase. These should not reach quite the same coverage as we saw on Friday, but still expect another day of scattered precipitation for the majority of the region. Localized precip totals should not be as high as we saw Friday given a bit more westerly flow and precipitable water values lowering a bit through the day. Our emergence into the warm sector should allow temps to warm considerably, however, with most of the area reaching the 80s, which will help spark the afternoon convection. With forcing waning quickly this evening behind the front and with a loss of insolation, expect showers and storms to wind down rapidly, with a mostly dry overnight. Patchy fog may be a concern where skies clear somewhat. Lows will be in the 60s for most. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... Summary...Very warm and humid with showers and thunderstorms especially each afternoon and evening, with it most widespread during Monday. Some strong to severe thunderstorms possible Monday, especially in the afternoon and evening, and there is also some flash flood threat. A weakening upper-level trough traversing our area Sunday should still support the development of some showers and thunderstorms, especially in the afternoon and early evening (not a washout however). The flow is forecast to be on the lighter side, therefore convection may be more of the pulse variety, and some guidance hinting that terrain and sea breezes may be the main trigger for convective initiation. Given the setup, configured the PoPs a bit more to reflect this idea. Locally heavy rain should occur as showers and thunderstorms should be on the slower moving side. It will be warm and humid with temperatures topping out in the low to mid 80s for many places. While the showers and thunderstorms should tend to weaken at night, a few showers may still linger especially across the northern areas given the lingering weakness aloft. As we go through Monday, the next upper-level trough is forecast to be tracking across the Great Lakes and Ohio Valley. The leading edge of this trough may take on some negative tilt as it closes in on the Mid-Atlantic Monday afternoon and evening. This would tend to enhance the forcing for ascent into our area with time. Plenty of moisture will be in place and therefore it will be humid once again. While cloud cover may be on the more widespread side, heating combined with dew points around 70F will result in enough instability resulting in showers and some thunderstorms quickly developing during the course of the day. A pre-frontal trough may initially organize storms near the lee of the appalachians, with the potential for a few rounds of convection working their way across our area. An examination of model point forecast soundings indicate ample instability developing along with steep low-level lapse rates. The shear profiles are somewhat on the weaker side, however some soundings show some initial backed low-level flow with at least 30 knots of shear. This would be enough when combined with strong forcing for ascent arriving for the risk for some severe storms. Storms may tend to organize into lines or clusters, with damaging winds and hail the main threats at this time. Convection may continue for a while Monday night given the incoming upper-level trough, although the atmosphere will become worked over eventually with a weakening trend expected. In addition to at least some severe thunderstorm risk, areas of heavy rain look probable given precipitable water values forecast to be 1.50 to nearly 2 inches. In addition, south to southwesterly flow may foster some training cells which would enhance the local flash flood threat. The rainfall is needed, however excessive hourly rainfall rates would locally enhance the flash flood potential especially in the urban areas. It will be very warm Monday especially if convection holds off longer and more sunshine can occur. Heat indices are forecast to top out around 90 degrees for much of the I-95 corridor especially, with even low to mid 90s in Delmarva. && .LONG TERM /TUESDAY THROUGH FRIDAY/... Summary...Additional opportunities for some showers and thunderstorms. Temperatures should be close to average. Synoptic Overview...An upper-level trough across the East through Wednesday may then gradually lift out Friday before the next upper- level trough starts to approach from the west. The initial trough will keep surface low pressure shifting out of the eastern Great Lakes to start and across the Northeast Tuesday and Wednesday. A cold front attached to this will work its way across our area Tuesday into Wednesday. Weak high pressure may then arrive nearby Thursday and Friday while a cold front lurks to the north. For Tuesday and Wednesday...An upper-level trough will settle across the eastern states. This will have surface low pressure with it that moves across mostly the Northeast. A cold front however looks to slide across our region Tuesday into Wednesday. The presence of this trough along with increased chances for some convection will keep temperatures down some. The details regarding the convection will depend on the timing of the large scale or even mesoscale forcing for ascent processes, and at this time range there is lowered confidence on these especially tied to intensity. There should be windows of opportunity where showers and some thunderstorms increase with surface heating combined with a surface front moving through. A humid airmass is forecast to still be in place, therefore some heavy rain is possible. The thunderstorm intensity at this range is less certain. For Thursday and Friday...The upper-level trough is forecast to still be overhead Thursday although it should be starting to lift northeastward. This will take surface low pressure to our northeast across New England. Despite the surface system departing Thursday, the presence of the upper-level trough should result in at least some chances for additional convection. The chances should be decreasing though especially into Friday as the main upper-level trough is currently forecast to be lifting to our northeast. Weak high pressure may then settle nearby, although a cold front may be lurking to our north as the next upper-level trough takes more shape well to our west. Given lower confidence at this time range, maintained PoPs no higher than the chance range. && .AVIATION /14Z SATURDAY THROUGH WEDNESDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas... Today through 00Z...Visibilities have improved and ceilings have lifted to MVFR and are expected to continue improving to VFR likely by 18z-19z. However, scattered afternoon SHRA/TSRA may return temporary VSBY/CIG restrictions, especially to the I-95 corridor on NW, from around 16z-20z. Expect a break in the precipitation through 00z. Tonight...Scattered SHRA/TSRA possible through 04z or so then dry conditions most of the night. Will have to watch fog potential, especially NW of I-95. Winds light and variable. Outlook... Sunday...VFR most of the time, however brief restrictions possible with any showers/thunderstorms in the afternoon and evening. Southwest to south winds 5-10 knots. Moderate confidence. Monday...Periods of sub-VFR conditions probable with showers and thunderstorms. Southerly winds 10-15 knots during the day, diminishing to 5-10 knots at night. Moderate confidence. Tuesday...Times of sub-VFR conditions with some showers and thunderstorms, especially in the afternoon into the early evening. Southerly winds 10-15 knots, diminishing to less than 10 knots at night. Low confidence. Wednesday...Sub-VFR conditions possible at times due to some showers and thunderstorms, mainly during the afternoon into the early evening. Southwest winds around 10 knots. Low confidence. && .MARINE... No marine headlines anticipated through tonight. A chance of showers and thunderstorms which could result in brief periods of gusty winds and lightning. South/Southeasterly winds around 10-15 kt and seas 2 to 4 feet. Outlook.... Sunday..The conditions are anticipated to be below Small Craft Advisory criteria. Some showers and thunderstorms possible, especially nearshore. Monday and Tuesday...Small Craft Advisory conditions possible. Some showers and thunderstorms. Wednesday...Small Craft Advisory conditions lingering especially on the ocean zones due to elevated seas. Rip Currents... There is a LOW risk for the development of dangerous rip currents for the New Jersey and Delaware beaches today and Sunday. Conditions should be similar on both days, with a southerly wind around 10 mph and breaking waves around 2 feet. There is expected to be a medium period south to southeast swell. There is the potential for some mainly afternoon and evening showers and thunderstorms. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None. DE...None. MD...None.
