The local office's own words before the first event, 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 the first event at Aug 2, 4:01 PM EST, 39 minutes earlier.
Area Forecast Discussion...CORRECTED National Weather Service Mount Holly NJ 501 PM EDT Wed Aug 2 2017 .SYNOPSIS... A generally steady southerly flow will continue through the end of the week until a warm front approaches from the south late Friday, followed by a cold front that moves through Friday night into early Saturday. High pressure builds into the area Sunday. A low pressure system is expected to pass near or north of the area early next week. High pressure then builds back into the area toward the middle of next week. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... Numerous showers and thunderstorms continue to impact the area. Convection has already started to weaken late this afternoon across eastern PA and western NJ, where the airmass has been worked over from earlier activity. These showers and storms will decrease in coverage toward sunset though there could be scattered showers that linger through late evening, especially toward the Delaware Valley and I-95 corridor. Farther south and east across Delmarva and southeastern NJ, the airmass was still unstable as of 5 PM with storms remaining upstream. There threat of pulse severe and locally heavy rain will be present across these southeastern zones through about sunset. Coverage of convection may not be quite as extensive as it was farther inland earlier this afternoon as lift associated with an upper shortwave trough passes to our northeast. Partial clearing that occurs later this evening and overnight will allow for fog to develop as the ground remains wet and winds light. Most of the guidance does not indicate extensive fog, but it may be underdone. Although confidence is not particularly high, would not be entirely surprise to see at least patchy dense fog overnight into early Thursday morning. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/... The Mid-Atlantic region will remain downstream of a broad large- scale trough over Hudson Bay that extends southward through the Upper Midwest and Mississippi Valley. There will be a stronger shortwave disturbance embedded within the broad trough that is expected to progress eastward toward the Great Lakes region. With SW flow downstream of this system, a frontal boundary will remain stationary across the Midwest/Great Lakes region on Thursday. No significant changes in the airmass is expected by tomorrow. Accordingly, expect high temperatures on Thursday that are very similar to what was observed today and yesterday (generally 85-90F, except cooler near the coast and at higher elevations in NE PA and NW NJ). Daytime heating will once again destabilize the atmosphere, which should lead to convective initiation as early as late morning but more likely during the early to mid afternoon. BUFKIT forecast soundings from the NAM show a moderately unstable airmass at peak heating with MLCAPE between 1500-200 J/kg (similar to today) while MLCAPE values are not quite as extreme on the GFS (1000-1500 J/kg). Models show even less of a forcing mechanism on the synoptic scale than today as there doesn't appear to be an upper shortwave disturbance or even a surface trough to provide a source of lift or focus for convection. The main source of lift will likely be differential heating/terrain circulations across the higher terrain in E PA and NW NJ. Accordingly, chance PoPs were confined to west of the Fall Line. PoPs then decrease to slight chance farther east into I-95 and the coastal plain, although there could be a focus for additional storms along the sea-breeze front in NJ. Storms on Thursday will once again be slow movers, which could potentially result in locally heavy rainfall and poor drainage flooding or perhaps flash flooding. There is a limited potential for pulse severe wet microbursts during peak heating hours. && .LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/... For Thursday night into Friday, a generally steady southerly flow will remain across the area while a southwest flow aloft continues. The southerly flow will keep warm and humid conditions across the area, which will keep some instability across the area Thursday night into Friday. A couple of weak vorticity impulses will slide across the area with the southwest flow aloft. This combination of instability and lift from the vorticity impulses will keep a chance of isolated/scattered showers and thunderstorms Thursday night into Friday. By late Friday afternoon, a warm front may lift toward the area, ahead of an approaching cold front. The cold front is expected to move across the area late Friday night into Saturday morning. There will remain instability ahead of the frontal boundary, although it will weaken some overnight. Nevertheless, there will continue to be a chance of showers and thunderstorms overnight Friday into Saturday morning. PW values increase ahead of the front, so there could be some heavy rainfall overnight Friday into Saturday morning. The frontal boundary is expected to move offshore during the daytime morning hours Saturday. Behind it, drier and cooler conditions are expected for the remainder of Saturday, through Sunday night. For Monday into Tuesday, an area of low pressure is expected to lift near or to the north of the area, pulling a warm front, then a cold front through. The warm front is forecast to lift into the area early Monday, then the cold front is expected to move through overnight Monday into Tuesday morning. PW values could approach or exceed 2 inches during this time, which could lead to period of heavy rainfall. Behind the cold front, drier conditions are expected to build across the region as high pressure begins to build in from the west through Wednesday. && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Brief period of IFR in heavier showers and storms thru about 22-23Z for I-95 terminals and west, then through about 01-02Z farther east into MIV and ACY. VFR outside of storms this evening. Potential for fog development overnight, especially in fog prone terminals. Given how extensive the coverage of convection was/is this afternoon/early evening and the potential for at least partial clearing tonight, fog may be more extensive than currently indicated. Future TAF updates this evening could trend more pessimistic. Predominately VFR on Thursday. However, isolated to widely scattered storms during the afternoon could lead to localized/brief flight restrictions, especially across western terminals (RDG-ABE). Winds will be light/variable through tonight, then generally out of the S 5-10 kt on Thursday. OUTLOOK... Thursday night-Friday...Generally VFR. Chance of scattered showers or thunderstorms which may temporarily lower conditions. Friday night-Saturday...CIGS lowering overnight Friday into Saturday morning, improving during the day. Chance of scattered showers and thunderstorms which may temporarily lead to lower conditions Friday night into Saturday morning. South-southwest winds Friday night, becoming northwest gusting to 20 knots during the afternoon behind a cold front. Saturday night-Sunday night...Generally VFR. North-northeast winds 10-15 knots, diminishing overnight Saturday into Sunday morning. Winds becoming northwest then westerly. Monday...Lowering conditions with rainfall spreading across the area. && .MARINE... Winds and seas below SCA threshold. The threat of storms over the waters will continue thru about 02Z. Gusty winds may necessitate SMWs for the strongest storms. RIP CURRENTS... There is a low risk of rip currents through this evening. A similar setup is expected Thursday though it could approach moderate during the afternoon as southerly winds ramp up to 15-20 mph nearshore. An E-SE 8 second swell is expected to persist through tomorrow as well. OUTLOOK... Thursday night-Sunday night...Sub Small Craft Advisory conditions expected through the period. Winds may gust around 20 knots at times. A cold front is expected on Saturday with showers and thunderstorms possible. Monday...Conditions may approach Small Craft Advisory levels by the end of the day Monday into Monday night. && .EQUIPMENT... Both KDOX WSR-88D radar and TPHL terminal doppler radar are down this morning. KDOX, which is down due to planned maintenance. TPHL has been down since July 29. While there is still no estimated time to return to service, FAA technicians are expecting a part needed to fix the TPHL to arrive sometime today and technicians are working on KDOX. && .PHI WATCHES/WARNINGS/ADVISORIES...
