The local office's own words before this special marine 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 special marine warning went out at Jul 21, 2:03 PM EDT, 7 minutes earlier.
Area forecast discussion, Jul 21, 2:03 PM EDT, 7 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 203 PM EDT Wed Jul 21 2021 .SYNOPSIS... A cold front will move through the region today before moving offshore tonight. High pressure will build across the region for Thursday and Friday moving offshore over the weekend. Another cold front will move through the area Monday night into Tuesday, stalling to our south. && .NEAR TERM /THROUGH THURSDAY/... Severe Thunderstorm Watch 385 remains in effect until 8 pm for the majority of the forecast area. Only Carbon and Monroe counties are not included in the Watch. Cold front over central Pennsylvania and into central New York continues to approach. A pre-frontal trough has developed ahead of it and is working its way through New Jersey. With outflow boundary that was over the area late last night into this morning having washed out, temperatures rose into the 80s and dew points rose well into the 60s and low 70s. CIN is gone. As a result, SB CAPE values range from 1000-1500 J/kg across the southern Poconos and far northwest New Jersey, and from 2500-3500 J/kg across the rest of New Jersey, southeast Pennsylvania, and Delmarva. Highest downdraft CAPE values are along southeast New Jersey and into Delmarva, ranging from 800-100 J/kg, and even portions of southeast Pennsylvania are over 500 J/kg. Mid-level lapse rates are around 6C, and low level lapse rates are over 7C, even approaching 8C towards Delmarva. Even PWATs are over 1.5 inches, indicating threat for heavy rain. With steep lapse rates, once storms develop, updrafts will intensify. Wet bulb zero heights are on or around 1000 feet, which are fairly low for this time of the year. Convection has initiated with the strongest storms over southeast New Jersey, and another area of storms moving into the Lehigh Valley and Berks county. Focus should be on portions of New Jersey mainly south of the Fall Line, and towards the coast. Another area of storms likely towards the Delaware Valley, including Philadelphia. Damaging winds and large hail primary threats, with locally heavy rain and frequent lightning also expected. Cold front moves through the region this evening. Behind the immediate passage of the cold front, there may be some northwest winds gusting 20-25 mph for an hour or so. The storms and the passage of the cold front will allow for much of the smoke and haze to dissipate. Thereafter, northwest winds diminish to nearly calm levels for the overnight. Skies become clear. Surface dew points drop into the 50s by daybreak. Thursday features what will likely be the nicest day of July, if not the whole year. High pressure builds into the Ohio Valley and 850 mb temps will be around 10C. High temps will generally be in the lower 80s, except for the upper 70s in the southern Poconos and northwest New Jersey. A drying northwest wind both at the surface and aloft will allow for mixing, and surface dew points will drop into the low 50s. && .SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/... High pressure continues to build east Thursday night. Lows once again in the 50s to the north and in the 60s elsewhere. && .LONG TERM /SATURDAY THROUGH TUESDAY/... The trough aloft moves offshore on Saturday as the surface high starts to settle over the western Atlantic and we see a surface trough develop over the Mid-Atlantic. Low pressure will pass to the north of the area on Monday, dragging a cold front through our area Monday night into Tuesday. The front may then stall nearby or just to the south of area. Several shortwaves will cross the region through the early part of the week, keeping us unsettled with chances for showers and thunderstorms. While there will be a chance for storms each day, the majority of the time it will be dry and we are not expecting it to be a total washout. Temperatures will be more seasonable with highs in the mid to upper 80s (cooler to the north). As we head into the early part of the week, the 90s may start creeping back in and dew points will be on the rise, returning us to a slightly muggier air mass. Behind the front, we should see dew points drop back down a little bit. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Rest of this afternoon (18Z-00Z)...MVFR VSBY in HZ will dissipate, and VSBY will become VFR. SHRA/TSRA with brief sub- VFR conditions in +RA, hail, and potentially damaging winds. Will carry TEMPO groups for convection until 21Z-22Z. W-NW winds less than 10 kt, except higher in TSRA over terminals. Gusts to 20 kt possible for a few hours behind immediate passage of cold front. High confidence in overall pattern, low confidence on timing of TSRA passing over a given terminal. Tonight (00Z-12Z)...VFR/becoming SKC. NW winds 5 kt or less. High confidence. Thursday (12Z-00Z)...VFR. NW winds less than 10 kt. High confidence. Outlook... Thursday...Mostly VFR. West to northwest winds around 5 to 10 knots. High confidence. Friday...Mostly VFR. Sub-VFR conditions possible in isolated showers and thunderstorms. Light west to northwest winds. High confidence with low confidence on storms reaching the terminals. Saturday...Mostly VFR. Sub-VFR conditions possible in showers and thunderstorms. Southerly winds around 5 to 10 knots. High confidence with low confidence on storms reaching the terminals. Sunday...Mostly VFR. Sub-VFR conditions possible in scattered showers and thunderstorms. Southwest winds around 10 to 15 knots. Moderate confidence. && .MARINE... Tonight through Thursday...In generally, sub-SCA conditions. Showers and thunderstorms into early this evening will result in VSBY restrictions in heavy rain, hail, and damaging winds. Storms end between 8pm-10pm. Winds turns NW tonight at 15-20 kt, but not expecting 25 kt gusts. NW winds diminish Thursday morning, and there is the potential for afternoon sea breezes Thursday afternoon. Seas 2-4 feet. Outlook... Thursday night through Sunday...Sub-Small Craft Advisory conditions are expected across the area waters. Scattered showers and thunderstorms on Saturday and Sunday may produce locally higher winds and waves. Rip Currents... This afternoon through Thursday...There is a LOW risk for the development of dangerous rip currents. && .TIDES/COASTAL FLOODING... There is the potential that high tide tonight on the tidal Delaware River may hit minor flooding again but should remain below advisory levels. Going into the Thursday and Friday evening high tides, some coastal areas could approach at least minor flood thresholds. The full moon is on Friday which will lead to higher astronomical tides Thursday and Friday, but there may also be enough of a down-shore component to the wind to push enough water back toward land to increase tidal levels, especially on Thursday. && .PHI WATCHES/WARNINGS/ADVISORIES...
