FitzsimmonsWhat forecasters said that day
The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Jul 20, 10:35 PM EDT, 3 hours 57 minutes earlier.
Area forecast discussion, Jul 20, 10:35 PM EDT, 3 hours 57 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 1035 PM EDT Thu Jul 20 2023 .SYNOPSIS... A stationary front remains over the area through today before returning back north as a warm front tonight. A cold front then passes through the region on Friday. High pressure builds in from the west on Saturday then weakens and moves offshore Sunday night. A few weak disturbances may affect us early next week. && .NEAR TERM /THROUGH FRIDAY/... Severe Thunderstorm Watch #530 is now in effect until 5 am for most of southeast Pennsylvania, including Philadelphia, and parts of northern New Jersey. A line of severe thunderstorms is currently moving through western New York and western Pennsylvania. This system is on track to impact Berks county and the southern Poconos around midnight, and then the I-95 corridor, including Philadelphia and surrounding suburbs, and northern New Jersey around 2 am, and then eastern New Jersey thereafter. These storms are about 2 to 3 hours faster than previously forecast, and are faster than latest HRRR and 18Z NAM have indicated. Damaging winds are likely, as well as large hail. Heavy rain and localized flash flooding is also possible. Surface-based CAPE values are up around 1500 to 2000 J/kg along with 25 to 35 kt of 0-6 km Bulk Shear. By the time early Friday morning arrives, storms will have moved in with coverage potentially be relatively widespread for areas near and N/W of the I-95 corridor. By this time, the strongest upper level forcing should be just moving through with low pressure centered near Lake Ontario and the system's triple point over eastern PA with the warm front extending eastward through NJ and the cold front extending S/W into Maryland and Virginia. The overall evolution of the convection becomes a bit more uncertain beyond this time as initial shortwave aloft swings through to the north and east but the main upper level trough only chugs slowly east across southern Ontario into upstate NY. This means that the low at the surface and its associated fronts should be slow to move east as well. The upshot of this is that stormy weather is likely to continue through at least the first half of Friday as initial convection could even start to train for a time over eastern PA into northern NJ. Even as this first round should be moving out by around midday there could be more storms that develop in the afternoon. It's uncertain though how much instability there will be due to AM storms so the SPC keeps area in a MARGINAL risk for severe weather for Day 2 (starting 12z Friday) with a MARGINAL threat for excessive rain and flooding/ flash flooding also be indicated by WPC. By the time the system moves through by Friday evening with winds turning westerly and conditions drying out, think much of the area could see 1.0 to 2.0 inches of rain with locally higher amounts. Heaviest amounts should be in the north. Again, still some uncertainty on this so forecast will continue to be refined through the day today. The showers/storms should help keep temps cooler for Friday with highs mostly in the low to mid 80s except some upper 70s over the higher terrain where clouds are most likely to remain in place through the day. && .SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/... Cold front will be rapidly pushing off the coast Friday evening. Still a little uncertainty in timing so held some chance pops early but back them off below slight chance after 00Z. Otherwise, clearing, cooler and drying out Friday night. Lows overall will drop 3-5 degrees compared to Thursday night, with 60s across most of the region. High pressure slowly builds in Saturday and Saturday night. We'll see plenty of sunshine, which will help allow temps to rise back to near the same readings we're expecting Friday (mid-80s), but dew points will be 5-10 degrees lower, mostly in the low-mid 60s. This will result in a considerably more comfortable day compared to Friday. A weak secondary front passes Saturday evening, ushering in slightly cooler and drier air. This will help lows drop a few more degrees compared to Friday night, settling down into the upper 50s to low 60s overall, except still mid-upper 60s in the urban centers and near the waters. Otherwise, clear skies and light winds will prevail. Sunday will see continued mostly sunny skies as high pressure remains in overall control, thought it will be shifting off-shore with warm advection just beginning later in the day. Thus, expect highs to nudge back up a degree or two compared to Saturday, but dew points will do the opposite, so overall, another nice, dry day. && .LONG TERM /SUNDAY THROUGH THURSDAY/... High pressure will be firmly offshore by Monday, with a return southerly flow starting to nudge dew points back up, though they still remain in the 60s. Warmth will build ever so slightly, tempered by the potential for some afternoon clouds or even a stray shower or storm as an upper level shortwave moves toward us, but overall still dry. This pattern more or less continues Tuesday, with some morning sun followed by afternoon clouds and a stray shower/t- storm with another upper-level disturbance, but more dry than not for sure. By Wednesday, a warm front starts to lift back north of the region, decreasing the threat of isolated showers/storms as a ridge builds toward us, but also allowing temps and dew points to creep back up a few more degrees. Still not quite oppressive for this time of year, but more uncomfortable than the prior two days, with dew points mostly in the upper 60s and temps rising toward the upper 80s. Temperatures warm even further Thursday with afternoon highs in the low 90s for most and dew points creeping back into the low 70s. && .AVIATION /03Z FRIDAY THROUGH TUESDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas... Tonight...Mainly VFR this evening as initial showers and storms dissipate. Next round of showers/storms begin to move in from the west most likely after 6z with lowering cigs as well. This should result in sub VFR conditions occuring at all sites by around 09Z. Winds mainly southeast 5 to 10 knots. Moderate confidence. Friday...Sub-VFR in SHRA/TSRA in the morning, then another round of SHRA/TSRA with sub-VFR conditions possible in the afternoon. South winds 5 to 10 kt, becoming southwest to westerly by late day. Moderate confidence in morning restrictions, low confidence for the afternoon. Outlook... Saturday through Sunday night...VFR. W to NW winds 10 to 15 kt during the day, then LGT/VRB at night. High confidence. Monday through Tuesday...VFR overall. Scattered afternoon SHRA/TSRA possible. S winds 5 to 10 kt. Moderate confidence. Wednesday...VFR. SW winds 5 to 10 kts. Moderate confidence. && .MARINE... Sub-advisory conditions on the waters through today with winds around 10 kts easterly becoming southeasterly tonight. Waves 2-4 ft. A round of showers and thunderstorms with gusty winds and heavy rain possible late tonight and Friday morning, then again late Friday afternoon and evening. Outlook... Friday night through Wednesday...A prolonged period of sub-SCA conditions anticipated. No chance of showers or storms over the weekend, with only a slight chance Monday and Tuesday with mostly dry weather expected Wednesday. Winds will mostly be west to northwest 10-15 kts over the weekend, becoming southeasterly 10-15 kts Monday and Tuesday then southwesterly on Wednesday. Seas 2-4 ft. Rip Currents... Although there will be showers and thunderstorms Friday morning, and then possibly again Friday afternoon and Friday evening that could produce locally strong thunderstorms winds, the overall winds will be out of the south to southeast at 5 to 10 mph. There should be a medium period southeast swell up to 10 seconds. There is a LOW risk for the develop of dangerous rip currents, outside of thunderstorms, at New Jersey and Delaware beaches on Friday. On Saturday, winds turn to the northwest at 5 to 10 mph. A light easterly swell will be in place. Once again, there will be a LOW risk for the development of dangerous rip currents at New Jersey and Delaware beaches. && .PHI WATCHES/WARNINGS/ADVISORIES...
