MLBWhat 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 Aug 15, 3:11 PM EDT, 1 hour 46 minutes earlier.
Area forecast discussion, Aug 15, 3:11 PM EDT, 1 hour 46 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 311 PM EDT Tue Aug 15 2023 .SYNOPSIS... A cold front will continue to cross the region tonight. High pressure builds in for Wednesday and Thursday. Another cold front is scheduled to move through the region Friday. High pressure to build in and hold firm for the weekend. && .NEAR TERM /THROUGH WEDNESDAY/... This evening...Severe thunderstorm Watch is in effect until 900 PM for southern/central NJ, metro Philadelphia and our Delmarva counties. These outlined areas have heated up greatly so far today while the northern areas have remain mostly cloudy. The decent CAPE values and good shear should promote tstms which will move mostly W to E across the region this evening. Damaging winds and hail are possible with a small possibility of a tornado too. The cells appear to be moving at a decent clip so far, so the flooding threat looks lower than past events. Still some localized issues possible however. Pay attention to updates/warnings over the next several hours. Tonight...After the severe weather threat ends, low level moisture and weak winds will lead to times of light showers and fog overnight. Conditions will be lower in areas that receive rains this evening. Lows will be in the mid/upper 60s mostly. Wednesday...The front and weak low pressure area will have moved offshore by morning, but there isn't a strong push of drier air behind it. The upper trough lingers across the area. Overall, precipitation coverage will decrease later tonight and there isn't much forcing for rains on Wednesday. We'll have a dry fcst attm but clouds and some morning fog are expected. After low clouds diminish, partly sunny skies and warm/humid conditions expected. Highs will be in the mid 80s most spots and dew points a bit drier than today, but still in the upper 60s/low 70s most areas. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... Brief upper height rises occur Wednesday night into early Thursday ahead of an approaching deep upper trough. A cold front will remain stalled out off the coast while a surface low tries to develop along it off to our southeast. Some vorticity advection will slide through while we remain between two systems, and a few showers may try to sneak on shore across the southern half of NJ as the stalled front pushes back northwest as a warm front, and also further northwest into the Poconos. Included some slight chance mentions of precip for these areas on Thursday afternoon but don't expect coverage to be all that widespread. Highs Thursday will be in the mid to upper 80s and southerly flow will hold dew points in the low 70s, so it will still feel quite muggy. The better chance (though still relatively low) for precip comes overnight Thursday into Friday morning as a cold front extending south from a low across Ontario passes. Most guidance has it arriving in the later overnight hours Thursday night, though the NAM holds it back until later on Friday morning. Either way, despite the higher dew points, not expecting any severe weather with this frontal passage with the unfavorable overnight timing. Guidance isn't all that excited about overall precip coverage either, so doesn't appear that this will be a significant widespread rain with the front. Lows should dip into the upper 60s/low 70s on Thursday night provided the timing of the front doesn't speed up at all. Into Friday, drier and cooler air works in (dew points may even drop to the 50s by afternoon) with northwesterly flow. It will likely be a bit gusty in the afternoon as a somewhat deep and dry boundary layer will be able to tap into 20-30 knots winds around 850 mb, and this will also aid in mixing out dew points as well. Some lingering cloud coverage in the morning will erode for the afternoon as broad high pressure builds across the Ohio Valley and will dominate the pattern for the rest of the day Friday and into the weekend as well. Highs will be cooler on Friday with readings in the low to mid 80s. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... In the upper levels, the long term period will look to begin Friday night with a trough just north of northeast CONUS and a ridge over the central CONUS. With time, the trough will push eastward as the ridge builds and becomes a large and dominate feature over the central CONUS. There is overwhelming support among the ensembles and deterministic guidance that this large ridge will hold firm for the long term; the period should be relatively quite weather wise for the most part. At the surface level, this upper level pattern will correspond to high pressure building in Friday night and holding strong influence over the region for the weekend and thereafter. The surface high will look to migrate eastward some with time, possibly sagging southward some for the Sunday through Monday time frame. This may allow for some shortwave energy to migrate and penetrate over the region, but for now no precipitation is anticipated as the upper level ridge and surface high pressure hold firm. No PoPs are included throughout the long term period forecast today! Temperatures will look to run right around average Saturday and Sunday, perhaps slightly above average for Monday and Tuesday. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Thru the evening...Scattered showers/tstms expected mostly Delaware Valley and south NJ sites. Lower (non-zero) changes for KRDG/KABE. IFR possible in tstms if over terminal. Mostly VFR outside of rains. West to Northwest winds around 10 knots. Low- medium confid. Overnight...Once the showers/tstms end across the area, there will be plenty of low level moisture across the area. Low CIGS and fog are probable but the degree of how much it will affect flight conditions is a challenge. Winds will become N or NW overnight. Medium confid. Wednesday...Low clouds and fog may be slow to diminish, so reduced CIGS/VSBYS possible until 13Z/14Z. After that, VFR should prevail for the rest of the day. Winds will be West to Southwest at 5 to 10 knots much of the time. Medium confid. Outlook... Thursday...Predominantly VFR. Scattered showers may result in brief sub-VFR restrictions in the late afternoon into the evening. Southerly wind around 10 knots. Moderate confidence. Friday...Predominantly VFR. More scattered showers may again result in brief sub-VFR restrictions mainly in the morning hours. Westerly wind increasing to 10-15 knots with gusts to 20 knots. Moderate confidence. Friday night thru Sunday...VFR with mainly clear skies. High confidence. && .MARINE... Scattered showers and tstms will be across the waters for the rest of the afternoon and into the evening as a front and weak low pressure move through. Behind the front/low winds will shift around to N or NW later on. Overall, winds and seas will be below SCA levels but locally higher winds and seas in and near tstms are always a hazard. Fair weather is expected for Wednesday. Outlook... Thursday...No marine headlines expected. Southeasterly wind around 10 knots. Seas 2-3 feet. Friday...Small Craft Advisory conditions possible. Southwesterly wind 10-15 knots with gusts to 20 knots. Seas 4-5 feet. Friday night...Conditions are forecast to be just below SCA criteria. Seas mainly 3 to 4 ft with frequent gusts near 20 kts. Saturday through Sunday...No headlines expected. Rip currents... A south to southwest wind around 10 MPH is anticipated for today along the coasts of Delaware and New Jersey. Breaking waves should be around 2 feet with a long period (around 10 seconds) east southeast swell. The expected conditions suggest that there will be a LOW risk for the development of rip currents. A variable wind 5 to 10 MPH on Wednesday morning is expected to become onshore around 10 MPH on Wednesday afternoon. Breaking waves are forecast to be 1 to 2 feet with a medium period southeast to south swell. There is again a LOW risk of rip currents. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None.
