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 Sep 9, 4:38 PM EDT, 1 hour 39 minutes earlier.
Area forecast discussion, Sep 9, 4:38 PM EDT, 1 hour 39 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 438 PM EDT Sat Sep 9 2023 .SYNOPSIS... A surface boundary will continue to linger over and near our region through Monday. A stronger cold front approaches Tuesday and looks to cross through the region Wednesday into Thursday. Surface high pressure builds in thereafter and holds influence over the region for the end of the week. && .NEAR TERM /THROUGH SUNDAY/... The weather pattern today remains the same as it has been for the past couple of days. A strong ridge is off the East Coast, while a trough over the Tennessee Valley continues to send shortwaves northward generally up the Appalachians. A larger scale trough around Hudson Bay extending southward into the Great Lakes will finally help lift the aforementioned trough northeastward across the Appalachians, while the offshore ridge gives way. All of this will allow a stationary front that has been hanging up to the west of our region to drift closer in on Sunday into Monday, with a couple weak waves of surface low pressure traveling along it. As we head through this afternoon, thunderstorms have been primarily focused on the sea breeze toward the NJ shore, but have been gradually building westward closer to I-95 with the aid of outflow boundaries from the earlier storms. RAP analysis suggest 2500-3500 j/kg CAPE across much of our area. However, with all of the low clouds this morning along with some cloud debris from earlier convection, instability overall across our area, particularly north and west of I-95, looks somewhat more limited than yesterday. We have warmed well into the 80s across the Delaware Valley on southeastward, and dewpoints outside of the Poconos for the most part are in the low to mid 70s, with another very warm and muggy day. For most spots though, this will be the first day we don't eclipse 90 degree high temperatures. Additionally, wind shear is a bit less today. While storms near the sea breeze, and particularly one drifting across Middlesex County this afternoon, have been locally severe, overall in most areas expect that storms will not be as strong as yesterday, with somewhat lesser coverage as well, especially back west across PA and northwest NJ. Most model guidance suggests that thunderstorm activity will diminish 6-9 PM with the loss of daytime heating. Low clouds and areas of fog may settle in once again overnight. However, a more prominent shortwave lifting north overnight into early Sunday morning may result in showers and sub-severe embedded thunderstorms drifting in from the west across eastern PA into northwest NJ tonight. There is less consistency and agreement from the model guidance how much, if any of that makes it toward the I-95 corridor tonight, with areas south and east of there likely mainly rain-free through early Sunday morning. Meanwhile some isolated showers and storms may drift up across the Delmarva early Sunday as well. Sunday is looking like a cooler and cloudier day overall, though still warm and muggy with a very moist and unstable airmass in place. With the aforementioned diffuse stationary front trying to drift farther southeast into our area, along with a bit more shortwave energy passing by throughout the day on Sunday, expect overall forcing for showers and thunderstorms to be a bit greater than past days, while instability will be lower, resulting in perhaps more widespread precipitation but weaker storms. Highs may only be in the upper 70s to low 80s for most of the area, but dewpoints will still be generally in the low 70s. Enough wind shear will exist still to support a 'marginal' risk for severe thunderstorms, with the primary threat being damaging winds, but would not rule out isolated large hail either. While the sea breeze could still be active around midday, models suggest thunderstorms will become more focused perhaps near or just northwest I-95, with a threat for flash flooding where any storms persist. Expect showers and t-storms will diminish in intensity and coverage once again as we approach sunset. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/... The short term will look to begin Sunday night with a stationary surface boundary still lingering over the region. Guidance suggests this boundary will continue to linger over the region through Monday and possibly even into the time frame of Monday night. During the same time frame however, stronger low pressure and associated fronts will be developing west of region and moving eastward. These features will look to force the surface boundary offshore of the region possibly by the time frame of Tuesday morning. Following the surface boundary movement offshore, the cold front to the west will continue to approach our region through Tuesday. This pattern supports continued stormy conditions across the region through much of the short term. For Sunday night, likely chance PoPs throughout the region to begin the period are included in the forecast. PoPs decrease with time towards Monday morning as shower/thunderstorm potential decreases. Widespread fog development is possible in the second half of the period and should be expected near 12z Monday. WPC maintains the I-95 corridor and areas northwestwards of it outlooked for a SLIGHT/MARGINAL risk of excessive rainfall for the period. The environment supports showers/thunderstorms which will be capable of producing heavy downpours which may lead to localized flooding. For Monday, fog may linger for a short period after 12z. Chance PoPs are included through the period as the surface stationary front lingers. Will increase PoPs in the afternoon as shower/thunderstorm potential increases due to access to daytime heating. For the overnight period, fog may develop across the region once again as we linger with moist conditions and airmass. For Tuesday, cold front from the west will continue to approach the region. Despite surface boundary offshore, shortwave energy may linger which may again allow for the development of showers/thunderstorms. Shower/thunderstorm potential will of course be greater in the afternoon due to daytime heating driving convection; will increase PoPs in the afternoon. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... A cold front will look to continue to approach the region Tuesday night and be either on our doorstep or beginning to cross through the region Wednesday morning. Though the cold front may slow down some while crossing the region, it will look to be offshore by Thursday morning. Surface high pressure will look to build in behind the front and will look to hold influence over the region thereafter through the end of the long term. Likely PoPs are included for Tuesday night and Wednesday, will bring them down through Wednesday night. No PoPs are included for Thursday through the end of the long term. WPC has highlighted the I-95 corridor and areas northwestwards of it in a MARGINAL risk for excessive rainfall Tuesday night into Wednesday. WPC maintains much of the region in a SLIGHT/MARGINAL risk for excessive rainfall Wednesday night into Thursday. Will continue to monitor the environment during these periods for supportive conditions of showers/thunderstorms capable of producing heavy downpours. We continue to monitor the track forecast for Hurricane Lee. While the hurricane is still forecast to make a northward turn with it remaining well east of our area, there still is some uncertainty. As of now, the main impacts look to be incoming large swells and the development of dangerous rip currents into our area during next week. && .AVIATION /21Z SATURDAY THROUGH THURSDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Today...Mainly VFR outside of scattered showers and thunderstorms. The thunderstorms will bring locally heavy rainfall along with brief MVFR/IFR conditions, along with gusty and erratic winds. Thunderstorms will be in the vicinity of I-95 this afternoon, then diminish this evening, while staying inland from the coast and mainly southeast of ABE/RDG. Elsewhere winds will be light east or southeast. Medium confidence. Tonight...Low clouds and patchy fog developing late tonight, mainly 06-12Z, with MVFR to even localized IFR conditions. Some occasional showers and even a stray thunderstorm possible between RDG and ABE overnight. Variable wind 5 knots or less. Medium confidence. Sunday...MVFR to IFR ceilings and VSBY with patchy fog early in the morning, improving to VFR mid or late morning but then showers and thunderstorms developing once again around midday or early afternoon, before diminishing toward evening. MVFR or IFR conditions possible near thunderstorms. Light southeast winds otherwise outside of any storms. Low confidence. Outlook... Sunday night...Sub-VFR. SHRA/VCTS likely for first half of the period. Fog development in the latter half of the period may drive sites down to MVFR/IFR visibilities. Light and variable winds. Low confidence. Monday...Generally VFR, though fog in the morning may cause sub-VFR conditions to linger. SHRA/VCTS possible for the afternoon. W/SW winds around 5 kts becoming NW by evening. Low confidence. Monday night...Generally VFR before fog development in the latter half of the period may drive sites down to MVFR/IFR visibilities. Light and variable winds. Low confidence. Tuesday...Generally VFR, though fog in the morning may cause sub-VFR conditions to linger. SHRA/VCTS possible for the afternoon. S winds around 5 to 10 kts. Low confidence. Tuesday night...Sub-VFR with SHRA/VCTS. SE winds around 5 to 10 kts becoming westerly by morning. Low confidence. Wednesday...Sub-VFR with SHRA/VCTS. Westerly winds 5 to 10 kts. Low confidence. Thursday...VFR. NW winds 10 to 15 kts. Moderate confidence. && .MARINE... Conditions will remain below Small Craft Advisory criteria through Sunday. Some isolated thunderstorms, mainly inland and near Delaware Bay, will be possible each afternoon though. A southerly wind 10 to 15 kt today will decrease to around 5 kt later tonight, then increase to around 10 kt again but from the east-southeast on Sunday. Waves on most of our ocean waters are expected to be around 2 feet, with waves on Delaware Bay at 2 feet or less. Outlook.... Sunday night...No headlines expected. Monday...No headlines expected. Monday night...SCA conditions possible; seas may grow to 5 feet in some locations. Tuesday...SCA conditions possible; seas may grow to 5 feet in some locations. Tuesday night...SCA conditions likely; seas 5-6 feet. Wednesday...SCA conditions likely; seas 5-7 feet. Thursday...SCA conditions likely; seas 5-7 feet. Rip Currents... A southerly wind 10 to 15 MPH is expected for today along the coasts of Delaware and New Jersey. Breaking waves are forecast to be around 1 foot with an underlying long period east to southeast swell (around 10 seconds). There is a LOW risk of rip currents for today. A south to southeast wind around 10 MPH is anticipated for Sunday with breaking waves around 1 foot. An underlying very long period southeasterly swell (around 16 seconds) is forecast to arrive. However, we will keep the mention of a LOW risk of rip currents since the breaking waves should be relatively tame. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None. DE...None. MD...None.
