Area forecast discussion, Jul 20, 4:11 PM EDT, 16 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 411 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/... The main story in the near term remains the potentially hazardous weather overnight into Friday. As of around 4 PM Thursday, the front remains stationary across the southern part of the area with weak, transient high pressure still to our north. Temps have risen into the 80s across most of the region with some upper 70s where showers and storms have developed. North of the front, over most of PA and NJ, dew points are in the upper 60s while they are still mainly in the low to mid 70s across southern New Jersey and Delmarva. We continue to see isolated to scattered convection, mostly near and south of the I-95 urban corridor. These are largely the result of diurnal heating and low-level convergence along the boundary. Most of this convection should once again dissipate as we lose daytime heating with the approach to sunset. This will result in a lull in the activity until later in the overnight hours. Our attention turns to our west as a developing low continues moving eastward across the lower Great Lakes driven by a potent disturbance in the upper levels that will start to take on a neutral to negative tilt. As the system approaches, warm front will continue to lift back northward into the CWA. Main concern looks to be after midnight as strong convection starts to approach from central PA and upstate NY. The overall trend in the latest set of CAM guidance has been for this to arrive earlier. However, it should be noted that there are still differences in the models regarding the timing, strength, and evolution of this system and its associated convection. Most likely scenario though is that storms begin moving in from the west over eastern PA beginning roughly in the 2-4AM timeframe....likely in the form of clusters or a squall line. Concern is that, as already alluded to, dynamics with this system will be strong with NE PA becoming situated between the right entrance region of an upper jet to the north and the left exit region of an upper jet approaching from the west with 500mb 12 hour height falls of 40-60+ meters. Deep layer shear in this area should also be around 30 to 35+ knots. Limiting factor for severe weather though will be timing at night which could limit the amount of instability and also result in more of it not being surface based. Still though, think that the strong dynamics could be enough to overcome this and the SPC has the area most northwestern portion of our area in a SLIGHT risk with areas slightly southeast that are near and immediately northwest of the I-95 corridor remaining in a MARGINAL risk for severe weather for the overnight period (to 12z Friday). The primary threat with these potentially severe storms would damaging straight line wind gusts. However, model soundings do indicate some significant veering of the low-level winds resulting in curved hodographs although the speeds are bit slow. This does indicate though that the threat for a weak tornado or two, particularly if embedded in a QLCS line, cannot be completely ruled out. Additionally, PWATs will also be around 1.75 to 2.0 inches so this same area will also be at risk for excessive rainfall and localized flash flooding by the latter part of the overnight period as the convection moves in and could produce very heavy downpours. By the time we get to early Friday morning, 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 /20Z THURSDAY THROUGH TUESDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas... Through today....Mainly VFR conditions today. A few isolated showers/storms possible in the afternoon that could cause brief restrictions so will handle these with VCTS/amendments as any approach the terminals. Winds mainly southeast 5 to 10 knots through the evening. Moderate confidence. 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... A light northeast wind this morning is forecast to become southeast by the evening. A southerly wind on Friday is expected to increase to 10-15 MPH. Breaking waves are anticipated to be around 2 feet along the coasts of Delaware and New Jersey both today and on Friday. There should be a medium period east to southeast swell, with an underlying long period (around 13 seconds) swell from the same directions. Due to the light wind and relatively gentle wave action, we will carry a LOW risk of rip currents for both days, even with the presence of the underlying long period swell. && .PHI WATCHES/WARNINGS/ADVISORIES...
