Area Forecast Discussion National Weather Service Mount Holly NJ 407 PM EDT Sun Jun 25 2023 .SYNOPSIS... An upper-level trough over the Mid-Atlantic will gradually lift offshore tonight. The next low pressure system will track across the Great Lakes Monday, pushing a cold front toward our area late day. As this low slides across our area later Tuesday into Wednesday, the cold front will cross our region. Weak high pressure may then settle near our area Thursday and Friday before another low pressure system approaches next weekend as it moves into the lower Great Lakes. && .NEAR TERM /THROUGH MONDAY NIGHT/... Summary...Very warm and humid conditions through the near term. Showers and thunderstorms remain mostly scattered through Monday morning. Thunderstorms then become widespread during the afternoon and evening hours on Monday when severe thunderstorms are possible with damaging winds and hail as the main threats along with a non-zero tornado threat. There is also some flash flood risk Monday into Monday night. For the remainder of Sunday and into Sunday night, scattered showers and thunderstorms are expected to continue. We have seen heavy downpours recorded at automated gauges and received reports of small hail and gusty winds around 40 mph. Isolated stronger storms capable of producing gusty winds of around 40 to 50 mph and small hail continue to remain possible through this evening. Heavy downpours may result in localized flooding, particularly in locations where multiple showers and storms pass over the same area. As we head later in the evening and lose daytime heating, the showers and storms will tend to weaken and many areas will dry out for a time. With a strengthening low- level jet across the area ahead of an eastward moving upper- level trough, some scattered showers and thunderstorms may re- initiate, particularly across northwest New Jersey and the southern Poconos. Otherwise, low temperatures are forecast to be in the 60s across much of the area. For Monday, an upper-level trough is forecast to be tracking across the Great Lakes and Ohio Valley. Plenty of moisture will be in place and therefore it will be humid once again, although plenty of boundary layer heating may result in the surface dew points lowering some. Areas of stratus may greet us to start the day, however that should lift and breakup through the morning into the afternoon. The heating combined with dew points around 70F will result in ample instability for showers and thunderstorms to quickly develop by midday, however these should initially be isolated to scattered. Deeper convection is forecast to develop to our west near a pre- frontal trough. The model forecast soundings indicate some discrete cells out that way should quickly consolidate into a convective line as it shifts eastward. An examination of model point forecast soundings indicate ample instability developing along with rather steep low-level lapse rates, and the mid level lapse are on the steeper side as well. The shear profiles are somewhat on the weaker side, however model soundings show some initial backed low-level flow with around 30 knots of shear. This would be enough when combined with strong forcing for ascent arriving for the risk for severe thunderstorms. Storms should organize into a line as it approaches our region with damaging winds and some hail the main threats. Given the backed near surface flow ahead of the line, cannot rule out some rotation within the eastward advancing squall line (QLCS) especially across Delmarva. CAM guidance shows convection quickly becoming linear, with even some hinting at strong outflow winds. Given the steep low-level lapse rates, downdraft instability (DCAPE) should be on the high side, which will enhance convective winds down to the surface especially associated with any forward surges in the line. With increased confidence in linear thunderstorm segments capable of producing damaging winds forming, the Storm Prediction Center now has much of our area south of the I-78 corridor in an Enhanced risk (level 3 of 5) for severe thunderstorms on Monday. Most rest of the area outside of the southern Poconos is in a Slight risk (level 2 of 5) for severe thunderstorms on Monday. While the convective line moves off the coast during the early evening, some additional convection may still move through although this should be weaker and less organized. Eventually as the environment becomes worked over, convection should be on the decrease overnight. In addition to the severe thunderstorm risk, areas of heavy rain look probable given precipitable water values forecast to be 1.50 to nearly 2 inches. This abundant moisture is an indicator for the potential for excessive rainfall. The Weather Prediction Center has most of our area in a Slight risk for excessive rainfall Monday. In addition, south to southwesterly flow may foster some training cells which would enhance the local flash flood threat. The rainfall is needed, however excessive hourly rainfall rates would locally enhance the flash flood potential especially in the urban areas. A caveat to this would be if the high rainfall rates only occur with a steady eastward moving squall line, as this will limit the duration of the heaviest rain. It will be very warm Monday especially if convection holds off longer and more sunshine can occur. Heat indices are forecast to top out around 90 degrees for much of the I-95 corridor especially, with even low to mid 90s in Delmarva. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY/... The short term period will look to remain rather unsettled overall. Occluding low pressure is expected to be located near/over the Great Lakes region to start the period as the cold front associated with it continues to approach. This cold front will look to pass through the region sometime during the Tuesday night to Wednesday morning time frame, though confidence on exact timing remains rather uncertain. Though guidance indicates this cold front may actually slow down or even stall some after crossing into our area, the main story of this boundary is that it will do little to offer us relief from the unsettled pattern we have been seeing. Even with the low pressure system north of the region Wednesday and the main boundaries offshore, stalling and continued occlusion keeps Wednesday unsettled as well. For Tuesday, the forecast will carry mainly likely and categorical chance PoPs as the front approaches. Warm air advection will continue over the region but should not be as pronounced as the day before. Regardless of this fact however, daytime heating and the overall pattern should allow for instability, showers and thunderstorms to be seen again during the afternoon and evening time frame. SPC currently has our CWA under a Marginal Risk. Highs will look to be in the low 80s across the region with dew points in the upper 60s to low 70s. Specific Humidity (Q) and Precipitable Water (PW) values will look to be well above climatology. For Tuesday night, the forecast will carry mainly likely and chance PoPs with PoP chance generally decreasing towards Wednesday morning; showers/thunderstorms and general thunder remains possible. Temperatures and dewpoints in the mid-60s across the region are anticipated. Q/PW values will look to be well above climatology. For Wednesday, mainly chance PoPs across the region increase to mainly likely and categorical north of Delmarva. Daytime heating and the overall pattern may allow for instability, showers and thunderstorms to be seen again during the afternoon and evening time frame. High temperatures in the upper 70s to low 80s accompanied by dewpoints in the mid to upper 60s are anticipated. Q/PW values will look to be well above climatology. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... The long term forecast looks to be more of the same, i.e., an overall unsettled pattern continuing. In the upper levels the ensembles support an upper level trough/trough axis over the eastern CONUS Wednesday night lingering over the area and offshore through the Saturday night time frame, though looking to break down and decrease in magnitude with time. Weak high pressure to our southwest maybe present over TN/VA/WV/NC Thursday, but low pressure to the north/northeast coupled with upper level troughing/shortwave energy may continue to keep the area unsettled. This will also be the story for Friday and Saturday at this point, though no major synoptic fronts look to be in the forecast, just continued shortwave energy and troughing. The forecast will carry chance and slight chance PoPs every period during the long term. The greatest chance for PoPs will be during the afternoon periods for each day as daytime heating will lead instability/shower generation and the possibility of thunderstorms. Temperatures will look to be around average during the duration of the long term as will PW/Q values. && .AVIATION /20Z SUNDAY THROUGH FRIDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas... Through 0Z...Widely scattered showers and thunderstorms will continue across the area this afternoon before diminishing in coverage and intensity early this evening. Best chance for seeing storms at any of the TAF sites will be for PNE, TTN, RDG, and ABE with a lower threat for the sites farther south. Sub VFR conditions possible in any storms with visbys potentially getting down to around a mile due to +RA. Winds generally S to SW around 5-10 knots but there will be variability due to storms and associated outflow boundaries. Also, any storms could briefly produce winds to 30 knots or higher. Moderate confidence overall but low confidence regarding whether any individual TAF site will see a storm with associated winds and restrictions. Tonight...SW flow 5-10 kts plus lingering clouds may keep patchy mist/fog from forming, but it will be a concern. Evening will see most convection dwindle, but next system approaching then looks to see more SHRA and possibly even TSRA redevelop overnight with best chances for RDG and ABE. MVFR likely in any SHRA overnight. Moderate confidence overall. Monday...Restrictions to MVFR possible in the morning with AM round of showers/storms that looks to mainly affect areas north of PHL. Otherwise mainly VFR through early afternoon. Then more thunderstorms expected by late afternoon into the evening that could potentially take the form of a squall line with damaging wind gusts of 40 to 50 knots. Low confidence still on these details though. Southerly winds 10-15 knots during the day, diminishing to 5-10 knots at night. Outlook... Tuesday and Wednesday...VFR, however some times of sub-VFR conditions possible with some mainly afternoon and early evening showers and thunderstorms. Southerly winds around 10 knots, becoming westerly Wednesday 10 knots or less. Low confidence. Thursday and Friday...Sub-VFR conditions possible with some scattered showers and thunderstorms, mainly in the afternoon and early evening, otherwise VFR. Also, storm chances/coverage lowering compared to early in the week, especially by Friday. Low confidence. && .MARINE... No marine headlines expected through Sunday night. Scattered showers and thunderstorms which could result in brief periods of heavy rain. South/southeasterly wind 10-15 knots. Seas 2-3 feet. On Monday, Small Craft Advisory conditions are possible as seas begin to build to 3 to 5 feet with gusts up to 25 knots possible. Some showers and thunderstorms. Thunderstorms may produce strong winds later Monday afternoon and evening, and therefore Special Marine Warnings may be needed Outlook... Tuesday/Tuesday Night...SCA conditions likely. S/SW wind gusts of 20 to 25 kts possible, seas 5 to 6 feet. Wednesday/Wednesday Night...SCA conditions possible as seas linger near 5 feet. Thursday/Thursday Night...No headlines expected. Friday/Thursday Night...SCA conditions possible as seas linger near 5 feet. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None. DE...None. MD...None.
