NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jun 16, 8:38 AM EST, 3 hours 17 minutes earlier.
Area Forecast Discussion National Weather Service Mount Holly NJ 938 AM EDT Fri Jun 16 2023 .SYNOPSIS... Low pressure will move into the Mid Atlantic region today. This will bring a round of widespread showers and thunderstorms this afternoon. The low will drift to the northeast through Saturday with additional showers and storm expected. Strong high pressure developing across New England with a coastal low offshore of North Carolina and Virginia will result in breezy conditions and below normal temperatures into the middle of the week. && .NEAR TERM /THROUGH TONIGHT/... Just got done making some adjustments to the grids. Looks like an outflow boundary, stemming from the early morning convection over the Delmarva is now working northward through northern DE, southeast PA and southern NJ. PoPs were added to account for this feature. Then for later today, some adjustments were made to the back end of the expected convection. I trimmed the likely PoPs over the Delaware Valley/I95 corridor to chance in the 6 to 8 pm time frame thinking that the focus of the convection will be closer to the coast at this time. In other words, I sped the back-end up a bit. As far as the main event later today goes, the potential still exists for strong to severe thunderstorms. Looking at the synoptic setup, a positively tilted 500 mb trough is digging through the Great Lakes into western PA this morning. It will eventually take on a neutral tilt later this morning/afternoon. Strong positive vorticity advection during the morning with modest height falls will lead to strong synoptic lift during the day. Mostly clear skies during the morning should lead to destabilization fairly quickly over South Jersey and Delmarva. Cloud cover from a decaying MCS over western PA/eastern OH could limit destabilization over eastern PA and northern NJ. On the mesoscale, a weak cold front/surface trough will provide the trigger necessary to see showers and thunderstorms develop. The latest CAMs and their forecast soundings continue to indicate MLCAPE values in the 1500-2000 J/kg range with 0-6 km shear 30-40 kt. Forecast soundings indicate some veering with height in the lowest few thousand feet, but speed shear is overall lacking in the lowest levels with 850 mb wind only 20-25 kt. Some storm organization/a few discrete cells are possible as mean storm motion vectors have a line normal component to the boundary. Current thinking, though, is that we'll be looking at a multicellular mode with the strongest cells capable of damaging winds and hail. Equilibrium levels should be approaching 28kft which is plenty tall enough to have enough charge separation distance for lightning to generate. The wet bulb zero levels are also on the low side for June (8,000-9,000 feet) and with cool mid-level air in place, lapse rates will be sufficient to support some hail development. All this said, SPC has kept most of Delmarva and the southern third of New Jersey in a Slight risk for severe weather today, while southeastern PA and central New Jersey remains in a Marginal. It is worth noting that there will likely be a cutoff in the favorable instability and shear parameters further north, hence the highest threat lies to the south, but mesoanalysis later this morning will give a better idea of where the most favorable environment exists. The primary window for convective development will be around 11am- 5pm. In addition to the severe threat, PWATs are forecast to rise to 1.3- 1.5" with the southerly flow advecting in moisture ahead of the boundary. Don't expect any widespread hydro concerns as storm motion should be quick enough, but it is worth noting that a quick burst of heavy rain is possible for any area that remains under a convective core or any training cells. WPC has added a Marginal Risk for excessive rainfall for all of our PA zones, all of NJ, and northern Delaware. Similar to Monday, the areas to watch will be urban and poor drainage areas. Clouds and some scattered showers/a few rumbles of thunder should linger into the evening with continuing PVA as the upper trough swings through and no significant dry air building in behind the surface trough, though coverage should be limited as we lose surface forcing. With the lack of dry air advection, there could be some patchy fog developing overnight. Overnight lows will range from the mid to upper 50s, with some spots staying above the 60 degree mark. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... Saturday looks to be another showery day along with potential for some thunderstorms albeit the storms should be mainly across the northern portion of the forecast area. A cutoff low is anticipated to swing down from the north, with a series of shortwaves rounding the base of the low. Showers and a few thunderstorms look likely especially during the afternoon. With freezing levels relatively low, the main potential hazard will be small hail. Across the central and southern NJ and DelMarVA it should be a mostly cloudy day otherwise, with temperatures in the mid to upper 70s with the higher elevations of northern NJ and the southern Poconos staying in the 60s. Showers will dissipate and move out of the area Saturday night, with most of the overnight period looking dry. Skies will clear out a bit as well. Temperatures will drop into the mid to upper 50s with some spots staying at/above the 60 degree plateau. On Sunday, the region will be situated on the back side of the departing cutoff low. With another lobe of shortwave energy tracking through the region, an isolated shower or two may develop generally north of Philly however most areas should stay dry. Temperatures on Sunday will get into the low to mid 80s, with upper 70s in North Jersey and lower 70s in the southern Poconos. && .LONG TERM /MONDAY THROUGH THURSDAY/... The long term period will be characterized by diurnally driven shower and thunderstorm chances Monday and beyond with below normal temperatures for Tuesday and beyond. For the Monday-Thursday timeframe, a lot of uncertainty exists. Guidance hints at another closed low developing somewhere over the southeast US with a modified blocking pattern setting up. This would bring several shortwaves through the region bringing a prolonged period of unsettled weather with small rain chances (20-40%) each day. Important to note that the positioning of the developing low will have a large effect on our sensible weather, and both ensemble and deterministic guidance have a wide variety of solutions. While Monday looks warm with temperatures near normal due to a warm front that eventually becomes stationary, there is a decent signal for below normal temperatures for the middle and end of next week. This will be the result of strong high pressure building to our north and east and a coastal low near the North Carolina and Virginia coasts providing a stout east to northeast flow across the region. && .AVIATION /14Z FRIDAY THROUGH TUESDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas... Today...Sub-VFR restrictions likely with showers and thunderstorms, especially in the late morning/early afternoon. Some of the thunderstorms may contain gusty winds and hail. South/Southwesterly wind 5-10 knots outside of thunderstorms. Moderate confidence overall. Tonight...A wide spread among guidance remains for tonight. Showers should clear out during the mid-evening, though stratus and patchy fog is possible overnight. Restrictions look likely but confidence is low on the extent and exact timing of any MVFR/IFR conditions. Winds will generally be light and variable, before picking up late out of the northwest around 5-10 kt. Low confidence. Outlook... Friday night...A wide spread among guidance remains for Friday Night. Showers should clear out during the mid-evening, though stratus and patchy fog looks possible overnight. Have included MVFR CIGs with some spots seeing reduced visibility in fog. Low confidence. Saturday through Saturday Night...Prevailing VFR with sub-VFR possible due to scattered TSRA. Northwest winds around 10-15 kt with gusts near 20 kt. Moderate confidence. Sunday through Sunday Night...Prevailing VFR. Low chance TSRA. West/Northwest winds around 10-15 kt with gusts near 20 kt.

Rip Currents... With a medium period southeast swell and breaking wave heights around 1 to 3 feet, there is a LOW risk for rip currents at the Jersey Shore and Delaware Beaches for today and Saturday. Winds will be out of the south to southwest. && .TIDES/COASTAL FLOODING... A higher astronomical tide is anticipated the next few nights with the coming New Moon on the 18th. Friday Night's high tide has a chance to reach advisory criteria along the NJ and DE coast and within the Delaware Bay. Water levels should be lower within the Chesapeake Bay and tidal Delaware River, but some spotty minor flooding cannot be ruled out. Coastal flooding concerns will likely continue into the weekend. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None. DE...None. MD...None.
