Area Forecast Discussion National Weather Service Mount Holly NJ 1206 PM EDT Sat Sep 9 2023 .SYNOPSIS... A weak front will be nearly stationary across our region today into Sunday, then it is forecast to move offshore early next week. A stronger cold front arrives later Wednesday into Thursday, with weak high pressure approaching from the west on Friday. && .NEAR TERM /THROUGH TONIGHT/... The overall weather pattern for today and tonight will vary only slightly from that of Friday. A mid level trough is forecast to extend from the Great Lakes to the southeastern states, with a mid level ridge remaining over the western North Atlantic. Short wave energy traveling in the mid level southwesterly flow is expected to aid in the development of afternoon and evening showers and thunderstorms. The location and exact timing of the initial convective development will be somewhat dependent on the position of the nearly stationary frontal boundary extending across our region, along with any remnant outflow boundaries from the showers and thunderstorms that occurred during the past 24 hours or so. The moist unstable atmosphere will allow for the development of some strong to severe thunderstorms again today with the potential for isolated damaging wind gusts. However, today's primary threat from the thunderstorms may be locally heavy rainfall. The vertical wind profile suggests the likelihood of training convective cells. As we head into this afternoon, thus far convection has been limited to just a shower or two mainly in southern Delaware. Low clouds were quite extensive this morning. Though RAP analysis suggest 2500-3500 j/kg CAPE across areas southeast of I-95. 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 more limited than yesterday. We are starting to warm 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 will likely still fire this afternoon, probably similar to yesterday along the sea breeze in south/central New Jersey and Delaware and then lift northwestward, expect the storms will not be as strong as yesterday. 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 toward Sunday morning may result in showers and isolated thunderstorms expanding across our area, particularly across eastern PA into northwest NJ late tonight, then southeastward early tomorrow morning. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... Temperatures much closer to average however it will remain humid. Some convection around each day with it more numerous during peak heating. The axis of a weakening upper-level trough is forecast to arrive during Sunday. This will keep a weak surface front draped nearly north to south across our area. Given some cooling aloft and some additional forcing for ascent with the trough aloft arriving, some increase in convective development should occur especially in the afternoon and evening hours. While there will be cooler temperatures (highs in the low to mid 80s overall), it will remain humid as precipitable water values likely remain in the range of 1.5 to 2.0 inches. However, the instability will be held down (closer to 1000- 1500 J/kg of MLCAPE) which should mostly keep the thunderstorms intensity in check especially with weaker mid level lapse rates and moist profiles. Locally very heavy rain will be probable once again with the high precipitable water values and potentially slower storm motions. Given recent areas of heavy rain, a SLIGHT risk for excessive rainfall leading to possible flash flooding has been added from roughly I-95 north and west (a MARGINAL risk a bit outward from there). Convection should begin to decrease in intensity and coverage as we go into the overnight hours Sunday night. Some showers and storms will persist through the night though, particularly for areas near and northwest of the I-95 urban corridor. Low temperatures are forecast to be mainly in the 65-70 degree range. As we go through Monday, the axis of the weak upper-level trough crosses our region. This will take a weak cold front offshore. Some lingering forcing for ascent with the weakening trough aloft will support some convective development especially in the afternoon and early evening hours. While there will be cooler temperatures it will remain humid, however the instability will be held down some again which should lower the chances for a severe thunderstorm. Locally very heavy rain will be probable again due to high precipitable water values and potentially slower storm motions. && .LONG TERM /TUESDAY THROUGH FRIDAY/... Summary...Cooler temperatures, with humid conditions ending for the second half of the week. Some showers and thunderstorms should return mainly for Wednesday with a cold front. Synoptic Overview...An initially positive-tilt upper-level trough is forecast to slide across the Midwest into the upper Great Lakes and adjacent Canada Tuesday, then as it shifts eastward its axis becomes more neutral. The trough is forecast to close off before moving into the Northeast and Mid-Atlantic regions Wednesday and Thursday. At the surface, low pressure is forecast track across the eastern Great Lakes and into New England with an associated cold front crossing our region later Wednesday into Thursday. The timing details will depend on the strength of the trough as a closed low will tend to be a little slower. While the main closed low starts to open up and lift away from our area Thursday night and Friday, a general trough aloft remains in place and this will deliver cooler temperatures. For Tuesday...There may be a lull in the convective chances for a time as a little bit of ridging is overhead well east of a positive- tilt upper-level trough in the Midwest and upper Great Lakes. There are hints at some subtle shortwaves within the southwesterly flow aloft and this could be enough to produce a few showers or thunderstorms during peak heating, therefore generally kept a slight chance PoP (20 percent) in the forecast during the daytime. The chances for showers and a few thunderstorms look to increase at night as the aforementioned upper-level trough amplifies across the Great Lakes and even starts to close off. This will drive surface low pressure into the eastern Great Lakes by early Wednesday, and increasing forcing for ascent should start to overspread our area. Cooler temperatures are forecast, however it will remain humid. For Wednesday and Thursday...This time will be dominated by an incoming strong upper-level trough/closed low. This will drive surface low pressure to our north, however its cold front is forecast to cross our area later Wednesday into Thursday. Increasing forcing for ascent occurs and showers and some thunderstorms may be ongoing Wednesday morning before potentially becoming more widespread during the day Wednesday. The extent of cloud cover and convective coverage will determine how much instability can become realized, and therefore the intensity of thunderstorms. Locally heavy rain will be quite possible given a plume of higher moisture in place combined with stronger forcing. Temperatures are forecast to be held down due to more cloud cover and showers/thunder, however it will continue to remain humid ahead of the cold front. While the timing can change especially with the idea of a closed low moving in, the cold front currently should be shifting to our east to start Thursday. Cyclonic flow and cold air advection in its wake will result in cooler temperatures and dew points dropping. While the deep moisture plume is offshore, cannot rule out some instability showers/thunder especially across the northern and western areas. Even cooler and drier air should then settle in for Thursday night. For Friday...As the closed low opens up and shifts farther to our north, a trailing trough axis is forecast to be over our region. This will continue to result in cooler temperatures and lower dew points. Despite the trough axis aloft and some shortwave energy associated with it, plenty of drying should preclude any showers from occuring. We continue to monitor the track forecast for Hurricane Lee. While the hurricane is 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 /16Z SATURDAY THROUGH WEDNESDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Early this morning...Variable conditions, with some TAF sites experiencing MVFR or IFR ceilings and visibilities. Variable wind 5 knots or less. Medium confidence. Today...Mainly VFR. Scattered showers and thunderstorms developing this afternoon. The thunderstorms will bring locally heavy rainfall along with MVFR/IFR conditions. Wind favoring the southeast to south 8 knots or less. Medium to high confidence. Tonight...Variable conditions with scattered showers and thunderstorms. Low clouds and patchy fog developing overnight. Variable wind 5 knots or less. Medium confidence. Outlook... Sunday and Monday...VFR, although times of sub-VFR conditions probable along some showers and thunderstorms. Southerly winds 5-10 knots diminishing some Sunday night, then becoming west to northwest Monday and Monday night. Low confidence. Tuesday...Mainly VFR. However there is a small chance for a few showers during the day, followed by some increasing chances at night when sub-VFR conditions may occur more. Northerly winds 5-10 knots becoming southerly in the afternoon. Low confidence. Wednesday...Sub-VFR conditions possible with showers and thunderstorms. Southerly winds around 10 knots, becoming west to northwest at night. Low confidence. && .MARINE... A southerly wind 10 to 15 knots today is forecast to decrease to 5 to 10 knots tonight. Waves on our ocean waters are expected to be around 2 feet, with waves on Delaware Bay at 2 feet or less. Outlook... Sunday and Monday...The conditions are anticipated to be below Small Craft Advisory criteria. Some thunderstorms are possible, although the greatest chances/coverage should stay inland from the waters. Tuesday...The conditions should remain below Small Craft Advisory criteria, although seas within the ocean zones may begin to approach 5 feet at night. Wednesday...Small Craft Advisory conditions possible as seas within the ocean zones may build to around 5 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.
