Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay.. A weak stationary front will remain stalled to the south of our area through the early portion of next week. High pressure to our ne will continue to slowly move offshore today while an area of low pressure passes to our nw on Sunday. A bermuda high will build east of the carolina coast into the middle of next week. A cold front will then approach the region Wednesday into Thursday, with high pressure building in it's wake on Friday.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 171313 afdphi area forecast discussion national weather service mount holly nj 913 am edt Sat aug 17 2019 Synopsis A weak stationary front will remain stalled to the south of our area through the early portion of next week. High pressure to our NE will continue to slowly move offshore today while an area of low pressure passes to our NW on Sunday. A bermuda high will build east of the carolina coast into the middle of next week. A cold front will then approach the region Wednesday into Thursday, with high pressure building in it's wake on Friday. Near term through tonight Morning clouds and fog continue to dissipate this morning, and skies should become partly to mostly sunny throughout. Otherwise, today the transition from the onshore easterly flow regime to a southerly return flow regime will occur as the bermuda high develops. In addition to the shifting low level flow, there is also a mid level short wave trough which should cross from the great lakes region into new england today. Expect most of the convective activity with this trough to be north and west of our region. However, if a qlcs develops, the southern poconos and northwest nj could be on the southern fringe of that risk area. Additionally, there could be isolated and scattered showers and storms ahead of the trough, as there could be some weak surface convergence with orographic effects. As for thunderstorm hazards, if the qlcs scenario develops, then the risk for strong winds associated with that could extend into the southern poconos and northwest nj. Otherwise, the risk is relatively low. Wind speed, and consequently wind shear, is rather weak in the boundary and mixed layer. However, with still relatively dry air above 800 mb, can't rule out some mid level dry air entrainment leading to downburst gusty winds. Temperature wise, we won't see the full effects of the southerly return flow today since it isn't expected to develop until this afternoon. Highs are expected to be in the 80s across most of the area which is near or just a few degrees higher than Friday's highs. Heat index values will likely get into the mid 90s for DELMARVA and portions of the 95 urban corridor, but should stay well below heat advisory criteria today. Short term Sunday The first round of showers and thunderstorms should dissipate as the short wave trough lifts further northeast through the evening. There could be a second round of showers and thunderstorms associated with an MCV (associated with the Saturday morning convective complex over ks mo il). However, as with the first round, it appears that if there is a second round, it will be mostly north and west of our area. Though the low level flow regime will have changed by tonight, we will have another risk for patchy fog to develop as clearing skies should allow radiational cooling leading to low dew point depressions. For most of the area, overnight temperatures will stay above 70 overnight. Long term Sunday night through Friday Synoptic overview: southwesterly-westerly flow will prevail at the mid- lvls through Wednesday as the area resides along the nw N periphery of the mid-lvl subtropical ridge. Various low- amplitude, but potentially convectively-enhanced, disturbances will clip the NW part of our forecast area Sunday-Tuesday as the overall storm track remains just to our nw. At the surface the stationary front looks to remain stalled south of the area with its attendant waves generally tracking east of the area. The bermuda high noses slightly westward toward the beginning of next week with warm and moist low-lvl southerly southwesterly flow developing in response. By Wednesday a longwave trough over canada will begin to amplify and the associated low-lvl cold front will likely pass through the area Thursday. Finally milder and drier air filters into the region Friday Saturday as high pressure builds briefly over the area. Dailies: Sunday: guidance has trended a bit cooler on Sunday and consequently generally have highs "only" toping out in the upper 80s to lower 90s with heat indices generally in the low to mid 90s. The precipitation forecast is a bit challenging as guidance indicates a (likely convectively- enhanced) shortwave moving over the NW half of our area. Lift associated with this feature combined with an unstable airmass (mlcapes generally in the 1500-2500 j kg range) should be sufficient to generate at least scattered thunderstorms. Consequently bumped pops in the Sunday afternoon time frame, and can't rule out some heavy rain and stronger storms (although shear will be lower than previous days). Do think for example the nam's 3+ inches of qpf are a bit overdone though. Monday: should see less cloud cover and lower storm chances Monday (although given persistent instability can't rule them out) with temperatures increasing a few degrees relative to Sunday. Currently have heat indices holding slightly below advisory criteria (for the urban corridor) but it will be a |
close call. Tuesday Wednesday: Tuesday will likely be about as warm Monday, with precipitation chances increasing as another low-amplitude wave approaches the area. Given pwats around 2 inches and cape values AOA 1500 j kg some strong storms and or locally heavy rainfall will be possible (although shear remains modest). Wednesday remains warm and muggy with storm chances remaining elevated as the cold front approaches. Naturally storms could be strong approaching the pattern transition, but details regarding frontal timing are still too nebulous to hypothesize on severe-potential at this time. Thursday: the front likely moves through the area on Thursday with some guidance hinting at two potential frontal passages; a weaker one passing through the area late Wednesday into early Thursday and a stronger one Thursday pm. Temperatures will be a bit cooler with instability storm chances also decreasing somewhat, especially over the north, as the airmass dries behind the front. Friday: Friday looks pleasant behind the front with highs in the upper 70s to lower 80s with dewpoints potentially falling into the 50s. Dry conditions prevail as high pressures builds in from the west. Aviation 13z Saturday through Wednesday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. This morning... Low clouds and patchy fog will continue to dissipate through 16z, with all sites returning toVFR by at least 18z. Winds may start light and variable, but should mostly be easterly and southeasterly below 10 kt through the morning. This afternoon... Isolated and scattered showers and thunderstorms are possible, primarily between 16 and 02z. The highest risk looks to be at krdg and kabe. At the other TAF sites, confidence is too low to include in the tafs at this time. Although winds should stay light (less than 10 kt), expect the direction to gradually shift from easterly to southerly through the afternoon. Tonight... Once showers and storms dissipate, expect mostlyVFR conditions. After 06z, patchy fog could develop. Where fog develops tonight could be very dependent on which areas see rain today, so haven't included a mention in the tafs at this time. Light southerly winds are expected overnight. Outlook... Sunday through Tuesday...VFR, with lower restrictions possible in scattered showers and thunderstorms. Southerly-southwesterly winds to 5 to 10 knots. Wednesday...VFR with restrictions likely in the late afternoon and evening with showers and thunderstorms developing. Southwesterly winds 5 to 10 knots, gusting to 15 knots. Marine Winds and seas should stay below small craft advisory conditions today and tonight. Patchy near shore fog is possible through mid morning this morning. Outlook... Sunday and Monday... Sub-sca conditions expected. Southerly winds 10 to 15 knots. Seas 2 to 4 feet. Tuesday... Sub-sca conditions expected. Southerly winds 10 to 15 knots and gusts to 20 knots. Seas 2 to 3 feet. Wednesday... Sub-sca conditions expected, however southwesterly winds may gust over 20 kts at times. Seas 2 to 4 feet. Rip currents... onshore flow is expected to continue for at least the first half of the day, and seas will remain near 3 feet. Therefore, the moderate risk for the formation of dangerous rip currents will continue on the nj shore and at the delaware beaches through this evening. Phi watches warnings advisories Pa... None. Nj... None. De... None. Md... None. Marine... None. Synopsis... Carr near term... Johnson mps short term... Johnson long term... Carr aviation... Carr johnson mps marine... Carr johnson |
