Area Forecast Discussion National Weather Service Mount Holly NJ 119 AM EDT Sat Aug 15 2020
SYNOPSIS. A frontal boundary will remain stalled just to our south over the weekend. Multiple waves of low pressure will track south of us along this boundary through Sunday. Another cold front will approach from the west on Monday and move through by Monday night. This front may stall not far offshore. High pressure builds in for Tuesday and Wednesday, with another weak cold front potentially approaching by Thursday.
NEAR TERM /UNTIL 6 AM THIS MORNING/. No major changes to the forecast overnight so far, mainly just minor hourly adjustments. Showers have moved to our south, so a dry forecast is expected for the rest of the night, along with mostly mid-high level clouds.
Winds will become light and variable for many areas, with those who have a steady breeze mostly from the north to northeast direction, around 5 mph or less.
Cold/dry advection will allow for a pleasant night across the area, with lows generally in the 60s and dew points dropping into the 50s near/north of I-80. Winds will generally remain somewhat elevated closer to the coast overnight.
SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/. A midlevel vorticity maximum will progress from the upper Ohio Valley to the Appalachians on Saturday, which should gradually promote the development of a surface low in the lee of the Appalachians. Meanwhile, damming downstream of the vort max will continue to filter drier air from the surface high in the Canadian Maritimes into much of the eastern U.S. Upslope combined with large- scale lift immediately downstream of the vort max should permit the development of widespread precipitation to our south/southwest on Saturday. For our CWA, though, a banner day appears to be setting up, as residual descent from the departing surface high to our north- northeast will likely preclude the spread of precipitation northeastward. Instead, it is expected to be partly to mostly sunny for much of the day before upper cloudiness increases from southwest to northeast during the afternoon.
Deterministic models generally are too aggressive with the progression of precipitation into damming regimes, and expect the 12z GFS (e.g.) to be too quick to bring precipitation back into Delmarva (late afternoon to early evening). Have reduced PoPs to slight chance or lower for the entire CWA during the day, with fairly high confidence given model trends the past few cycles.
As for temperatures, statistical models are in good agreement, with highs generally in the lower to middle 80s (upper 70s in the higher terrain of the southern Poconos and northwest New Jersey). Used a consensus blend here, which exhibits good continuity with the previous forecast.
LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. Overview .
Strong western US ridging dominates much of the long term period, with troughing over the Great Lakes and Northeast. A large area of impressively high H5 heights in the West with widespread extreme heat at the surface there. By the middle to latter part of next week, we trend towards more zonal flow but the general theme of western ridge and eastern trough holds up. A strong +PNA signal is present. At the surface, a frontal boundary remains stalled to our south through Sunday, but will be kicked away by another front on Monday. High pressure then builds in out of Canada with dry, refreshing air which lasts for most of the week. By later in the week, an old boundary to the south may try to make some northward progress as an additional frontal system or two approach from the northwest.
In terms of translating this to our local weather, the big takeaway for next week is that hot weather will be totally absent from the forecast. Temperatures run near to mainly below average through the period. Not only that, but humidity disappears from the forecast as well. With both cooler and less humid conditions prevailing, the coming week looks much quieter than recent weeks in terms of rain and storm chances. The exception is for Saturday night into Sunday as another wave of low pressure develops along the slow moving frontal boundary still stalled to our south. This low will yield cool onshore flow and some rain, especially in the southern half of the region. So unfortunately not looking like a great end to the weekend. Beyond then, however, benign weather prevails as high pressure builds in.
Dailies .
Saturday night-Sunday night . The model guidance has struggled with this period due to disagreement in where an area of low pressure will form and track along a frontal boundary still stalled to our south. This follows an initial wave of low pressure which will be well to our northeast by this time, the same low being monitored by NHC for possible tropical or subtropical development. The farther north this second low tracks, the better the chances for a period of steady rain Saturday night into Sunday. With the 14.12z guidance suite, some improvement in agreement with the more northern and southern camps working towards each other a bit. I tend to favor drier and more suppressed outcomes overall with a rather strong area of high pressure pushing south into New England. May be a rather sharp gradient with areas such as Delmarva having a good chance for steady rain, while areas such as the Poconos and northern NJ may see little to no rain. The most likely time for rainfall will be later Saturday night into at least Sunday morning. By Sunday afternoon and especially evening, should trend drier. Areas of fog possible Sunday night in lingering light onshore flow.
Monday-Monday night . A weak cold front approaches Monday as low pressure tracks far to our northwest over Hudson Bay. Behind the departing low from over the weekend, Monday's air mass will be neither especially warm nor moist. Combined with frontal lift being quite weak, not expecting very robust convection ahead of the front and Monday should be a very nice day overall. A spotty afternoon or evening shower or storm is possible especially if the front comes through towards the peak heating hours, and especially to the north and west where forcing is better. But coverage looks limited.
Tuesday-Friday . Largely benign weather, and some really nice days. Little change in the air mass behind Monday's front, and with dew points coming down more and plenty of sunshine, Tuesday should see similar or slightly warmer temperatures than Monday with highs in the low to mid 80s. A similar story on Wednesday. Monday's front will clear us but stall not too far to our south. By Wednesday the tail end of it may shift north a bit, yielding an afternoon shower or storm chance mainly on Delmarva. Another weak cold front will attempt to approach from the north on Thursday, though it seems unlikely that it will make it this far south by then. But it may try to trigger a shower or storm ahead of it by Thursday afternoon mainly across the far north. In addition, the old front to the south may make a little more northward progress and produce a couple scattered storms of its own. Once again, however, expect Thursday to be another mainly dry and pleasant day, albeit slightly warmer and a bit more humid. Low confidence beyond then; we do keep the high heat away, but early indications are we may turn a bit more unsettled by next weekend.
AVIATION /05Z SATURDAY THROUGH WEDNESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Overnight . VFR conditions expected. North to northeast winds 5 knots or less, becoming light and variable for many areas. High confidence.
Saturday . VFR with increasing clouds. Winds begin the day out of the northeast 5-10 knots, then become easterly during the day with gusts around 15-20 knots from I-95 south and east, before shifting to the southeast late in the afternoon. Moderate confidence.
Outlook . Saturday night-Sunday night . Mainly VFR initially on Saturday night, then a lengthy stretch of sub-VFR conditions are likely from later Saturday night through Sunday night. Rain showers Saturday night into the day on Sunday will produce a mix of MVFR and IFR cigs and vsbys. The worse conditions will generally be found further to the south, but most of the area will be sub- VFR. For Sunday night, rain ends, but fog development is possible. Winds mainly from the northeast around 10 kt with gusts of 20 to 25 kt possible near the coast. Winds diminish Sunday night. Moderate confidence overall.
Monday-Wednesday . VFR. A couple of wind shifts through this period, but speeds mainly less than 10 kt and winds may be light and variable for much of the period. High confidence.
MARINE. A surface low will progress east well off the Mid-Atlantic coast overnight and Saturday, with northeast winds continuing on the Atlantic waters and Delaware Bay through Saturday. Speeds should generally be 10 to 20 kt, with some gusts near 25 kt, especially on Saturday afternoon. With onshore flow continuing through the period and the low slowly intensifying, expect seas to continue building to 4 to 6 feet off the New Jersey coast late tonight and off the Delaware coast by Saturday morning. A Small Craft Advisory remains in effect for these areas.
For Delaware Bay, winds are expected to remain below advisory criteria, though gusts may approach 25 kt at times, especially Saturday afternoon.
Outlook . Saturday night-Sunday night . SCA conditions are expected on the Atlantic coastal waters through this period as winds and seas build in association with offshore low pressure. Seas will run mainly 5 to 6 ft. In addition, northeast winds will gust 20 to 25 kt Saturday night into Sunday before diminishing Sunday evening and night. On Delaware Bay, wind gusts may approach 25 kt during the day on Sunday especially on the Lower Bay, but mainly sub-SCA conditions are expected.
Monday-Tuesday . SCA conditions may linger on the Atlantic coastal waters into Monday as seas slowly subside. Sub-SCA conditions will return for all waters by Monday night as seas fall to 3 to 4 ft. Northerly winds of 10 to 15 kt on Monday becoming light westerly Monday night into Tuesday.
Rip Currents . For Saturday, there is a moderate risk for the development of dangerous rip currents. Northeasterly winds will be 15-20 mph with gusts to around 25 mph. Breaking waves should be 3 to 5 feet with a medium period swell from the southeast.
For Sunday, there is a high risk for the development of dangerous rip currents. Northeasterly winds continue 15-20 mph with gusts to around 25 mph. Breaking waves building to 4 to 6 feet are anticipated with a short to medium period mainly wind wave from the east.
TIDES/COASTAL FLOODING. Onshore flow will continue through Sunday, with seas building off the Atlantic coast. Astronomical tides will be increasing into the weekend as well, with the new moon occurring early next week. These factors will combine to increase the chance for minor coastal flooding with the Saturday and Sunday afternoon/evening high tides. Spotty minor coastal flooding is possible with the afternoon and evening high tide on Saturday. Minor coastal flooding to advisory levels is then more likely with the Sunday afternoon and evening high tide, especially from Atlantic City southward including the Delaware Atlantic coast and up Delaware Bay.
PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory until 6 PM EDT Sunday for ANZ450>453. Small Craft Advisory from 8 AM this morning to 6 PM EDT Sunday for ANZ454-455.
