Area Forecast Discussion National Weather Service Mount Holly NJ 734 PM EST Tue Nov 30 2021

SYNOPSIS. A weak cold front arrives late tonight and Wednesday morning, then it moves back north as a warm front Wednesday night into early Thursday. As low pressure tracks to our north, its cold front moves into our area Thursday night into Friday. Weak low pressure along the front will be in our vicinity Saturday before high pressure builds in Sunday. The next system should arrive Sunday night into Monday with high pressure returning Tuesday.

NEAR TERM /THROUGH WEDNESDAY/. The precipitation has exited the area as of late this afternoon and clouds are slowly starting to clear from south to north this evening. A modest upper-level jet will further move offshore through the overnight, taking the large- scale ascent responsible for today's precipitation with it. Mostly cloudy conditions will persist through the evening as a weak warm front slowly lifts off to our north. The trend has been slower with this front with winds taking a bit longer to transition to the southwest from the southeast, but most locations have seen this transition. This will result in slightly warmer lows tonight generally sitting just on either side of the freezing mark. Winds will be light and variable.

Slightly warmer Wednesday with weak warm air advection taking shape over the Mid-Atlantic. With dry air over the region and a weak mid-level ridge overhead, a quiet weather day is in store, but clouds will be increasing into the afternoon.

SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/. Summary . Milder air returns Thursday as a storm tracks well to our north. Some very light precipitation is expected for a time Wednesday night into early Thursday for parts of the area, then perhaps a few showers Thursday afternoon and evening with a cold front.

The continuation of strong northwesterly flow aloft will drive another clipper-type system just north of the Great Lakes Wednesday night into Thursday, then north of New England through Thursday night. A warm front will develop northward in advance of this system, with it lifting northward across our area Wednesday night and Thursday morning. Low-level warm air advection will increase some Wednesday night along with some strengthening of a low-level jet. Temperatures should hold steady or even slowly rise overnight Wednesday, although this could be delayed some for the far northern areas given the lingering low-level dry air.

While moisture is limited, enough forcing for ascent should result in some very light precipitation especially from about the I-78 corridor on northward. The highest PoPs are in the Pocono region. An examination of the model forecast soundings indicate moistening from the top down, however dry air remains closer to the surface. This should delay precipitation onset especially given the expected light rates. However, cooling of the column with time should result in some snow before some warming occurs. There could also be some ice pellets mixed in during the warming process aloft due to lingering dry air closer to the surface. As the warming occurs, the mid levels start to dry out and that may shut off the precipitation or could result in some brief drizzle or freezing drizzle (mainly the far north). There also becomes a lack of ice nucleation for a time and if precipitation is still ongoing and surface temperatures are still near or just below freezing, could result in some very light freezing rain. This potential looks to be short-lived and mostly across the Pocono region. Any snow and/or ice accumulations are expected to be very light. Farther south, perhaps a little bit of a chilly rain may occur.

For Thursday, any warm air advection induced precipitation should end early then some showers cannot be ruled out in the afternoon and evening as a cold front arrives. This front looks rather moisture starved and therefore PoPs remain rather low and mostly across the northern areas. The main warm sector should surge into at least the I-95 corridor on south and eastward allowing many places to near 60 degrees or even into the lower 60s. Northwest of the Fall Line, the more warmer air may struggle to get to the surface especially if enough evaporative cooling took place Wednesday night to set up a local cold air damming scenario.

LONG TERM /FRIDAY THROUGH TUESDAY/. Summary . Mostly quick moving systems within the active northern stream; temperatures mostly at or just below average.

Synoptic Overview . Fast moving flow associated with the northern stream near the US-Canadian border may amplify some into the East at times. The amplification will be driven by the timing and strength of the train of shortwaves. The guidance has tended to amplify some shortwaves farther out in time, then when it gets closer the shortwave ends up weaker/flatter and more progressive. At the surface, a front should be positioned to our south Friday with another one to our north. Some energy should result in a weak surface low along the southern front through Saturday, then potentially a stronger system associated with the Canadian trough looks to cruise across the Great Lakes to the Northeast later Sunday and Monday. The associated front remains to our south, however the next system is forecast to already be moving into the Great Lakes region from the Midwest Tuesday.

For Friday and Saturday . An upper-level trough in the Northeast to Mid-Atlantic regions remains, however the strongest part of it is in eastern Canada. This takes low pressure into the Canadian Maritimes Friday with the first cold front well off of our coast. A secondary cold front should be working into our northern areas during Friday, before settling southward some Friday night as weak high pressure slides by. A weak surface low may travel along the front and be in our vicinity Saturday, however precipitation chances are less certain given the weak nature of the system and also the quick motion. Temperatures Friday should rise into the lower 50s for the southeastern areas with some cooling taking place Saturday.

For Sunday through Tuesday . The fast flow aloft continues with surface high pressure sliding across our region Sunday. The forecast challenge this far our is how the incoming shortwave energy interacts or amplifies the next trough in the Plains to the Great Lakes. Some guidance phases it resulting in a deepening low near the upper Great Lakes Sunday night and Monday. Some other guidance is not as robust with this and therefore has some weaker energy ejecting out ahead it. Given the guidance has tended to be to robust so far at this time range (as it gets closer), went with the more progressive guidance for now. This results in another system cruising nearby with a cold front arriving Monday then high pressure follows into Tuesday.

AVIATION /01Z WEDNESDAY THROUGH SUNDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight . VFR with BKN-OVC CIGs around 5000 feet gradually becoming scattered and dissipating with time, though it may take much of the night (especially for areas north/west of PHL). Winds either light southwesterly or light and variable. Moderate confidence.

Wednesday . VFR with winds generally ranging from 230 to 300 degrees, primarily ranging from 5 to 10 kt. Moderate confidence.

Outlook .

Wednesday night . A period of MVFR or IFR possible with some light rain, especially north and west of PHL. A brief snow or mix possible at ABE and RDG. Light and variable winds to locally southerly near 5 knots. Low confidence.

Thursday . Lingering light rain possible early, otherwise improving to VFR. A few showers possible in the afternoon and evening. Southwesterly winds increasing to 10-15 knots, becoming west at night. Low confidence.

Friday . Mainly VFR. West-northwest winds 10-15 knots, diminishing at night. Moderate confidence.

Saturday . Some sub-VFR possible for a time, otherwise VFR. West- northwest winds 5-10 knots. Moderate confidence.

Sunday . VFR. Northerly winds around 5 knots. Moderate confidence.

MARINE. Winds gusts will increase to 25 knots tonight over the northern Atlantic zones (near and north of Atlantic City), with an SCA in effect through 7 AM Wednesday. Wind gusts generally 20 knots or less over the Delaware Bay and southern Atlantic waters tonight. Seas from 2 to 4 feet through tonight over all the waters.

Sub-advisory conditions anticipated for Wednesday with west- southwest winds from 15 to 20 knots and seas from 2 to 3 feet.

Outlook .

Wednesday night . The conditions are anticipated to be below Small Craft Advisory criteria.

Thursday and Friday . Small Craft Advisory conditions probable, diminishing later Friday.

Saturday and Sunday . The conditions should be mainly below Small Craft Advisory criteria.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory until 7 AM EST Wednesday for ANZ450>452.
