SYNOPSIS. A cold front will move offshore tonight as a clipper system pushes east of New England. As low pressure remains across southeast Canada through Saturday, high pressure will begin to build in out of the Midwest. That area of high pressure will move overhead by Sunday and shift off to the southeast Sunday night into Monday. An elongated area of low pressure tracking out of the Mississippi and Ohio Valleys will affect the area late Monday through Tuesday, bringing wintry precipitation to parts of the region. High pressure then builds back into the area Tuesday night and into Wednesday.
NEAR TERM /THROUGH SATURDAY/. Snow showers associated with some upper energy, a surface front, and remnant daytime instability are waning this evening and should mostly peter out over the next couple of hours. Winds have started to lose their gustiness but will remain up around 10 to 20 mph through the night.
Otherwise, expect a fair weather period for the rest of the night and Saturday as high pressure builds in. A decent pressure gradient will result in gusty winds for Saturday when winds may gust up to 30 to near 40 mph at times. Temperatures will remain seasonably cool tonight and it will be below normal for temps on Saturday with highs only in the 20s N/W and low/mid 30s elsewhere. Wind chills will be some 10 to 15 degrees cooler than the air temps in many spots.
SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/. Fair weather expected with high pressure across the area. Mostly clear and cold Sat night with lows in the teens and low 20s most areas. Increasing clouds Sun/Sun night with temps Sun night mostly in the low/mid 20s with upper 20s for Delmarva areas.
LONG TERM /MONDAY THROUGH FRIDAY/. Overview and Changes from Prior Forecast .
A rather complex weather system remains on track to affect the region early next week. We are beginning to get a better idea of the structure of this system, but uncertainty remains in the forecast. One trend we're seeing is a slower arrival time for steady precipitation. It now appears the bulk of precipitation will fall between Monday night and Tuesday, with most of the day Monday staying dry.
From there, the main forecast challenge with this system, as it often is, will be precipitation type. No significant changes to the forecast philosophy in that regard, and there have been no strong trends in the latest cycle of model guidance. The best chance of an all or mostly snow event remains to the north, while precipitation in the far southern zones may be mostly rain. In between, many areas are likely to see a wintry mix. The synoptic evolution is one that will favor warm advection aloft as low pressure coming out of the Mississippi Valley tracks west of us. However, with that low weakening, some coastal redevelopment likely, and the system as a whole tending to get more elongated and shunted east-southeastward with time, the warm push won't be especially strong. Towards the surface, a cool but not cold air mass will be in place as Canadian high pressure remains centered well to our north-northwest. With a lot of low level dry air in place we will likely see decent wet bulbing effects as precipitation moves in, which would act as a cooling factor. Definitely a setup where varied precipitation types appear likely.
At this stage, QPF with this storm does not look all that impressive. There is some spread in the guidance, but an early consensus keeps most locations within a couple tenths on either side of 0.50 inches of liquid. That should preclude this from being a particularly noteworthy storm in terms of snowfall totals. However, travel impacts could be considerable Monday night into Tuesday, especially if a mix of snow, sleet, and freezing rain occurs in the urban corridor, which seems increasingly likely. We will likely not have initial snow and ice forecasts covering the entire event until tomorrow (Saturday) afternoon.
Daily Details .
Monday . Monday will likely begin with mostly cloudy or overcast skies, and that overcast will lower and thicken as the day goes on and our weather system approaches. As mentioned, trends are slower with the arrival of steady precipitation. It looks as though most of the daytime Monday will be dry, especially to the north. Precipitation, mainly in the form of snow or sleet, may begin to overspread from southwest to northeast late in the day. Kept PoPs highest to the southwest and trended them down to the north, even to below mentionable levels across the far north. Temperatures Monday should be cool but not especially cold, with some moderation in the air mass but extensive cloud cover keeping highs mainly in the 30s, to near 40 south.
Monday night-Tuesday . The bulk of precipitation is expected during this period. A messy setup all around, from the synoptic structure of the storm system to the actual surface weather conditions. Low pressure tracking out of the Mississippi Valley region will become highly elongated and likely separate into a weakening parent low tracking west of us and a developing secondary wave over or just south of us. This will lead to a fairly prolonged precipitation event. The precipitation will mainly be driven by warm advection, but that lift source is going to be weakening, and consequently so will the precipitation shield. So may be a case of a long duration but mainly light intensity event. Given the weakening dynamics and lack of strong warm advection, as well as a northeast as opposed to east or southeast surface flow, am skeptical about how much plain rain will become involved outside of the southernmost zones. Currently feel frozen ptypes will be favored in most areas, though that could certainly include a good deal of sleet and freezing rain in addition to snow. Considering the relatively modest expectations for QPF, have an early suspicion of an advisory level event in most of the area, but still a lot of details yet to be determined.
Tuesday night-Wednesday . Behind the weather system, strong high pressure will remain centered over southern Canada for this period. A drying trend is expected. The latest cycle of guidance does show a chance for light snow or mixed precip to continue into Tuesday night, possibly enhanced by an inverted trough. Have not bought into this idea yet, but it will be something to watch for. Dry but chilly conditions are expected for Wednesday. Lows Tuesday night should mainly be in the upper 10s and low 20s, with highs Wednesday mainly in the 30s.
Wednesday night-Friday . We continue to watch later in the week for an additional storm chance. Not surprisingly given the time range, models are not yet in agreement on the track of a potential area of low pressure, but the overall signal is fairly consistent that there will be a storm system offshore. Most signs continue to point towards this storm staying mainly south of our region, but given the typical margin for error at that range we certainly can't yet rule out some impacts. The most likely time frame for any impacts would be Wednesday night and Thursday, with southern portions of the area favored for precipitation, if there is any. Otherwise, chilly conditions are expected to continue for the late week period with strong Canadian high pressure to our north. Highs and lows running near to a few degrees below average.
AVIATION /00Z SATURDAY THROUGH WEDNESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Tonight. VFR. West to northwest wind around 10 to 15 knots. High confidence.
Saturday. VFR. Northwest winds around 10 to 20 knots with gusts up to 30s knots through the afternoon. High confidence.
Outlook .
Sat night thru Sun night . VFR conditions expected with increasing clouds later Sun and Sun night. Moderate confidence.
Monday . Mainly VFR. BKN to OVC CIGs are likely most of the day but should be mainly at or above 5000 ft. MVFR may develop by late in the day especially near and west of PHL. Winds may be light and variable during the morning, but will become light from the northeast. Moderate confidence.
Monday night-Tuesday . Sub-VFR conditions expected, with mainly IFR likely. A combination of snow, rain, and mixed precipitation is likely over the region, which will cause reductions in both CIGs and VSBYs. Winds mostly northeast at around 10 kt. Moderate confidence in overall trends, but low confidence in details.
Tuesday night . Sub-VFR may linger into the early portion of the night, with a better chance for improvement to VFR later in the night. Northeast wind becoming northerly then north-northwesterly at 5 to 10 kt. Moderate confidence.
Wednesday . VFR. North-northwest wind 5 to 10 kt. High confidence.
MARINE. Today through Saturday night . Small Craft Advisory remains in place through Friday night with a Gale Watch now in effect from 6 AM Saturday morning until 10 PM in the evening as NW winds may gust up to 35 knots. Expect wave heights over the ocean waters to increase to 3 to 5 feet today and then to 4 to 6 feet for Saturday.
Outlook .
Sunday-Sunday night . Once winds drop below 25 kt Sunday morning, winds and seas should stay below SCA criteria.
Monday . Sub-SCA conditions expected. Winds may be light and variable or light northerly in the morning, but should become northeast at around 10 kt. Seas 1 to 3 ft.
Monday night . Sub-SCA conditions are expected to start the night. Later in the night, marginal SCA conditions may begin to develop on the Atlantic coastal waters as seas approach 5 ft and northeast winds gust 20 to 25 kt. Rain or snow likely.
Tuesday-Tuesday night . On the Atlantic coastal waters, SCA conditions expected with seas 5 to 7 ft and northeast winds gusting up to 25 kt. Winds will turn more northerly overnight. For Delaware Bay, sub-SCA conditions should continue as gusts stay mainly 20 kt or less. Rain likely, with snow possible mainly for the waters of northern and central New Jersey.
PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory until 6 AM EST Saturday for ANZ430-431- 450>455. Gale Warning from 6 AM to 10 PM EST Saturday for ANZ430-431- 450>455.
