SYNOPSIS
The region will feel the influence of surface high pressure to the south through Saturday. A warm front crosses through Saturday night into Sunday while a potent cold front further approaches. Potent cold front crosses through Sunday night. High pressure begins to build in Monday and holds a firm grasp over the region into the middle of the week.
NEAR TERM /THROUGH FRIDAY/
The first accumulating snow of the season for many has ended and we now transition to more of a quiet period for the next few days before an active end to the weekend. While it will be mainly dry for the rest of today, it should remain mostly cloudy as the shortwave slowly moves out. Perhaps a few flakes may fall in the higher elevations of the Poconos and NW NJ over the next few hours, but not expecting any accumulations.
Skies clear out as the evening goes on as an upper level ridge builds in. Winds will go light and variable, though with some cloud cover for part of the evening, we won't have ideal radiational cooling conditions for the entire night. It will still be chilly though, with temperatures getting down into the low to mid 20s. Some spots, primarily within Delmarva, urban Philadelphia, and the coast, should stay at/above the 30 degree plateau.
For tomorrow, heights continue to rise as the ridge axis approaches the Mid-Atlantic. High pressure to the south will gradually slide offshore, fostering in a light southerly flow. This will result in warming and with large scale subsidence with the approaching ridge, skies will be mostly sunny. Temperatures will be in the upper 40s/low 50s, with some spots in Delmarva getting into the mid 50s.
SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/
Bottom Line...A potent cold front undergoing significant frontogenesis is forecast to impact the region Sunday afternoon into Sunday night. Winds of 25-30 mph with frequent gusts of 35-40 mph are expected; the coastal areas certainly seeing even higher than this. Widespread rainfall, heavy at times, with isolated thunder is expected across the region. Localized flooding is certain for poor drainage and perhaps urban areas, more widespread flooding may be in the cards. A prolonged period of strong onshore flow near the proximity of a new moon will lead to coastal flooding concerns.
The short term will start off Friday night with the region feeling the influence of surface high pressure to our southeast. With time, this surface high pressure will migrate more eastward ahead of an approaching developing surface low pressure system and set of fronts to our southwest. While high pressure influence will still be felt through Saturday, the low pressure and set of fronts will continue to draw near. By the time frame of Saturday night into Sunday morning, the warm front will likely swing through our region while the rather potent cold front continues to approach.
The cold front will look to cross through during Sunday night, bringing a handful of impacts to the region.
Friday night...Conditions are expected to be rather quiet with high pressure influence. Light S/SE flow (5 mph or less) to start the period will likely become light and variable, if not calm, for many areas by the second half of the period. Given the first half of the period is forecast to see mainly clear skies and light flow before more cloud cover builds in, efficient radiational cooling will look to take hold for the first half, and perhaps into the second half, of the period.
This may lead to some patchy fog development across the region.
Saturday...Quiet conditions overall are expected with the region still feeling the influence of surface high pressure. Fog from the overnight period may linger some into the morning.
Otherwise, a mostly cloudy day with continued warm air and moisture advection occurring.
Saturday night...Warm front approaches closer and begins to cross through. Continued warm air and moisture advection, light S/SSE flow for much of the period should allow for widespread fog to develop across the region. Some areas may even see fog development before midnight. Dense fog on the marine zones during the period is possible given the overall pattern.
Otherwise, PoPs start to increase across the region during the second half of the period.
Sunday morning...Warm front continues trek through the region if it hasn't done so beforehand. Increasing pressure gradient begins to be noticed. Potent cold front approaches closer to the region and begins to bring widespread precipitation and gusty winds to the region. Model guidance indicates this front will begin to experience decent frontogenesis during this time frame. With time, pressure gradient will tighten, PoPs will increase from the west.
Sunday afternoon/Sunday night...The most impactful time frame of the event. Model guidance indicates approaching potent cold front will begin to experience significant frontogenesis.
Strong pressure gradient over the region resulting in sustained winds of 25-30 mph with frequent gusts of 35-40 mph. Up to 50 mph gusts over the coastal areas are possible. Wind advisories are likely for the coastal regions. Categorical PoPs through the period with some elevated instability resulting in some slight chance to chance of thunder through the region. Only rainfall is expected, though some rain mixed with snow is possible for the Poconos for the end of the period (post-frontal). Heavy rainfall at times is expected. WPC maintains our entire region in a MARGINAL risk for excessive rainfall. It is likely poor drainage and perhaps urban flooding will be observed. More widespread flooding may be in the cards, but will refrain from mentioning more at this time due to lower forecaster confidence/lower mesoscale guidance.
Onshore flow, becoming stronger with time, will be present Saturday night through Sunday night for the coastal regions. A new moon is to occur December 12th. With such onshore flow in proximity to the new moon, coastal flooding is a growing concern for many locations.
LONG TERM /MONDAY THROUGH THURSDAY/
Strong building surface high pressure will follow behind the potent cold front crossing through Sunday night. The ensembles and deterministic model guidance support this high pressure then holding a dominate grasp over the region through the long term after continuing to build in Monday. Given the overall synoptic pattern and evolution, forecaster confidence in high pressure remaining in control for much of the long term is high.
Overall, the long term will look to be quiet with the exception of the lingering impacts we see Monday from the cold front (e.g., strong winds and some post-frontal precipitation). PoPS will continue to taper off Monday with no PoPs expected by Monday afternoon. No PoPs are included through the rest of the long term thereafter. Temperatures will run about average for the long term.
