AREA FORECAST DISCUSSION National Weather Service Wakefield VA 627 PM EST Fri Nov 27 2020

SYNOPSIS. Weak low pressure continues to push away from the coast this evening. High pressure builds in from the west on Saturday and becomes centered over the region Saturday night through early Sunday. A strong storm system is expected to affect the region late Sunday night into Monday. High pressure builds back in from the southwest Tuesday and Wednesday.

NEAR TERM /THROUGH SATURDAY/. As of 615 PM EST Friday .

Only change to the near term forecast is that more patchy fog was added to the grids overnight. New hi-res guidance is hinting at dense fog over SE VA and NE NC overnight. Still believe that there will be some patchy dense fog over the southern VA piedmont as well. For the moment will keep the wording as patchy instead of areas. The rest of the forecast remains on track.

Previous discussion .

Latest analysis shows a weak cold front now sliding off the NC coast with a westerly flow aloft. All shower activity is now off the coast as well, but there is still a stubborn area of low clouds in place over NE NC and far SE VA (southside Hampton Roads). Skies are partly sunny elsewhere across the local area with temperatures in the mid to upper 60s in areas that have seen sun and in the upper 50s to lower-mid 60s where it has been more cloudy.

Satellite trends suggest skies will finally partially clear out over the next few hrs in the SE (and may even avg out mostly clear into the early evening across much of central VA). A shortwave trough is currently located over the midwest and will move ESE overnight, crossing the local area Sat morning. Thus, will tend to see some increase in cloud cover overnight and with some at least limited mixing, fog should be much less widespread compared to last night/early this morning. if there is any fog, it is most likely across south central VA and interior SE VA/interior NE NC. Low temps tonight range from near 40F across the far NW to 45-50F across the SE. The shortwave passes off the coast by late morning, and expect to see skies become mostly sunny from NW to SE as drier air moves in from the NW. Still mild with a NW wind around 10 mph and highs reaching mainly into the low to mid 60s.

SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/. As of 330 PM EST Friday..

High pressure settles over the area Sat night/Sunday. This results in clear skies and light winds Sat night, and cooler lows in the 30s (lower 40s SE coast). Sunny for the first half of Sunday, with increasing aftn clouds (especially across the SW portion of the CWA). High temps on Sunday will mostly be into the lower 60s (mainly upper 50s eastern shore).

Attention then turns to a potent system in the deep south that will interact with a strong upper trough diving S from the upper midwest Sun night. Phasing of the northern and southern stream occurs by Monday morning, with a sfc low rapidly deepening from eastern TN as of 06Z/Mon, and moving NNE along the spine of the Appalachians into Monday morning, and then across western PA or NY Mon aftn. While there are some timing and spatial differences among the models, the overall agreement between the GFS/ECMWF and their ensemble means is good. This leads to a high confidence forecast for a widespread rain event late Sun night through late Mon morning as a warm from lifts N through the CWA. Additional showers/isolated tstms generally shift E of I-95 by late morning through the aftn as a dry slot is progged to move in from the SSW. Total QPF amounts look to avg 1.00 to 2.00" (most of it prior to Mon aftn). Locally higher amounts will be possible given convective elements that become possible during the day Mon. Shear is impressive with models showing a strong LL jet (45-55 kts) moving across the area Monday morning through mid afternoon. As is often the case, instability will be limited, the greatest threat for any strong/severe tstms residing along the coast where somewhat warmer temperatures and better mixing is expected due to slightly more favorable instability parameters. Will carry slight chance tstms at some point Mon for all zones except the far NW of the CWA. In addition to the rain, expect breezy conditions with a few stronger wind gusts in some of the more robust convective cells (again especially along the coast and across the eastern shore). Clearing conditions by Monday aftn along/W of I-95 and a few hrs later near the coast as the cold front pushes further away from the coast. High temps on Monday range from the lower to mid 60s W to the lower 70s SE. Sharply colder Monday night with temperatures falling to the mid 30s W to lower 40s E.

LONG TERM /TUESDAY THROUGH FRIDAY/. As of 315 PM EST Friday .

Low pressure at the surface and aloft is progged to track northward and away from the region on Tuesday and Wednesday. Meanwhile, high pressure slowly builds in from the SW before becoming centered over the area Wednesday night/early Thu AM. Am still expecting cool/mainly dry conditions from Tue-Thu (with the exception of perhaps a shower or two across the Ern Shore on Tuesday). Temperatures will be a bit below seasonal averages, with highs on Tue and Wed in the upper 40s-around 50F and overnight lows in the mid 20s-low 30s in most areas. The surface highs slides offshore on Thursday as another upper low dives southward over the central CONUS while a ridge amplifies over the wrn third of the US. Our next chc of pcpn is likely to be very late next week or next weekend. Exact details will depend on the exact evolution of the aforementioned upper low. For now, have slight chc-chc PoPs (for rain) at the tail end of the period.

Slightly warmer temperatures are expected by the end of next week. Forecast highs on Thursday/Friday are mainly in the 50s. Forecast lows Thursday night are mainly in the 30s.

AVIATION /23Z FRIDAY THROUGH WEDNESDAY/. As of 615 PM EST Friday .

Still some IFR/MVFR ceilings over far SE VA and NE NC early this evening, mainly impacting ECG. Otherwise, VFR to start the period at the remaining terminals. Patchy dense fog is expected overnight, but shouldn't be as widespread as last night. Trended lower with ceilings and visibilities at PHF/ORF/ECG, while keeping RIC/SBY at VFR. Improving conditions after sunrise, with VFR expected at all locations from late morning through the rest of the TAF period. Winds light and variable overnight becoming N/NW 5-15 kts during the day Saturday.

OUTLOOK . Mainly VFR conditions prevail over the weekend as high pressure dominates. A potent storm system will impact the region Sun night through Mon with the potential for heavy rain and windy conditions. Flight restrictions are likely Sun night through at least midday Mon. Dry/VFR Mon night through Wed.

MARINE. As of 315 PM EST Friday .

A weak frontal boundary has pushed just to the SE of the local waters this aftn, with N winds averaging 5-10kt. Waves were 1-2ft with seas of 2-3ft. Sub-SCA marine conditions are expected to prevail through the weekend as a surface high currently over the Plains slowly builds eastward. That high is progged to become centered over the waters on Sunday AM before moving offshore by the end of the day. N to NW winds will average ~10kt tonight and 10-15kt on Sat. Winds become more northerly Sat night and briefly increase to ~15kt on the bay during the first part of the night (while remaining around 15kt on the ocean). Winds diminish to ~5kt and turn to the NE by late Sun AM as the high settles over the waters. Winds then become SE at ~10kt by Sun evening as the high moves offshore. Seas remain 2-4ft, with mainly 1-2ft waves on the bay from now-Sun evening.

Attention then turns to a deepening surface low that is progged to be centered over the Deep South Sunday evening. This strong low will quickly track over the Appalachians late Sun night through the day on Monday. The low is expected to be over upstate NY by Monday evening as its associated cold front crosses the waters from WSW to ENE. Pressure falls of 8-10mb/6hr will result in strong SE then S winds (25-35kt with gusts up to 40kt) in advance of the front late Sun night through early Mon aftn. The highest winds are expected over the northern coastal waters. Seas build to 7-12ft on Monday, with 3-6ft waves on the Ches Bay. While it is still 60-72 hours out, Gale Watches will likely be considered for at least the coastal waters in subsequent forecast packages. Winds become SW and briefly diminish to 15-20kt by late Monday evening before increasing to 20- 25kt by Tuesday morning as more robust CAA arrives behind the front. Winds remain W-SW at 15-25kt through Wed morning before slowly diminishing late Wed-Thu AM as high pressure returns. SCAs will likely be needed for a majority of the waters through at least Wed AM.
