AREA FORECAST DISCUSSION National Weather Service Wakefield VA 421 PM EST Thu Dec 12 2019

SYNOPSIS. High pressure exits to the northeast through tonight. Low pressure develops along the Gulf Coast on Friday, then tracks northeast along the eastern seaboard over the upcoming weekend.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. As of 330 PM EST Thursday .

Sfc high pressure will be slowly exiting to the northeast through this evening, before pushing off the England coast late tonight. ENE flow off the ocean has already brought a batch of stratocumulus into SE VA and coastal NE NC this afternoon where overcast conditions are expected to continue into tonight. Elsewhere, a mostly clear sky through this evening will give way to increasing clouds before midnight and generally overcast conditions all areas prior sunrise.

Moisture from a developing system to the SSW increases along a sfc trough in vicinity of the mountains tonight. There could be a bit of light rain that funnels north along the immediate coast prior to 12z. Otherwise, the focus of attention in the short term forecast will be on whether or not parts of the Piedmont see any frozen pcpn arriving early Friday morning. At this time, have slight chc Pops (~20%) limited to the coast from 06z- 12z. Also have slight chc PoPs across the far western extent of the FA from 06-09z, increasing to 30-50% by 12z.

Thermal profiles continue to indicate the potential for this precipitation to begin as a period of ZR (IP across the NW where there will be colder temperatures aloft initially). The chance to see a period of ZR/IP will continue across the NW until around 14z before transitioning to all rain. Only minor ice accumulations (if any) are forecast (generally ~0.02" or less) for these areas, and thus have opted not to have a winter wx advisory as impacts will be very minor to none and very short- lived. Will mention light ZR/IP potential in the HWO.

Lows for tonight will occur this evening or before midnight, then steady or slowly rising temps through 12z. Lows from upr 20s/nr 30 NW to around 40 SE.

SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/. As of 330 AM EST Thursday .

WAA moisture will continue to overspread the area from the SSW through the day on Friday, staying as plain rain for all areas minus the aforementioned far NW/W locations. Deepest moisture arrives later in afternoon Friday into the overnight hours with likely to def PoPs in the forecast for this timeframe. Temperatures will vary widely from NW to SE during the day on Friday due to the in-situ wedge setup with highs ranging from around 40 across the NW to near 60 across the northern OBX.

Low pressure lifts NE and away from the mid-Atlantic region on Saturday. However, upper level energy rotating in from WNW will generate additional rain chances, especially through the morning. PoPs continue to trend lower in the afternoon with potential dry slot arrival. Highs from the low 50s NW to the low 60s SE. Total QPF through Saturday will average around 1".

Dry wx returns Saturday night into Sunday with WNW flow developing. Fair to partly cloudy Saturday night, then mostly sunny on Sunday. Lows Saturday night in the upr 30s to mid 40s. Highs Sunday in the 50s.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. As of 400 PM EST Thursday .

An upper trough will be across the central US early next week with a sfc low pressure developing across the southern Plains Sunday night into Monday. At the same time, a broad area of sfc high pressure will stretch from Ontario to the western Atlantic. A frontal boundary will develop and extend from the center of the sfc low (located over the southern Plains) to the Mid- Atlantic. This will produce a chance of rain showers Monday. There will be chance of rain and snow mix Monday morning north of Richmond and for the Maryland Eastern Shore with temperatures in the low 30s, before changing over to rain by Monday afternoon. Rest of the area, low temperatures will be in the upper 30s to near 40 Monday morning. High temperatures on Monday will range from near 60 across northeast NC to low 40s across central VA.

It will turn dry once again Monday afternoon into Monday night. An area of wide spread rain will likely move into the area a the center of the sfc low moves across. Similar to yesterday, the GFS keeps the center of the low well north and west of the area, while the Canadian and ECMWF track the center of the low across VA (which is slightly farther north than models runs showed yesterday). With a track slightly farther north, temperatures will warmer. The warmer air will likely move into the area beginning Monday night with a southerly flow. High temperatures Tuesday will reach the upper 60s across the northeast NC and Hampton Roads, upper 50s to near 60s across Delmarva, and low to mid 50s along and west of I-95.

Rain will move offshore Tuesday night with the passage of a cold front. Sfc high pressure, that was located of NW Canada, will move into the area behind the front bring colder temperatures. High pressure will remain over the area for Tuesday and Wednesday with dry conditions. High temperatures will be in the upper 30s to mid 40 with low temperatures in the low/mid 20s to low 30s at the coast.

AVIATION /22Z THURSDAY THROUGH TUESDAY/. As of 1230 PM EST Thursday .

Stratocu moving in off the ocean will allow for borderline MVFR CIGS at the southeast terminals this afternoon into tonight. Otw, clouds increase from SE to NW late this afternoon into this evening. Ceilings are then expected to lower to low end MVFR or IFR early Friday morning (starting 10-12z), especially for KRIC/KSBY as the next system approaches the region. Pcpn mostly in the form of rain will then overspread the entire region from SW to NE during Friday. Winds generally remain light (5-10 knots) from the N to NE through the forecast period.

OUTLOOK . The next system brings rain and degraded flight conditions Friday afternoon through Saturday. The heaviest/steadiest rain is expected Friday night through Saturday morning. A gradual return to VFR conditions expected later Sat, with VFR conditions expected Sunday into early next week.

MARINE. As of 400 PM EST Thursday .

High pressure weakens and moves offshore this evening. SCA now up for North Carolina waters will come down this evening as seas subside. Winds currently around 10 kt in the bay and 10 to 15 kt in coastal waters will remain near constant or decrease slightly by a couple of knots this evening. Waves will remain generally 1 to 2 ft in the bay with seas of 3 to 4 ft in coastal waters this evening into the day Friday. Low pressure will move into the region Friday into Saturday bringing with it increased waves of 2 to 3 ft in the bay and seas of 4 to 6 feet beginning Saturday before subsiding during the day on Sunday. Winds will weaken to 5 to 10 kt on Friday before increasing to 10 to 15 kt Saturday morning and 15 to 20 kt (with coastal waters sustained at 20 to 25 kts) Saturday evening into Sunday morning. SCA will be possible mainly for winds (possibly for seas) in later updates but will not be issued at this time.

A weak cold front settles S over the waters Sun night shifting winds from SW to NE (though conditions expected to be sub-SCA). Onshore winds Mon become SSW (and potentially increase to at least low end SCA) late Mon into Tue as that front lifts back N as a warm front. A stronger cold front is forecast to cross the waters late Tue.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
