AREA FORECAST DISCUSSION National Weather Service Wakefield VA 358 AM EST Thu Dec 12 2019

SYNOPSIS. High pressure builds over the area today before pushing off to the northeast by this evening and overnight. Low pressure develops along the Gulf Coast on Friday, then tracks northeast along the eastern seaboard over the upcoming weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 400 AM EST Thursday .

Early this morning, high pressure is centered just to the north of the region, allowing for mainly clear skies and cold temperatures. Low temperatures are still on track to range from the lower 20s across the west to the low/mid 30s along the coast.

The area of high pressure slowly pushes off to the northeast through the day today. It will be a chilly day today with temperatures only rising into the low to mid 40s (normal highs are in the low/mid 50s). Sunny skies to start out this morning, but stratocumulus will increase along the coast through the afternoon hours.

SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/. As of 400 AM EST Thursday .

The high pushes off the New England coast tonight. Moisture from a developing system to the SSW increases along a sfc trough in vicinity of the mountains while additional moisture is noted along a Carolina coastal trough. Dry air in the lower levels will initially keep most areas pcpn-free with the exception of some rain creeping along the immediate coastline and Maryland Eastern Shore (PoPs ~20%). Slight to chance PoPs are also in the forecast for areas mainly west of I-95 during the 09-12z timeframe Friday. 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). The chance to see a period of ZR/IP will continue across the NW until around 15z before transitioning to all rain. Only minor ice accumulations in the forecast(generally ~0.02" or less) for these areas, but a Winter Weather Advisory may still be needed due to the freezing rain potential. Will let the afternoon shift decide if an advisory is needed based on the latest model data.

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. Up to an inch of QPF is in the forecast across the west, tapering down to around a half of an inch closer to the coast. 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.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/. As of 400 PM EST Wednesday .

Low pressure will continue to move northeast away from the area Saturday, across the Hudson River Valley and into Quebec. Winds will turn northwest behind the low pressure system producing a downslope flow off of the mountains beginning Saturday night, quickly drying the area out. There will only be weak cold air advection as the low moves north, therefore temperatures will remain mild. Saturday and Sunday night temperatures will be in the mid 30s to mid 40s. High temperatures will be in the low to mid 50s on Sunday.

Another low pressure system will develop over the gulf coast states Sunday night and track east as an upper trough amplifies over the central CONUS. The GFS has the center of the low pressure tracking inland, west of the Appalachian mountains, while the Canadian and ECMWF have a low pressure track northeast into the southern Appalachian Monday night and developing a secondary low pressure system somewhere across eastern NC or eastern VA early Tuesday morning. The forecast leans towards the ECMWF and Canadian track. There will be a chance of a rain/snow mix across the northern portions of the forecast area at the onset of the precip Monday morning before a widespread area of rain moves in with the warmer air Monday night.

Temperatures will warm from south to north Monday night with lows in the mid 30s north and low 50s south. With the center of the low pressure tracking over the area, High temperatures on Tuesday will range from the upper 40s in the Piedmont and upper 50/low 60s close to the coast. Cold front will move through behind the low pressure with colder air moving in with high pressure.

AVIATION /09Z THURSDAY THROUGH MONDAY/. As of 125 AM EST Thursday .

VFR conditions across area terminals through the 06z TAF period. All terminals SKC/clear overnight through Thursday midday. Winds will be light from the N-NE, though some gusts to 10-15 kt expected at ORF overnight. Clouds increase from the E and SE Thursday afternoon into Thursday night.

OUTLOOK . The next system brings rain and degraded flight conditions Friday through Saturday, first with patchy light rain/drizzle early Friday, then with more widespread light- moderate pcpn later Fri/Sat morning. A gradual return to VFR conditions expected later Sat, with VFR conditions expected later in the weekend into early next week.

MARINE. As of 130 AM EST Thursday .

Strong sfc high pressure (~1037 mb) currently building S into the waters early this morning. Strong low level CAA is overspreading the waters and seeing gusts in the Bay to 25-30 kt. Have added the lower James River to the SCA headlines that had already been in place across the Bay/Ocean/Sound. For the rest of the river zones, issued a short fused MWW to cover ~2 hrs worth of gusts to 20-25 kt with expectation that this will be short lived. Sfc high settles over the area late this morning through the remainder of today with diminishing winds but seas will remain elevated (especially southern coastal waters) into the aftn or evening.

Sfc high pressure drifts off to the NE tonight. Low pressure develops along the Gulf Coast Fri then tracks NE to the mid- Atlantic states by Sat morning. Seas on Sat may flirt with 5 ft offshore but overall sub-SCA conditions are anticipated. A period of stronger winds and additional headlines does look late Sat/Sat night/early Sunday as the sfc low intensifies off the New England coast/Atlantic Canada with high pressure building in from the W.
