AREA FORECAST DISCUSSION National Weather Service Wakefield VA 420 AM EDT Fri Sep 17 2021

SYNOPSIS. Coastal low pressure approaches then tracks well offshore of the local area through Friday. A ridge of high pressure builds in from the northwest late this weekend into early next week.

NEAR TERM /THROUGH TONIGHT/. As of 400 AM EDT Friday .

Overcast to mostly cloudy skies over most of the area this morning and continuing through the day on Friday. Areas of fog have developed across the Virginia Piedmont and will dissipate shortly after sunrise. Light rain showers are moving from southwest to northeast this morning as a shortwave trough tacks across the area.

A broad area of low pressure is centered southeast of Cape Hatteras this morning. The low pressure will deepen while curving NE out to sea today into Saturday. The NHC maintains a 70% chance of this disturbance developing into a Tropical Depression over the next 48 hrs. Showers, and possibly an isolated thunderstorm, on the western side of the low pressure will move in from the Atlantic Ocean during the day today. Highest rain chances will be along and east of I-95. Some areas across southeast VA may see locally heavy rain this afternoon. High temperatures will be around 80 this afternoon.

Drier conditions this evening and into tonight. Fog may develop across the area tonight (especially west of the bay) as dew points remain in the 60s to near 70s.

SHORT TERM /SATURDAY THROUGH MONDAY/. As of 400 AM EDT Friday .

The low pressure off the coast today will move farther out to sea this weekend. Isolated showers are possible Saturday afternoon across the Piedmont as a sfc high pressure builds into the area. Otherwise, mostly sunny, warm, and humid conditions for Saturday. The high pressure will become centered across New England late Sunday. This will bring a drier and cooler northeast flow to the area late Sunday afternoon into Sunday night. High temperatures will be in the mid to upper 80s with lows in the mid 60s to near 70 Saturday and Sunday. Slightly cooler low temperatures Monday morning with lows in the low to mid 60s.

LONG TERM /MONDAY NIGHT THROUGH THURSDAY/. As of 300 AM EDT Friday .

An amplified ridge aloft will be centered over the Mid-Atlantic early next week. At the same time, sfc high pressure will be center over New England and southeastern Canada, and extend south into the Carolinas. The onshore, and upslope flow inland, will likely lead to partly to mostly cloudy conditions west of I-95 Monday and Tuesday, with light showers possible. Still fairly humid conditions with dew points in the upper 60s to near 70. High temperature will be around 80 to mid 80s and lows in the 60s Monday through Wednesday.

The highly amplified ridge aloft will move over the western Atlantic Ocean and extend farther north into Canada. Both the GFS and ECMWF both show a deepening upper-level over the center of the country as the ridge moves east. The trough is forecasted to move east towards the coast mid-week. Strong cold front is expected to move across the region. Timing differs from models, but likely Thursday or Friday. Rain/storm chances increase as the front moves across. There is a chance at some below average temperatures for the end of the week. Highs in the low to mid 70s and lows in the upper 40s to mid 50s.

AVIATION /08Z FRIDAY THROUGH TUESDAY/. As of 230 AM EDT Friday .

Widespread MVFR and IFR conditions this morning as low clouds remain over the area. LIFR/IFR conditions are confined over central VA, but CIGs are expected to lower farther east as well. IFR conditions are expected towards the coast shortly before sunrise. Fog will also be confined to the VA Piedmont this morning. OVC to BKN skies expected for most of the day today. Mainly MVFR conditions. Passing showers, moving in from the Atlantic Ocean, are expected to increase during the late morning and into the afternoon. Skies may try to become scatter this evening.

Outlook . Showers/storms taper off Fri night. Some low clouds will linger Fri night into Sat morning with flight restrictions possible. Mainly dry/VFR Sat aftn through early next week, although isolated showers/storms will be possible in the SW Piedmont Sat afternoon.

MARINE. As of 340 AM EDT Friday .

Early morning analysis features a broad, rather disorganized area of sfc low pressure (~1015mb), centered just E-SE of Cape Hatteras. Meanwhile, strong ~1028 mb sfc high pressure remains over the Canadian Maritimes and northern New England, and is ridging south into the mid-Atlantic region to the west of the waters. Latest Obs and buoy reports reflect strengthening NNE flow across the local area 10-15 kt, with some higher gusts over elevated terminals in the middle and lower Bay, and farther S into the lower James River. Waves/seas continue to slowly increase as expected this morning, with 4-6 ft seas over central and southern waters, 4-5 ft over northern waters. Just south of the local area, sig seas are in the 6- 7ft range from Diamond Shoals north to Oregon Inlet, with seas subsiding a bit farther south as low pressure is tracking away from the southeast coast.

Previously referenced low will push N-NE today just offshore, slowly lifting away from the coast tonight, as sfc high pressure slowly builds in from the W-NW. The NHC still has 70% for tropical development on this system as of this morning as the system pushes away from the local area late tonight and Saturday. Given the tightening gradient, still looking for winds to slowly increase this morning, and could even briefly reach 20-25kt for the ocean S of Parramore Is. and the lower Bay. Will also see sig. seas build to 6-7 ft today into early evening, and then slowly subside to 4-5ft late tonight and into Saturday. The wind is expected to become N later tonight into Saturday morning, slowly diminishing to 10-15kt with slackening pressure gradient as the low tracks NE farther away from the coast. The sfc high then builds over the region this weekend into early next week. Sub-SCA onshore flow persists for much of the weekend into early next week, before finally turning offshore (S-SW) by the middle of next week, as sfc high pushes off the New England/Northeast coast.

As far as marine headlines go, have added a brief SCA for the middle and upper Bay, with high-res models still showing a quick surge of 15-20kt NE winds through mid to late morning. Otherwise, SCAs remain in effect for the ocean, lower Bay, lower James, and Currituck Sound through this evening, with SCAs remaining in place for the Atlantic coastal zones until early Sat evening (6pm EDT), mainly for seas lingering ~5ft.

A high threat of rip currents today, and will continue into Saturday for all beaches. A moderate risk is likely for all beaches on Sunday, as longer period E-NE swell will be slow to subside.
