Area Forecast Discussion National Weather Service Newport/Morehead City NC 616 PM EST Tue Dec 7 2021

SYNOPSIS. Low pressure with plentiful moisture will move northeast and impact the region late tonight and Wednesday. High pressure will build back over the area Thursday into Friday. A complex frontal system will affect eastern North Carolina over the weekend.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. As of 615 PM Tuesday . Reduced or removed pops thru evening with main batch of rain developing late as isent lift rapidly increases ahead of approaching short wave and developing sfc low.

Prev disc . The cold front now stalled ~150mi SE of Cape Lookout with weak high pressure at the SFC centered just SE of the Great Lakes moves east toward the Mid- Atlantic coast tonight. N- NEerly winds have calmed down as high pressure filters in behind the CAA surge behind the front. Mid level trough across the central US will swing towards the SE CONUS tonight. Coastal low will begin to form along the stalled boundary offshore as a result. A few scattered showers have developed offshore and will begin to spread along the immediate coast in the evening and gradually spread inland tonight into the overnight hours as the coastal low begins to become more organized. Total QPF across most areas will likely be less than a tenth of an inch overnight. Steady NE wind on the north side of the low will allow temps to drop down to the upper 30s to low 40s inland with mid 40s along the coast.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/. As of 400 PM Tuesday . Much needed widespread rainfall will occur Wednesday as low pressure develops and moves northeast along the stalled front just off the coast. Moist airmass around the low with PWats climbing to AoA 1.25in allow for periods of moderate rain during the day. Forecast rainfall amounts of .5 inland to an inch along the coast will be possible through Wed evening which should help ease at least temporarily the dangerous fire weather conditions which persist across eastern NC. Precip tapers off in the afternoon and evening as the low slides the NE. Overcast skies and precip keep highs in the mid- upper 40s inland, low- mid 50s coast.

LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/. As of 3 PM Tuesday . High pressure builds into the area Thu into Fri with mostly dry conditions. A warm front will lift north through the area late Fri into Fri night and could touch off some patchy very light rain, though most locations should remain dry and any rainfall that occurs with this system should be very light. Highs Thu will be in the 50s, warming into the 60s Fri.

The forecast for the weekend has significant uncertainty, especially Sunday as another strong cold front is forecast to move across the area. Sat will have the potential to be very warm as deep moderate southerly flow develops over the area in the wake of the warm front. Complicating the forecast Sat will be the potential for shower activity to advect off the Gulfstream into coastal sections along with the chance for coastal sea fog as warm/moist air moves across the now cool shelf waters. Areas inland should be able to warm into 70s

Guidance has come into better agreement that the cold front will be progressive, racing across the area during the first half of the day Sunday, with much cooler air filling in behind it. Dry and cool pattern to start next week.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. SHORT TERM /through Wednesday/ . As of 615 PM Tuesday . Expect a mix of VFR and MVFR thru late tonight with cont mainly dry conditions. Rain will rapidly develop/overspread region late tonight thru Wed morn with cigs quickly lowering to IFR with some reductions in vsbys expected as well. IFR will then persist thru mid to late aftn then as rain begins to shift E will see cigs grad improve from W to E With VFR expected late well inland.

LONG TERM /Wednesday night through Saturday/ . As of 3 PM Tuesday . VFR prevails Thursday. Patchy light rain and occasional sub VFR conditions will be possible late Fri into Sat as a warm front lifts north through the area. Scattered rainfall Saturday night could bring vis and ceiling restrictions into Sunday with gusty winds ahead of a cold front, which will cross the area Sunday

MARINE. SHORT TERM /through Wednesday/ . As of 615 PM Tuesday . No signif changes with pres grdnt grad loosening tonight with NE winds diminishing. Seas shld grad subside with SCA ending for the cstl wtrs.

Prev disc . SW- NE oriented cold front located about ~150mi SW of Cape Lookout. Nerly winds 15 to 20 kt gusting to 25 to 30 kt for coastal waters in the last bit of the CAA surge behind the front. Coastal water winds lay down this evening as high pressure takes hold. 5 to 7 ft seas subside through the near term, falling below 6 ft tonight. Coastal low begins to develop along the stalled frontal boundary tonight veering winds to become more NEerly 10 to 15 kt. Southern waters could see a few showers this evening into the nighttime hours as the low becomes better organized and begins moving NE. Wednesday, winds back to become Werly 15 to 20 kt briefly around the counterclockwise flow of the low. The low pressure center will be closest to coastal waters, ~30-50mi offshore of Cape Lookout, late Wed AM, and continuing its NEward path offshore through the evening hours. Overnight Wed NWerly winds 15 to 20 kts gusting to 25kts creates a brief window of marginal SCA conditions. Short fetch winds don't allow nearshore seas to build significantly but choppy conditions are expected in short period waves with 6 to 7 footers possible 20-30mi offshore. Later updates will consider the possibility of SCA product issuance once the current SCAs drop.

LONG TERM /Wednesday through Saturday/ . As of 3 PM Tuesday . Light winds emerge later Thursday into Thursday night as high pressure moves overhead and offshore. Moderate SW winds develop Friday as the high slides further offshore, becoming gusty Saturday as a cold front approaches from the west. SCAs likely needed Saturday, with Gales possible. The front will cross the waters quickly Sunday, will NW winds developing behind it.

Seas increase with increasing winds Friday night into Saturday, with hazardous winds arriving Saturday and likely continuing into early next week.
