Area Forecast Discussion National Weather Service Wilmington NC 912 AM EST Thu Dec 5 2019

SYNOPSIS. Dry and seasonable weather will continue as high pressure moves across the area through early Fri. Warmer weather on Friday will be followed by clouds and chance of rain Friday night as a cold front moves through. Cool and dry high pressure will build down from the north on Saturday with a wedge developing by Sunday. Unsettled but warm weather will come late Sunday through early next week as a warm front lifts north followed by a cold front into mid week.

UPDATE. No significant changes to the forecast this morning with the update. I did adjust temperature trends slightly for the first couple of hours. Increased cloud cover slightly as well with some high level moisture streaming in.

NEAR TERM /THROUGH FRIDAY/. High pressure dominates today with clear skies, light winds, and near normal temperatures this afternoon in the upper 50s to lower 60s. High pressure shifts to the east tonight and winds return from the southwest, which will advect warm and increasingly moist air. The next weather making system will be a fast moving upper level shortwave trough and associated surface cold front that will bring chances for some afternoon sprinkles and light rain Friday afternoon into the evening. Highs Friday will read the low to mid 60s, which is slightly above normal for early December.

SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/. Short term begins with cold front moving through Friday night. Have slightly increase POPs for Friday night as low level moisture is most optimal in this time range. Regardless, not expecting much in the way of measurable rain with anything that forms. Lows Friday night will depend on cloud coverage. Euro clears the skies faster with lows dropping to near 40 degrees, while the GFS wants to maintain low clouds into the morning, especially along the coast. Currently favoring cooler temps for Friday night. High pressure builds in from the north Saturday keeping high temps few degrees below climo with afternoon sunshine. As the high to our north moves over the Northeast, a wedge builds into the region late Saturday. While short-lived, the wedge will keep temps cool Saturday night with low 30s inland and near 40 along the coast.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Wedge in place early Sunday will erode by Monday morning. High temps Sunday are tricky with warm advection right above the northerly flow at the surface. As the surface high over the NE moves offshore Sunday night, the aforementioned warm advection increased with the return flow. Weak isentropic lift late Sunday into Monday morning will lead to slight chance of rain, mainly along the coast. As the wedge erodes Sunday night and return flow develops at the surface, a non-diurnal temp trend develops, with temps near 50 degrees remaining pretty steady throughout the night. Rain chances and cloud cover increase during the day Monday through Tuesday with decent isentropic lift Monday and continued warm advection Tuesday. High temps both days look to reach 70 degrees, with lows Monday night near 60, which is the climatological high temp for this time of year. A cold front is progged to move through the area Tuesday afternoon/night. Behind the front, high pressure builds in from the NW cooling us down from the warm start to the week.

AVIATION /14Z THURSDAY THROUGH MONDAY/. Mostly clear skies with a few cirrus passing overhead and VFR throughout the period. Winds will be out of the northwest during the day and become calm overnight.

Extended Outlook . Mostly VFR. TEMPO MVFR conditions possible, associated with a cold front, late Fri and again Sun into Mon.

MARINE. Little concern offshore today with light northwest winds under 10 kts today shifting to the southwest Friday under 10 kts. Significant wave heights at 2 feet or less for the next 36 hours mainly from the northwest and southeast at around 6 seconds.

Cold front moves across the waters Friday night, with slight chance of rain and veering of winds from NW to NE. Tightened pressure gradient by Saturday afternoon as high builds in from the north, increasing northeast winds to near 20 kts through Sunday afternoon. Combined with increase of seas to 3-5 ft every 5-6 sec, will be close to SCA conditions. As high to our north moves offshore, return flow develops across our waters Sunday evening, with E-SE winds dropping to ~10 kts and seas decreasing to 2-4 ft every 6-7 sec. With broad high pressure over the western Atlantic Monday, a nice southerly fetch develops increasing seas to 4-6 ft every 8-9 sec Monday afternoon through Tuesday night. SCA may be need late Monday through Tuesday. S-SW winds Monday through Tuesday, increasing to 15-20 kts Tuesday afternoon. Will also see increased rain chances Monday and Tuesday. Another cold front moves through late Tuesday, with seas decreasing to 2-4 ft Wednesday with NW winds around 15 kts.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
