AMZ200 326 Am Edt Sat Apr 27 2024
Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles - High pressure will maintain control through midweek while shifting down the east coast. This will shift the easterly flow to southerly by Sunday.

Area Forecast Discussion National Weather Service Raleigh NC 627 AM EDT Sat Apr 27 2024

SYNOPSIS
An upper level ridge will remain over central NC through Monday.
Surface high pressure will continue ridging into central North Carolina as it slowly slides south along the mid-Atlantic coast through Sunday. The surface high will settle off the Southeast United States Sunday night and Monday.

NEAR TERM /TODAY AND TONIGHT/
As of 300 AM Saturday...

The upper level ridge will amplify as it shifts eastward over the region through this morning. The ridge will remain over central NC through tonight. At the surface, high pressure will remain SSE of Long Island today, then slowly slide southward off the mid-Atlantic coast tonight. While the high will generally ridge into central NC today, as it slides southward sely return flow will advect relatively warm, moist air into the area off the Atlantic, pooling over the Foothills and western Piedmont tonight. Some model guidance is still hinting at a period of increased isentropic lift, mainly over the northwest Piedmont through this morning, which could result in a period of low clouds developing over the Triad. As sely flow increases this afternoon, some low/mid clouds may develop over the southern Coastal Plain and drift nwwd through late aft/early eve.
Cannot rule out a stray sprinkle/shower, but chances are low so for now will keep the forecast dry. Highs today should range from around 70 degrees NE to mid/upper 70s SW. Lows tonight in the low to mid 50s expected.

SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/
As of 330 AM Saturday...

Warm(ing) and dry.

A ~319 dam 700 mb anticyclone will be directly over the Carolinas and within a highly amplified mid-level ridge that will remain over the ern US through the weekend. Associated subsidence will contribute to the strengthening and maintenance of a subsidence inversion that will cap a shallow, diurnal, and high-based stratocumulus layer on Sunday, followed by mainly clear Sunday night.

At the surface, a modified Canadian high will become situated off the coast of the Carolinas, just downstream of the aforementioned ridging aloft, with associated sswly flow directed across cntl NC.
High temperatures will consequently warm into the upr 70s-lwr 80s, but with comfortable humidity levels in the 30-40th percentile owing to the continental influence of the surface high. Low temperatures Mon morning will be in the 50s.

LONG TERM /MONDAY THROUGH FRIDAY/
As of 400 AM Saturday...

A slowly progressive, high amplitude ridge in the mid-levels will drift across and offshore the South and Middle Atlantic through early Tuesday, downstream of a convectively-amplified shortwave trough that will progress through the region late Tue-Tue night.
00Z/27th model guidance has trended toward a stronger/more-amplified trough as it moves across the srn Middle Atlantic, with 30-60 meter/12 hr 500 mb height falls, Tue night. The models depict, in the wake of that shortwave trough, a re-strengthening and retrogression of mid-level ridging across the South Atlantic Wed- Fri.

At the surface, high pressure off the coast of the Carolinas will continue to extend wwd and across the Southeast Mon and Tue, ahead of a pre-frontal/lee trough that will move across the srn Middle Atlantic Piedmont and Coastal Plain Tue afternoon-night. Another Canadian high, about 10-15 mb weaker than its unseasonably strong predecessor now centered over srn New England, will build down the Middle Atlantic coast mid-late next week. While its presence may result in somewhat cooler and near-below average surface temperatures along the immediate coast, areas inland, from the lwr OH Valley and interior srn Middle Atlantic to the Southeast, will remain warm and well above average, with daytime temperatures in cntl NC well into the 80s throughout the week.

The relative best chance of rain/convection will result Tue afternoon-evening, especially over the Piedmont where diurnal timing of the aforementioned shortwave and surface troughs will be maximized, then again Fri-Sat, as the next synoptic front/forcing approach from the northwest. No appreciable or widespread rain is expected throughout the week, however, so the combination of mainly dry, and warm temperatures will likely exacerbate what will become worsening Abnormally Dry to Moderate Drought conditions.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/
As of 625 AM Saturday...

24 hour TAF period: Still cannot completely rule a brief period of MVFR cigs at KINT and KGSO this morning. Otherwise, VFR conditions should prevail through the 24 hour TAF period. A period of cigs in the 5 to 10 kft range is expected this morn, scattering out during the aft as a cirrus shield above 25kft spreads across the area.
Ely/sely winds should be largely light (5kts or less) overnight, increasing after sunrise and becoming more sely/sly by this aft.

Outlook: There may be a period MVFR cigs tonight/Sun morn, mainly at KINT and KGSO, with cloud bases around 3500 ft elsewhere. Some medium-range guidance is hinting at some moisture in the low levels Mon and Tue mornings, but it does not appear saturated enough to result in any restrictions at this time. Otherwise, largely VFR conditions are expected through Tue. Generally dry weather is expected through Mon. The next chance for showers will be Tue aft/eve, with sub-VFR conditions possible Tue night/Wed morn at KRWI.
