Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles. Gusty sw winds are expected ahead of a cold front through this evening, becoming nw and N as the front moves offshore after midnight tonight. Strong high pressure will bring gusty ne winds, with large and steep seas on Wednesday. Winds will begin to let up by late Thursday, but seas are expected to remain elevated much of the period, as a gulf system impacts the waters Friday and Saturday.

SYNOPSIS. A cold front early Wednesday will bring rain, followed by cooler air through mid week. Brief clearing and drying Thursday will be followed by a wet Gulf system Friday into Saturday. Dry high pressure will build in Saturday night through Monday.

NEAR TERM /THROUGH WEDNESDAY NIGHT/. Rain showers associated with a cold front will meet the I-95 corridor between 7 and 8 pm, with measurable rain reaching the coast at or a little after midnight. A few offshore showers may briefly clip Bald Head Island at 6 pm. System totals not to go down as a memorable rain event, between 0.08-0.23" most locals, locally less, or more, is isolated locations, because of the convective nature of the pcpn. Light showers to clear the coast by 9 am Saturday. FROPA late evening well inland, with wind shifts to the W-WNW at KILM and KMYR 5z.

Cold air advection prior to sunrise will bring in cool air, but opted for upper end of guidance, based on frontal timing, clouds, wind, and a period of downslope component, min-T 50 well inland, 59-64 along the coast from Surf City to Tom Yawkee Wildlife Center.

Morning clouds likely until the front deepens late morning or early afternoon, after which unrelenting drying and mixing scours clouds in the afternoon, with bite of a north wind. Max-T Wednesday will struggle to crack 55 degrees for most areas. 15-25 kt N wind in the boundary layer Wednesday night will prevent ideal cooling, but expect a cold one, widespread 30s early Thursday.

SHORT TERM/THURSDAY THROUGH THURSDAY NIGHT/. High pressure wedge very typical of winter will bring a chilly day Thursday with highs struggling to the 50 degree mark. Thursday night will be more seasonably cool however. Not because of the warm advection however since it will not mix down to the surface, but rather as a result of increasing cloud cover.

LONG TERM/FRIDAY THROUGH TUESDAY/. Initially weak coastal trough and front later has a weakly closed low move NE. Moderate rain will overspread the area Friday that should last into Saturday morning. Cool advection behind the Saturday front will be tempered by the low amplitude flow. In fact a broad baroclinic zone spanning the Carolinas and Gulf States will serve as moisture-increasing isentropic lift surface late in the period with rain likely returning towards its end.

AVIATION /18Z TUESDAY THROUGH SUNDAY/. Scattered cirrus with a few lingering low clouds across the area as deep warm advection continues out ahead of approaching cold front. Cold front approaches tonight with light rain showers and MVFR, possibly IFR, ceilings from around 2z-12z inland and 5z-15z along the coast. May also see reductions in visibilities during this time, especially at coastal sites and within heavier rain showers. Gusty SSW winds now diminish some later in the afternoon before quickly veering to northerlies behind the front between 2z and 6z, with winds and gusts increasing early tomorrow morning.

Extended Outlook . VFR Wednesday afternoon through Thursday. Another round of MVFR is possible Friday into Saturday as an area of low pressure moves by the coastal Carolinas.

MARINE. Dangerous marine conditions to unfold in wake of a cold front, gusts 25 kt or more at or just after daybreak Wednesday. A cold front will reach the coast midnight-1am, bringing windshifts to the waters thereafter, with rain showers lingering into Wednesday morning. Marine visibility could be reduced to 2 nm or less in rain late tonight and Wednesday morning. Hazardous wind-seas, large and steep to overwhelm the waters Wednesday, dominant periods 5-7 seconds. Latest numerical wave guidance shows seas peaking 8-9 feet outer waters midday Wednesday, unfortunately remaining above 6 feet through at least Friday the 13th over the offshore waters.

The longer term of the marine forecast will be a period where conditions struggle to get below advisory thresholds. Initially this will be because of a pinched gradient on the east side of an overland wedge of high pressure Thursday. This gradient initially eases early Friday as a trough develops, the decreased wind speed offset by a more onshore flow when it comes to wave heights. Low pressure then runs up the coast Friday night into Saturday morning once again bringing stiffer winds, albeit winds that turn back offshore. It is finally on Sunday that high pressure builds in to significantly decrease wind and seas that advisories may finally drop.
