Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. A cold front will drop south today over the waters, leading to a few strong tstms over the inshore waters this afternoon, and radar updates are encouraged. Visibility could be reduced to less than 1 mile in heavy rain. NE winds behind the front will become gusty tonight and Sunday, easing Sunday night. As high pressure moves offshore, sw winds will resume early next week. A weak cold front late Tuesday will bring a change of wind direction but limited tstms.

Area Forecast Discussion National Weather Service Wilmington NC 739 AM EDT Sat Jun 12 2021

SYNOPSIS. Showers and thunderstorms can be expected today and tonight, as a weak cold front drops slowly southward over the area. Rain may be quite heavy at times. Cloudy and a little cooler Sunday with afternoon breaks of sunshine in wake of the weak front. A cold front with limited moisture will cross the area Tuesday, bringing a chance of showers and storms for the Cape Fear region. Temperatures near or slightly above normal and a drying trend will remain after the frontal passage.

NEAR TERM /THROUGH SUNDAY/. West to east frontal boundary across central NC will drop south across SE NC and NE SC today, serving as a focus for convection as surface heating ramps up. While there is a training of rainfall potential along the front, it's progression southward should help distribute the rainfall and lessen the flooding potential in any one spot. As such, only isolated instances of excessive rainfall are expected, and this appears to be favored over NE SC where high rain rates are apt to occur into peak heating. This potential will extend from NE SC to near Cape Fear, where repeated convective crossings could lead to briefly too much water, with 2-3 inch accumulations through tonight in spots, maxima 4".

Diurnal cooling tonight will tame convection but in vicinity of the front, continued showers are likely from NE SC interior to Cape Fear to offshore. The cooler advected air into existing high RH air Saturday night, will lead to low stratus development and patchy drizzle over portions of SE NC, upper 60s into Sunday daybreak.

SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/. Relatively quiet short term forecast period. Shortwave energy moves offshore Sunday night, allowing for rain chances to drop off inland, and only slight chances at the coast to account for any remaining lift. Through Monday, keeping a slight chance of isolated showers and thunderstorms across the area due to localized features (seabreeze near the coast and the Piedmont trough inland). A cold front starts to approach the area from the west, but lingers over Appalachia for the moment. High temperatures Monday top out around 90. Sunday night lows in the upper 60s, with Monday night lows edging up to the lower 70s.

LONG TERM /TUESDAY THROUGH FRIDAY/. Deep summertime trough quickly surges southward across the eastern CONUS Tuesday, though perhaps does not penetrate as deep as previous forecast guidance suggested. Regardless, it does provide enough dynamic support to push the cold front through the area Tuesday. This could promote some organized convection, but moisture is not as supportive as previously thought. Still, leaving in a healthy chance of showers and storms, since some decent lift will be in place. Front moves offshore late Tuesday night, leaving a drying trend through the rest of the period, as the trough pushes out the rest of the moisture. Ridging builds back in towards the beginning of next weekend.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/. Low stratus currently across the area with ceilings hovering around 1000ft, bouncing between MVFR and IFR in places. Ceilings will slowly rise through morning hours, with VFR ceilings forecasted for afternoon hours before ceilings lower again this evening behind approaching surface front. Widespread IFR ceilings expected overnight and early tomorrow morning. Convection will increase this afternoon, with a focus along the aforementioned front. Scattered to widespread thunderstorms expected to develop for late afternoon and evening, mainly across NE SC where heavy rain rates could reduce visibilities to mile or less. Outside of thunderstorms, W winds today become NW-NNE 8 knots or less late today and tonight.

Extended Outlook . IFR stratus appears likely early Sunday in wake of weak cold front, mainly through 14-15z, then improvement to VFR thereafter as drying and mixing set in. A moisture limited cold front Tuesday, will usher drying mid week.

MARINE. Through Sunday . Advisory flags were lowered as gusts have fallen below 25 kt, but winds will remain gusty at 20 kt this morning, before easing through the day, as a weak cold front drops south. TSTMs however will become a problem as they form and move over the inshore waters this afternoon, and winds will be suddenly higher near TSTMs. The rain could be heavy enough to reduce marine VSBY below 1/2NM and a few storms may become strong inshore this afternoon. Outside of TSTMs however, an easing wind trend expected. The wave spectrum will feature slowly subsiding SW waves every 6 seconds, mixed with 1-2 feet of SE Bermuda High swell in 9 second periods. Mariners are encouraged to obtain a look at radar data before venturing out, and expect TSTMs over the inshore waters this afternoon.

Monday through Wednesday . Monday brings benign marine conditions, with variable winds at 5-10kts and seas at 1-2ft at the coast with 2-3ft waves out 20nm from shore. A cold front starts to approach the area Monday night, which brings more active winds and seas. Southwesterly winds at 10-15kts will be the trend through Tuesday, with seas increasing to 2-3ft at the coast and 3-4ft out 20nm from the beaches. The front moves through the area Tuesday night into Wednesday, where a few 5ft waves could meander into the inner marine zones. After frontal passage, winds veer to the WNW, but stay at consistent speeds. Seas drop back to 1-2ft waves with 2-3ft waves featured further away from shore.
