Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. A cold front will stall near the coast today and then move just offshore Sunday and Monday. Meanwhile, some gradual development is possible with an area of low pressure to move ne from the bahamas and florida Sunday and Monday. Mariners should Monitor the forecast closely for potential changes. A weaker pressure pattern is expected to develop over the area by midweek.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kilm 241011 afdilm area forecast discussion national weather service wilmington nc 611 am edt Sat aug 24 2019 Synopsis Unsettled weather is expected today as a front stalls over the area. The front will move just off the coast through Sunday and Monday. Meanwhile, a tropical low will track north up through the offshore waters of the southeast coast late Sunday and Monday, lifting off to the northeast through midweek. Near term through Sunday Much advertised cold front has begun to move into the ilm cwa. N winds have spread through entire area (where it hasn't decoupled) but main temp dewpoint boundary is lagging. Overall ill-defined boundary will get hung up near the coast today, and as synoptic nly flow collides with the sea breeze in a still moisture rich environment (esp closer to coast), expect numerous showers and tstms to develop. Main threat with the stalling front appears to be pockets of heavy rainfall that may lead to some nuisance flooding in prone areas, though widespread issues not anticipated. Various precip ensemble products showing roughly 20-40% chance of greater than 1" for much of our coastal area, with some lower end probabilities for >2" esp. Near the CAPE fear region. Otherwise expect considerably cooler temps today ranging from upper 70s far northern areas to mid 80s over southern tier. Convection should gradually wane and shift offshore through early Sunday morning as high pressure begins to wedge in from the north. Rain chances will increase again into the afternoon, but coverage QPF not as high compared to today, with better established ne flow between high pres and tropical low pressure beginning to lift NE from florida. Best chances near the coast in the afternoon. Will need to monitor placement of tropical system closely on Sun as inverted troughing north of the feature could enhance rainfall, but bulk of that is presently expected to be offshore. Temps continue below normal on Sunday with N NE flow and abundant cloudiness. Short term Sunday night through Monday night High pressure will run down through the carolinas from the north as tropical low tracks up through the offshore waters off of the southeast coast Sun night through Mon night. A lingering frontal boundary may also aid in convergence along or just off the coast. Gradient will tighten with stiff northeast winds developing along the coast and off shore. This will continue to feed moisture on shore and expect to see some gusty showers passing across the area, especially along the coast. Looks like best chance of heavier showers or convection will run up through the nc coast. The ECMWF continues to be the farthest off shore and strengthens the system as it reaches just over 300 miles east of the CAPE fear on Monday. GFS runs up closer to the coast, about 150 miles off the coast on Monday, but remains weaker. NHC continues to support gradual development of this low with a tropical or subtropical depression likely to form as it tracks up through the offshore waters off of the southeast coast. The chance of development is up to 90 percent. Overall, expect plenty of clouds around with best chc of pcp along the coast, but if storm is farther east and stronger, it could draw drier air in from the north. Main effects of this system should be felt across the coast and over the waters with increasing winds and rough seas and enhanced rip current activity along area beaches. Depending on how far off the coast the system moves, will determine how much rainfall it brings, but can not rule out some areas experiencing gusty shower with heavier rain. Also will see relatively cooler northerly flow keeping temps several degrees below normal during |
the day. Long term Tuesday through Friday Tropical or subtropical low will lift off to the northeast through mid week allowing for some drying, but looks like another front will make its way into the carolinas wed. This front may stall out along or near the coast as high pressure builds in behind it. The high will track across va on fri, moving off the nc va coast by Fri night. This should keep an onshore feed of moisture. This may keep unsettled weather, especially along the coast through mid to late week. Aviation 12z Saturday through Wednesday Frontal boundary seems to be draped over the CWA this morning. Winds will be light and generally out of the northeast. Time height indicates moisture will increase throughout the day, with clouds expected to be in the MVFR ifr range. Convection will increase as the CAPE slowly increases throughout the day. Coverage will be fairly widespread by mid afternoon. Showers will continue into the evening with lowering ceilings. Extended... Front will likely move just off the coast into Sunday but lingering moisture likely to lead to additional restrictions. Also watching potential tropical system moving ne just off the coast into early next week. Confidence low on related specifics at this time. Marine Changes are underway as a cold front gradually moves into the region. Winds have already gained a northerly component for most of our waters, with speeds at or below 10kts. Winds will stay fairly light through the day and trend more onshore in the afternoon with the sea breeze circulation. Seas will be around 2ft today. Good chance of showers and thunderstorms over the waters later today and tonight associated with cold front. Stronger NE winds and associated short period seas will develop Sunday as high pressure noses in from the north and tropical low pressure begins to lift NE from florida. Some potential for small craft conditions starting late Sunday but have held off advisory for now as appears to be mainly a Sunday night 4th period event at this time. High pressure will run down through the carolinas from the north as low tracks up through the offshore waters off of the southeast coast Sun night through early tues. Stiff NE winds will develop in tightened gradient flow, up to 20 to 25kts sun night into mon. This will kick seas up to 5 to 6 ft in the outer waters. Forecast is highly dependent on track and possible development of tropical or subtropical depression which NHC now shows as having a 90 percent chc of formation. Seas 4 to 5 ft sun eve should build to 5 to 6 ft Sun night into mon. Winds and seas will most likely reach SCA thresholds Sun eve into mon. This low will lift off to the northeast Mon night into tues with an off shore flow developing. Seas will diminish heading into mid week. Ilm watches warnings advisories Sc... None. Nc... None.
