530 FXUS62 KILM 310037 AFDILM Area Forecast Discussion National Weather Service Wilmington NC 837 PM EDT Sat Aug 30 2025 .SYNOPSIS... A weak cold front will drift offshore tonight with passing showers possible near the coast through the night. High pressure will build in from the north behind this front and maintain control through much of next week. A low pressure system could impact the area with enhanced rain chances around the middle of next week as it passes by just offshore. && .UPDATE... NE-ENE winds will increase to 15 to 25 mph with gusts up to 30 mph Sunday. This will result in strong north to south longshore currents along E-SE facing beaches. In addition, southerly facing beaches will observe strong east to west longshore currents. Moderate rip current risk will be in effect for all beaches, except remaining low along the south facing beaches. && .NEAR TERM /THROUGH SUNDAY/... Mid-level shortwave energy rounding the base of broader troughing over the eastern US in tandem with weak isentropic upglide, most noticeable along the 305-310K surfaces within a moist layer, have resulted in a broad area of light to moderate rain over eastern SC, which is slowly drifting east-northeastward. As this shortwave pivots through, another one is expected to be right behind it, helping to continue the rain threat across southern and eastern zones through this afternoon before tapering off this evening in NVA behind the second shortwave. A decrease in cloud cover should also be observed behind this shortwave, supporting lows in the low-mid 60s inland and mid- upper 60s closer to the coast. Surface observations indicate a stalled front is located along or near US-76 as of this writing, with ESE winds and dew points in the upper 60s south of the highway and NE winds with dew points in the upper 50s to low 60s north of the highway. This surface front will drift southward tonight into early Sunday as mid-level heights lower just slightly and surface high pressure north of the area strengthens, resulting in east to northeast winds tonight becoming a steady northeast wind across the area tomorrow. The strengthening high pressure will result in increasing northeast winds on Sunday, with breezy conditions at the beaches and over the coastal waters. The northeast flow and somewhat greater atmospheric moisture content towards the east will keep low rain chances at the coast, where isolated showers may make it to shore through Sunday. Multi-layered clouds streaming across the area and the mid-level trough axis being nearly overhead will keep high temps below-normal on Sunday, in the low 80s. && .SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/... Mid level low develops over VA early in the period while a weak low develops on the frontal boundary stalled to our north. This helps high pressure to nose in from the north, suppressing moisture further south out of the area. Blended guidance has some minor rain chances lingering along the immediate coast whereas a few operational models remain rain-free. Given the distance offshore of the low would not be surprised to see these rain chances decrease in future forecasts especially later in the period. && .LONG TERM /TUESDAY THROUGH SATURDAY/... The upper low from the short term gets kicked out by a trough coming in from the west by Wednesday, possibly touching off a few showers. This feature only then to be absorbed by an impressively large vortex dropping into the Great Lakes. This broad circulation drives a largely moisture-deprived cold front through the area on Friday. Temperatures will average about a category below climo early in the period followed by a late week prefrontal warmup to near normal. && .AVIATION /01Z SUNDAY THROUGH THURSDAY/... Despite a seemingly messy pattern currently across the area...VFR conditions should mainly be in place through the period. Rainfall somewhat surprising well inland the past few hours should become more confined to the coast and isolated in nature. A better defined NE wind field will develop and lower overall moisture in the lower levels should limit/preclude BR and or stratus development. Extended Outlook...Brief restrictions due to a passing SHRA or TSRA are possible each afternoon, especially closer to the coast. && .MARINE... Through Sunday... Light easterly winds today will start to increase this evening as a cold front settles southward. Winds will back to northeast and increase tonight through Sunday as the pressure gradient tightens further courtesy of strengthening high pressure north of the area. Speeds are expected to reach SCA criteria on Sunday morning and peak during the evening with sustained winds around 25 kts and gusts around 30 kts. Seas around 1-2 ft this afternoon rise in response to the winds, reaching 2-4 ft by late tonight and pushing into the 4-6 ft range on Sunday, peaking late in the day. The primary wave spectrum contributor will be a swell out of the northeast with a period around 7 sec while a weaker ESE swell of 1-3 ft with a period around 7 sec is also expected. Sunday night through Thursday... Period initializes with SCA as gradient is pinched between high pressure to the north and frontal boundary to the south. By Tuesday the gradient eases just enough for the six foot waves to drop down to 5 but a continued NE wind will still keep seas choppy. By the end of the period the high should finally start to break down allowing wind and seas to abate more appreciably. && .ILM WATCHES/WARNINGS/ADVISORIES...
