453 FXUS62 KILM 172343 AFDILM Area Forecast Discussion National Weather Service Wilmington NC 743 PM EDT Fri Oct 17 2025 .SYNOPSIS... High pressure overhead thru Sat, will move offshore Sun, resulting in a warm up this weekend. A minimal chance of rain will come ahead of a cold front late Sun into Sun night. Dry high pressure will then return Mon thru Tue of next week. A dry cold frontal passage will occur Tue night with a cool down and dry conditions for the mid-week period as high pressure returns. && .UPDATE... Latest sat imagery indicates approaching thin cirrus, that should become thicker later tonight into early Sat as the 5H ridge axis approaches. Could occasionally observe pockets of opaque cirrus which may partially block the viewing of the Orionid Meteor Showers, which peaks Oct 20-21. FYI, the Orionid Meteor shower is actually the debris left by Hailey`s Comet. And some good news for favorable peak viewing, the New Moon will occur on the 21st at 825am edt. Tonights fcst lows remain relatively unchanged given the excellent radiation cooling conditions already applied to the hourly temps and the lows tonight. && .NEAR TERM /THROUGH SATURDAY/... Surface high pressure will build across the eastern Carolinas tonight. Winds should go calm by sunset and the only item interrupting ideal radiational cooling will be an area of cirrus associated with a shortwave moving through the middle of the ridge aloft. Lows should fall into the 40s for most areas except for a few 50s on the beaches. Pocosins and areas of peat soil across southeastern North Carolina, specifically Holly Shelter Gameland, may dip into the 30s again. The surface high should move offshore Saturday morning with winds turning south to southwest during the day. Plenty of sunshine should boost temps into the 70s, but remaining coolest along the beaches where a seabreeze should develop before noon. && .SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/... A warm up will continue Sat night into Sun with overnight lows a good 5 degrees or so warmer than previous couple of nights. This is aided by a slight moistening of the airmass in a southerly return flow between high pressure shifting farther off the Carolina coast and an approaching cold front into Sun night. Expect temps up closer to 80 on Sunday with a good deal of sunshine and a gusty southerly breeze. Dewpoint temps will be increasing about 15 to 20 degrees and looking at pcp water values, the best moisture return will come late Sun into Sun night ahead of the cold front. The best chc of any shwrs will come late Sun aftn inland and along the coast Sun night, but will be minimal chance. Cooler and drier air will begin to move in from west to east as the front moves through Sun night into early Mon. && .LONG TERM /MONDAY THROUGH FRIDAY/... A dry week ahead with temps fluctuating a bit. By Monday morning, the mid to upper trough will have pushed the cold front offshore while lifting off to the northeast leaving a somewhat flat flow aloft. Dry high pressure will shift eastward from the Mississippi Valley Mon into Tue. Overall, cool weather Mon into Mon night with temps up near 70 for highs and overnight lows dropping below 50 in most places inland of the coast. Then it will warm Tues before a dry cold front comes through Tues night knocking temps back down for midweek as high pressure moves in. By Fri, it will begin to warm again. A shortwave may approach from the west late Fri or into the weekend that may provide some clouds, but otherwise, should see plenty of sunshine through the week. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... VFR conditions will continue through the next 24 hours. Upper ridge axis sliding east, will reach the eastern Carolinas Sat aftn. Cirrus will overspread the ridge axis and across the area later tonight thru Sat with SCT occasional BKN. Majority of the cirrus will slide east of the area Sat aftn. Winds calm tonight due to a decent sfc based inversion as the center of high pressure migrates overhead. Could see a weak land breeze at the coastal terminals for several hrs after daybreak. Otherwise, winds to become SW around 8 kt by midday, except becoming S-SSW at the coastal terminals 6-9 kt. Extended Outlook...Gusts to 25 kt are possible Sunday afternoon. Aside from a low potential for brief MVFR ceilings or visibility Sunday night associated with showers ahead of a cold front, VFR should dominate. && .MARINE... Through Saturday...Breezy north winds will quickly diminish by sunset as high pressure builds across the area. The center of the high should move offshore Saturday morning with light offshore winds turning south to southwesterly and increasing to around 10 knots during the afternoon. The primary wave component tonight and Sunday should be an 11 second swell from the east- northeast averaging 2-3 feet across open waters but only 1-2 feet west of Frying Pan Shoals. Saturday night through Tuesday...High pressure off of the Cape Fear coast Sat night will shift farther out to sea through Sun as a cold front approaches from the west. Southerly return flow will veer to the SW and increase through Sun with building seas through Sun into Sun night ahead of cold front reaching Small Craft Advisory levels. Should see SW winds up to 25 kts with higher gusts Sun night and seas up to 6 ft. Winds will shift to the W-NW after midnight Sun night as cold front moves through and high pressure builds in from the west on Monday. Wind sand seas will diminish slowly through Mon but will be down to 5 to 10 kts by Mon night remaining light through Tues with seas down from 3 to 5 ft Mon aftn to 2 to 4 ft Mon night through Tues. Expect another dry cold front moving through Tues night. && .ILM WATCHES/WARNINGS/ADVISORIES... NC...Coastal Flood Advisory until 9 PM EDT this evening for NCZ107. SC...None.
