116 FXUS62 KILM 161024 AFDILM Area Forecast Discussion National Weather Service Wilmington NC 624 AM EDT Thu Oct 16 2025 .SYNOPSIS... High pressure building in from the northwest will usher in the coolest air since Spring through the end of the work week. The high will shift offshore ahead of a front over the weekend bringing a gradual warm-up and low rain chances. More high pressure will bring cooler, drier weather back for early next week. && .UPDATE... Updated aviation discussion for 12Z TAFs. && .NEAR TERM /THROUGH TONIGHT/... Key Messages/Highlights: *Rain Chances: none *Temps: below normal Confidence: *High Details: Low to mid-level high pressure will build from the northwest through tonight as a cutoff mid-level low moves SE over the NW Atlantic. Some low-level cold advection will result in an unseasonably chilly air mass keeping temperatures below normal. Highs should generally be in the lower 70s with lows tonight generally in the mid 40s, except a bit milder along the coast and a bit colder inland in some of the typically colder spots due to decent radiational cooling conditions. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... High pressure will be in control through the short term period. We`ll experience slight warming from Friday into Saturday as the ridge aloft starts to shift offshore, allowing a slow recovery of warmer, moist air. Nothing in the way of forcing will impact us during the period so we`ll remain dry with light winds under the center of the high. Highs will warm from near 70 to the mid 70s Friday to Saturday, with low similarly going from the 40s to the 50s. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... A cold front will be approaching the area Sunday with surface high pressure slipping offshore. A surge of modest moisture looks to push in or just north of the area Sunday night supporting low POPs with no thunder expected. The trough aloft will be decently amplified with a +30kt jet embedded in it at 925mb. There`s some uncertainty about where this jet will end up, but if it shifts a bit closer to us the forecast for late Sunday into Monday could end up windier than it currently is, gusts near 30mph possible. Otherwise, high pressure will build in afterwards with dry, cooler weather returning. && .AVIATION /09Z THURSDAY THROUGH MONDAY/... High confidence in VFR conditions thru 12Z/17 as high pressure builds into the area bringing more low-level dry air with it. Thus, no concern for low clouds/fog. Breezy northerly winds will be a bit gusty during the daytime, especially during the afternoon. Extended Outlook...Mainly VFR. Very low risk for restrictions Sun night as a cold front passes through with some showers. && .MARINE... Through Tonight...High confidence this period. High pressure will build in from the NW pushing a colder/drier air mass over the relatively warm Atlantic waters. This will lead to an enhanced pressure gradient and breezy northerly winds close to Small Craft Advisory levels at times. Significant wave heights could also reach close to Advisory levels (6 ft) near the Gulf Stream but not thinking probability/coverage is sufficient for raising a headline at this time. Friday through Tuesday...High pressure moving overhead will lead to improving marine conditions with winds and seas decreasing through the day Friday. The high will shift offshore Saturday with winds becoming southerly ahead of a cold front. SCA conditions may be possible late Sunday into Monday with the frontal passage. High pressure will build in again for early next week with a return to better conditions. && .TIDES/COASTAL FLOODING... Minor coastal flooding is likely into early next week as we approach a full moon, particularly along the SE NC coast as well as the Lower Cape Fear River which includes Downtown Wilmington. && .ILM WATCHES/WARNINGS/ADVISORIES... NC...Coastal Flood Advisory until 8 AM EDT this morning for NCZ107. SC...None. MARINE...None. && $$ SYNOPSIS...ILM UPDATE...RJB NEAR TERM...RJB SHORT TERM...LEW LONG TERM...LEW AVIATION...RJB MARINE...RJB/LEW TIDES/COASTAL FLOODING...
