999 FXUS62 KILM 071018 AFDILM Area Forecast Discussion National Weather Service Wilmington NC 618 AM EDT Fri Aug 7 2026 .WHAT HAS CHANGED... No major changes to the previous forecast. Aviation discussion updated for the 12Z TAFs. && .KEY MESSAGES... 1) Low to moderate rain chances continue over the next several days. 2) Increasing heat and humidity is expected next week which could result in afternoon heat indices around 105F. && .DISCUSSION... KEY MESSAGE 1... Low to moderate rain chances continue over the next several days. We enter a more typical precipitation pattern with showers and storms primarily in the afternoon with the sea breeze under a wide field of high pressure. Dry air may lower coverage today and Saturday compared to yesterday, before moisture returns from the south Sunday. Into early next week the high will strengthen with rain chances isolated to widely scattered, most likely on the sea breeze in the afternoon and then inland in the evening. KEY MESSAGE 2... Increasing heat and humidity is expected next week which could result in afternoon heat indices around 105F. As ridging over the Atlantic builds westward in tandem with a persistent moisture plume, expect both temperatures and dew points to rise above normal. With highs reaching the mid 90s and dew points in the low-mid 70s, afternoon heat index may potentially reach 105F in some areas every day starting as early as Monday. && .AVIATION /10Z FRIDAY THROUGH TUESDAY/... VFR conditions expected through the period. Similar to yesterday...a brief period of IFR ceilings may hamper inland sites only lasting for an hour or two. Extended Forecast... Transient restrictions are possible in showers and storms mainly during the afternoon each day through the period. The moist low-level airmass will also support a greater potential for morning fog or stratus each day. && .MARINE... Sub-SCA conditions continue through at least early next week with winds averaging out of the south no higher than 10-15 kt, as Bermuda high pressure is locked in place off to the east. Low to moderate chances of showers and storms remain in place every day. Seas will average 2-4 ft, with a persistent 7-8 second SE swell being the primary contributor to the wave spectrum. && .ILM WATCHES/WARNINGS/ADVISORIES... NC...None. SC...None. MARINE...None. && $$ WHAT HAS CHANGED...MAS KEY MESSAGES...MAS DISCUSSION...MAS AVIATION...SHK MARINE...MAS
