560 FXUS62 KILM 221721 AFDILM Area Forecast Discussion National Weather Service Wilmington NC 1221 PM EST Sat Nov 22 2025 .SYNOPSIS... Warm weather continues this afternoon with an isolated shower possible. A cold front will move through this evening with drier high pressure and cooler, more seasonable weather for early next week. Another frontal system will affect the area the middle of next week with much cooler weather expected by the end of the week. && .NEAR TERM /THROUGH SUNDAY/... A cold front will move through the area this evening, bringing the chance for showers to northern areas, mainly this evening. With dry air moving in at the mid levels from the west, this should prevent thunder but a rumble or two isn`t completely out of the question nearer the coast northern zones. Loss of heating should preclude convection from reaching far southern zones. Clearing is expected in the wake of the front Sunday. After highs invof 80 today, lows will fall to the low to mid 50s tonight with highs Sunday about 10 degrees cooler than today. && .SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/... Surface high pressure will build in from the north Sunday night through Monday prior to shifting off the Mid-Atlantic Coast Monday night. A weak coastal trough will likely develop along the Carolinas during this time, but moisture will remain very limited with dry Wly flow from H85 and aloft. Better low-level return flow will allow moisture to return late in the period, but more-so during Tuesday. In spite of ridging from the north cold air advection is expected to be lacking temperatures will be at or slightly above normal. && .LONG TERM /TUESDAY THROUGH SATURDAY/... H5 ridging will be far SE of the Carolinas by Tuesday as a trough exists across the Plains with most of the impulses embedded in the SWly flow aloft remaining across the western Carolinas initially. The weak coastal trough is expected to lift northward with some rainfall chances Tuesday into Wednesday morning, followed by another round of PoPs Wednesday night into Thursday associated with the passage of the next cold front. During Thursday the H5 ridge axis will shift across the eastern U.S. driving the cold front farther offshore. Cooler weather will filter into the area thanks to dry high pressure building into the region in the wake of the front during Thursday. High pressure/colder weather will likely persist through the end of the week. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... VFR conditions are expected for about the first half of the valid taf period. A little MVFR is possible should showers materialize at northern terminals. After FROPA, CIGS aob 1 kft are expected to develop and should affect most terminals. CIGS could be slow to lift after sunrise Sunday. Extended Forecast... Outside of the potential for some morning fog, expect VFR conditions through the extended period. There could be restrictions in convection with a front Wednight night into Thursday. && .MARINE... Through Sunday...SW winds of 10 to 15 KT this afternoon will become W by late afternoon or early evening before becoming N to NW at 10 KT or less overnight into Sunday. Seas will run 2 to 4 this afternoon before subsiding to 2 feet by Sunday afternoon. Sunday night through Thursday...High pressure is expected to ridge across the adjacent coastal waters from the Ohio Valley region with N-NEly winds. As the high migrates toward the east the flow will veer to an Ely direction during Monday. A weak coastal trough could delay additional veering until Tuesday as it becomes increasingly diffuse in the synoptic scale flow. A SWly fetch with increased winds will develop Wednesday ahead of the next cold front slated for passage around Thursday. Could be a shot of stronger offshore flow in the wake of this boundary late Thursday. Seas will be around 3 ft through much of the forecast period, with high frequency seas Wed. Any offshore flow late in the period would open up a larger range in seas. Could see a few showers Tue into Wed morning, then scattered showers Wed night into Thu morning until the front moves farther offshore. && .ILM WATCHES/WARNINGS/ADVISORIES... NC...None. SC...None.
