| Area Forecast Discussion National Weather Service Wilmington NC 113pm EST Sat Jan 17 2026 .WHAT HAS CHANGED... Confidence has increased that any rain/snow mix which does occur on Sunday will be reserved to areas mainly near and west of I-95 and would occur within the last few hours before precipitation ends during the afternoon. Accumulation is not expected due to ground temperature being above freezing. .KEY MESSAGES... 1) Rain will dominate the precipitation type on Sunday, although some snow could mix in across far inland areas before precipitation ends, with any accumulation highly unlikely. The freezing of standing water is likely to present a threat of slick spots on roadways across most of the forecast area over Sunday night into Monday morning due to overnight lows falling well into the 20s. 2) Wind chills could require a Cold Weather Advisory Monday and Tuesday night. KEY MESSAGE 1: Rain will dominate the precipitation type on Sunday, although some snow could mix in across far inland areas before precipitation ends, with any accumulation highly unlikely. The freezing of standing water is likely to present a threat of slick spots on roadways across most of the forecast area over Sunday night into Monday morning due to overnight lows falling well into the 20s. A weak cold front will sneak offshore tonight with southwest winds turning northwest by sunrise. Surface low pressure is expected to develop and track northeastward along the front offshore as a mid- upper trough pivots through the eastern US. Light rain will develop over far inland areas tonight and gradually shift eastward through the day on Sunday. Cloudiness and rain will result in a muted diurnal curve with temps staying in the 40s all day. As the mid- upper trough axis nears the region during Sunday afternoon, the surface low will be quickly lifting away to the northeast, with cooler and drier air filtering in behind it. The arrival of this cooler air and its timing with respect to back edge of the precipitation will determine whether any snow mixes in with rain before ending. The majority of the latest model guidance keeps this period of mixing short (e.g., <3 hours) and limited to far western and northern zones (far northern Bladen and Robeson county in NC through northwestern Marlboro and Darlington county in SC). Thus, the probability for any accumulation is very low, especially with air temps staying well-above freezing from this afternoon through the event. The bigger concern is for standing water to freeze as skies clear out and winds slacken, allowing low temps to fall well into the 20s, even near the coast. Note: The last widespread measurable snow across our area was January 21-22, 2025. Additional flurries and snow showers occurred on November 10, 2025. KEY MESSAGE 2...Wind chills could require a Cold Weather Advisory Monday and Tuesday night. KEY MESSAGE 2 DESCRIPTION...The mid and upper level pattern will continue to feature a trough over the Eastern U.S. This will keep temperatures well below normal despite otherwise quiet weather. As lows dip well into the 20s Monday and Tuesday nigheights even light winds could lead to isolated areas where the wind chill dips to 15 degrees, which is the threshold for Cold Weather Advisory. Both nigheights will feature light winds however so confidence is a bit low as to whether or not the headlines will be needed. Marine Through Sunday... Breezy southwest winds this afternoon will slacken this evening and veer to northwesterly behind a weak cold front later tonight. Northwest winds will increase tomorrow and back to westerly as low pressure tracks northeastward offshore. Speeds are expected to stay between 10-20 kts on Sunday, precluding the need for a Small Craft Advisory. Seas around 2-4 ft this afternoon will relax tonight as winds slacken, then rise back to 2-4 ft on Sunday. Wind waves will be the predominant wave group with a weak 1 ft ESE swell every 8-9 sec persisting. Sunday night through Wednesday... High pressure will build in from the west, passing by just to our north Tuesday night. Winds will remain on the light side with the exception of some post-frontal gustiness Sunday night. The progression of the high will turn NW flow to northerly. Swell energy will remain well offshore leading the shorter period wind wave as the dominant sea state.
