Area Forecast Discussion National Weather Service Wilmington NC 754pm EDT Monday May 12 2025 Synopsis The weather will remain quite unsettled as a slow moving upper low lifts from the Gulf States into the Ohio Valley through Wednesday. Very warm and largely rain-free weather is slated for the remainder of the week. Small rain chances return this weekend ahead of a weak cold front. Widespread light rain continues over most of the CWA, with pockets of heavier rain in parts of SE NC. Rain coverage and intensity will pick up again from the south later this evening Cape Fear region and northern Pee Dee region picked up 1-2" of much needed rain over the last 24 hours. Near Term - Through Tuesday Deep, moist southerly flow east of the stacked mid-upper low pressure system over the Gulf states maintains widespread showers and isolated thunderstorms through this evening and into overnight hours via decent isentropic lift. PWATs (Precipitable Waters) are near 2" across coastal NE SC per latest Storm Prediction Center mesoanalysis, and are expected to remain near the climatological 90th percentile through dawn Tuesday. Another 0.75-1.25" of rain is forecasted through early Tuesday morning, with isolated higher amounts possible. Clouds, rain, and wind will keep low temps warm tonight in the upper 60s. The stacked low over the Gulf states will start slowly lifting north tonight, moving further north into the Ohio Vally Tuesday while opening up. Mid- and upper-level dry air will move in from west to east Tuesday morning through midday, which will reduce rain coverage for Tuesday. Cooler and slightly drier air aloft will lead to increased instability for Tuesday afternoon, and scattered thunderstorms are expected, aided by PVA around lifting upper low to the WNW. Deep layer shear remains slightly elevated due to proximity of upper low, and isolated strong wind gusts will be possible. High temps Tuesday will be in the low 80s across NE SC and upper 70s SE NC where clouds may linger a bit longer earlier in the day. Short Term - Tuesday Night Through Wednesday Night The current Gulf upper low will have moved into the OH valley by the start of the period. This shoves the deepest moisture well of the area but one last healthy shortwave is forecast to rotate through the area on Wednesday, keeping POPs elevated (near categorical in some places) even as the threat for heavy rain will be over. Daytime highs close to normal whereas cloud cover will keep lows about a category above climo. Long Term - Thursday Through Monday A considerable change heading into Thursday as any lingering troughiness and PVA will be off the coast and ridging will be able to build in from the west. Thunderstorm coverage should taper to isolated at most and the afternoon will warm into the upper 80s away from the beaches. Ridging peaks Friday and and low 90s expected away from the water. A cutoff drops out of Canada and into the NE U.S. over the weekend for a frontal passage that looks to occur Sunday. Models don't seem overly enthusiastic about rain chances with the front. Given the lack of good moisture flux ahead of its arrival minimal POPs appear warranted. Marine Through Tuesday...Small Craft Advisory remains in effect for all local coastal waters through Tuesday evening (0z Wednesday) due to seas around 6 ft from SE swell. Winds remain generally out of the south tonight and Tuesday around 15-20 kts, with gusts to 25 kts this evening and overnight. Scattered thunderstorms expected over the waters this evening and through tonight, with coverage diminishing from west to east Tuesday morning. Convection coverage will be focused over inland areas Tuesday afternoon, but can't rule out an isolated storm or two over the waters. Tuesday night through Saturday...Advisory should be ending close to the start of the period as SE swell energy gets pushed a bit out to sea. Not many changes thereafter as winds settle into the 10-15kt range and the SE swell/SW wind wave combination slowly transitions to the dominant wave forecast from 3-4ft to 2-3 ft. Tides / Coastal Flooding Other - Rip Currents There is a high risk of rip currents for all area beaches on Tuesday with rough surf in 7-8 ft SE waves. Thereafter, expect a moderate risk of rip currents for at least Wednesday and Thursday. NOAA Wilmington NC Office: Watches - Warnings - Advisories NC...High Risk for Rip Currents from 6am EDT Tuesday through Tuesday evening for NCZ106-108-110. SC...High Risk for Rip Currents from 6am EDT Tuesday through Tuesday evening for SCZ054-056. Marine Small Craft Advisory until 8pm EDT Tuesday for AMZ250-252. Small Craft Advisory until 8pm EDT Tuesday for AMZ254-256. |
