| Area Forecast Discussion National Weather Service Wilmington NC 117pm EST Tuesday Nov 11 2025 Synopsis A gradual warming trend kicks in by Wednesday, with winds decreasing Wednesday night as another dry cold front moves through the area. Temperatures continue to increase everyday, becoming above normal by late in the weekend. Near Term - Through Wednesday The axis of the sharp mid-upper trough which brought a brief shot of winter weather is quickly pivoting away well offshore of the Carolinas, with rapidly rising heigheights in its wake. Nevertheless, strong cold advection and subsidence atop the boundary layer are both acting to keep temperatures and dewpoints well-below normal with highs this afternoon only expected to top out in the mid-upper 40s amidst gusty west to WNW winds and dewpoints mainly in the teens. As high pressure over the northern Gulf Coast shifts eastward and low pressure over southeastern Quebec lifts northward, the pressure gradient is expected to slacken considerably this evening, permitting a period of relatively light or even calm winds in some areas. With dew points so low and clear skies in place, expect temperatures to crash this evening and hit their lows potentially between 03-07Z before winds pick up again during the latter half of the night, causing temps to rebound a little before either going steady or slowly rising thereafter. Surface low pressure tracking to the north of Lake Superior and its attendant cold front will be the culprit for this increase in winds, and will also help to back the flow to southwesterly. Overnight lows are forecast to dip to around freezing once again, except along the coast. Enhanced southwesterly low-level flow overspreads the region from northwest to southeast during the latter half of the night, causing winds to pick up out of the southwest before dawn. Once the sun rises and vertical mixing begins, tapping into this flow will result in gusts developing fairly quickly, with speeds up to around 25kts or so at the highest. Winds will gradually wane during the afternoon, but gustiness should continue through most of the daylight hours. Although broad troughing will remain over the eastern US, southwest low-level flow and weakening high pressure over the northern Gulf will allow temps to rebound into the low 60s beneath sunny skies. Short Term - Wednesday Night Through Thursday Night A gusty start to an otherwise quiet midweek period. Gusty southwest winds ahead of dry cold front will diminish quickly into Wednesday night as they veer around as a dry cold front moves across the eastern Carolinas. The very modest moisture return will not be too noticeable and certainly will not be enough to generate any pcp. It will help to maintain slightly higher overnight lows Wednesday night and give a kickstart to a warmer day on Thursday, but expect an overall dry and sunny period with light NW to N winds. Temps should drop below 40 inland of the coast both Wednesday night and Thurs night with better radiational cooling Thurs night, allowing traditionally cooler spots to drop a bit further. With a warmer start to the day on Thurs, temps will rebound to the mid 60s most places, in mid November sunshine. Long Term - Friday Through Tuesday High pressure over the Carolinas will get suppressed a bit farther south through the weekend as the northern stream remains quite active and more progressive. A ridge up the central CONUS will maintain a NW flow over the region allowing a couple of shortwaves to move through. A weak front should drop into the Carolinas form the north, but does not look like it will make it this far south. Overall, should produce some clouds around at times, but basically, expect a dry weekend. As the center of the high shifts south and east, a W to SW return flow in the low levels, gradual height rises in the mid levels and plenty of sunshine during the afternoons will produce warming into through the weekend. Temps in the mid 60s on Friday will reach well into the 70s by Sun. Lighter winds initially should produce better radiationly cooling, but as the airmass modifies, overnight lows will rise from the 40s to 50s. By Sunday night, another moisture starved front passes through with decent SW flow ahead of it producing warmer gusty winds for Sunday. Does not look like it will tap into much cool air behind it and therefore expect continued above normal temps into early next week. Marine Through Wednesday...High pressure over the northern Gulf Coast will result in continued offshore flow with speeds decreasing through the first half of tonight as the pressure gradient weakens. However, speeds will pick up again after midnight and the direction will back to WSW well ahead of a cold front crossing the Midwest. SCA (Small Craft Advisory) conditions are expected to return on Wednesday morning mainly driven by gusts of 25-30 kts, although some 6 ft seas are likely, mainly in the waters southeast of Cape Fear. Wednesday night through Sunday...Gusty SW winds and SCA (Small Craft Advisory) conditions will start the period, but will quickly drop off Wednesday night into Thurs as a dry cold front moves through and high pressure settles across the Southeast and adjacent waters. Winds come around to the NW through early Thurs, dropping from up to 20 to 25 kts Wednesday evening down to 5 to 10 kts by Thurs night. Seas will drop from near 6 ft in outer waters down to 3 ft or less by late Thurs. Winds will back around to a more westerly flow into the weekend as the high settles south,. By Sat night into Sunday winds will back farther and will pick up through Sun. May be back in SCA conditions ahead of an approaching cold front late Sun.
