Area Forecast Discussion National Weather Service Wilmington NC 146 PM EDT Sat Apr 27 2024

SYNOPSIS
High pressure will build in from the north through tonight. A warming trend will develop early next week as the center of the high shifts to off the southeast US coast. A cold front will approach the area late next week, increasing rain chances.

NEAR TERM /THROUGH SUNDAY/
500 mb ridge axis will remain oriented N-S across the Carolinas through Sunday. The resulting NW flow along the eastern seaboard will cause surface high pressure to drop from the New England states to off the SE NC coast by Sunday evening. The surface high is producing onshore flow along with enough low- level convergence to pop a few showers across SE NC and across the Pee Dee region this afternoon. However weak instability, shallow moisture and a capping inversion will keep convection low-topped. Ridging aloft will maintain benign weather through Sunday, with overnight lows mid/upper 50s and Sunday highs in the upper 70s to around 80.

SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/
Sfc high pressure will take up residence over the southeast coastal waters with a S to SW return flow developing. Meanwhile an amplified mid to upper level ridge will align itself up the east coast. This will produce plenty of subsidence and unseasonably warm temperatures across the region with highs close to 80 on Sunday most places and into the low to mid 80s on Monday. Temps closer to the coast will in the mid 70s Sun, but the veering of winds to a more SW direction on Mon should keep temps a few degrees warmer on Monday. Model soundings show some potential for some aftn cu on Sun with moisture under the subsidence inversion around 5k ft. Monday looks drier in the lower levels with only a bit of cirrus around. Overnight lows will be warming as well with readings in the mid 50s most places on Sun night and around 60 Mon night. Overall, a dry and unseasonably warm period.

LONG TERM /TUESDAY THROUGH FRIDAY/
Sfc high pressure will remain anchored off of the southeast coast through midweek. The mid to upper ridge up the east coast will shift eastward with a passing shortwave late Tues into early Wed followed by ridging once again for late Wed into Thurs. The shortwave should kick off a few shwrs late Tues through Tues night with trough passing through the area and offshore by Wed morning. This will be the only minimal chc of rain until a front approaches toward the weekend. Overall, expect a warm week with temps running several degrees above normal with mid 80s for highs most days and above 60 for lows.

AVIATION /18Z SATURDAY THROUGH THURSDAY/
Onshore flow around surface high pressure is generating some low-level convergence and a few light showers that may impact KFLO and KLBT through 21Z. Otherwise VFR. Easterly flow this afternoon gradually veers as high pressure slides southward through Sunday.

Extended Outlook...Predominately VFR expected through early next week outside of a low chance of morning fog or low cigs each morning.

MARINE
Through Sunday: High pressure will drop southeastward from New England to off the Carolina coast through Sunday. Easterly winds will veer to the south by late Sunday. Speeds should remain generally 10-15 kt, although a sea breeze circulation will produce some 20 kt gusts within a few miles of shore. 3-4 ft seas will primarily be composed of a ESE swell around 7 sec.

Sunday night through Wednesday...
Winds will veer around from S Sun night to SW Mon into midweek as high pressure shifts south over the adjacent waters and takes up residence off of the Southeast coast. Winds will back slightly and spike up a bit in the sea breeze each afternoon.
Seas will start out 2 to 4 ft, but will settle to 2 to 3 ft through most of the week ahead. A longer period easterly swell will mix in.

ILM WATCHES/WARNINGS/ADVISORIES
NC...None.
SC...None.
MARINE...None.
