Area Forecast Discussion National Weather Service Wilmington NC 224 PM EDT Sat Apr 19 2025

SYNOPSIS
High pressure continues to bring dry conditions and summer like temps through early next week. This high pressure finally breaks down by next Tuesday, allowing for a frontal system with increased rain chances to slowly approach and possibly stall across the region during the mid to late week period of next week. Temperatures continue to be unseasonably warm.

NEAR TERM /THROUGH SUNDAY/
Warm temperatures continue with high pressure offshore and a ridge to our south. Boundary layer winds remain elevated again tonight and we are unlikely to see fog development outside of shallow ground fog in areas that are sheltered or dominated by peaty soil. Lows in the lower 60s.

Copy and paste on Sunday plus a degree or two inland. Highs in the mid and upper 80s, cooler behind a healthy sea breeze near the coast. Skies will be mostly clear outside of fair weather cumulus and high clouds mainly west of I-95.

SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/
Quiet and warm forecast continues under surface high pressure and mid-level ridging just offshore. More cirrus clouds stream in, but doesn't play much of a role in the sensible weather.
Lows Sunday night in the upper 50s to near 60 become the lower 60s Monday night. Highs Monday won't have a problem getting well into the low-to-mid 80s. Differential heating between land and water allows for a healthy seabreeze to kick up in the afternoon, which caps the highs at the immediate coast to the upper 70s.

LONG TERM /TUESDAY THROUGH SATURDAY/
An upper low in the Great Lakes region pushes northeastward into Ontario and Quebec, which pushes the mid-level ridging further south towards the Florida Atlantic coast. Lingering trough energy from the low helps push a weak cold front towards the area Tuesday, before stalling out through at least Thursday.
Moisture parameters look rather impressive, but the associated forcing and shear vorticity is lackluster. Rain chances are on the rise, particularly by Wednesday and Thursday, where the forcing looks best (such that it is). Scattered showers and storms are possible in the afternoon, resembling more of a summertime pattern. Old frontal boundary may try to lift northward as a warm front sometime late next week or towards the weekend. This brings down the rain chances slightly, but not zero. Temperatures hold steady, with highs in the mid-to-upper 80s inland, upper 70s at the coast with the seabreeze. Lows each night in the low-to-mid 60s.

AVIATION /18Z SATURDAY THROUGH THURSDAY/
High confidence in VFR through the 12Z TAF period. Gusts this afternoon approaching 20 knots. Boundary layer winds remain elevated tonight hindering fog development.

Extended Outlook... High confidence in VFR through the weekend.
Increasing rain chances could bring restrictions beginning Tuesday.

MARINE
Through Sunday...Offshore high pressure maintains SW winds through Sunday. Winds turn southerly during the afternoon as a sea breeze develops, gusts near the coast to 20 knots. Winds will generate a steady 2-3 foot wind wave.

Sunday Night through Thursday...Benign marine conditions continue, with SSW winds at 10-15 kts likely through Wednesday night. By Thursday, winds will try to back to the southeast.
Seas stay locked in at 1-3 ft, with more light chop likely during the seabreeze each afternoon. Outside of wind waves, a southeasterly swell clocks in at 7-9 seconds.

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