000 FXUS62 KILM 241900 AFDILM Area Forecast Discussion National Weather Service Wilmington NC 300 PM EDT Wed Apr 24 2024 .SYNOPSIS...
-- Changed Discussion --
A weak backdoor cold front will bring only minor rain chances this evening. High pressure will build in from the north for Thursday through Saturday with dry weather expected. A warming trend will develop early next week as the high shifts to off the southeast US coast.

&& .NEAR TERM /THROUGH THURSDAY/...
-- Changed Discussion --
A weak cold front resides to the northwest as delineated by the narrow band of cloud cover and showers. The latest guidance offers up no compelling reasons to move the forecast of low chance pops either way thus no changes with some showers possible this evening. Some stratus or fog is possible in the wake of the boundary as the push is minimal. Thursday offers up mostly sunny conditions with highs ever so slightly moderated to the middle 70s or so.

&& .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
-- Changed Discussion --
Surface high pressure will maintain control while shifting across New England through the end of the week and then southward to off the Mid-Atlantic coast by the end of the period. Aloft, the mid-level pattern will transition away from weak troughing as a ridge over the central US sharpens and shifts overhead by the end of the period. This will yield a mainly dry forecast with passing low and high clouds at times as areas of enhanced moisture move overhead. With high pressure to our north and northeast, winds will favor easterly and allow for a healthy sea breeze to make good inland progress. Temperatures will follow a gradual warming trend as 1000-500mb thicknesses increase with the arrival of ridging aloft. Expect highs in the low-mid 70s on Friday and mid-upper 70s on Saturday with lows mainly in the low-mid 50s both Thursday night and Friday night.

&& .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
-- Changed Discussion --
Surface high pressure looks to settle off the southeast US coast for the remainder of the period while mid-level ridging remains firmly in place until a shortwave trough shunts it away between Tuesday and Wednesday of next week. Overall, this keeps a mainly dry and sunny forecast in play with little to no forcing for ascent and no notable surge in moisture. However, with the high off our coast, expect rising temperatures as south to southwesterly low-level flow takes over on Sunday night and persists thereafter. The aforementioned shortwave trough should drag a decaying cold front across our area around midweek, but rain chances are looking meager at this time due to sparse moisture and weak forcing. Temperatures start out near normal on Sunday with highs in the upper 70s to around 80 and nighttime lows in the mid-upper 50s. They take a turn above normal for the first half of next week as the high settles nearby, bringing high temps into the low-mid 80s with some upper 80s possible well-inland and upper 70s along the coast. Nighttime lows look to hold in the low 60s.

&& .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... Overall VFR conditions should prevail through the period. A few showers could move across sites this evening with a cold front but impacts should be minimal. A minor concern continues for some BR in the wake of the boundary as the push is modest at best. Extended Outlook...There is a low potential for MVFR to IFR visibility in ground fog Friday morning. && .MARINE...
-- Changed Discussion --
Through Thursday... A modest southwest flow of 15-20 knots will remain in place for a few more hours then shift to offshore in kind of a distorted mess later tonight. Officially the direction will be from the north Thursday but don`t be surprised at some erratic directions as speeds/forcing will be meager. Significant seas will be 2-4 feet well into tonight trending downward from there to 2-3 feet. Thursday night through Monday... ENE winds at the start of the period will hold steady at around 10-15 kts while gradually veering towards the ESE as high pressure shifts across New England, then down the East Coast. Expect a definitive shift to southerly flow by late Sunday or Sunday night as the high settles off our coast. Seas look to remain in the 2-4 ft range through the period, with a surge of 3-4 ft E to ENE swells with a period of 10 sec arriving over Thursday night into Friday morning and continuing into Sunday. These swells scale back to 2-3 ft for late Sunday through Monday while southerly 1-2 ft wind waves become more prominent. No headlines are expected through the period.
