960 FXUS62 KILM 301752 AFDILM Area Forecast Discussion National Weather Service Wilmington NC 152 PM EDT Thu May 30 2024 .SYNOPSIS... A dry cold front that moves through early this morning will be followed with dry high pressure that sticks around through the weekend. Temperatures will linger near seasonal norms before the high pressure pushes offshore next week, bringing a gradual warming trend and a return of daily shower and thunderstorm chances. && .NEAR TERM /THROUGH TONIGHT/... No longer 90 degree readings slated for this period or thru the upcoming weekend. Will be under the influence of troffing aloft with air masses dropping down from Central Canada across the Great Lakes to the ILM CWA. Looking at max temps today in the 80-85 range and tonights lows in the 60-65 range with mid 60s along the immediate coast given SSTs in the 70s. CFP during the pre-dawn Thu hrs has resulted in frisky NNW-NNE winds across the FA. CAA and even drier air with sfc dewpoints dropping into the 50s, mixing this aftn may drop them temporarily into the 40s west of the I-95 corridor. The CAA turns neutral by this aftn and the sfc pg relaxes. An embedded s/w trof tracks around the longwave upper troffing late tonight which will bring down re- enforcing CAA and dry air as high pressure again ridges in from the Great Lakes. The dynamics associated with this s/w trof will remain and pass by N thru NE of the area late tonight with no pcpn making it this far south but still could observe mid- level clouds. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... Quiet forecast period ahead, with high pressure dominating as it scoots over from the Ohio River Valley to offshore of the mid- Atlantic. Highs Friday in the lower 80s, increasing by 2-3 degrees Saturday. Lows Friday night in the mid 50s inland to near 60 at the coast, bringing a much cooler and drier feel to the air than we`ve seen in the last couple of weeks. Lows rebound a bit Saturday night, generally in the upper 50s to near 60. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... High pressure slowly moves further offshore throughout the long term period, setting up more consistent return flow to the area. Temperatures increase a bit each day, with some highs approaching 90 inland by Tuesday. The return flow increases moisture and cloud cover throughout this time. There`s no significant changes in the upper steering flow or forcing, which means that only mesoscale features will dominate. In other words, slight chances for afternoon showers and storms gradually come back into play, although this activity does not look all that impressive. Shower and thunderstorm chances may start to look a bit better by Wednesday, when shortwave energy rolls in from the west. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/...
-- Changed Discussion --
VFR conditions will continue through the period. A slight secondary surge very late tonight from the north is worth noting in the official TAFs but outside of this nothing of significance. Extended Outlook...VFR through Sun. Isolated convection Mon could result in brief MVFR.

&& .MARINE... Through Tonight...The next CFP will occur during the pre-dawn Thu hrs and should be offshore by sunrise. Will see a mini-surge NNW-NNE surge, below SCA thresholds, but could see gusts 20+ kt at times thru the morning as CAA, drier air and a temporary tightened sfc pg interact. By mid-aftn, the sfc pg relaxes and winds go vrbl in direction at 1 kt or less except for the possibility of a weak sea breeze near shore into the early evening. Sfc high pressure from the GReat Lakes to re-enforce itself across the waters by the end of this fcst period with another mini NE surge likely after sunrise Fri. Seas generally around 2 ft or less, except up to 3 ft from the mentioned surges. Wind waves will dominate the "power factor" during the mini-surges with the SE swell at 8+ second periods dominating all other times. Friday through Monday...Benign marine conditions continue through the extended forecast period. Winds at 5-10kts gradually veer this period, going from northerly Friday morning, to northeasterly Friday afternoon, to ESE Saturday, to SSW Sunday and Monday. Seas at 1-2ft gradually increase to 2-3ft later in the weekend. && .ILM WATCHES/WARNINGS/ADVISORIES... NC...None. SC...None.
