435 FXUS62 KILM 240558 AFDILM Area Forecast Discussion National Weather Service Wilmington NC 158 AM EDT Mon Jun 24 2024 .SYNOPSIS... Hot and humid weather will continue along with scattered thunderstorms as a weak front stalls across the Carolinas this week. && .UPDATE... Coastal flood advisory for Downtown Wilmington and the lower Cape Fear River has ended. && .NEAR TERM /THROUGH TODAY/... Isolated activity ongoing has finally started showing some lightning and thunder. Showers and storms are slow-moving and should stay non- severe, migrating more towards the coast this evening. Isolated activity could remain at the coast overnight as well as some low clouds. Warmed lows near the coast, but unsure how thick the cloud deck will be and how long it will linger overnight. Mid 70s inland with upper 70s near the coast. Tomorrow could see the threat for severe weather as a cold front approaches the area. The front should be pushing into the area around the morning along with a line of showers and storms which will make the high temp forecast difficult with increasing cloudiness. Went a bit warmer with the SW flow ahead of the line, highs in the mid 90s. Heat indices could near advisory thresholds in some areas but with the incoming precip around the same time opted to not put one out at this time. Instability is near 2-2.5k but still not looking like much deep layer shear for storm organization. Seeing a bit of an inverted V in the soundings and with mixing to around 800mb isolated damaging winds and some hail can`t be ruled out in stronger storms. The line should shift towards the coast by the end of the period. && .SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/... Pops will linger into Monday evening via a cold front and mid level trough. The boundary will get bogged down or dissipate through Wednesday with pops being more confined to southern zones Tuesday. By Wednesday a more seasonal sea breeze boundary will be the main catalyst for showers and thunderstorms. While there is almost no cooling in the wake of the front some slightly lower dewpoints will decrease heat concerns Tuesday with moisture recovery Wednesday bringing the possibility of headlines back into play. && .LONG TERM /THURSDAY THROUGH SUNDAY/... Decent pops remain in the forecast for Thursday and Friday although the coverage and or intensity have taken a hit in recent medium range model cycles. Although the mid level trough and front are decent enough it appears the trough is advecting relatively dry and stable air from the massive ridge out west that extends into the Gulf of Mexico. Next weekend seems to offer more of a sea breeze/isolated pulse convection set up. Temperatures will be on the warm side of climatology but probably just short of any headline criteria. && .AVIATION /06Z MONDAY THROUGH FRIDAY/... Showers and onshore flow will keep MVFR potential near the coast overnight, although this appears to remain periodic. IFR is possible along the Grand Strand prior to sunrise. Hot temperatures developing during the day should help develop a broken eastward-moving line of thunderstorms Monday afternoon, potentially affecting KFLO and KLBT as early as 17-18z, then moving down to the coast a couple hours later. High-res model blends show the highest risk for convective impacts occurring at the KILM airport between 19z-22z where low visibility in heavy rain has a moderate potential to occur. Extended Outlook... VFR should prevail outside of periodic MVFR/IFR during diurnal showers/thunderstorms plus spotty morning low clouds/fog. && .MARINE... Through Monday... Small Craft conditions should be met in both gusts and seas tonight with questionable ending time as the 6ft seas look to take a bit longer to leave our outer waters. Current advisory is running through Monday morning. Isolated strong storms may move over the waters Mon PM ahead of a cold front but winds should stay SW through the period. Monday Night through Friday... Residual southwest winds of 10-15 knots late Monday are seemingly the strongest of the week as a cold front pushes across briefly. A brief and weak offshore flow will then develop followed by south to southeast winds ten knots or so through late week. Significant seas will be 2-4 feet. && .TIDES/COASTAL FLOODING... Other - Rip Currents: A high risk of rip currents possible for the Brunswick County and Northern Horry County Beaches for Mon with a gradually decreasing risk of rip currents Tue and Wed for all county beaches. For today, a strong south to north longshore current expected across Pender and New Hanover County Beaches. This may need to be expanded to other county beaches for Mon as modest SSW to SW winds continue, possibly increasing ahead of an approaching cold front. && .ILM WATCHES/WARNINGS/ADVISORIES... NC...High Risk for Rip Currents from 6 AM EDT this morning through this evening for NCZ110. SC...High Risk for Rip Currents from 6 AM EDT this morning through this evening for SCZ054. MARINE...Small Craft Advisory until 11 AM EDT this morning for AMZ250- 252-254-256. && $$ SYNOPSIS...ILM UPDATE...21 NEAR TERM...LEW SHORT TERM...SHK LONG TERM...SHK AVIATION...21 MARINE...SHK/LEW TIDES/COASTAL FLOODING...
