645 FXUS62 KILM 192351 AFDILM Area Forecast Discussion National Weather Service Wilmington NC 751 PM EDT Sun May 19 2024 .SYNOPSIS... High pressure and drier air will move into the area to start off the work week. Temperatures warm through mid week with rain chances not returning until Friday into the weekend. && .NEAR TERM /THROUGH MONDAY/... Other than the potential for lingering showers into the evening, mainly southern areas, the big question for the near term is when clouds will depart/dissipate. Forecast shows improving skies tonight into Monday but it should be noted that abundant moisture trapped below an inversion in the low levels could delay this process into Monday. Lows tonight should fall to the upper 50s to lower 60s with highs Monday in the upper 70s to lower 80s. && .SHORT TERM /MONDAY NIGHT THROUGH THURSDAY/... Dry weather continues for the duration of this period as sfc high pressure over the Carolinas gradually shifts east and offshore through the week, with weak mid-level ridging in place. This will allow for increasing temps each day...highs mainly in the low 80s Tuesday rising to around 90 by Thursday. Otherwise, expect daily sea breezes with skies averaging mostly sunny/clear. && .LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/... Low chances for rain return with shortwave energy passing through the fairly zonal flow aloft. Daily sea breeze will also aid in afternoon convection with a warm and moist airmass in place. PoPs are consistent each day (20-40%) with the fairly stagnant pattern in place. Some guidance (e.g. 12Z ECMWF) even keeps it dry most days with shortwave energy staying just off to the north. Temps remain slightly above normal with highs averaging in the mid/upr 80s. && .AVIATION /00Z MONDAY THROUGH FRIDAY/...

Low stratus has been slowly lifting and dissipating the last few hours. This trend will continue and only MYR is reporting MVFR ceilings. MYR should rise to VFR within the next hour and VFR is expected at all sites overnight. There is low chance for MVFR/IFR ceilings developing around daybreak, given low level moisture, but the relatively short duration of night this time of year decreases the potential. There will be too much wind/mixing overnight for fog. Northeast winds continue Monday as high pressure builds down the coast with VFR conditions prevailing. Extended Outlook...VFR will dominate with early morning vis or cig restrictions possible each day.

&& .MARINE... Through Monday...Expect NE winds of 10 to 15 KT tonight and Monday with 20 KT possible nearer 20 NM on Monday. Seas will generally run 2 to 4 FT through the period, though 2 footers will be confined to areas sheltered from NE flow Monday. Monday Night through Friday...Sub-SCA conditions will continue. Sfc high pressure over the Carolinas slowly slides farther offshore through the week, with southerly flow becoming established Wednesday afternoon through Friday, no higher than 10-15 kt. After 2-4 ft seas Monday night, expect only 1-3 ft heights with a weak ESE 9-10 second swell component for the remainder of the week. && .ILM WATCHES/WARNINGS/ADVISORIES...
