940 FXUS62 KILM 291853 AFDILM Area Forecast Discussion National Weather Service Wilmington NC 253 PM EDT Wed May 29 2024 .SYNOPSIS... Mostly dry and relatively cooler conditions are expected through the end of the week with high pressure dominating. Unsettled weather returns towards early next week as the high moves offshore. && .NEAR TERM /THROUGH THURSDAY/...
-- Changed Discussion --
Dewpoints some 10 degrees lower than yesterday have kept the area rain-free despite the warm afternoon. This same dry advection will preclude fog tonight in a light NW flow regime. This continues into Thursday as high pressure continues to build in from the north. A weak sense of CAA will also keep highs in the low 80s Thursday instead of the upper 80s of the previous few days.

&& .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
-- Changed Discussion --
Quiet short term period. Most notable change is the increase in POPs for NE Pender Thursday night due to a mostly dry cold frontal passage. Precip will be dependent on the return flow around the departing offshore low battling the already dry air in place. Any measurable rainfall will likely be near a tenth of an inch. Could see an increase down the line for early Friday as well should there be any lingering moisture, but still low chances and rainfall amounts. Otherwise, dry conditions under building high pressure. Cloud cover expected to increase Sat, mostly in the form of high clouds, as the center of the high begins to move offshore. Highs in the low to mid 80s with lows in the 50s, coolest Fri night in the mid 50s.

&& .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
-- Changed Discussion --
The center of the high looks to push offshore late Sat into Sun with increasing precip chances. The high looks to settle to our south with moisture funneling in from the SW, leading to diurnal shower and storm chances. This pattern will also lead to steady warming through early next week, with temperatures near to slightly above seasonable norms by midweek.

&& .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... VFR thruout the 12Z TAF Issuance Period. Inverted V soundings with a decent subsidence inversion at 7H which will result in high based Cu field with not much vertical development. Cu field roughly at 6k to 8k bases. NW to N winds at 5 to 10 kt hold thru much of the day, except a pinned sea breeze to mainly affect CRE/MYR with winds becoming onshore, SSE-SSW at or less than 10 kt. The next CFP slated for later this evening, 03z-05z, followed by winds becoming NW-N 5 to 8 kt. No pcpn with this CFP but could observe altocu deck. Extended Outlook...VFR through Sun. && .MARINE...
-- Changed Discussion --
Through Thursday... With a surface front stalled offshore winds will remain light out of the NW this evening. They will turn to the S ahead of the next moisture-deprived boundary later tonight followed by a return of NW flow behind it heading into Thursday. As a stronger high then builds from the north wind speed will increase a category or two. Swell energy remains pretty negligible so today/tonight`s small wind waves will build by a foot tomorrow due to the strengthened gradient. Thursday Night through Monday... Sub-SCA conditions with high pressure moving offshore late this weekend. Light and variable winds will become NEly near 10 kts Fri where they`ll remain until the center of the high moves offshore late Sat. Winds will then be SEly Sun and SWly Mon as the high continues to move away. Seas 1-3 ft.
