Area Forecast Discussion National Weather Service Wilmington NC 133 PM EDT Tue Apr 16 2024

SYNOPSIS
High pressure will lead to unseasonably warm and quiet weather through midweek. A series of weak disturbances bring only a slight chance of showers towards later in the week. Rain chances may start to increase later in the weekend, with temperatures gradually starting to fall.

NEAR TERM /THROUGH TONIGHT/
Another unseasonably warm day in store for today with high temps in the upper 80s. A weak front looks to drop down from the north later this morning, stalling across southeast NC before returning north tonight. Latest CAMs and hi-res guidance highlight a window of CAPE 500-1000 J/kg along the front late afternoon into early evening.
Combined with an approaching 500mb weak shortwave, there is a chance for a stray thunderstorm to move across far northern parts of the CWA Main hindrance to convective development is a decent mid level ridge nearby, with stronger subsidence to the south and offshore.
Therefore have capped pops at 15-20%, with any weakness in the ridge allowing for a storm to develop. Low temps tonight again above normal around 60F, with a chance for patchy fog across the Cape Fear region late tonight.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/
Bermuda High on Wed will give way to pre-frontal trough early Thu followed by a dry cold front Thu night. The trough may have some isolated showers with it during the predawn hours of Thu. Deep moisture is limited with precipitable water around 1.10". More importantly there is an abundance of dry air with the only area of RH greater than 80% above 23k ft. However, mid level lapse rates increase to over 7C/km after midnight and the surface based inversion is weak. The trough should be strong enough to force some parcels through the stable boundary layer. Additionally there will be a bit of support at 5h from a very weak shortwave trough. Not expecting a lot of rainfall from any showers that do develop, likely only a couple hundredths at most. Temperatures well above climo Wed and Wed night continue on Thu and Thu night despite the passage of the front. The delay in the arrival of the cooler air and the mixed boundary layer Thu night will contribute to the warm lows.

LONG TERM /FRIDAY THROUGH MONDAY/
The Thu night cold front stalls in the area for the end of the week as the flow aloft remains on the flat side. Brief increase in moisture and a weak, sheared shortwave later Fri help generate convection in the afternoon and evening. Better rain chances develop late Sat and continue into Sun as a strong southern stream shortwave moves east along the Gulf Coast, spreading ample moisture northward.
Abundant deep moisture, convergence along the frontal zone and mid level support/divergence ahead of the shortwave will increase rain chances for the weekend. Rain may linger through the first part of Monday, depending on how strong/amplified the southern stream system is. Temperatures above to well above climo to end the week then highs drop below climo Sun and Mon due to widespread cloud cover and rain. Lows Sun night and Mon night will end up near climo.

AVIATION /18Z TUESDAY THROUGH SUNDAY/
VFR conditions expected through most of the period. The only possible caveats include a few showers and or a TS associated with a back door cold front and MVFR BR in Wilmington. Both are low chance events and maintained the mention of BR mainly for continuity.

Extended Outlook...VFR is expected through the period.

MARINE
Through Tonight: Benign conditions continue across the local coastal waters through tonight, with 10-15 kt SSW winds prevailing. Exception to the prevailing winds will be across northern coastal waters this afternoon and evening, when a weak front is forecasted to drop south into the area and winds turn briefly southeastward.
Seas 2-3 ft today and tonight, combination of SSW wind wave and SE swell.

Wednesday through Saturday: Bermuda High will maintain southwest flow over the waters through Thu. Southwest winds will be 10-15kt with potential for speeds in excess of 15kt for a few hours Wed and Thu afternoon.
A cold front moving in from the northwest sets up a brief period of light offshore flow Thu night into Fri. The front lingers over the waters, keeping winds 10kt or less with varying direction. Seas will generally run 2-3 ft with more widespread 3 ft likely Wed and Thu afternoons. Seas will be a mix of a southerly wind wave and a southeast swell with the swell becoming more dominant as winds decrease and direction becomes more changeable late in the week.
