522 FXUS62 KMHX 031944 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 344 PM EDT Mon Jun 3 2024 .SYNOPSIS... High pressure remains off the coast through midweek. A backdoor front will move into the area on Tuesday and stall through Wednesday morning. The weak front will lift back north Wednesday as strong cold front approaches from the west. The front will move through Friday, with cooler and drier conditions expected for the weekend. && .NEAR TERM /TONIGHT/...

As of 3 PM Monday...Showers have started to blossom along the seabreeze as it moves inland. Surface high pressure centered offshore has kept us under warm and moist southwesterly flow. A mid- level trough is sliding offshore while an embedded shortwave is rounding its base. With weak forcing in place, shower and thunderstorm coverage will be scattered through this evening. MLCAPE is ample over the coastal plain (1500-2000 J/kg) but effective shear is fairly weak (20 kt or less). Although the severe threat is low given the lack of shear, any stronger storms that develop could produce heavy rainfall, gusty winds, and small hail. Precip chances will diminish after sunset and given our consistent southwesterly winds today, lows will stay in the upper 60s.

As of 3 PM Monday...With surface high pressure over the northeast US, a backdoor cold front will sag south into the area Tuesday. This, along with the afternoon seabreeze, will serve as the forcing mechanisms to support more shower and thunderstorm activity. Similarly to today, coverage will likely be isolated in the morning, become scattered by the afternoon, and diminish after sunset. It`ll be quite toasty with highs nearing 90 across the coastal plain with the beaches just slightly cooler in the low-80s. As for severe potential, the threat is low given weak effective shear (20-25 kt) and forcing. Despite these limiting factors, 1000- 1500 J/kg of SBCAPE would still make it possible for some stronger storms to develop with threats of heavy rainfall, gusty winds, and small hail.

As of 240 AM Mon...Unsettled conditions expected through Thursday with near seasonable temps. A backdoor cold front moves into Eastern NC Tuesday, likely stalling through Wednesday morning, and providing a focus for scattered shower and thunderstorm development. Front lifts back to the north Wednesday, with high pressure strengthening offshore. Increasing southerly flow will bring a surge of moisture into the area through late week with more unsettled conditions through Thursday. A cold front will move through Friday, bringing drier conditions late week into the weekend. Another frontal system may impact the area early next week. Wednesday through Thursday...The stalled frontal boundary will lift back north early Wednesday with cold front approaching from the west and high pressure strengthening offshore. This will allow rich moisture (PWATs 1.75-2") to advect in from the west ahead of a potent upper level trough and strong cold front. Increasingly unsettled conditions are likely with a diurnal max in coverage each afternoon, capped pops at high chance for now, with greatest coverage likely Thursday afternoon and evening. Weak shear will limit svr threat, though an isolated strong storm with gusty winds, small hail and heavy rain will be possible. An increase in heat and humidity is also likely as highs climb into the upper 80s to low 90s each afternoon, and it will feel like 95-100 degrees out when factoring the humidity. Friday through Sunday...Cold front looks to move through Friday, though still some uncertainty with respect to timing. 00z guidance shows upper troughing lingering along the east coast through the weekend, depicting drier and slightly cooler conditions across eastern NC. Another frontal system may impact the area early next week.

&& .AVIATION /20Z MONDAY THROUGH SATURDAY/... SHORT TERM /through Monday night/... As of 1:45 PM Monday...Predominantly VFR conditions are expected through the next 24 hours. However, brief periods of MVFR CIGs are possible wherever scattered convection develops during the afternoon and evening hours today and tomorrow. Winds will be out of the SW at 5-10 kt through the period. LONG TERM /Tuesday through Friday/... As of 240 AM Mon...Unsettled conditions expected this week, with best chances for showers and storms Wednesday and Thursday. This could bring some periods of sub-VFR conditions to the terminals. && .MARINE...

SHORT TERM /Through Monday night/... As of 3 PM Monday...Southwest winds at 10-15 kt will turn slightly more westerly tomorrow morning and decrease to 5-10 kt. By tomorrow afternoon, they`ll be back to the southwest at 10-15 kt. Waves will be around 2 ft through the period. Scattered showers and thunderstorms are possible through the period but most of the activity will reside over the coastal plain and Gulf Stream. LONG TERM /Tuesday through Friday/... As of 240 AM Mon...Good boating conditions expected through Wednesday with light to moderate winds. The pressure gradient will tighten Wednesday night into Thursday with SCA conditions possible. A backdoor front may push into the northern and central waters Tuesday, then lift back north Tuesday night and Wednesday. The front will likely bisect the coastal waters into Wed morning, with winds north of the boundary E-SE 10 kt or less, while south of the boundary winds expected to remain SSW 5-15 kt. SSW winds will increase to 15-20 kt Wednesday night, becoming SW 15-25 kt Thursday. The cold front will move through Friday, with gradient relaxing and winds becoming WSW 10-15 kt. Seas will be mostly 2-3 ft through Wednesday, building to 3-6 ft Thursday, then gradually subsiding to 2-4 ft Fri.
