Area Forecast Discussion National Weather Service Wilmington NC 653 AM EDT Sun Apr 21 2024

SYNOPSIS
Clouds and widespread rain are expected behind a cold front today. Clearing skies should arrive during the day Monday as high pressure advances eastward. Warmer temperatures on Tuesday and Wednesday should cool behind another cold front Wednesday night. The front should return north late in the week.

UPDATE
No major updates to the forecast made at this time.

NEAR TERM /THROUGH TONIGHT/
Resolution of the front is a bit tricky right now but there's certainly drier air moving in from the north, maybe a bit less noticeable at the coast currently. Majority of the activity is showers near the coast with a larger swath of rain to our west which will move towards the area through the morning. With some guidance showing instability lingering near the coast left small thunder chances through the morning but could see this being overzealous.
More stratiform precip expected for the afternoon as the main swath of precip moves overhead along with a shortwave trough. With this shortwave moving offshore tonight the rain will come to an end around midnight, but the main trough will still be approaching from the west, providing some enhancement. Rain chances may stick around longer at the coast because of this. Otherwise, temperatures will also be difficult, highs likely happening early this morning with decreasing temperatures throughout the day amidst rain and clouds.
Highs largely in the mid 60s, a bit cooler inland and a bit warmer near the coast. Lows in the mid to upper 40s with continued cloudiness overnight.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/
An impressive upper trough will push eastward across the Carolinas during the day Monday. Even though the surface front will be located hundreds of miles offshore, there will be lingering mid level moisture up above 700 mb that could lead to a little light rain along the coast during the morning hours.
Forecast PoPs are only 20-30 percent and any clouds and precipitation should end as the trough axis aloft pushes overhead during the day. Inland areas should clear out by noon but it may take another few hours to get full sunshine to reach the coast Monday. Forecast highs are in the low-mid 60s, coolest at the coast.

High pressure moving across the Mid South should reach the Carolinas late Monday night, providing good radiational cooling within an already cool and dry airmass. Surprisingly (given how warm it was this weekend) lows should fall deep into the 40s all the way down to the beaches. Normally colder inland spots could dip into the 30s, although the risk of frost should remain low in populated areas.

The surface high will move offshore Tuesday afternoon with a weak seabreeze keeping the beaches several degrees cooler than inland areas: upper 60s versus lower 70s. With the high nudging farther offshore Tuesday night lows should moderate to 45-50, except lower 50s on the beaches.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
The passage of a strong upper system across New England on Wednesday should push a cold front southward, reaching the Carolinas Wednesday night. Heavily modified Canadian maritime air streaming in behind the front will likely hold Thursday's highs in the lower 70s inland with upper 60s the beaches.

A large swath of southerly winds developing in advance of the next synoptic low over the northern Plains late in the week should lift the front northward, again allowing warmer and more humid air to spread across the Carolinas. The timing on this airmass transition is quite uncertain however: the 00z Canadian and ECMWF are at least 24 hours quicker than the 00z GFS. This brings particular uncertainty to temperatures Friday afternoon into Saturday since the retreating front may have a 10-15 degree temperature gradient along it. Rain chances are no higher than 10 percent given ridging aloft and W-NW mid level flow.

AVIATION /12Z SUNDAY THROUGH THURSDAY/
Unsettled weather will lead to restrictions through the 12Z TAF period in the form of LIFR/IFR VSBYs/CIGs. Tried to improve timing on some restrictions but it's going to be showery probably through the morning with hit or miss restrictions. Rain will become more widespread through the afternoon as the main axis moves overhead, moving offshore towards midnight. VCSH could stick around at coastal terminals with conditions improving towards the end of the period as drier air starts to settle in.

Extended Outlook...Flight categories gradually into Monday morning. High pressure building in late Monday through Thursday will return dominant VFR.

MARINE
Through Tonight...A stalled front will lead to rainy conditions over the waters today. NNE winds will increase to near 15-20 kts during the afternoon as the PG tightens due to a disturbance aloft, but gusts are expected to stay just below SCA thresholds at this time.
Seas 3-5 ft.

Monday through Thursday Night...This morning's cold front should be located a few hundred miles off the Southeast coast Monday morning. Low pressure developing well east of Savannah along the front should drag down a 15-20 knot north wind with gusts to 25 kt across our coastal waters Monday, strongest south of Cape Fear. This is just shy of Small Craft Advisory criteria. After collaboration with NWS CHS we'll mention an SCA is possible Monday but will not raise an advisory at this time.

High pressure moving eastward across the Mid South should reach the coastal Carolinas late Monday night into Tuesday. Gradually weakening northeasterly winds are expected as the high approaches, then veering southeasterly Tuesday afternoon as the high moves offshore. Increasing southwest winds are expected Wednesday as the high moves offshore.

A cold front moving southward along the Eastern Seaboard should reach the Carolinas Wednesday night, veering wind directions north to northeasterly for Thursday.

ILM WATCHES/WARNINGS/ADVISORIES
NC...None.
SC...None.
MARINE...None.
