Area Forecast Discussion National Weather Service Wilmington NC 346 AM EDT Sat Apr 20 2024

SYNOPSIS
A front will move south across the Carolinas today, stalling to our south tonight. Low pressure developing along this front should lead to widespread rain Sunday. High pressure will gradually build in from the northwest bringing dry weather back to the Carolinas by Monday night and Tuesday and lasting through much of next week.

NEAR TERM /THROUGH TONIGHT/
A cold front will move through the area during the AM hours, stalling near the coast come the afternoon. Low pressure will develop along the front near the SC coast, Gulf moisture being pulled NE into our area. Scattered activity expected during the afternoon due to these increased PWATs paired with instability from daytime heating. Thunder chances will be higher near the coast due to the frontal boundary. Heights continue to fall overnight with precip chances increasing over the area as the low deepens offshore.
Temperatures will be tricky due to the front in the area, but lowered inland temps due to the frontal passage. Regardless, we'll still warm into the 80s, lower 80s inland and upper 80s near the coast. Lows in the mid to upper 50s.

SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/
A cool surface airmass will exist across the Carolinas north of a front stalled near Savannah, GA Sunday. The approach of a southern stream shortwave should lead to increasing isentropic lift over the shallow cool airmass. Rain is expected to overspread the area during the day and forecast PoPs are 90-100 percent. Forecast soundings show mid level lapse rates (above the cool surface layer) are steep enough there may be embedded convective elements within the broad stratiform rain, but I'm not including thunder at this time. I've adjusted temperatures down a couple degrees below the default model blends and will likely end up favoring the cooler GFS MOS for Sunday's highs.

This wave of isentropic lift should taper off Sunday night as this first shortwave passes overhead. Clouds may begin to break overnight, however total clearing will have to wait at least another 24 hours as a northerly stream trough will approach the area Monday.

LONG TERM /MONDAY THROUGH FRIDAY/
The second upper system should help develop an area of low pressure along the baroclinic zone off the GA coast, potentially spreading a few showers back along the Carolina coast Monday. Clouds will also hang on, especially east of I-95. Once this upper trough moves overhead Monday night skies should clear rapidly as the Carolinas come under the influence of surface high pressure moving southeastward from the Upper Midwest. Diurnal ranges will become larger as generally dry weather and clear skies are expected for the second half of the week.



AVIATION /06Z SATURDAY THROUGH WEDNESDAY/
A LIFR/IFR fog bank exists over SE NC, but with encroaching showers these VSBY restrictions may get blown out of the area over the next several hours. Restrictions for NE SC terminals seem to have cleared up but some patchy fog could form near daybreak. Expecting clearing after sunrise with afternoon shower chances.

Extended Outlook... Restrictions possible through the weekend due to daily shower chances from a stalled front. High pressure building in late Mon into Tues should return dominant VFR.

MARINE
Through Tonight...Sub-SCA conditions with a front stalled offshore and deepening low pressure to our SW. Wind direction will be tricky with the front in the area but SW winds during the AM hours will turn to the NE during the evening, speeds near 10 kts increasing to near 15 kts. Seas 2-3 ft with 4 footers creeping in late in the period.

Sunday through Wednesday Night...Sunday morning should start with a stalled front near Savannah, GA extending northeastward across the open Atlantic Ocean. Low pressure should develop along the front off the South Carolina coast during the day, deepening only slowly as it moves out to sea Sunday night into Monday. A surge of northerly winds will develop behind the deepening cyclone, potentially approaching Small Craft Advisory criteria Sunday night into Monday morning. I've added a couple of knots to model blends as nearshore water temperatures have risen well into the 60s and will contrast strongly with air temperatures in the 50s much of the day.

Once this system departs the area Sunday night, a second area of low pressure could develop well off the Georgia coast Monday into Monday night. This could lead to lingering rain over the coastal waters plus breezy northerly winds. Once we get into Tuesday, this second low pressure system should be far enough off the coast for winds to diminish with the approach of high pressure from the west through Wednesday.

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