Area Forecast Discussion National Weather Service Wilmington NC 634 AM EDT Mon May 20 2024

SYNOPSIS
High pressure maintains dry conditions through the first half of the work week. Temperatures warm through mid week with rain chances not returning until late Thursday into the weekend.

UPDATE
No big changes with the latest update. Some low clouds/fog are expected west of Wilmington through around daybreak. However, another area of low clouds moving in from the northeast could impact the Wilmington area as well.

NEAR TERM /THROUGH TONIGHT/
Dry high pressure will maintain control as it ridges southward into the area. This will bring lower than normal temps into southeast NC and northeast SC with highs today close to 80 most locales and lows tonight mainly in the mid to upper 50s. Some low-level moisture advecting into the area and trapped beneath the nocturnal inversion this morning and again tonight will likely yield some low clouds/fog. Think the better chance of fog will be tonight though given lighter low-level winds.

SHORT TERM /TUESDAY THROUGH THURSDAY/
Shortwave ridging aloft aligns itself across the east coast through the period with persistent surface high pressure. This will lead to dry conditions through the short term period with a warming trend.
Some sources of forecast uncertainty could be cloudiness and lows Tuesday night as the center of the high looks to nudge NE. This could allow flow around the high to bring in stratus overnight, which would inhibit radiational cooling despite calm winds. Still lowered temps in our colder spots slightly. Otherwise, light onshore flow becoming more SW by the end of the period. Highs warm from the lower 80s to near 90; Lows near 60 warming into the mid 60s.

LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/
High pressure moves offshore ahead of a shortwave Thurs night.
Forcing clips the northern part of the area with low rain chances. A cold front will then approach through the end of the week. The temperature forecast is a bit difficult as it will depend on how far south this front pushes. Current trends show that it will stick north of the area, so have risen temps slightly from previous forecast. Spotty forcing aloft paired with enhanced moisture will support increased shower/storm chances through the end of the period.

AVIATION /12Z MONDAY THROUGH FRIDAY/
Generally VFR for the 12Z TAF period, although some low clouds/fog are possible this morning, mainly through around daybreak, and again late tonight.

Extended Outlook...VFR will dominate but early morning vis/cig restrictions possible each day. Also, showers/storms also possible starting Thu night.

MARINE
Through Tonight...High pressure to the north will maintain gusty northeast winds into this evening before some improvement overnight.
Seas will also be elevated up to 5 ft, mainly due to wind waves but also some mixed swells, but overall conditions should stay below Small Craft Advisory levels.

Tuesday through Friday Night...Sub-SCA conditions under predominant high pressure with increasing rain chances Thurs night. Onshore flow AOB 10 kts becomes more SW 10-15 kts by Thurs. Seas 2-3 ft becoming more 2 ft by Wed. Swells SE at 9-10 sec with a decreasing NE swell 7- 9 sec.

ILM WATCHES/WARNINGS/ADVISORIES
NC...Beach Hazards Statement through this evening for NCZ108.
SC...Beach Hazards Statement through this evening for SCZ056.
MARINE...None.
