Area Forecast Discussion
National Weather Service Wilmington NC
1033 PM EDT Fri Jun 13 2025

.SYNOPSIS...
Bermuda High Pressure remain in place over the next several days.
Warm and humid conditions will prevail along with the potential
for showers and thunderstorms each day, mainly in the afternoon
to early evening. A warming trend is expected during the
upcoming week.

&&

.UPDATE...
Convection still hanging on in the Pee Dee region. Once again
adjusted pops upward in these areas. No other changes.

&&

.NEAR TERM /THROUGH SATURDAY/...
A moderately unstable airmass will remain in place through the near
term. Afternoon convection will produce brief heavy downpours into
early evening before loss of heating allows things to settle down.
Expect decreasing activity from south to north after 00Z tonight,
with PoPs falling below 15% after 03-06Z. Small perturbations in SW
flow aloft will aid in convective initiation beginning early
Saturday, increasing in coverage as daytime heating gets underway.
Will continue with a range of generally 60-80% PoPs Saturday,
perhaps a little lower along the coast as the sea breeze pushes
inland. Lows tonight will be held above climo...mainly low-mid
70s...while highs Saturday should be capped in the mid 80s given
numerous showers/tstms.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
Unsettled weather will continue through the period, with the
afternoon hours featuring the most radar returns. With such high PW
values in place only weak forcing will be needed to produce fairly
widespread showers and thunderstorms. That forcing will come in the
form of copious mesoscale boundaries as well as a weakening
shortwave passing by to our north. What such a pattern does though
is make highlighting any particular area for seeing precipitation
difficult. Timing-wise though the coastal locales should see POPs
first as the seabreeze activates quickly with such a warm morning
start. Inland locales will then see POPs ramp up in the afternoon as
instability develops.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
Thunderstorm coverage to remain elevated on Monday with high PW
values and weak steering flow still in place. Things should start to
change on Tuesday as the mid level ridge just east of FL starts to
poke a ridge axis into the SE US. This weak subsidence paired with
the fact that it will start to channel shortwave energy further
north will lead to a decrease in rainfall coverage, though it will
still be above normal due to the deep layer moisture. As this
continues into Wednesday a more normal distribution/coverage of
storms appears likely while afternoon temperatures creep up a degree
or two each day.

&&

.AVIATION /03Z SATURDAY THROUGH WEDNESDAY/...
Persistence forecast in place for aviation concerns the next 24
hours. This calls for tenuous VFR conditions initially dropping
to IFR and or below inland by early Saturday morning. For now
coastal sites appear to remain VFR but trends in time will need
to be monitored. Convection fires again late Saturday morning
into the early afternoon with all sites fair game.

Extended Outlook...Brief restrictions due to intermittent
thunderstorms are possible through Wednesday.

&&

.MARINE...
Through Saturday...SSW winds on the order of 15 kts will persist
tonight and Saturday as Bermuda high pressure remains in place.
Showers and thunderstorms should remain isolated across the waters
through the evening hours, becoming a little more prevalent late
tonight and through Saturday. Seas will be generally 3 ft, with 4
footers in the outer waters and in the vicinity of Frying Pan
Shoals.

Saturday night through Wednesday...  Bermuda high pressure will keep
wind direction fairly unchanging and from the SW and in the 10-15kt
range through about Tuesday. An inland surface trough may add a few
kt of wind speed thereafter. Wave bulletins show seas remaining in
the 3-4 ft range with a 5 second wind wave the more dominant
compared to the 8-9 second SE swell.

&&

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