Area Forecast Discussion
National Weather Service Wilmington NC
349 PM EDT Wed Jun 2 2021

.SYNOPSIS...
A large area of high pressure will import copious moisture into
the Carolinas over the next several days bringing some much
needed rainfall. Rain chances linger but lessen over the weekend
as temperatures rise slightly; this pattern lasting into early
next week.

&&

.NEAR TERM /THROUGH THURSDAY NIGHT/...
Deep moist southerly flow around strong offshore high pressure will
keep the weather unsettled through Thursday night. Scattered showers
with isolated thunderstorms across inland areas will continue until
around sunset. Focus overnight will shift back to southeast NC as
axis of greatest moisture shifts eastward. Tomorrow will be a repeat
of scattered showers early before axis of moderate rainfall shifts
inland Thursday afternoon.

As an upper trough approaches the area late Thursday, 0-6km shear
strengthens around the I-95 corridor as the day progresses.
Therefore if any storms get deep enough to tap into the stronger
shear, which is a low chance, could see an isolated strong storm or
two develop and far inland counties are in a marginal risk for
severe weather. Cloud cover is forecasted to be abundant enough to
inhibit deep convection. A weakening front approaches from the west
Thursday night with scattered to numerous showers, and isolated
thunderstorms, expected to move from west to east late Thursday
night into Friday morning.

Total forecasted rainfall is around 0.75-1.5" through Thursday
night. Given nature of expected shower coverage, some spots
could receive a bit more while others could receive much less.
Humidity remains elevated as dewpoints hover around 70 degrees
through, at least, Thursday night. Low temps tonight and
Thursday night around 70, with highs Thursday in the low 80s.
Like today, temperatures will fluctuate quite a bit Thursday
depending on cloud breaks and where rain cools the area.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
Precipitable water values around 1.75" Friday though down from the
day before still represent the 90th percentile with respect to
climatology. Rain chances will remain in the likely category area-
wide. There may be a late day decline along the coast as the marine
layer marches inland but a veered flow aloft compared to days
previous will make this a slower process; will show this trend but
to a lesser degree than what was possible on a day like
today/Wednesday. Daytime highs will be close to normal because its
very hard to maintain overcast skies this time of year and we always
end up with enough insolation even between fairly widespread
showers. Based upon this assumption a small but non-zero severe
weather threat will develop late Friday afternoon as some mid level
dry air advects in coincident with some very weak PVA and even
some moderate 0-1km SRH.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
The main mid level trough axis swings through Saturday with just
weak training impulses that call for low end chance POPs area-wide
while an increase in insolation favors temperatures a few degrees
above climatology. The GFS may call for re-evaluation in its
depiction of a NW flow event-but it also looks like it suffers from
convective feedback. Similar highs slated for Sunday and with a
narrow ridge axis building overhead our 20-ish POPs appear just
fine. Monday through Wednesday the mid level ridge will poke up ahead
of the system opening up out of TX/OK. The pattern will become
pretty non-progressive and locally we should see a continuation of
warm weather with isolated to perhaps scattered mainly diurnal
thunderstorms i.e. early June weather.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
Most of the convection this afternoon will be inland. A crack of
thunder is possible. Tonight, the HRRR has been consistent with
convection refiring after midnight, affecting mainly the coastal
terminals. Showers and storms are expected on Thursday, nearly
any time of the day.

Extended Outlook...Flight category restrictions are possible in
scattered showers and thunderstorms tonight and Thursday, and
from possible ground fog Thursday morning. Rain chances continue
through the end of the week.

&&

.MARINE...
Through Thursday Night...With strong high pressure offshore, deep
southerly flow continues through Thursday night with scattered
showers and isolated thunderstorms throughout the forecast period.
Best chances for rain over coastal waters will likely be in the
overnight to early morning hours. Winds out of the south 10-15 kts
tonight and Thursday, with slight increase in speeds Thursday night
as a weak front approaches. 3-4 ft seas tonight will slowly increase
to 4-5 ft by Thursday night as SE wind wave builds.

FRIDAY THROUGH MONDAY...West atlantic high pressure sprawling on
Friday bringing pretty typical SW flow locally. And while it doesn't
move much Friday night into Saturday a moderate mid level trough
passing by to our north will lower pressures over land, weakening
the gradient over the waters allowing for an easing trend in both
wind and seas. With a little SE swell lingering due to the
aforementioned large oceanic high waves will only fall into the 2-3
ft range (in the absence of the swell with such paltry wind fields
we'd be looking at 2 ft or less).
