Synopsis
Clouds and occasional rain will continue today into tonight as
a final area of low pressure develops across the eastern
carolinas. A little snow could mix in late tonight into Tuesday
morning as precipitation ends, but no accumulation is expected.

Temperatures will remain below normal Tuesday through Thursday
as high pressure moves across the carolinas. Another low
pressure system should bring more rain Friday and Saturday.

Near term through tonight
As of 300 am Monday... A cold and dreary Monday expected today as highs
remain stuck in the upper 30s inland to lower 40s along the coast.

Temperatures this chilly are approaching 20 degrees below
climatology in many places. This is a result of low pressure off the
coast associated with yesterday's wind rain event. Moderate
northerly flow on the west side of this system continues to drag
cold air into the carolinas. Atop the surface layer is easterly low
level warm advection isentropic upglide to keep the clouds socked in
and also leading to a gradual ramping up of some light rain, with
northern zones being favored over southern. Surface and low level
trough then sink southward away from the region later tonight and
the sense of thermal advection switches to cold. As the moisture
wanes towards daybreak the precipitation will be capable of mixing
with snow flurries as it shuts off. The lack of any warm layer will
preclude freezing precipitation while the diminishing ascent and
available moisture precludes any chance of accumulation.

Short term Tuesday through Wednesday night
As of 300 am Monday... The last strong shortwave aloft should be
exiting the coast around sunrise Tuesday. The back edge of the
deeper moisture up should push offshore between 8-10 am, taking
any lingering light precipitation out to sea. As low-level cold
advection continues there is some concern about what form
lingering precip might take. The 00z NAM has a fairly cold low-
level profile that would support snow, or at least a snow rain
mix Tuesday morning. The 00z ECMWF and GFS show a continuing
warm nose centered on 925 mb (~2500 feet agl) that would melt
falling hydrometeors to rain. In either case surface air temps
could be very close to freezing in burgaw, wilmington, and
southport. Fortunately any precip falling Tuesday morning
should be very light, perhaps just trace amounts, with dry
weather developing even at the coast by late morning.

Skies should be clear inland by 10 am, with clear skies
developing for the grand strand and CAPE fear area by early
afternoon at the latest. Highs Tuesday should only reach the
upper 40s to around 50, a good 10 degrees below normal.

Surface high pressure centered along the gulf coast will build
eastward Tuesday night and will reach the carolinas on Wednesday.

Large diurnal ranges are expected Tuesday night into Wednesday
with lighter winds and clear skies. Lows should fall into the
20s almost down to the beaches Tuesday night, and highs Wednesday
to rise to 51-55 degrees. The high will nudge offshore Wednesday
night, allowing a return flow to begin, with lows 30-35 except
warmer near the beaches.

Long term Thursday through Sunday
As of 325 pm Sunday... High pressure will shift across the
region on Wednesday and a wedging pattern develops on the lee
side of the appalachian mountains and a coastal trough front
develops Wednesday evening into Thursday. A strong mid-level
trough drops down over the red river area on Thursday and will
work its way across the the mid- atlantic coast by late weekend.

At the surface, a strong low pressure area develops over the
ark-la-tex Thursday and swings eastward up the appalachians
mountain chain. This will put our area in the warm sector on
Friday and a good chance of rain with thunderstorms on Friday
into Friday night. The weekend will dry out.

A warming trend is expected ahead to the surface front on Friday
with temperatures dropping back a bit on the weekend. Maximum
temperatures in the lower 50s on Wednesday will warming into the
lower to middle 60s on Friday before settling back into the 50s over
the weekend. The low temperatures will be in the lower to middle 30s
Wednesday night and they will warm into the lower 40s to lower 50s
for the remainder of the forecast.

Aviation 06z Monday through Friday
As of 06z... Ifr ceilings now appear more likely both area-wide as
well as through the TAF duration. Low levels remain very saturated
in NW flow behind storm system exiting off to the ne. Above the
shallow layer of saturation the atmosphere is very dry. Measurable
rainfall not expected initially but visibility-restricting dz will
be possible. Upper disturbance may cause radar to light up with
light rain towards daybreak mainly over northern zones but appears
to warrant mention at all terminals.

Extended outlook... MVFR Mon evng tues fri.VFR Wed thur.

Marine
Near term through tonight ...

as of 300 am Monday... Advisory flags to be flying for the
duration as well as beyond. Slow moving low pressure off the the
northeast slow to exit due to strengthening energy aloft
through midday today. Chilly high pressure sprawled across the
eastern u.S. Paired with the offshore low will keep the gradient
moderately strong locally supporting both advisory-worthy wind
and seas, the former continuing out of the north.

Short term Tuesday through Wednesday night ...

as of 300 am Monday... The final area of low pressure in our
strong weekend storm system will exit the coast early Tuesday,
allowing high pressure along the gulf coast to build eastward
across the carolinas on Wednesday. Breezy offshore winds and
considerable large backswell from the offshore low on Tuesday
will necessitate an extension of the small craft advisory. By
Wednesday wind speeds should die down below 10 knots with seas
falling to only 1-3 feet.

Long term Thursday through Friday ...

as of 325 pm Sunday... High pressure will move over the waters
and will transform into the classic coastal trough and wedging
high pressure on the lee side of the appalachians pattern. Winds
will begin this period from the northwest at 10 to 15 knots and
will become light and variable as the coastal trough develops.

Winds increase from the southeast at 15 to 20 knots on Friday
and seas will increase with a small craft advisory expected
again of Friday.

Climate
As of 300 am Monday... Wilmington's rainfall Sunday amounted to
1.22 inches at the airport, pushing the annual total to a new
all-time record of 97.67 inches. Additional rainfall today &
tonight could add another tenth of an inch to this total. This
would leave us roughly 2.2 inches short of 100 inches for the
year. Looking ahead toward the next storm system late in the
week, a tight rainfall gradient is expected along the coast as
maritime instability could play a role in precipitation
distribution. Latest wpc progs indicate around 2 inches possible
Thursday through Friday night.

Odds are looking very good we'll break the 100-inch barrier in
wilmington. See https: weather.Gov ilm raceto100 for details.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
