Area Forecast Discussion
National Weather Service Wilmington NC
1032 PM EST Sat Jan 11 2020

.SYNOPSIS...
Unseasonably mild temperatures will prevail through the weekend
with southerly winds ahead of a cold front. Rain chances will
increase  tonight and Sunday as the front approaches. Wet and
mild conditions will continue early next week with the front
stalled in the area. Another cold front on Thursday will bring
cooler weather late next week.

&&

.UPDATE...
Evening update includes severe thunderstorm watch for counties
along and west of I-95. Latest radar shows line of thunderstorms
to the west of I-95 moving rapidly towards the I-95 corridor
with a history of producing damaging winds. Thunderstorm watch
is in effect until 2 AM EST.

&&

.NEAR TERM /THROUGH SUNDAY NIGHT/...
A few warm advection showers moving north across the region have
been hard pressed to lead to measurable rain and that will likely
remain the case through sundown. It is then the 00-06Z window during
which rain chances increase, though high res guidance like the RAP
and HRRR don't agree as to the exact location. A line of showers is
forecast to develop offshore and move into either the Grand Strand
area (HRRR) or the Cape Fear region (HRRR); all while rain chances
gradually increase from the west. This is also the window of time
when wind fields strengthen to the extent that may support isolated
tornado spinups despite the overall absence of deep convection. The
very narrow ribbon of deep moisture aligns right at the coast
towards 12Z but then washes back across our entire CWA for the
remainder of the period. Wind fields will have weakened by then but
there is a better chance of instability in the 1000-1500 J/Kg range.
Thunder will remain in the forecast through Sunday but the severe
threat will have shifted well to our north.

&&

.SHORT TERM /MONDAY THROUGH MONDAY NIGHT/...
The rapid weakening and northward trajectory of the current
system will lead to an interesting scenario for the short and
part of the long term periods. The front associated with this
system will near the coast before stalling and even moving
northwest through the short term period. This is usually a
summertime scenario and I'm not sure I have seen this in
January. Regardless, showers and even a rogue thunderstorm or
two will be fair game through the period. There appears to be
little organization to the activity so QPF amounts will be muted
and somewhat erratic. The warm thermal profiles remain in place
leading to highs in the 70s Monday and lows mainly above 60.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
The unsettled nature of the short term period with a broad
southwest flow will remain in place for Tuesday and Wednesday.
Broad brush chance pops remain in place for these periods but in
time the short term and certainly near term periods will offer
more detail as the relatively weak forcing is leading to diffuse
QPF generation. A cleansing cold front will move across
Thursday with dry and cooler conditions developing. Another
system could affect the area at the end of the period.

&&

.AVIATION /04Z SUNDAY THROUGH THURSDAY/...
Rain chances increase significantly towards 06Z and some terminals
may approach LLWS criteria though the surface winds will remain
quite gusty as cold front approaches the region. The main frontal
line of showers will enter the area from the west around daybreak
Sunday. Though this line will be capable of producing strong winds
they will be hard pressed to produce much thunder.

Extended Outlook...A stalled front will remain in the area Sunday
through Tuesday, accompanied by occasional rain and MVFR ceilings.
Very localized sea fog with IFR visibility and ceiling may affect
the CRE and MYR airports during onshore wind through Tuesday.

&&

.MARINE...
Frontal boundary approaches from the west but also stalls to our
west. This will gradually ease the gradient as we progress through
Sunday and Sunday night, below advisory thresholds in fact. Seas
however will take a bit longer to drop below 6 ft and they will be
the deciding factor of when the flags can be lowered. The high
dewpoints that have advected into the area should be supportive of
sea fog but there is considerable discrepancy between various
guidance regarding its onset and severity. Have hedged towards the
slower and less severe solutions as the wind will likely have to
partially relax to favor its formation.

Basically a summertime pattern in place with a southwest
flow at most levels through about Wednesday. Winds will be southwest
at 10 knots or so while seas will be 2-4 feet with maybe a few five
footers mainly early. Sea fog will probably be the main issue for
this period as the pattern is conducive for such. A cold front will
move across late Wednesday or early Thursday morning with a stronger
offshore flow developing. Winds and seas will increase but most
likely remain well below any headline criteria.
