Synopsis
A cold front will bring a mix of rain and snow, and will clear
the coast late tonight. Cold and dry arctic air, will spread
into the region through Thursday. Temperatures will warm into
the weekend as high pressure moves offshore. Another cold front
will bring rain chances by Monday evening, but little cooling,
and temperatures are expected to remain above normal into next
week.

Near term through today
As of 900 pm Wednesday... Much of the moisture has scoured out
across the ilm cwa, well ahead of the upper closed low. This
potent closed low will move across the fa late this evening and
overnight with continued limited moisture across the fa. Some
atlantic moisture will be drawn in, however areas north of the
ilm cwa, from CAPE lookout northward, will be the beneficiaries.

Basically, will have to rely on the dynamics of the upper
closed low and it's accompanying moisture, which is not much.

Due to the moisture dilemma, we have downgraded the winter storm
warning to a winter weather advisory for those 2 counties. Have
continued the winter wx adv for the 4 inland counties. Due to
the limited moisture, have lowered the total snow accumulations
to 1 to 2 inches across the northern periphery and that's being
very generous, elsewhere, looking at 1 inch or less for the
those 4 counties within the initial winter wx adv.

Wind chills by morning will be in the upper single digits well
inland. Any further decrease in temps and or higher wind gusts
would produce wind chill advisory numbers which is 5 degrees or
less.

Previous... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... .

As of 300 pm Wednesday... A winter storm warning continues for
marlboro and robeson counties, and a winter weather advisory
remains in effect for darlington, marlboro, bladen, and pender
counties.

Goes-east water vapor is showing the mid-level trough moving
into the western carolina's. At the surface the cold frontal
boundary is entering into the western portions of the forecast
area. The 2 pm observations is showing rain over most of the
forecast area. The latest hrrr is showing the best chances of
snow in the western half of the area after 3 pm and will slowly
make it to the coast. Timing for the coast appears to be after 8
pm. With the dry air it appears after the initial shot of
precipiation that we will see light snow or flurries well after
midnight.

Also, with delay in the system making eastward have extended the
warnings and advisories to 1 am. Also, for areas south of the
warning and advisory area will have to watch for black ice as
any liquid precipiation that does fall will likely freeze.

As the storm pushes off the coast, winds will increase and
combined with the low temperatures will see wind chills in the
the 8 to 13 degree range around sunrise Thursday. This is just
above the wind chill advisory criteria.

On Thursday skies will clear but temperatures will struggle to
get to 40 degrees with brisk winds.

Short term tonight through Friday night
As of 300 pm Wednesday... The mid level pattern will have
evolved into a split flow regime initially and translate into a
southwest flow ahead of a mid level low by Saturday morning.

Although seemingly busy at the mid levels, surface high pressure
will be the dominant feature. This high will move across the
gulf of mexico then out into the atlantic by the end of the
period. Once again a temperature forecast throughout and expect
lows Friday in the lower to middle 20s. Highs Friday will
rebound into the 50s.

Long term Saturday through Thursday
As of 300 pm Tuesday... The chief caption this period "warming
trend". Even in wake of a cold front early next week, minimal
cold air advection is seen, as the upper pattern sees a SE atlc
upper ridge gradually expand NW into the area. A weak cold pool
aloft meanders eastward along the gulf coast this weekend and
offshore by Monday, will little sensible weather impacts here.

As a result, much of next week may feature sunshine and 60s in
the afternoons, likely feeling like an early spring compared to
the recent weather pattern. Aside from late Monday and early
Tuesday, this entire period will maintain a dry column and low
pwat values. The coldest period, will be Saturday morning, near
freezing, the mildest, perhaps just ahead of the cold front
Monday into the upper 60s by afternoon. Tuesday looks to be the
breeziest day in wake of the cold front, with w-nw breezes.

Aviation 06z Thursday through Monday
As of 06z... Patches of very light snow should move out of the
myrtle beach and wilmington area by 08z. Low clouds still
blanket the area currently, but I expect skc to develop inland
(lbt and flo) around 08z, spreading down to the coast (ilm, cre,
myr) around 10z. Breezy northwest winds could gust to 20 knots
at times early this morning. Skc will continue tonight with wind
speeds diminishing.

Extended outlook...VFR.

Marine
Near term through Thursday ...

as of 930 pm Wednesday... Continued the SCA timeline for all
waters. The NW offshore winds have begun increasing across the
local waters and should breach SCA thresholds after midnight.

The cfp followed by a tightening sfc pg combined with arctic
air advection, will result in NW winds 20-25 kt with gusts up
to 30 kt possible overnight through midday thu. At the moment,
significant seas are responding and have increased 1 to 2 ft
during the past hour. The dominant 3 foot ese ground swell at
10-12 second periods for the past few days will give way to
building wind driven waves that will overtake the dominance
held by the ground swell.

Previous... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... .

As of 300 pm Wednesday... Currently winds are from the east with
seas running 3 to 4 feet. This will change quickly as the
front and a developing low shifts to the northeast off the
coast. Winds are expected to reach 20 to 25 knots late this
evening and seas will increase to 5 to 7 feet. The winds will
weaken and with an offshore flow the seas should settle back out
to 3 to 5 feet by Thursday afternoon.

Short term Thursday night through Friday night ...

as of 300 pm Wednesday... Surface high pressure will move from
the northern gulf of mexico to well offshore during the period.

Between this feature and the general cyclonic flow to the north
a west to southwestern flow will prevail across the waters. Wind
speeds will be fairly uniform in a 10-15 knot range leaning
moreso toward the higher end early then the lower end late.

Significant seas will generally fall into a 2-3 foot range.

Long term Saturday through Monday ...

as of 300 pm Wednesday... Welcoming and friendly marine
conditions this period, particularly in wake of recent weather.

As high pressure slips offshore by the weekend, a milder return
sw flow will prevail, with seas 3 feet or less, and even 1-2
feet at times, with winds less than 15 kt. Seas will begin to
build Monday as sustained SE fetch offshore, starts pushing wave
energy toward our coast. By Monday night seas of 4-5 ft in 7
second intervals, may be rolling in. No tstms this period, but a
few rain showers can be expected Monday night, as a cold front
crosses the coast. Inshore water temperatures were in the upper
40s to lower 50s.
