Area Forecast Discussion
National Weather Service Wilmington NC
233 PM EST Thu Dec 24 2020

.SYNOPSIS...
Increasingly mild, breezy and humid weather will precede a
strong cold front. The front will bring a chance of severe
thunderstorms later today. By Christmas Day and early on
Saturday, the coldest air of the season will overspread the
region. A slow warming trend is expected into early next week
with seasonably cool temperatures much of the upcoming period.

&&

.UPDATE...
Tornado Watch # 518 has been issued for all of the ILM CWA
except for Marlboro and Darlington Counties. The adjacent ILM
Coastal Waters are also included in the Watch Area.

Previous 1228 PM EST UPDATE...
Based on latest 88D reflectivity trends and latest HRRR and
other near term hourly models, have re-aligned the POPs,
particularly the categorical POPs associated with the 2 areas
of pcpn for the remainder of today thru tonight. The 1
associated with the SE-S wind convergent boundary currently
moving across the FA. And the approach of the more widespread
pcpn ahead of the approaching cold front. Will highlight the
severe tstorm threat in conjunction with the latest SPC enhanced
area.

Previous 828 AM EST UPDATE...
Raised a Wind Advisory for the immediate coast and inland
coastal counties of Southeast NC.

Ongoing forecast was right at the cusp of a Wind Adv for the
aforementioned area. With the FA already entrenched in the warm
sector and the projected wind dynamics in the lower levels this
aftn and evening, the wind advisory is a plausible way to go
especially with plenty of loose holiday decorations out and
about.

Have increased the seas slightly based on latest progged winds
and resulting seas. Ie. The better fetch given the southerly
trajectory time line.

&&

.NEAR TERM /THROUGH FRIDAY/...
As a strong cold front sweeps across the Carolinas, it will increase
the chances of severe weather this afternoon into the evening with
possible damaging winds and isolated tornadoes.  The synoptic
setting is showing a deep 500 mb trough from the Great Lakes into
Texas. This trough will move into the Ohio Valley by 12 UTC Friday
with a 125 knot Jet moving across the Carolinas late Thursday. At
850 mb, the low-level jet will approach speeds of 50 to 60 knots.

The HREF shows the mean Cape between 500-1000 J/Kg along the coast
with the maximum cape values extending 50 to 75 miles inland. The
SRH range between 200-300 m2/s2. The updraft helicities indicate
most of the updrafts, mainly east of a Little River to western
Pender County.  Chances for a Tornado Watch for late afternoon seem
to be certain. As mentioned earlier, the one unknown impact will be
the marine layer influence of weakening convection along the coast.

Wind will increase by mid-morning and will reach the maximum values
later this afternoon into the evening. South to southwest winds will
increase to 25 to 30 mph with gusts of 40 to 45 mph outside of the
convection. These wind speeds are just below wind advisory criteria.
After the front/convection moves off the coast, cold air advection
will occur, and a significant cooldown will occur and remain through
next Monday.

Highs are expected to reach into the lower 70s today, and the lows
on Christmas morning will be 32F inland to upper 30s at the coast.
Highs will struggle to make it to 40 inland and the lower 40s on the
coast.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
An arctic airmass will be in place for the weekend and slowly
modify by the end of the period. There may be some high clouds
that drift across moreso later in the period but certainly no
pops. Not surprisingly temperatures will be below normal the
entire time with lows in the middle 20s with some isolated
colder readings in the usual spots. Highs will struggle to reach
the 40s once again Saturday but should see better moderation
Sunday with lower 50s or so.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
The extended period will remain relatively quiet with only a
weak and mostly dry system moving across late Monday. Both the
GFS and ECMWF have been consistent in all but drying out this
system completely. Temperatures will warm up a bit Monday only
to be reset in the wake of the front Tuesday followed by another
modest warmup ahead of the next system well to the west.

&&

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
Conditions starting to deteriorate as the cloud deck lowers more
into MVFR, with IFR in convection. The strong cold front will
continue to push through the Carolinas this afternoon through
tonight. With instability, showers and thunderstorms are likely
to be in the area from 18-04Z. LIFR conditions are expected
with the convection. Also the 850mb jet increases to 60kts and
low-level wind shear will be likely with values approaching
50-55kts from the SSW. Slow clearing is expected after 04Z
inland to 05Z at the coast. VFR returns early Friday morning,
with westerly gusts to 20-25kts.

Extended Outlook...VFR, with clearing with strong north winds
Friday. Wind easing Saturday.

&&

.MARINE...
Through Friday:
A strong cold front will quickly approach the coastal waters
today and move off the coast this evening. Winds speeds are
expected to reach Gale Warning conditions with south to
southwest winds of 30 knots and gust of 40 to 45 knots over the
waters. A squall line will cross the waters this evening, and
waterspouts are possible.

This morning, the wave heights of 4 to 5 feet are expected
to build to 5 to 6 feet in the nearshore waters and 9 to
13 feet 10 to 20 miles off the coast.

Friday Night through Monday:
A westerly flow of 15-20 knots initially will slowly decrease
through the weekend as arctic high pressure drifts slowly to the
east and more than anything modifies. Some residual significant
seas of over six feet will probably keep a Small Craft Advisory
in place for a few hours into early Saturday but otherwise seas
will settle into a 2-4 foot range. Relatively tranquil
conditions are expected next week with only a couple of wind
shifts with seas remaining on the modest side.
