Area Forecast Discussion
National Weather Service Wilmington NC
324 AM EST Sat Feb 23 2019

.SYNOPSIS...
A warm front will approach from the south today but generally
stall near the coast. Warmer weather is expected Sunday ahead
of a cold front, that will cross the coast during Sunday
evening. High pressure will build in through early next week
with chances of rain increasing later Wednesday into Friday.

&&

.NEAR TERM /THROUGH SUNDAY/...
As of 320 AM Saturday...It's not very pretty when the pineapple
express train runs over the toes of old man winter. One would
see plentiful equatorial Pacific moisture streaming over a pool
of chilly northern stream air, bringing a minimum in sunshine
minutes, and yet, in this case, not all that much rain.

A shallow hill temperature trace today, as readings climb slowly
under clouds, struggling into the middle and upper 50s this
afternoon, a little cooler north of a KLBT to KEYF line. Rain
light, favored today mostly over SE NC. Warm air advection
ramps late Saturday, bringing nighttime temperature climbs into
early Sunday, peaking in abnormal warmth Sunday afternoon, prior
to cold frontal passage. Temperatures take a nice nose dive
Sunday night, 30-35 degrees cooler daybreak Monday from the
balminess of Sunday afternoon.

As both T/Td surge Sunday afternoon, MU/ML CAPE take a jump, and
frontal passage near peak heating will add boost to updrafts in
concert with frontal convergence, and a rumble of thunder could
pop, so slight chance inserted within this narrow window. With
850 winds near 50 knots at this time, not shocking if SPC
upgrades the area to 'marginal' in time, instability aloft being
perhaps a limiter in question, and extent of threat. A few
record highs may be approached Sunday.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
As of 300 AM Saturday...Sunday night into early Monday will bring
high pressure building in from the northwest at the surface while
mid level flow is out of the W or WNW. This will favor clear skies
while temperatures remain fairly seasonable. Later Monday a ridge
axis builds in enough to all but shut down surface winds inhibiting
any additional BL cool advection from reaching the surface even as
the center of the high remains in the Great Lakes. Even so some
radiational cooling will become favored and most places away from
the immediate coast should dip below 40; generally about a category
below the previous night.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 300 AM Saturday... An element of the long term that appears to
offer some degree of certainty is the temperature forecast. Low
amplitude flow not only locally but across much of the CONUS will
mean fairly seasonable weather. Of less certainty is the chance for
rain...though overall they will remain quite low since the
aforementioned mid level flow will not favor deep layer moisture.
Even so, some warm advection isentropic upglide will call for 20
POPs on Wednesday as will a weak cold frontal passage on Thursday.
Uncertainty grows on Friday as models show a flat wave of low
pressure moving west to east across the area possibly bolstering rain
chances.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
As of 00Z...IFR most if not all of TAF cycle, with CIGS OVC003
to OVC009 through majority of period, exception, brief BKN012
in afternoon hours. OCNL DZ/-RA and mist will reduce VSBY to
2-4 SM mainly this morning, and favored from KLBT to KEYF to
KILM. Lowering CIGS and VSBY expected again late tonight, in
light NE SFC winds. NE winds through this morning 7-12 knots,
with gusts at coastal terminals up to 18 knots, winds easing
by afternoon.

Extended Outlook...Sub-VFR will likely prevail early Sunday
before another cold front pushes through lifting to VFR late
Sunday through Wednesday.

&&

.MARINE...
NEAR TERM /THROUGH SUNDAY/...

As of 320 AM Saturday...After a brief lull in wind late today
and tonight, strong S-SW winds to follow in advance of an
approaching and moderately strong cold front. A wind-shift
across the waters to occur late Sunday and SCA flags are likely
ahead of and behind the front. As a result, the wave spectrum
will see decreasing NE waves today, then building SW wind-seas
late Saturday and Sunday. Chaotic seas late Sunday night and
early Monday when residual, large SSW waves, and NE wind seas
on the uptick interact. Isolated TSTMs possible late Sunday
with wind gusts even in showers up to 40 knots.

SUNDAY NIGHT THROUGH MONDAY NIGHT... Cold advection and well-aligned
boundary layer flow will bring strong enough winds that an Advisory
will be needed. Flow remains out of the NW on Monday but as
pressures rise over SC/GA the gradient will ease allowing both wind
and seas to drop below Advisory thresholds. These rising pressures
move further east into the local area later Monday into Monday night
bringing light winds allowing seas to further settle.

TUESDAY THROUGH WEDNESDAY...Winds light and variable on Tuesday
with high pressure moving overhead. With no swell energy to
speak of seas will fall to minimal values. Uncertainty heading
into Wednesday regarding whether return flow develops or a weak
from moves through from the northwest as some major guidance
holds its passage off until Thursday.

&&

SC...None.
NC...None.
