Synopsis
High pressure will move east across the region through Monday. A
cold front is expected Monday night. Another cool area of high
pressure will dominate the weather for much of the upcoming
week.

Near term through Sunday night
As of 300 pm Saturday... An exceptionally dry airmass across the
carolinas has seen dewpoints fall as low as 12 in florence and
whiteville, 13 at north myrtle beach, and 18 in wilmington. Deep
vertical mixing over 5000 feet today is tapping into reservoir of
bone dry air up within the subsidence inversion aloft. Surface
dewpoints should recover quickly this evening once the nocturnal
inversion begins to develop.

High pressure will move directly across the area tonight. Clear
skies, calm winds, and a very dry atmospheric column should provide
ideal radiational cooling. The airmass isn't particularly cold (925
mb temps +7c, 850 mb temps: +5c) but with such good radiational
cooling I expect to see surface temperatures fall well below these
925 and 850 mb readings. The GFS mos has shown a very warm bias the
past two nights, and I am discarding its output in favor of a
nam ECMWF blend. This gives low temps in the mid 30s for wilmington,
whiteville and florence, and upper 30s in southport, north myrtle
beach, and georgetown. Locations across interior southeastern north
carolina that typically are much colder on good radiational nights
should see lows near freezing, and i've issued a freeze warning for
robeson, bladen, and inland pender counties, with a frost advisory
for columbus, inland brunswick, and marlboro county sc.

Sunshine and weak warm advection behind the departing high should
allow temps to rise into the upper 60s to lower 70s away from the
beaches Sunday. Increasing high level moisture will manifest itself
as thickening cirrus Sunday night. This plus a developing 25-30 kt
low level jet should keep Sunday night's lows near 50.

Short term Monday through Monday night
As of 300 pm Saturday... Rain chances will be spreading west to east
across the area on Monday as a cold front approaches. Some guidance
is faster than at this time yesterday but the WRF still holds off
until 00z. A little instability appears to linger this late so
isolated thunder still appears possible especially once the front
arrives. Afternoon temperatures will shoot up very quickly into the
70s while behind the front temperatures will drop into the mid 40s
as gusty northerly winds keep the atmosphere mixed. Rainfall amounts
will be rather paltry and tend to average a quarter of an inch or
less save for possibly higher amounts under deeper convective
elements.

Long term Tuesday through Saturday
As of 300 pm Saturday... High pressure to make slow progress across
the region through the midweek period brining a few days of
unseasonably cool weather including two nights with frost potential
over inland nc (tue and wed). Low pressure develops well offshore on
Wednesday into Thursday but will be too far east to bring any
weather other than a breezy day along the coast. The high moves
overhead Friday while some weak mid level ridging and solar
insolation bring a warmer afternoon. Saturday brings a slow
transition to a prefrontal flow regime.

Aviation 18z Saturday through Thursday
As of 18z...VFR throughout the period as high pressure builds over
the area. A deep mixed layer will keep winds around 10 knots
from the NW and lead to a few gusts; winds will become calm
overnight.

Extended outlook...VFR conditions expected through early next
week as high pressure builds over the area. MVFR and perhaps ifr
conditions could develop late Monday into early Tuesday as a
front moves across the carolinas.

Marine
As of 300 pm Saturday... 1028 mb high pressure will move almost
directly overhead tonight. Northwest winds that blew 10-20 kt most
of the morning are weakening this afternoon, and a modest seabreeze
may even develop shortly. Winds will become light north to
northeasterly overnight as the high approaches. East winds Sunday
morning will veer southerly Sunday afternoon as the high moves
offshore, and southerly winds should continue Sunday night. Compared
to the rough conditions of the past several days, there should be
excellent weather conditions for mariners coming up.

Short offshore fetch lengths have helped seas come down to only 1.5
to 2.0 feet nearshore, and 3 feet at the frying pan shoals buoy
offshore. Seas should average only 1-2 feet over the coming 36 hours.

Monday through Monday night: southwesterly winds expected as cold
front approaches from the northwest. The boundary's approach will
cause winds and seas to build Monday night and it's passage late
Monday night will cause a sharp veer that will steepen wave faces.

Conditions will become hazardous enough with FROPA that an advisory
appears likely.

Tuesday through Thursday: long period of unsettled weather expected
for the long term. Initially winds and seas both meeting
advisory thresholds in the cool surge following Monday night's
fropa. But soon thereafter low pressure developing slowly
offshore to keep the local gradient tight enough to keep small
craft advisory in effect.

Ilm watches warnings advisories
Sc... Frost advisory from 2 am to 9 am edt Sunday for scz017.

Nc... Freeze warning from 2 am to 9 am edt Sunday for ncz087-096-105.

Frost advisory from 2 am to 9 am edt Sunday for ncz099-109.

Marine... None.
