.SYNOPSIS...
High pressure will prevail through the remainder of the holiday
week. A cold front will move through the area early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Quiet conditions continue to prevail across the region this
Christmas, with latest observations showing mostly sunny skies and
temperatures in the mid 60s to lower 70s. Similar to yesterday, will
see these values continue to rise into the afternoon, resulting in
highs in the mid to upper 70s.

Sfc cold front then dives southward along the Atlantic coast late
this evening, perhaps reaching our area prior to daybreak. Outside
of some increasing clouds, expect impacts to remain minimal, as lows
only fall into the lower 50s.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY/...
On Friday, a backdoor cold front should remain just north of the
area during the morning. The front may begin to lift northward as a
clipper dives across the Ohio River Valley during the daylight
hours. Conditions should remain dry with high temperatures ranging
from near 70 across the I-26 corridor to the upper 70s across SE GA.

On Saturday, the center of a 585dm ridge will shift over the eastern
Gulf, with the ridge axis remain just west of the forecast area.
Given mostly sunny conditions and very mild llvl thicknesses,
Saturday is forecast to see some of the warmest temps of the week,
featuring lows in the mid 50s and highs in the mid to upper 70s. In
fact, temperatures may range within 3 degrees of record high
temperatures for Saturday, see Climate section.

By Sunday, the forecast area should remain between high pressure
centered over the western Atlantic and low pressure over the Great
Lakes region. This pattern should provide the forecast area with
light south winds and increasing cloud cover. Temperatures will
remain well above normal, with lows in the low to mid 50s and highs
well into the 70s.

&&

.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
12Z guidance shows a strong cold front remain west of the CWA prior
to sunset on Monday. Monday is forecast to remain very mild with
highs favoring the mid 70s. Physics-based and AI models indicate
that a band of light rain showers may develop along and ahead of the
front on Monday. The forecast will feature 20-30 PoPs for showers.

Conditions should turn sharply cooler for Tuesday and Wednesday. The
coldest conditions forecast for Tuesday night / Wednesday morning,
with low temperatures in the upper 20s to low 30s. The cold
temperatures combined with wind speeds around 5 mph may result in
wind chill values in the low to mid 20s degrees across the inland
counties. LREF probs of wind chill values less than 20 peaks across
inland GA with values around 20 percent.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
18z TAFs: VFR conditions expected to largely prevail this TAF cycle.
That being said, will see some MVFR cigs begin to gradually build in
from the north near/after daybreak as a back door cold front sinks
across the Atlantic coast. Winds look to remain relatively light
during this time.

Extended Aviation Outlook: VFR. Gusty winds are possible on
Monday.

&&

.MARINE...
Tonight: Sfc cold front dives southward along the Atlantic coast
late this evening. Marine concerns are not anticipated at this time,
with seas between 2-3 ft and gusts up to 15 kts.

Friday through Tuesday: Conditions will remain below Small Craft
Advisory criteria through Sunday. Winds will average less than 15
knots with seas 2-4 feet. The main time period of concern is Monday
into Tuesday as a strong cold front approaches and sweeps across the
Atlantic waters. Winds could develop gusts around 25 kts with seas
up to six feet, especially across the outer GA and nearshore
Charleston County waters.
