Synopsis
High pressure will prevail through the weekend. A cold front
will move through the region Monday night into Tuesday morning,
followed by more high pressure through the middle of next week.

Near term until 6 pm this evening
No changes were made for the sunrise update.

High pressure will extend across the region today as a strong,
southern stream shortwave digs across the pineywoods of east
texas. The cold, arctic airmass will begin to steadily moderate
as weak warm air advection combines with full insolation. After
a very cold start to the day, highs should recover into the
upper 50s as 850 hpa temperatures warm to around 7.5c and
1000-850 hpa thicknesses rise to around 1340m by late afternoon.

Would not be surprised to see a few 60 degree readings,
especially south of the i-16 corridor.

Short term 6 pm this evening through Monday
Tonight: clear skies will give way to increasing thin cirrus
late as the subtropical jet buckles north ahead of southern
stream shortwave energy propagating across the lower mississippi
valley. This should have little impact on overnight lows where a
decoupled boundary layer will support another night of strong
radiational cooling. Expect lows to bottom out in the upper 20s
inland, lower 30s at the coast with mid 30s at the beaches.

Saturday: the mid upper levels will consist of low pressure over the
deep south in the morning. This low will move eastward and weaken,
passing overhead late Saturday night. At the surface, high pressure
will hover over the southeast. There will be increasing high clouds
associated with the low. Otherwise, large scale subsidence and a
lack of moisture will lead to dry conditions. Southwest winds should
allow temperatures to rise a few degrees above normal during the
day, then dropping to near normal at night.

Sunday: the mid upper levels will consist of a low over the
southeast in the morning. This low will move eastward and weaken
through the day. At the same time a disturbance will move into the
plains states, allowing the flow over our area to become
southwesterly. At the surface, high pressure will hover over the
southeast in the morning, barely shifting offshore by the overnight
hours. Dry conditions will prevail. A moderating air mass combined
with mostly sunny skies will allow temperatures to rise above normal
during the day, then remaining above normal at night.

Monday: the mid upper levels will consist of a trough approaching
the mississippi valley, allowing southwesterly flow to prevail over
our area. At the surface, high pressure offshore in the morning will
move away while a cold front approaches from the mississippi valley.

The front and it's precipitation are expected to hold off until
mainly the nighttime hours. However, some models hint at maybe a
light shower or two far inland late in the day. We have slight
chance pops to cover this potential. Regardless, most locations will
be dry. Despite increasing clouds, warm air advecting into the
region will allow temperatures to rise well above normal.

Long term Monday night through Thursday
The cold front will move through the region Monday night into
Tuesday morning, bringing a brief bout of rain. High pressure will
quickly build in behind the front Tuesday afternoon, bringing dry
conditions. The high will prevail into Wednesday. Models start to
diverge on Thursday, but the general consensus points towards a low
rainfall risk.

Aviation 12z Friday through Tuesday
Primary concerns:
* none.

Vfr.

Extended aviation outlook: flight restrictions are possible with a
cold front Monday night into Tuesday morning.

Marine
Today: there are no concerns. West winds this morning will back
to the southwest this afternoon and increase slightly. Speeds
will remain less than 15 kt with seas 1-2 ft nearshore and 2-3
ft offshore.

Tonight: southwest winds will once again veer to the west
overnight. Speeds will similarly remain less than 15 kt with
seas 1-2 ft throughout.

Saturday through Tuesday: tranquil conditions will prevail through
the weekend as high pressure hovers over the region. A cold front
will move through the region Monday night into Tuesday morning,
bringing a brief increase in winds seas. High pressure will build
behind the front later Tuesday.

Equipment
The kclx radar is out of service until further notice. Repairs
are ongoing. Adjacent radars include: kltx, kcae, kjgx, kvax and
kjax.

The downtown charleston observation site (chls1 kcxm) remains
out of service until further notice.

Chs watches warnings advisories
Ga... None.

Sc... None.

Marine... None.
