.SYNOPSIS...
High pressure builds across the area through Tuesday, followed
by a cold front Wednesday night. High pressure then returns
heading into the weekend.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
Tonight: High pressure will continue to build into the region this
evening and overnight. Wind gusts will wane early evening, but
strong cold air advection through the night will support northwest
winds in the 10-15 mph range this evening, then around 10 mph from
the north during the second half of the night. Conditions will
remain dry and high clouds will begin to clear from west to east,
setting up a much colder night. Low temperatures are expected to be
in the upper 20s well inland to low/mid 30s along the coastline.
These temperatures combined with a steady wind will likely yield
wind chill values in the mid-upper 20s after midnight. While not
cold enough for a Cold Weather Advisory, these temperatures are
significantly colder than observed the last several days.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/...
Dry and seasonally cool temperatures prevail heading into the new
week as sfc high pressure builds overhead. With the aid of northerly
winds and CAA, only have highs rising into the lower 50s across the
area. Overnight lows will also feel quite chilly, as temperatures
range from the upper 20s inland to mid 30s along the coast. Winds
shift to the southwest by Wednesday, allowing temperatures to
moderate back into the upper 50s to lower 60s.

Upper level ridging digs across the Ohio River Valley Wednesday,
with an attendant sfc cold front also pushing eastward during this
time. As noted in the previous discussion, this boundary is progged
to impact the area Wednesday. While rain chances could begin as
early as Wednesday morning, expect the better probabilities (20-30%)
to occur during the afternoon/evening. Nonetheless, given the lack
of upper level moisture, not expecting to see much in the way of
meaningful rainfall. Rather, the more notable impacts look to occur
Thursday - more on this in the section below.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
Will see a resurgence of CAA Thursday in the wake of FROPA, limiting
highs into the upper 40s to lower 50s, which is certainly well below
seasonal norms. In addition to this, expect west-northwesterly winds
to become fairly breezy. Currently have gusts between 25 to 30 MPH
possible for much of the area Thursday afternoon.

Breezy conditions then subside by Friday as sfc high pressure builds
across the southeast. Otherwise, look for dry conditions to prevail
into Saturday, with temperatures slowly moderating back into the
50s.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
VFR conditions will prevail at CHS/JZI/SAV terminals through 00Z
Tuesday. Northwest winds gusting up to 10-15 kt will weaken during
the next couple hours, then remain below 10 kt under few high clouds
during the second half of the night. Winds then turn northeast and
remain in the 5-10 kt range late morning into early afternoon Monday.

Extended Aviation Outlook: VFR.

&&

.MARINE...
Tonight: High pressure will continue to build across the region in
wake of a cold front departing well to the east. The pressure
gradient will remain tight along the Southeast Coast this evening
with cold air advection persisting across local waters for much of
the night. Northwest winds gusting upwards to 25-30 kt will remain
common across nearshore SC/GA waters and outer GA waters during the
first half of the night. Winds will eventually turn more north and
start to decrease later tonight as high pressure becomes closer
centered to the region and results in a weaker pressure gradient
across local waters. Seas will be slower to respond, but should
generally range between 2-4 ft across most nearshore waters and 4-6
ft across the outer fringes of AMZ350 and outer Georgia waters prior
to subsiding late night/around daybreak Monday. Small Craft
Advisories will remain in effect for nearshore and outer Georgia
waters through the night (outside the Charleston Harbor).

Monday Onward: Winds continue to weaken Monday as sfc high pressure
builds overhead, allowing tranquil marine conditions to prevail
through mid-week. The next chance for Small Craft Advisories will be
Thursday and Thursday night as winds increase behind another cold
front.
