Synopsis
Atlantic high pressure will weaken through Tuesday. A weak cold
front will stall over or near the area on Wednesday. Another
cold front will move through Friday night into Saturday followed
by drier high pressure Sunday.

Near term /until 6 am Tuesday morning/
Early this evening: showers and thunderstorms have come to an
end with the loss of diurnal heating. A few showers continue to
develop back to the west and southwest, ahead of an approaching
mid-level shortwave. This feature is currently making its way
across alabama and into georgia where it is helping to drive
much deeper and more significant convection. This will be the
main forecast issue overnight, tracking this shortwave as it
progresses eastward and whether it is able to kick off isolated
noctural convection across the forecast area. Models do show the
shortwave weakening a bit, but virtually ever available model
shows some degree of convection moving along a region near where
the lowcountry and midlands meet. Coverage should be limited
thanks to the lack of surface based instability, but there
should be enough elevated instability to generate at least
isolated showers. Have kept thunder in the forecast as mid-level
lapse rates steepen. Potential for fog appears to be on the low
end thanks to enough flow in the low levels just off the
surface. Another mild night with lows only falling to around 60
for most areas.

Short term /6 am Tuesday morning through Thursday/
The upper shortwave will be moving off the sc coast by early
Tuesday afternoon, taking with it the best chance for showers
and tstms. We maintained a slight chance for precip across far
northern areas where the better forcing will exist.

The upper ridge will expand to the east on Wednesday while a
weak back door cold front drops in from the north. Despite a
weak northerly surface flow developing, downslope component
aloft and large-scale warm air advection should result in warm
temperatures in the mid/upper 80s.

The upper ridge will hang on into Thursday though some
shortwave energy lifting out of the central gulf will yield
increasing isentropic ascent across the stalled front. Scattered
showers will be possible over the central and southern areas,
with thunderstorms possible farther to the south where a bit
more surface-based instability develops.

Long term /Thursday night through Monday/
The stalled front across ga is expected to shift north as a
warm front Thursday night into Friday followed by a cold frontal
passage Saturday. Drier high pressure looks to then return
later in the weekend before more unsettled weather possibly
moves back into the area for next Monday. Showers and
thunderstorms will be possible through Friday night, although
the best chances and heaviest amounts are likely through Friday
morning. Temperatures should remain above normal through the
period.

Aviation /00z Tuesday through Saturday/
Vfr conditions are expected to prevail through 00z Wednesday. We
will likely see isolated showers develop after midnight tonight
and approach kchs. Chances of direct impacts are too low to
include in the forecast. Fog/stratus concerns are low tonight.

Then for Tuesday, another round of mainly isolated showers and
thunderstorms. No direct impacts expected at the terminals, but
if there is a chance it would be highest at kchs.

Extended aviation outlook: low ceilings possible Wed night
through Thu night as a front stalls over the area. Brief flight
restrictions possible in showers and tstms Thu night through fri
night.

Marine
Tonight: southerly flow regime will persist overnight the area
will remain situated between high pressure well offshore and a
cold front to the west. Speeds will remain 10 kt or less with
seas 2-4 ft nearshore waters and 4-5 ft georgia offshore waters.

Tuesday through Saturday: strengthening east to southeast flow
Thursday into Friday will result in increasing seas, with 6
footers reaching the gulf stream by Thursday night. At least 6
ft seas expected over all coastal marine zones on Friday,
gradually subsiding Friday night into Saturday as the surface
high shifts east. Small craft advisories appear likely for much
of the area during this time.

Rip currents: 3 ft 10 sec swell, increasing onshore winds and
astronomical influences will yield a high risk for rip currents
along the sc coast and moderate for ga on Tuesday. The swell
will be decreasing on Wednesday though the risk will likely
remain elevated at least until then.

Tides/coastal flooding
High tides could reach advisory levels, mainly late
Wednesday/Thursday, due to strengthening onshore winds and
swells impacting the coast. This could cause shallow saltwater
inundation in typically vulnerable coastal areas, especially in
sc.

Chs watches/warnings/advisories
Ga... None.

Tuesday evening for scz048>051.
