Area Forecast Discussion
National Weather Service Charleston SC
1201 PM EDT Wed May 17 2023

.SYNOPSIS...
A cold front will move through the region tonight as high
pressure builds south into the Southeast. The high will weaken
through the weekend as another cold front approaches.

&&

.NEAR TERM /THROUGH TONIGHT/...
The overall flavor of the forecast looks on track. Activity
still looks like it will initiate over the Charleston Tri-County
with the focus shifting into Southeast Georgia this evening.
Near term pops were adjusted slightly for the noon update, but
nothing substantial. An increase in pops over Southeast Georgia
may be needed with the mid-afternoon package.

Today: A complex convective pattern is expected over the next
12-18 hours. The day is starting out rather warm with GOES-E
visible data showing strong insolation is occurring in many
areas. 17/13z temperatures were already running 1-4 degrees
warmer than this time yesterday owing to a slightly warmer
overnight period.

There is a bit of uncertainty on how convection will evolve
today. Much of the morning should remain dry with convective
temperatures holding in the mid-upper 80s. Expect pockets of
convection to initiate by mid afternoon as convective
temperatures are breached and gradually move south and expand in
coverage as the afternoon progresses. The latest short-term
CAMs suggest the best chances for showers/tstms will first start
out across the Charleston Tri County area as a lobe of
channeled vorticity passes by to the north, then gradually
expand south through the late afternoon across the rest of
Southeast South Carolina and Southeast Georgia along/ahead of a
very slow inland moving sea breeze boundary and along residual
convective outflows left over from yesterday evening's activity.
Convection may then culminate over Southeast Georgia into far
southern South Carolina this evening and into the overnight as
activity expands in response to an approaching shortwave moving
across the northern Gulf of Mexico. Pops were adjusted slightly
to delay the onset of highest rain chances into the evening
hours and to lower them slightly across the far north this
evening as the best focus shifts south.

Highs will warm upper 80s/near 90. Modified soundings support
around 1500 J/kg of mixed-layer CAPE with pockets of higher
values nearing 2000 J/kg. This will be more than sufficient to
support deep convection, especially as forcing increases with
the initial passing of a lobe of channeled vorticity this
afternoon across the northern and tonight as the shortwave over
the Gulf of Mexico draws closer. A few marginally severe tstms
will be possible with damaging winds and large hail being
possible, especially where updrafts can be enhanced near
mesoscale boundary collisions. Locally heavy rainfall could
occur and potentially cause some minor flooding issues, but
PWATs look to be running a bit too low for very intense hourly
rainfall rates.

Tonight: The cold front will slide south across the forecast
area, clearing all but maybe far southern sections by 6 AM
Thursday. This transition occurs with a wave of low pressure on
the front over the nearby Atlantic, with again a continuation
of low and mid level impulses moving through from west to east.
Any risk for severe weather will end early on with decreasing
CAPE and instability. We maintain PoPs as great as 60-80% early
on, diminishing somewhat with the passage of the cold front
thereafter.

A concern across the local counties late today into tonight,
mainly between 4 PM and 12 AM will be the risk for locally heavy
rains, where we are currently forecasting as much as 1 to 2
inches of rainfall. However, the HREF does have low end
probabilities of higher amounts given the elevated PWat and the
nearby cold front. Although the steering flow is a good 15 kt or
more, back building and/or training could occur with the
steering flow parallel to the orientation of the cold front.

There is certainly a chance for Flood Advisories, especially in
urban and poor drainage locations. In addition, some of the
heavier rains could occur around the time of the 7-8 PM high
tide, which would further aggravate the situation.

Stratus build down in likely to occur overnight, perhaps leading
to the formation of fog. We'll leave this to later shifts to see
if fog should be included in the forecast.

As winds shift to the north and northeast behind the cold front
it'll allow for some cooler air to move in. As cold air damming
begins to establish itself, lows will drop down to the mid and
upper 60s, with a few lower 60s in Berkeley County.

&&

.SHORT TERM /THURSDAY THROUGH SATURDAY/...
Thursday and Friday: Surface high pressure across the Northeast will
begin to build south where a cold air damming pattern is expected to
set up across the Mid-Atlantic, stretching across the Carolinas into
Georgia. The cold front will be positioned across the SC/GA border
where an area of low pressure is expected to form. The low will
slowly drift offshore, becoming nearly stationary over the Gulf
Stream Thursday afternoon. Deep moisture will continue to advect
across the region via return flow/wrap around moisture from the
offshore low. This will result in scattered to possibly numerous
showers and isolated thunderstorms. Instability is limited across
the area, considering there will not much of a break in clouds and
very little rebound in terms of diurnal heating. Rainfall amounts of
around 0.5 to 1.0 inch are expected through Thursday night, with the
exception of the South Carolina coastal communities where localized
areas could receive 1.5 to 2 inches. Additionally, surface winds
will increase rapidly due to the development of the
CAD/strengthening of the pressure gradient. Winds will be gusty
along the beaches Thursday as well as across Lake Moultrie. A Lake
Wind Advisory for Lake Moultrie at this juncture does not look
likely, although there could be periods of brief 25 kt gusts.
The area of low pressure will finally lift north toward the Outer
Banks Friday, with deep wrap-around moisture gradually decreasing.
Meanwhile, the surface wedge will begin to erode ahead of a strong
cold front pushing across the Central U.S. Isolated showers will
linger along the coastal areas Friday morning while shortwave energy
moves overhead bringing weak forcing for ascent. Showers could then
spread inland as a weak sea breeze develops once some clearing of
clouds is able to occur and temperatures warm.

High temperatures will be tricky to forecast due to the CAD in
combination with deep moisture and evaporative cooling from any
rains. For now we have high temperatures Thursday in the low 70s
across interior South Carolina, and mid 70s along the coast and
across southeast Georgia where warmer onshore flow will mitigate any
cooling. Low temperatures could dip into the upper 50s across
interior South Carolina, but most areas will see min temps in the
low/mid 60s. Highs will be a few degrees warmer for Friday, topping
out in the upper 70s to low 80s. Lows will sit in the low to mid 60s.

Saturday: Weak surface high pressure will remain in place, while a
cold front approaches from the northwest. Forcing ahead of the front
associated with a potent shortwave will result in scattered showers
and thunderstorms Saturday, mainly in the afternoon, in combination
with the development of a sea breeze. Temperatures will top out in
the mid 80s ahead of convection.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
A deep mid/upper level low traversing the northern Great Lakes looks
to push a cold front across the area late Saturday into Sunday.
Models hint toward a potent shortwave breaking off from the main
energy to the north and forming possibly a closed mid-level low
across the Carolinas. This will continue the active pattern into
Sunday as large scale forcing takes precedence. Another cold air
damming wedge pattern could set up Monday night into at least the
middle of next week. This should keep the majority of the area rain
free as the wedge keeps dry air in place with rain chances staying
mainly south of the forecast area. Temperatures will be fairly
consistent through the long-term forecast period with highs in the
low to mid 80s and min temps in the low to mid 60s.

&&

.AVIATION /16Z WEDNESDAY THROUGH SUNDAY/...
17/18z TAF discussion:
KCHS/KJZI: Initial convective focus will be centered near both
KCHS and KJZI through mid-afternoon as weak shortwave energy
passes to the north. VCTS was maintained 21-00z as the core of
the activity looks to pass just north of the terminals.
Amendments may be needed as trends dictate. Activity should end
by late afternoon with the focus shifting south. A round of
showers and embedded tstms will approach from the southwest
overnight. There is still some uncertainty on widespread this
activity will be when it reaches this far north and the backdoor
cold front drops through the terminals. A TEMPO group for MVFR
vsbys in -RA was included 7-10z to trend. In addition, IFR cigs
will spread in after 07z behind the backdoor front with more
widespread low cigs holding from 10-18z as an area of showers
impacts the region. Cigs were held just above alternate minimums
for now.

KSAV: Most of the afternoon looks to remain rain-free. The risk
for showers/tstms will increase substantially after 00z as a
band of convective approaches from the south/southwest. The risk
for tstm impacts looks greatest roughly 02-05z with the passage
of this band. VCTS with a TEMPO for 3SM TSRA was used to address
this potential, but lower conditions may be needed as radar
trends become more apparent. Some degree of light shower
activity may linger through about 06z, but MVFR cigs will spread
in from the north with the passage of the backdoor cold front.
THere is a risk for prevailing IFR cigs after 11z, but limited
cigs to low-end MVFR for now as there is still some uncertainty
on exactly how low cigs will get this far to the south.

Extended Aviation Outlook: There will likely be reduced vsbys and
cigs in showers/tstms Thursday. Gusty winds are likely at the
terminals Thursday and Thursday night due to a southward building
wedge of high pressure. Gusts up to 25-30 kt are expected at KCHS
and KJZI, while gusts at KSAV will top out around 20 kt.
Additionally, showers/tstms this weekend could bring brief flight
restrictions during the afternoon and evening hours.

&&

.MARINE...
17/06z HREF now showing a >70% for sustained 30 kt winds in the
South Santee-Edisto Beach nearshore leg. A Gale Watch has been
posted for this area from late tonight through Thursday evening.

Today: A broad trough across the waters will give way to an
approaching cold front late day. W winds early on will back to
the SW and S for the afternoon with sea breeze influences, with
speeds generally 15 kt or less. Seas will average 2-4 feet.

Tonight: The cold front slides south through most of the waters,
as a wave of low pressure forms along the front. Inland we start
to see the formation of a high pressure wedge, leading to a
packing of the pressure gradient on the Charleston County
waters late. Winds will shift to the NE on these waters, and
winds will be near or above advisory levels on the AMZ330 and
AMZ354 waters by daybreak. Winds are still below advisory
thresholds on the other waters through the night. We'll have
some 5 foot seas on the northern most AMZ350 waters late, with 3
feet or less elsewhere.

Mariners can anticipate clusters of showers and t-storms late
today into tonight, a few of which could be strong or marginally
severe. Special Marine Warnings and/or Marine Weather Statements
could be required.

Thursday: The resulting tightening of the pressure gradient in the
wake of a southward moving wedge and developing low pressure
offshore will support solid northeast winds of 20-30 kt with a
potential for frequent gusts to 35 kt. Small Craft Advisories have
been issued for the Charleston Harbor and the southeast South
Carolina nearshore waters out 20 nm starting just after daybreak
Thursday, with the exception of the Charleston County nearshore
waters which starts a few hours before daybreak. The potential for
frequent gusts to gales continues to increase across the Charleston
County nearshore waters Thursday afternoon/evening and a Gale
Watch/Warning could eventually be needed. Seas will build 4-9 ft,
highest over the South Santee-Edisto beach nearshore leg. Conditions
across the Georgia waters from 0-60 nm will be much more tame with a
brief period of 6 foot seas and 25 kt wind gusts starting Thursday
evening, which could warrant Small Craft Advisories for those zones
as well.

Friday through Monday: Conditions will improve on Friday as the CAD
breaks down and low pressure offshore of the Southeast U.S. coast
pushes farther north. A cold front is expected to push across the
local waters Sunday bringing a slight surge in winds Monday,
however, there are no marine concerns at this time.

Rip Currents: There will be an enhanced risk for rip currents
Thursday into Friday as gusty northeast winds develop along the
beaches. A High Risk for Rip currents is in place for all Southeast
South Carolina beaches Thursday and a Moderate Risk for the Georgia
beaches.

&&

.TIDES/COASTAL FLOODING...
With the approaching New Moon on Friday, astronomical tide
values will be elevated this week. Tide values may reach or
exceed 7.0 ft MLLW along the Charleston and Coastal Colleton
coastlines with the evening high tides both today and Thursday.
The greatest chance of coastal flooding is with the Thursday
evening high tide as winds shift to the northeast. Coastal
Flood Advisories will likely be required.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...None.
SC...None.
MARINE...Small Craft Advisory from 8 AM Thursday to 4 AM EDT Friday for
     AMZ330.
     Gale Watch from late tonight through Thursday evening for
     AMZ350.
     Small Craft Advisory from 11 AM Thursday to 10 AM EDT Friday
     for AMZ352.
