Area Forecast Discussion
National Weather Service Charleston SC
1124 AM EDT Sat Apr 24 2021
.SYNOPSIS...
A storm system will impact the region through tonight. High
pressure will prevail most of next week, followed by a cold
front late in the week.
&&
.NEAR TERM /THROUGH TONIGHT/...
After coordination/collaboration with SPC, we opted to raise a
Tornado Watch valid through 6 pm today. This is in response to
the QLCS that is starting to impinge on our west and southwest
Georgia counties as of late morning. While there has been
nothing more than some elevated instability over or near our
forecast area, more surface-based instability, more of that is
forecast to develop this afternoon, especially over Georgia to
the south of I-16. Latest guidance shows MLCAPE reaching as much
as 500 J/kg across these regions. Meanwhile, shear and
helicity are quite impressive, showing 0-1 km values as high as
30-40 kt and 250-350 m2/sec2, respectively.
The air mass across our region is a bit drier than further
southwest, but based on the strength of the shear and the
proximity to a warm front that will lie nearby, this will likely
compensate for the lack of significant instability.
We are basing our forecast heavily on the HRRR solution which
shows the QLCS racing quickly eastward, and moving off our
Georgia coastal corridor by early to mid afternoon. Not yet
certain on how far north the potential exists for severe weather
into South Carolina, but where the line does move through there
does remain a risk for damaging winds, large hail and isolated
tornadoes.
The unknown is how much recovery will occur behind this initial
round of convection and will the resulting instability be at a
point to support a well-defined squall line in the presence of a
strong wind field. It could very well be a scenario where
recovery is not enough to overcome the strong kinematics in
place and weak convective updrafts just get sheared apart.
However, if any stronger instability can redevelop, conditions
would certainly favor a second squall line with embedded
supercells and/or "broken-S" features further north and in wake
of this first round.
While the QLCS could produce heavy rains with hourly totals of
1" or more, the greatest concerns for potential flash flooding
will be on the trailing southwest portion of the QLCS that will
not be as progressive and has the potential for training of
cells in a more west to east direction, which will become more
aligned with the steering flow. These areas will likely see the
best potential for west to east training of cells in an axis of
PWat values of 2 to 3 standard deviations above the mean. HREF
probabilities are 60-90% for 2" or more totals, 40-70% for 3" or
more totals, and even as high as and 20-40% for 5" or more
totals across this area where training occurs. Our latest QPF
shows 1.5 to 3" amounts to occur, but locally higher amounts can
be expected as per the HREF guidance.
Various guidance continues to depict a few hours of wind gusts
as high as 30-35 knots through about 3 or 4 PM. Given the
amount of convection and cloud cover, this seems unlikely. But
should any breaks temporarily occur, it is conceivable that
winds could achieve 35-45 mph at times, even in the absence of
convection. We still feel best not raising a Wind Advisory nor a
Lake Wind Advisory on Lake Moultrie however.
We applied minor tweaks to temperatures, both on the hourly
scale and regarding maximum values.
Previous discussion...
No major changes were made for the sunrise update. H3R has
slowed the progression of the QLCS moving across southern
Alabama by about an hour.
A potent southern stream shortwave ejecting out of the Southern
Plains will quickly propagate east today, reaching the southern
Appalachians by sunset. Its surface reflection in the form of a
large, baggy surface cyclone will move steadily east out of the
Lower Mississippi Valley and across the Deep South through the
day. An ill-defined warm front currently sharpening up across
the southern portions of Mississippi, Alabama and the Florida
Panhandle early this morning will move north as the low moves
east aided by a strengthening low-level jet across the Southeast
States. It is not exactly certain where the warm front will set
up, but current high-res guidance suggest it will move just
north of the local area with much of Southeast South Carolina
and Southeast Georgia becoming embedded with in the warm sector.
Expect widespread showers/tstms, possibly in the form of
several waves or convective clusters, to encompass much of
Southeast South Carolina and Southeast Georgia later this
morning and persist into this evening as low-level wind fields
increase ahead the approaching surface low and trailing cold
front. This activity will be mainly driven by strong forcing
for ascent juxtaposed within a tongue of deep-layered moisture
advecting north/northeast out of the Gulf of Mexico. Pops have
been increased to 100% through this evening to account for the
high likelihood of the region finally seeing some much needed
rainfall. While rain will bring some relief to the ongoing dry
spell noted throughout much of April, there are several hazards
poised to potentially impact the region over the next 12-18
hours.
Severe Weather: The various models have been struggling on how
to resolve today's convection for over a week. This morning's
near term guidance, although coming into some agreement, is
still showing a number of possible outcomes on how the severe
risk will unfold. There are still a lot of unknowns, but the
general consensus favors a potential for at least two rounds of
severe weather through this evening...
1. The first could come in the form of a QLCS moving west-east
across mainly Southeast Georgia into far southern South Carolina
from late morning into the mid afternoon as the warm front
moves north. This scenario has been depicted by the H3R for the
past several runs and has some support from the RAP and HWR-
ARW. While significant surface-based instability will likely be
lacking during this time, RAP soundings do suggest there will be
enough in the presence of region of increased forcing and
strengthening low-level wind fields to support such as feature.
If this QLCS develops, the primary hazard would be damaging
winds with a risk for an isolated tornado, especially near any
book-end vortex, a "broken-S" or where the convective line
intersects the warm front.
2. The second could come as a much stronger squall line moving
east/southeast out of central Georgia and across much of
Southeast Georgia into the far southern portions of southern
South Carolina during the diurnal maximum into the evening hours.
The unknown here is how much recovery will occur behind
possible morning convection and will the resulting instability
be at a point to support a well-defined squall line in the
presence of a strong wind field. It could very well be a
scenario where recovery is not enough to overcome the strong
kinematics in place and weak convective updrafts just get
sheared apart. However, if stronger instability can redevelop,
conditions would certainly favor a severe squall line with
embedded supercells and/or "broken-S" features. Current data
suggest there will be sufficient recovery, but there is plenty
that could go wrong. 24/06z SPC guidance depicts a 30% chance
for damaging winds and a 10% chance for tornadoes for Southeast
Georgia into far southern South Carolina, which aligns with an
"enhanced risk." This guidance seems reasonable at this time,
again assuming morning convection does not linger. In addition
to damaging winds and tornadoes, there will be a risk for large
hail as more intense drafts could promote hail formation. The
severe potential becomes much more conditional north of a
Hiltonia- Beaufort line where the risk for recovery this
afternoon will be much more limited. This includes the
Charleston Metro Area.
Heavy Rainfall/Flooding: There will be a risk for heavy rainfall
and at least a low-end threat for flooding this afternoon into
tonight. Model cross-sections show a corridor of intense, deep-
layered omega becoming aligned with a nearly saturated column
from 25 kft down to the surface. As PWATS climb to near 1.75"
and convection becomes more intense with time, pockets of heavy
rainfall appear likely with 1-hour rainfall rates potentially
becoming excessive. A widespread swath of 1-3 inches of rain
with locally higher amounts is expected through this evening
with the higher amounts occurring over Southeast Georgia,
including the Savannah Metro Area. While the recent dry weather
will likely limit widespread flash flooding, minor flooding of
low-lying, poor drainage, and urban areas is possible.
Complicating matters is heavy rain could be ongoing as the
elevated evening high tide approaches. This could increase the
risk for more significant flooding, especially in both Downtown
Charleston and Savannah, so this will have to be watched
carefully. The latest HREF show probabilities of >3" averaging
about 20-30% across much of Southeast Georgia. Per coordination
with the WPC Day-1 QPF desk, a "slight risk" for excessive
rainfall has been introduced for much of Southeast Georgia.
Finally, the daily rainfall records for all three climate sites
could be challenged today, although Downtown Charleston's (KCXM)
record of 3.06" set in 2017 could be a toughest one to break.
See the climate section below for details.
Non-Convective Winds: There is a potential for windy conditions
to develop today as strong low-level wind fields settle over
the region. Current thinking is there will be enough convection
and cloud cover to prevent significant momentum transfer of
these winds to the surface outside of convection. Interestingly,
the localized aviation MOS (LAV) has been highlighting about
3-hr period of wind gusts 30-37 kt in the coastal corridor
between 17-20z from Savannah to Charleston since yesterday
evening. While this could be convectively induced, it bears
watching as any clearing that occurs could easily produce wind
gusts 50-55 mph outside of showers/tstms. There are no plans to
hoist a Wind Advisory or Lake Wind Advisory for Lake Moultrie at
this time. This will be reevaluated later today as temperature,
sky and convective trends become more apparent.
&&
.SHORT TERM /SUNDAY THROUGH TUESDAY/...
A mid-level trough will quickly move off the East Coast Sunday
morning, followed by a strengthening ridge moving over the Eastern
Seaboard by late Monday. Likewise at the surface, a front will be
located off our coast Sunday morning, quickly moving away. Broad
high pressure located over the Great Lakes region at that time will
move southeast, becoming centered just along or off the Southeast
Coast by Monday night. Plenty of dry air will lead to sunny/clear
skies both days/nights. Temperatures should be within a few degrees
of normal.
&&
.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
The WPC is forecasting high pressure just off the Southeast coast
Tuesday and Wednesday. It'll move offshore Thursday while a distant
cold front approaches from the west into Friday. The NBM has dry
conditions with a gradual warming trend through Thursday. It has
increasing POPs late Thursday into Friday, ahead of the front.
&&
.AVIATION /15Z SATURDAY THROUGH WEDNESDAY/...
Previous thinking from the 06z TAF cycle still applies for 12z
with a few minor timing adjustments. Conditions will
deteriorate by mid-morning as a storm system approaches from the
west. An initial band of showers/tstms is expected to reach
KSAV by around 17z and KCHS about 1-2 hours after that. This
activity will mark the beginning of lowering vsbys and cigs at
both terminals. Tstm impacts are likely with a longer duration
of tstms possible at KSAV. There are indications that a squall-
line type feature will move through KSAV by late morning,
potentially bringing a brief period heavy rain and gusty winds
as high as 35 kt. Will handle this will a TEMPO roughly 18-20z.
Tstms appear less likely at KCHS given less instability, but a
mention will be included in a TEMPO 18-21z. Surface winds should
remain elevated enough to preclude non- convective low-level
wind shear. Shower/Tstms should exit the area by mid-evening as
a cold front approaches.
Extended Aviation Outlook: VFR.
&&
.MARINE...
Today: Winds will increase across the waters today as a warm
front lifts north. Speeds will reach 15-20 kt with gusts to
25-30 kt all legs. Widespread convection should keep low-level
jetting influences limited, but convective gusts could reach
35-50 kt at times. Small Craft Advisories are in force for all
waters and Special Marine Warnings will likely be need later
today. There is a risk for damaging winds, waterspouts and large
hail with any tstms this afternoon. In addition, locally heavy
rainfall could reduce vsbys to 1 NM or less at times, mainly
this afternoon and evening.
Tonight: The risk for severe weather will end this evening.
Southwest winds will continue to gust 25-30 kt at times. A cold
front will approach the waters by sunrise Sunday.
Sunday and Monday: The remaining Small Craft Advisories should
expire by noon as seas subside. A cold front will be offshore Sunday
morning, quickly moving away from the area. At the same time, high
pressure initially centered over the Great Lakes Region will move
southeast, becoming located just off the Southeast coast by late
Monday. The high will cause winds to clock around with time while
remaining generally 10-15 kt or less.
Tuesday and Wednesday: The NBM and various wave models are
forecasting low winds and seas. No marine headlines are expected.
Rip Currents: Gusty wind onshore winds and building seas will
support a moderate risk for rip currents at all beaches today.

.TIDES/COASTAL FLOODING...
Tides could get high enough to cause minor saltwater inundation
around Charleston during the evening high tide Saturday. There
is also the potential for heavy rainfall during this time which
would exacerbate any flooding. Additional minor coastal flooding is
possible through early next week, especially with the evening high
tide along the southern SC coast due to the upcoming Perigean Spring
Tide cycle. Coastal Flood Advisories may eventually be needed.
