Area Forecast Discussion
National Weather Service Charleston SC
1253 AM EST Thu Dec 20 2018

.SYNOPSIS...
A strong storm system will bring multiple impacts to our area
tonight into Friday. High pressure is forecast to return this
weekend and persist through early next week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
No significant changes for the midnight update. Tweaks on temps
in some areas, timing for the onset of rain mainly unchanged.

Inland high pressure will hold firm as low-level jetting begins
to strengthen across the Southeast U.S. ahead a phased longwave
trough extending north to south across the central states.
Isentropic assent will rapidly intensity after midnight with
moisture gradually working from the top down reaching near
saturation for most areas by daybreak. Expect a good portion of
the forecast area will be seeing rain by sunrise Thursday and
pops reflect this trend with going to 90-100% by 20/12z. Lows
from the upper 40s inland to the mid 50s at the beaches look on
track.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH SATURDAY/...
Thursday: The mid-levels will consists of a trough axis stretching
along the MS Valley in the morning. The trough will shift eastward
and continue to amplify as time progresses. A weak low may develop
at the base of the trough, roughly over the Southeast overnight. At
the surface, a storm system will be developing to our southwest in
the morning. Low pressure initially over or near the FL Panhandle in
the morning will move northeastward and split into two separate lows.
One will be located just to our west late at night while the other
will be located/developing over the Eastern Great Lakes region. A
complex series of fronts will be associated with these lows. Plenty
of moisture will be across our area. Models still hint at PWATs
peaking ~1.75", which is 2-3 standard deviations above normal per
NAEFS. With good moisture and lift in place, POPs are at 100%.
Moderate rain is expected during the daylight hours. Most locations
should expect 1.5-2.0" of rain through Thursday night. Though,
locally some >2" amounts are possible, especially across the
Charleston Tri- County area. Precipitation will begin to taper
off in the evening, with remnant showers persisting overnight.
Temperatures will remain a few degrees above normal within the
warm air mass.

Tides: Moderate rainfall with the Thursday morning and afternoon
high tides could cause drainage issues. However, the strongest
onshore winds in the afternoon are expected to be with the lower of
the two high tides, limiting the potential for flooding from
saltwater inundation. Winds parallel the coast with the daybreak
Friday high tide, so it's still too early to determine the flood
potential with that tide.

Friday: The mid-levels will consist of a strong trough stretching
from the Great Lakes region into the Southeast during the morning
hours. The trough will move eastward with time and become negatively
tilted. At the surface, the strongest portion of the storm system
will be far to our northeast. However, the second low initially to
our west early in the morning will quickly move to the northeast
with time. Gulf Coast high pressure will begin building into the
Southeast overnight. Wrap around precipitation associated with the
departing low should gradually wind down during the daytime. QPF
shouldn't add up to much. Dry conditions should prevail overnight.
Temperatures will be near normal.

Winds: Southwest winds should be gusty in the afternoon, especially
along the coast. A wind advisory may be needed, especially for the
Charleston County coastline. Impacts may be more noticeable with the
saturated ground. Winds will increase over Lake Moultrie Friday
and could reach Lake Wind Advisory criteria with 25 knot gusts.

Saturday: The mid-levels will consist of a negatively tilted trough
moving off the coast, allowing zonal flow to develop over the
Southeast into the afternoon. At the surface, broad high pressure
initially over the northeastern Gulf of Mexico will move towards the
Southeastern U.S. Dry conditions will prevail. Temperatures may
be a few degrees below normal.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Cooler and dry conditions expected to prevail this period with high
pressure generally dominating. Temperatures should be near to above
normal.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
VFR conditions will steadily deteriorate closer to daybreak and
continue through the day as widespread rains impact the region.
Expect widespread IFR vsbys and MVFR Cigs to prevail after
sunrise with gusty winds impacting both terminals. Gusts in
excess of 25 kts are possible. There is a potential for low-
level wind shear during the afternoon, but the situation looks
to marginal to include a mention for the 06z TAF cycle. Chances
for showers will extend into the evening but rains should be
lighter. MVFR/IFR cigs remain possible.

Extended Aviation Outlook: A storm system will bring flight
restrictions late Thursday through Friday. Gusty winds likely late
Thursday through Friday night. VFR Saturday through Monday.

&&

.MARINE...
Tonight: Fairly weak winds expected this evening, then rapidly
strengthening SE winds late tonight as surface low pressure
moves into south central GA. Winds and seas expected to be just
shy of Small Craft Advisory criteria in the GA waters around
daybreak Thursday.

Thursday through Monday: Both the NAM and GFS wind have
increased across the Charleston County waters to justify a Gale
Watch. Interestingly, the GFS shows several 50 kt wind barbs
over the Georgia offshore waters closer to the Gulf Stream.
Unclear if this will occur or not, but a nasty wind signature in
noted in both the GFS and NAM.

A storm system will bring impacts to our area Thursday into
Friday, causing high winds and seas. Models indicate a short
window of Gale Conditions are possible for the GA waters beyond
20 nm Thursday afternoon into evening. For simplicity with the
marine headlines, we opted to only go with a Gale Watch with
this zone. For all of the remaining waters within 20 nm, we have
Small Craft Advisories for winds and seas starting Thursday. A
second surge of winds/seas is expected Friday morning into
evening for all of the coastal waters. Gale conditions seem
likely, but it's still too early to issue Gale Watches to cover
this time period. Very steep wind- driven seas could peak above
10 ft beyond 10 nm and around 15 ft across the outermost portion
of the outer GA waters. Additionally, the Charleston Harbor
will have periods of at least Small Craft Advisory wind gusts
Thursday evening into Friday. However, there is still enough
uncertainty in the start time to warrant holding off on an
advisory at this time. Winds and seas will trend downward Friday
night into Saturday as the storm system moves away.

&&

.HYDROLOGY...
High resolution guidance is coming into better agreement that a
period of heavy rain will impact mainly Southeast South Carolina
Thursday afternoon through mid-evening, clearing the Charleston
Tri-County area last. Both the RAP and H3R show what appears to
be a nasty line of highly forced convection moving northeast
across the Charleston Tri-County mid-late afternoon as high tide
is peaking. Although tides are expected to remain well below
advisory thresholds, heavy rains falling a few hours either side
of high tide usually causes problems, especially in wet regimes
such as the one the region is currently in. CPC soil mositure
analysis shows soil moisture values are running roughly 600% of
normal for this time of year across the quad-county area. 1-hr
and 3-hr flash flood guidance values are as low as 2.2 inches in
places, which could be easily overcome in pockets of heavier
rainfall. A Flash Flood Watch has been issued for Charleston,
Berkeley, Dorchester and Colleton Counties for Thursday from
noon until 11 PM EST.

&&

.TIDES/COASTAL FLOODING...
Tides/Coastal Flooding...Tides will be on the increase late this
week due to a full moon and strong onshore winds, possibly reaching
marginal Coastal Flood Advisory levels around Charleston during the
Thursday morning, Thursday evening and/or Friday morning high
tides.
