Area Forecast Discussion
National Weather Service Charleston SC
438 PM EDT Mon Apr 23 2018

.SYNOPSIS...
Low pressure will shift over the area tonight, then slowly move
up the east coast through mid week. An upper disturbance will
move over the area Thursday night, followed by a cold front late
week. High pressure will return over the weekend.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Rest of the afternoon/evening: A swath of moderate to heavy
rain continues to stream across the the coastal waters and
onshore into Charleston County and further inland. Based on the
reflectivity that is sitting just offshore right now, there will
be an enhancement in the rainfall rates over the next couple of
hours. This should push rainfall amounts in this area into the
2+ inch range, with some isolated amounts around 3 inches.
Overall, the severe threat is quite low due to the lack of
instability rooted in the surface. There is enough instability
just off the surface to generate some rotating storms over the
coastal waters, but these have been weakening as they reach
shore. The veering profiles and strong low level flow will
continue to produce this type of storm structure on the cool
side of the warm front situated to the south. Have removed the
severe wording from the Hazardous Weather Outlook due to this
lack of instability.

Tonight: The deep upper low and attending surface low centered
over Tennessee will slowly lift to the northeast. As this
occurs, a warm front will lift northward through the forecast
area, and the deep moisture will begin to strip out aloft.
Precipitation will come to an end from southwest to northeast
steadily through the night. By sunrise, only isolated to
scattered showers are expected to be lingering in the Tri-County
region. Skies will remain overcast for most of the night,
though portions of southeast Georgia could start to scatter out
late. It will be a mild night with lows only falling into the
low to mid 60s. Winds will remain strong and gusty into the
Charleston County area through the evening, weakening through
the overnight.

Lake Winds: Winds will remain gusty across Lake Moultrie and it
south and southeast facing shores. The Lake Wind Advisory
continues through 8 pm.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
Tuesday: A cold front will be offshore by daybreak, shifting
northeast and further offshore while an area of sfc low pressure
tracks along/near the Mid-Atlantic coast. A trailing mid/upper
lvl low to the west/northwest will slowly meander over the
Southeast during the day, then shift over the Mid-Atlantic
states late day and night. The overall pattern suggests mostly
dry conditions and less cloud cover. However, a few showers can
not be ruled out across northern and inland areas in Southeast
South Carolina, as the mid/upper lvl low shifts just north of
the area. Overall highs will be slightly warmer, peaking in the
upper 70s under partly cloudy skies. Overnight lows will be
fairly mild, ranging in the mid/upper 50s away from the
immediate coast.

Wednesday: The main mid/upper lvl low will continue to shift
east- northeast and away from the area, setting up dry
conditions and mostly sunny skies as high pressure temporarily
shifts into the region and a downsloping wind component occurs
over the Southeast. Overall highs should be a degree of two
warmer than the previous day with more sun. In general, highs
should peak in the upper 70s to around 80, warmest along and
east of the I-95 corridor. Temps will remain mild overnight,
ranging in the mid/upper 50s away from the immediate coast.

Thursday: The next best chance of rainfall should occur with a
low pressure system that quickly advances over the Deep South
and to the Southeast United States. Latest trends suggest much
of the area will remain dry during daylight hours until the bulk
of strongest forcing arrives with an h5 shortwave aloft late
day and overnight. Chances of showers have been limited to
inland areas through the afternoon, before precip activity
increases during the evening and overnight. Increasing clouds
and showers late in the day could limit overall heating
potential. In general, high temps should approach the mid/upper
70s, warmest in Southeast Georgia.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Forecast confidence in the extended period continues to be low
given large spread in model guidance. General consensus is that
a cold front will cross the area late week/early weekend. Given
the uncertainty on details, have kept PoPs pretty low until
trends become clearer. Models come into better agreement on
Sunday with a return to high pressure. Temperatures through the
period will generally be near normal, perhaps slightly cooler on
Saturday.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
KCHS: The main feed of deep moisture and moderate to heavy rain
will continue to feed into the terminal for the next few hours.
Visibilities will be in the MVFR range, but ceilings will be
IFR. These conditions will last into the evening, though
ceilings may be variable and lift into the MVFR range later this
afternoon. Winds will remain ESE and gusty into the 30 knot
range. Overnight, showers will come to an end and model guidance
strongly suggest that a period of IFR ceilings will develop.
Have timed the ceilings in starting at 02z, with improvement by
13z. There could be a rumble or two of thunder this afternoon,
but chances are too low to mention in the forecast.

KSAV: Newly developed showers and isolated thunderstorms are
approaching the terminal from the southwest and will likely
impact through about 20z. IFR ceilings will likely stick around
through this time. Wasn't confident enough that there will be
thunder so it is not mentioned in the forecast. Thereafter,
showers will be more scattered in coverage and the main forecast
issue then becomes the potential for IFR stratus overnight.
Have timed it into the terminal at 04z, with improvement by 11z.

Extended Aviation Outlook: Flight restrictions are possible
with showers late Thursday/early Friday.

&&

.MARINE...
Tonight: Conditions across the South Carolina waters are likely
at their worst now through the late afternoon hours.
Observations along the Charleston County coast indicate frequent
gusts to around 30 knots, and 41004 is continuing to gust into
the 35-40 knot range. The Gale Warning for the Charleston County
waters is therefore likely working out just fine with frequent
gusts into the 35 knot range. The warning remains in effect
through 2 am. Elsewhere, at least solid Small Craft Advisory
conditions are ongoing and the advisories remain in effect. Seas
are quite impressive, with 41004 reporting 13 feet and 41008
reporting 7 feet. Once a warm front lifts northward through the
area this evening, conditions will begin to improve as the
gradient relaxes and winds subside. Heavy rain will continue to
reduce visibilities across the Charleston Harbor and the
Charleston coastal waters through the evening, with improving
conditions thereafter.

Rip Currents: The High Risk of rip currents continues through
this evening for the Charleston County coast.

High Surf: The High Surf Advisory continues for the Charleston
County coast through the early morning hours. Winds are now
strongest along the coast with gusts into the low 30 knot range.
Conditions will improve late tonight.

Tuesday through Saturday: Marine conditions will improve
Tuesday as a cold front and low pressure lift northeast and away
from the area. Small Craft Advisories will gradually drop as
seas fall below 6 ft, first in the southern nearshore Georgia
waters late Tuesday morning, then nearshore South Carolina
waters south of Edisto, SC early Tuesday afternoon. Higher seas
will linger in northern SC waters and offshore Georgia waters
through Tuesday night and potentially into early Wednesday
morning. Low confidence remains in the forecast late week given
model discrepancies, but it appears conditions will remain below
any headline criteria. A cold front could drop through the
waters early in the weekend, then high pressure will return for
the remainder of the weekend.
