Area Forecast Discussion
National Weather Service Charleston SC
355 AM EST Mon Nov 30 2020

.SYNOPSIS...
A strong storm system will affect the region this morning. Cold
high pressure will slowly build in its wake and persist through
the rest of the week. A cold front will then push through the
area Friday.

&&

.NEAR TERM /THROUGH TONIGHT/...
Today: Radar indicates mostly dry conditions in SC to start
with moderate to occasionally heavy rainfall in GA.
Temperatures and dewpoints continue to increase behind the warm
front which passed through earlier in the night and is now
located near the NC/SC border. The main concern this morning
continues to be the risk for isolated severe storms as
instability increases slightly ahead of the approaching cold
front. SPC mesoanalysis shows 500+ J/kg of surface based CAPE
nearing inland GA as well as near the SC coast where values near
1000 J/kg are found. Meanwhile effective bulk shear is 60+ kt
for a good portion of the forecast area. Thus, we can't rule out
a few severe storms with damaging winds and/or a tornado.
Otherwise, southerly winds will be increasing as the pressure
gradient and mixing increase with gusts near 40 mph, especially
near the SC coast where a Wind Advisory is in effect. However,
will continue to monitor for a possible expansion of the
Advisory a bit farther inland as per high-res model wind gust
progs. Of course, wind gusts could easily surpass 40 mph
anywhere where there are heavier showers/storms. The rain should
push off the Charleston County coast by noon with cooler and
drier air moving in thereafter. Thus, high temperatures should
occur near daybreak and then generally fall through the day.

Tonight: The broad upper low/trough will shift toward the East
Coast as low-level high pressure builds from the southwest.
After a lull in winds early in the evening we should see another
surge overnight as much colder air moves into the area. Lows
should fall back to near freezing well inland and closer to 40
near the coast, although wind chills will likely make it feel
like the mid to upper 20s inland and near freezing even at the
coast. As a reminder, our local frost/freeze program ends today
(based on climatology) so we will not be issuing any Frost
Advisories or Freeze Warnings for tomorrow morning.

Lake Moultrie: A Lake Wind Advisory remains in effect for Lake
Moultrie into this afternoon for gusty southwest to west winds
up to 30 kt. We may need to extend the Advisory into tonight as
gusts could stay near 25 kt.

&&

.SHORT TERM /TUESDAY THROUGH THURSDAY/...
A dry and cold air mass will build in the wake of the front, with
the center of high pressure gradually shifting over the region by
Wednesday and prevailing through the period. Strong CAA will
continue through Tuesday as WNW winds at H85 remain elevated over a
sharp temperature gradient. Gusty winds over land will continue
through Tuesday and are expected to subside overnight. Highs will
only reach the upper 40s inland and near 50F along the coast. A hard
freeze is likely Tuesday night over the interior counties with low
temps dropping to the mid 20s inland and low 30s along the coast. A
gradual warming trend will occur over the next couple of days with
high temperatures in the mid 50s on Wednesday and low/mid 60s
Thursday, with min temps increasing gradually as well.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
High pressure will dominate the region through the week. This
weekend, expect a slight change in the overall pattern as the sfc
high moves offshore over the Central Atlantic and a deep upper-level
trough/H5 closed low located over the Tennessee Valley helps push a
cold front through the area Friday. In response to the upper-level
system, a sfc low eventually develops along the East Coast by
Saturday. There is somewhat large model discrepancy in terms of
where this system will spawn; however it is likely to develop to our
north. A system that forms offshore the Mid-Atlantic states, will
likely trend toward a drier forecast for our area; however, a system
developing offshore the Carolina Coast could in turn bring
sufficient moisture. That combined with upper-level forcing would
allow scattered showers to develop over the area Friday night into
Saturday. Thereafter, rain-free conditions are expected through the
remainder of the period as high pressure returns.

&&

.AVIATION /08Z MONDAY THROUGH FRIDAY/...
KCHS: Starting out VFR but expect deterioration to MVFR,
possibly even IFR, as a cold front brings showers and a few
thunderstorms to the region this morning. Mainly VFR again after
about 14Z although there will still be a low risk for MVFR
conditions through the rest of the 06Z/30 TAF period due to some
lingering low-level moisture.

KSAV: Starting out VFR until about 10Z when at least MVFR
conditions are expected in showers and possible storms. VFR
should return about 14Z, although there will still be a risk of
MVFR thereafter due to lingering low- level moisture.

Extended Aviation Outlook: VFR. Gusty winds will persist
through Tuesday evening.

&&

.MARINE...
Today/Tonight: Dangerous marine conditions expected much of the
period as a strong cold front moves through this morning
followed by strong cold advection. Gales are likely for all
waters into this afternoon, persisting into early evening at
least for the Charleston County nearshore waters. With a lull
anticipated early this evening and then another surge overnight
we could see more gales so the warnings may eventually need to
be extended for all or part of the area. Also, a few strong to
severe storms with gusts over 50 kt and waterspouts are possible
through the morning.

Tuesday through Saturday: In the wake of the front, wind will shift
from the west and speeds will gradually decrease. Gale Warnings will
likely end by Monday evening. Small Craft Advisory winds and seas
should remain through Tuesday. Marine conditions will begin to
improve Tuesday night with gusty northwest winds decreasing to less
than 15 knots and becoming northeast by Wednesday. Seas will follow,
dropping to 2-3 feet or less across all waters by Wednesday and
continuing through Thursday. Friday, winds will shift from out of
the south and will increase slightly with gusts near 20 knots. Seas
will gradually build up to 4 feet in the nearshore waters out 20 nm
and 4-5 feet in the outer GA leg.
