Area Forecast Discussion
National Weather Service Charleston SC
612 AM EDT Mon Aug 3 2020

.SYNOPSIS...
Isaias will bring significant impacts to our area through
tonight. After the storm moves away, a stationary front will
then hover over or near the area mid to late in the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
No significant changes to the forecast based on the 5 AM NHC
Advisory on Tropical Storm Isaias, which is still expected to move
north from just off the east-central FL coast to a position very
near the northern Charleston County coast this evening while
strengthening to a Cat 1 hurricane. There is even a small chance
that landfall could occur somewhere near the Santee River.

Hazardous conditions are expected across much of our forecast area,
mainly near the GA coast and extending into the SC Lowcountry,
especially near and east of I-95. Conditions will steadily
deteriorate through the day, with the peak period of impacts
expected mainly this afternoon through the evening. Tropical storm
force winds, heavy rainfall, coastal flooding, rip currents, and
high surf are anticipated. Isolated tornadoes are also possible,
mainly near the Charleston County coast later this afternoon into
this evening when Isaias will make its closest approach. Tropical
Storm Warnings remain in effect for the entire coast and across the
Charleston Tri-County. We have also issued a Wind Advisory just
inland from the TS Warnings for Effingham, Hampton and Inland
Colleton Counties as these areas are most likely to see squalls
which could cause gusts of 40 mph or more and lead to minor
tree/limb damage and possible power outages. The most rainfall
is likely around the Charleston Tri- County where 6 inches or
more are possible. Widespread significant flooding could occur
near the coast, including Downtown Charleston, IF the peak storm
surge occurs around the time of high tide near 9 PM.
Temperatures will be lower today given the expansive clouds/rain
with highs mostly in the mid 80s except some upper 80s across
interior GA where the least cloud cover and rainfall are
expected.

Conditions will quickly improve from south to north tonight as
Isaias moves away to the north with the rain ending and wind
subsiding. Lows tonight should mainly be in the lower to mid
70s.

&&

.SHORT TERM /TUESDAY THROUGH THURSDAY/...
Tuesday: Isaias will be far to the north of our area in the morning
and continuing to quickly move away as it gets absorbed into a mid-
level trough along the East Coast. Meanwhile, relatively drier air
be in place across our area in the morning. Though, a cold front
should approach our area from the west in the afternoon, then
transition to a stationary front during the evening and overnight
hours. Models indicate some sea breeze convection forming in the
afternoon, with the highest probabilities across our GA counties.
There doesn't appear to be much instability in place, so the severe
risk is low. The convection should dissipate in the evening, then
transition to the coastal waters overnight. Afternoon temperatures
should peak in the 90s while overnight lows will generally be in the
70s.

Wednesday and Thursday: A mid-level trough will stretch from the
Great Lakes Region down into the Deep South. Meanwhile, a stationary
front will generally be just west of our area. Models are in good
agreement showing a return to our typical summertime pattern. High
temperatures should be in the low to mid 90s. Instability and lift
from the afternoon sea breeze are expected to fire off
showers/thunderstorms. Though, the details will need to be refined
as this time period gets closer. Some convection could persist into
the overnight hours. Lows are forecasted to be in the 70s.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
A mid-level trough will persist over the East Coast while a
stationary front hovers over or near area. The typical afternoon and
evening showers and thunderstorms are expected. Temperatures should
be near normal.

&&

.AVIATION /10Z MONDAY THROUGH FRIDAY/...
VFR conditions should mostly prevail at KCHS/KSAV through about
15Z Monday before conditions deteriorate to at least MVFR but
likely IFR or worse at times as bands of squally showers and
isolated storms shift west through the area ahead of tropical
cyclone Isaias. Winds will also steadily increase even outside
of the rain as Isaias nears the area from the southeast with
gusts up to 20-25 kt at KSAV through about 00Z Tuesday and gusts
to around 40 kt at KCHS from around 21Z Monday through about
03Z Tuesday. Stronger winds gusts will be possible however in
the heaviest showers/storms. Conditions could improve to VFR
late in the 06Z TAF period at KSAV.

Extended Aviation Outlook: Brief flight restrictions are possible
within showers/thunderstorms, mainly each afternoon through Friday.

&&

.MARINE...
Today and Tonight: Tropical Storm Isaias will move north through
the local waters bringing dangerous marine conditions, while
possibly strengthening to a minimal hurricane. Tropical Storm
Warnings remain in effect for the entire area including the
Charleston Harbor, although Hurricane Warnings could be needed,
especially for the offshore GA waters and Charleston County
nearshore waters. Conditions will also be favorable for
waterspouts especially from late morning through early evening.
Expect quickly improving conditions from south to north tonight
as Isaias moves away to the north. We could need Small Craft
Advisories in the immediate wake to at least account for
residual elevated seas.

Tuesday through Saturday: Any marine headlines in effect Tuesday morning
should be due to elevated seas from the storm. Though, they will
quickly subside into Tuesday afternoon as the storm moves away. A
stationary front is then forecasted to stay along the Southeast
coast mid to late this week, leading to a return of the typical
summer conditions. Winds and seas are expected to remain below Small
Craft Advisory criteria during this time period.

Rip Currents: Dangerous surf conditions are expected through
tonight as Isaias moves north just off the southeast Georgia
and southeast South Carolina coasts. Nobody should enter the
water during this time.

On Tuesday, remnant swell from the departing storm will
be moving through the coastal waters. The combination of this swell,
winds gradually turning onshore, and new coastal bathymetry in some
areas post storm will make it easy for rip currents to form. A
Moderate Risk is now in effect.

&&

.HYDROLOGY...
Periods of heavy rainfall are expected today as outer bands of
Isaias move inland across the area. More steady heavier rain is
then likely to push into the SC coast later today into this
evening and the highest total rainfall amounts are expected
generally around the Charleston metro where 6 or more inches
could fall. Our biggest concern is the threat for heavy rain
during the evening high tide which could cause significant
flooding in areas like Downtown Charleston due to the
combination of freshwater and tidal flooding.

&&

.TIDES/COASTAL FLOODING...
With a forecast of storm surge inundation in the 2-4 ft range, a
Storm Surge Warning remains up from Edisto Beach north through the
South Santee River. The best chance of seeing the peak inundation of
4 feet will be if Isaias makes landfall in our forecast area, mainly
in areas just to the right/north of landfall. Where the SS Warning
is in place, no Coastal Flood Advisories/Warnings will be issued,
although south of the Storm Surge Warning area we will issue those
products as needed. However, at this time we do not anticipate
reaching major coastal flood thresholds south of Edisto Beach so a
Coastal Flood Warning is unlikely. However, this could change if
Isaias ends up being slower to arrive and/or stronger allowing the
peak surge to better align with the high tide.
