What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Charleston, SC wrote its last area forecast discussion before this gale warning went out at Sep 19, 1:47 AM EDT, 1 hour 48 minutes earlier.
Area forecast discussion, Sep 19, 1:47 AM EDT, 1 hour 48 minutes before
Area Forecast Discussion
National Weather Service Charleston SC
147 AM EDT Sat Sep 19 2020
.SYNOPSIS...
Strong high pressure will gradually build into the area over
the weekend and will persist through next week.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
No major changes with the latest update. High pressure will
continue to build from the north as low-level moisture advects
in from the north and higher level moisture advects in from the
southwest. Overall, conditions will be cloudy with temperatures
falling to the lower to mid 60s inland to near 70 at the coast,
warmest in GA.
Lake Winds: A Lake Wind Advisory remains in effect for Lake
Moultrie as vertical mixing of strong low-level winds over the
warm lake waters supports gusts to around 25 kt. Waves will
build to 1-2 ft, highest central and southwest portions.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH MONDAY/...
Saturday through Monday: Strong surface high pressure centered
over the Great Lakes region will gradually deepen as it
propagates eastward. Surface ridging will continue to build over
the weekend, with associated northeast flow eventually forming
a wedge pattern. As surface winds veer to the northeast after
the passage of the front, gusty winds will persist mainly along
the coast due to a tightening pressure gradient. Wind gusts
could approach Lake Wind Advisory criteria over Lake Moultrie
this weekend; however, the current forecast caps gusts around 20
kt.
Subsidence and a stable atmosphere should eliminate much
precipitation from developing over land. Weak instability over the
waters and deep moisture being advected from distant Hurricane Teddy
calls for slight chance PoPs due to the potential for isolated
showers developing. Strong northeast flow could push a shower
onshore in southeast GA; however, it will likely be short-lived and
light in nature. Model guidance hints at the greatest possibility
for rain over McIntosh County where deeper moisture exists. PoPs are
capped over this area near 20% considering the atmosphere is
relatively stable.
Much cooler temperatures are expected with high temps about 10
degrees below normal for this time in September. High temperatures
Saturday through Monday should only reach the low to mid 70s, and
min temps are forecast to drop below 60F inland with low to mid 60s
closer to the coast. Additionally, noticeably lower dew points will
make way for a drier, comfortable "autumn-like" setting.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
A wedge of high pressure and drier air will prevail across the
area through the middle of next week keeping rain chances to
minimum. High temperatures will gradually increase through the
week. Low temperatures could drop into the low 50s on Tuesday
and Wednesday. By late week, low pressure could approach the
area from the west and increase rain chances.
&&
.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
High confidence for the 06Z TAFs at KCHS/KSAV. Conditions will
mostly be VFR, although can't rule out some MVFR cigs at times,
mainly around 15Z. Strong NE winds are expected with gusts near
20 kt at times, especially late morning/early afternoon.
Extended Aviation Outlook: Brief MVFR conditions are
possible in low clouds this weekend. VFR expected thereafter.
&&
.MARINE...
Overnight: Winds will continue to slowly increase with gusts to
near 30 kt. Small Craft Advisories remain in effect for all
waters.
Saturday through Wednesday: Strong ridging will continue to
build over the waters further deteriorating marine conditions with
gusty northeast winds around 25 kt, 6-7 foot seas entering the
nearshore waters, and up to 10 foot seas in the outer waters on
Saturday. Winds and seas will continue to gradually increase,
following the strengthening pressure gradient as distant Hurricane
Teddy moves north-northwest closer to strong surface high pressure.
Seas could build up to 10 feet in the nearshore waters Sunday and up
to 15 feet in the outer waters as wind gusts increase to near 35
knots. A slow downward trend in the wind gusts and seas will occur
early next week; however, noticeable improvement in the marine
conditions will not be until Wednesday. Small Craft Advisories are
ongoing for all marine zones. The outer GA waters has been upgraded
to a Gale Watch beginning 16Z Saturday. AMZ374 may need to be
upgraded to a Gale Warning and the near shore waters may need to be
upgraded to Gale Watches/Warnings.
Rip Currents: Expect a moderate risk for Saturday. An elevated
risk of rip currents is expected to continue thereafter due to
elevated northeast winds gradually increasing and incoming long
period swell up to 16 seconds from distant Hurricane Teddy.
High Surf: Building seas over the weekend could lead to 5+ foot
breaking wave heights at the coast and thus High Surf
Advisories could be needed. This will likely lead to some beach
erosion.
&&
.TIDES/COASTAL FLOODING...
Significant coastal flooding is expected this weekend into
early next week. The combination of higher than normal astronomical
tides, river discharge, and strong NE winds will result in
flooding during both the AM and PM high tide cycles. PETSS
guidance remains missing due to a scheduled outage. The extra-
tropical guidance is suspected to be too low for the days 2-3
period. Based on the duration and strength of the wind field,
departures over astronomical tides should increase Saturday into
Sunday, the peak tide is forecast for Sunday morning. Peak
water levels may reach the highest since the Thanksgiving 2018
event for both the SC and GA coasts. The combination of the
AM/PM tides may result in 6-10 hours of water in excess of flood
stage each day. Given the long duration of water above flood
stage, it is possible that flooding may occur well upstream on
rivers and creeks with tidal cycles.
