Charleston AFB, SC (KCHS), launched 12:00Z, 7.4 hours before the alert went out and 37 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this special weather statement 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 special weather statement went out at Jun 9, 1:33 PM EDT, 1 hour 52 minutes earlier.

Area forecast discussion, Jun 9, 1:33 PM EDT, 1 hour 52 minutes before
Area Forecast Discussion
National Weather Service Charleston SC
133 PM EDT Thu Jun 9 2022

.SYNOPSIS...
A cold front will pass across the region today into tonight,
before stalling in the vicinity into the weekend. Another front
could arrive early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Mesoanalysis still shows quite a bit of Convective Inhibition
(CINH) across the area. As a result we haven't seen much cumulus
development thus far. Fairly deep W-WSW flow in the low and mid
levels will prevent the sea breeze from making much inland
progress this afternoon. As temps gradually warm into the mid
and upper 80s, The CINH should dissipate and the cap will
weaken, allowing some Cu development and a few showers or tstms
along the sea breeze. Much of the convection will likely be
hugging the coast where the sea breeze gets pinned. Activity may
develop along the sea breeze and then shift offshore in response
to the stronger westerly flow aloft. Later this afternoon we
could see additional development across southeast GA in response
to a shortwave moving through the area. The severe potential is
relatively low, but with ML-CAPE approaching 2,000 J/kg by later
this afternoon, we can't rule out a few marginally severe
storms.

Tonight: A few showers may linger through the evening as the
boundary finally moves through, exhausting the last bit of CAPE.
Drier weather for the overnight with low temperatures dipping
into the upper 60s to lower 70s...a little cooler than in recent
nights.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY/...
A cold front will stall in the vicinity on Friday. Couldn't
rule out a couple brief showers/thunderstorms in the afternoon,
but think coverage will remain too isolated to include explicit
mention in the forecast with dry air still present in the mid
levels and lack of any notable features aloft. Highs are
forecast to reach around 90 into the lower 90s closer to the
Altamaha. Lows Friday night will be within a few degrees of
normal.

A mid level trough will prevail over the eastern U.S. on Saturday.
At the surface, a broad area of low pressure will likely be
positioned over the Carolinas. Sufficient moisture and instability
will lead to the development of scattered showers and thunderstorms.
Coverage will peak in the afternoon into the evening, but some
activity could persist overnight as well. Temperatures will be
seasonable.

A surface trough of low pressure/stalled front will likely linger in
the area through Sunday. Aloft, trough will begin to weaken in
response to a large ridge over the Southern Plains building east.
Isolated to scattered convection will be possible, especially closer
to the coast in proximity to the deeper moisture. Highs will mainly
be in the lower 90s.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
The main weather influencer in the long term period will be a large
mid level ridge expanding eastward into the region. This pattern
favors lower rain chances and warmer temperatures, though it's worth
noting some models show shortwaves dropping out of the northwest
flow aloft which could enhance convection potential at times. The
forecast currently keeps rain chances no higher than 20%. Otherwise,
the story will be the unseasonably hot temperatures. Highs are
expected to reach the mid to upper 90s inland of the coast. Will
need to monitor the potential for heat indices to reach the pre-July
1 criteria of 105F.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
Scattered convection could briefly affect any terminal this
afternoon or evening. The best coverage will probably be south
of KSAV so at this juncture we cannot pin down timing at a TAF
site better than a vicinity thunder mention. By late this
evening most activity should be off the coast after the passage
of the cold front.

Extended Aviation Outlook: Prevailing VFR. Brief restrictions
possible with mainly afternoon showers/tstms over the weekend.

&&

.MARINE...
South to southwest winds will persist through tonight. Winds
will tend to weaken this afternoon and tonight and eventually
veer west or northwesterly later tonight with passage of the
cold front.

Meanwhile, another round of thunderstorms is anticipated this
afternoon, developing along the coast then moving out into the
coastal waters. Gusty winds will be a threat with any storms
that develop with the potential for Special Marine Warnings.

Friday through Tuesday: Marine conditions are expected to stay below
Small Craft Advisory criteria through the period. A stalled front
will linger in the vicinity into the weekend. Higher pressure should
return next week. Aside from a brief period of northeast/east winds
early Friday, winds will predominantly be out of the southwest.
Speeds will average around 15 knots or less with seas will 2-4
feet.
