The episode as NWS PAH wrote it up.
Thunderstorms repeatedly generated over parts of southwest Indiana along a convergence axis in the mid levels of the atmosphere. A remnant upper-level disturbance over western Illinois moved southeast, providing support for the storms. The atmosphere was very moist, with precipitable water values over 2 inches.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Paducah, KY wrote its last area forecast discussion before the first event at Aug 3, 3:05 AM CST, 2 hours 28 minutes earlier.
Area Forecast Discussion
National Weather Service Paducah KY
405 AM CDT Thu Aug 3 2023
.SHORT TERM...(Today through Saturday night)
Issued at 405 AM CDT Thu Aug 3 2023
Very busy night, so will try to be brief.
Will leave the Flood Watch intact for the entire region through
18z. The main area of concern will be along and west of the
Mississippi, as more intense convection slides southeast over that
region. We will also have to keep an eye on the far northeast for
any training up there, although the convection there is much
weaker. The general consensus is for the entire area to be dry by
18Z, so the end time looks good.
As for the Heat Advisory, we added Carter and Wayne counties.
There is a lot of variability in the guidance temperatures today,
the worst being the HRRR with around 100F! Most dewpoint guidance
has at least middle 70s, so if they get some sunshine over there,
it could get pretty disgusting. We could conceivably need to
expand it over the rest of southeast Missouri, depending on cloud
cover.
There is a signal in the guidance for another round of nocturnal
convection late tonight into Friday morning, mainly over southeast
Missouri and into the Purchase Area. The low-level warm advection
will be much weaker and accordingly, WPC QPF is well under an
inch. However, depending on how bad things get with this current
event, we could need a more focused Flood Watch, especially if the
QPF increases in the 12Z cycle.
It sounds like a broken record, but another round of nocturnal
convection will be possible late Friday night into Saturday.
However, the flow aloft will become nearly zonal, so there may be
more progress into the eastern half of the area through the day
Saturday.
The NBM temperatures were generally accepted through the period.
With the possible exception of southeast Missouri today, high
temperatures will be at or below normal. Lows will be a few
degrees above normal through the period.
.LONG TERM...(Sunday through Wednesday)
Issued at 405 AM CDT Thu Aug 3 2023
A storm system will move eastward from the northern Plains into
the Great Lakes by Sunday night. This will push a cold front
through the area late Sunday or Sunday night. The models indicate
that there will be some pretty good westerly flow aloft along and
even a bit ahead of the front, so there could be some decent shear
to play with in the warm sector. Dewpoints will be in the middle
70s, so assuming some decent sunshine, we should be plenty
unstable to support severe storms, given the expected shear.
Behind the cold front, the entire region should be dry with lower
humidity and below normal temperatures Monday through Wednesday.
South winds will return Wednesday, and another storm system and
cold front could impact the Quad State Wednesday night into next
Thursday.
&&
.AVIATION...
Issued at 1249 AM CDT Thu Aug 3 2023
Modeled the TSRA/SHRA timing after 04Z HRRR. The convection will
bang around most of the region through around 15Z, but then we
should be dry for the remainder of the period. Some MVFR or lower
ceilings will be possible behind the convection and that could
last for much of the day in the northeast. Mid-level ceilings
should keep temperatures from warming much, and we could see some
fog or low cloud formation by late evening.
