What forecasters said that day

The local office's own words before this flash flood warning went out, 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 this flash flood warning went out at Jul 7, 2:53 PM CDT, 2 hours 4 minutes earlier.

Area Forecast Discussion
National Weather Service Paducah KY
253 PM CDT Thu Jul 7 2022

.SHORT TERM...(Tonight through Friday night)
Issued at 253 PM CDT Thu Jul 7 2022

Main forecast concern is the timing and coverage of thunderstorms,
which will impact the excessive heat. An early morning mcv brought
widespread clouds and rainfall to southwest Indiana and the
Interstate 64 corridor. This mcv is moving east, and the back edge
of the precip was nearing the Wabash Valley as of 1930z.
Elsewhere, isolated storms have developed along a surface boundary
that extended from the Wabash Valley to near kpof.

The forecast for the next 24 hours hinges on mesoscale features,
but the models have been hit or miss with features such as this
mornings mcv. This afternoons convection has a few more hours to
increase. After today's surface-based storms decrease early this
evening, there is some potential for another elevated round of
storms late tonight.

A consensus of the short-range model pops hints that the
Interstate 64 corridor and southwest Indiana will once again be
most likely to receive elevated storms late tonight. The href mean
wind fields indicate a modest southwesterly 850 mb low level jet
will develop overnight. This appears to be in response to a 500 mb
impulse that will track eastward across the mid Mississippi
Valley. Along the nose of the stronger low-level flow, another
round of convection appears likely overnight.

Once again on Friday, convection is likely to develop along
outflow boundaries associated with convective complexes from early
in the morning. The timing appears to be similar to the past few
days, with the outflow boundaries becoming active about mid
afternoon. This scenario would result in little if any difference
in heat indices compared to the past few days. Therefore, the
Excessive Heat Warning will be extended through Friday for the
areas that are currently covered. The thinking is that areas
further north and northeast will again be affected by morning
clouds and showers.

Showers and thunderstorms will be slower to diminish Friday night
as a cold front provides forcing for development through the
night. The href 6-hourly mean qpf maximizes between 00z and 06z on
Friday night over western Kentucky. Given the very high moisture
content and slow movement of the storms, some locally heavy
rainfall is likely. However, a widespread heavy rain seems
unlikely given the lack of a well-defined synoptic scale 500 mb
shortwave. Low stratus and fog may form Friday night in the wake
of locally heavy rainfall. Winds will be light.

.LONG TERM...(Saturday through Thursday)
Issued at 253 PM CDT Thu Jul 7 2022

Models indicate the frontal boundary and most of it's associated
convection will be south of the KY/TN border by Saturday morning.
However, low level moisture will be slower to scatter out. This will
lead to plenty of cloud cover, at least through early afternoon.
With the lingering moisture, isolated convection may still develop
through the day, mainly in western Kentucky. However, tend to
believe the NBM PoPs are likely still too high, and probably will
need to trim those back some with future packages. Have nudged down
temperatures into the low to mid 80s, but wouldn't be surprised if a
few areas struggle to reach 80 if few breaks in the clouds are
realized.

High pressure will build south from the Great Lakes Saturday night
into Sunday. Dry northeasterly flow will funnel lower humidity
(dewpoints in low to mid 60s) into the region. Plenty of sunshine is
expected on Sunday with highs a bit below normal in the mid to upper
80s.

As the surface high moves east, southerly flow develops again on
Monday. This will lead to a rise in temperatures back into the 90s
on Monday and Tuesday. Slight uptick in humidity levels will be
realized on Monday, and more so on Tuesday as moisture pools ahead
of an incoming front.

Models are in good agreement in bringing a cold front into the area
Tuesday into early Wednesday. However, they differ as to how much
precipitation develops along the boundary across our cwa. The GFS
and its ensemble are the most aggressive while ECMWF and Canadian
ensembles aren't overly impressive with areal coverage and overall
QPF. For now feel like the slight PoPs the NBM initialized with is a
good way to go.

Behind the frontal boundary, surface high pressure builds back into
the Great Lakes region later next week. This allows dry northerly
flow to funnel below normal temperatures in the 80s back into our
area.

.AVIATION...
Issued at 1055 AM CDT Thu Jul 7 2022

VFR conditions continue at the taf sites. However, isolated to
scattered thunderstorms are forecast through this evening. IFR
conditions will occur in any storms, but coverage of storms
appears too low to mention in the kpah/kcgi tafs at this time.
The kevv/kowb area is most at risk for storms in the immediate
future, and thunder has been added to those tafs.

southeast Missouri, most of western Kentucky, and southern
Illinois south of the Interstate 64 corridor.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Thunderstorms are again in the forecast for Friday and Friday
night. The strongest storms are expected in the afternoon and

The Excessive Heat Warning has been extended through Friday for
much of the area except southwest Indiana, the Interstate 64
corridor of Illinois, and far northwest Kentucky. Peak heat
indices will again be up to around 110 degrees on Friday.

A few isolated thunderstorms may linger into Saturday, mainly across
western Kentucky. Another chance for thunderstorms returns Tuesday
into Wednesday.
