What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Lincoln, IL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 29, 12:47 PM CDT, 40 minutes earlier.

Area forecast discussion, Jun 29, 12:47 PM CDT, 40 minutes before
Area Forecast Discussion...Updated Aviation
National Weather Service Lincoln IL
1247 PM CDT Thu Jun 29 2023

.SYNOPSIS...
Issued at 1238 PM CDT Thu Jun 29 2023

Another round of severe thunderstorms are expected to track
quickly eastward over central and southeast IL during this
afternoon, with all hazards possible. This includes damaging winds
of 60 to 80 mph, large hail 1 to 3 inch diameter and possible
tornadoes along with heavy rains. Highs today in the mid to upper
80s with muggy and hazy conditions before the storms. An air
quality alert continues through 7 pm today, but smokey conditions
should improve as the storms race eastward across central IL
through this afternoon. More severe weather is possible Friday
and this weekend with more rounds of thunderstorms.

&&

.DISCUSSION...
Issued at 249 AM CDT Thu Jun 29 2023

-----------------------[KEY MESSAGES]-----------------------

1. Severe weather is on deck for today, with the potential of
multiple rounds throughout the day. All hazards are possible.

2. Smoke lingers over central Illinois with hopes that it will move
out by this morning into the afternoon.

------------------------[DISCUSSION]------------------------

Looking at the set up today synoptically, we can see a prominent
500 mb ridge in place over much of the central United States. Many
of the convective complexes look as if they are "riding the
ridge", moving over the top of the ridging feature. This ridge is
likely a big player in the extreme temperatures much of the United
States will be dealing with for the next day or so, essentially
acting as a heat dome. However, the convection expected today will
limit temperatures. An upper level trough is pushing onto the
west coast. This will force the ridging pattern to weaken and move
off to the east and bring additional chances for rain and
thunderstorms to our CWA.

A surface low pressure system is moving across the Plains eastward
towards the Middle Mississippi and Ohio Valleys. The warm front
associated with this low will bring dewpoints of 70+ degrees to
central and southeastern Illinois. These dewpoints indicate the
abundance of moisture in the air, which will help aid in the
convective initiation in the early morning hours today. After the
warm front and surface low move away from central Illinois, multiple
surface boundaries are forecast to pass through over the next
several days.

Dropping down to the mesoscale details, we shall focus on the near
term (Thursday into Friday). As the storms begin to fire up this
morning, they are expected to be primarily elevated to start as they
are ahead of the warm front. These early storms' risks look to
mainly be hail, as there is quite a bit of capping that the winds
will have to break through to reach the surface. Depending on
location of the convective complex passage and its associated cold
pool, storms may be able to become surface based, which will greatly
increase the risk of strong, damaging winds. The storms that are
along or near the warm front have a chance for some tornadoes. SPC
has all of central Illinois in an enhanced risk for severe weather
[5% tor, 30% wind, and 15% hatched hail].

Based on the 00z/29 run of the NAM, MUCAPE values are widely 2500-
5000 J/kg for most of the night into Thursday afternoon/evening. The
capping over the region is keeping SBCAPE pretty low over eastern
Illinois but nearing 4000 J/kg over western Illinois. The surface to
500mb bulk shear shows a max of 50 kts over central Illinois this
morning (agreeing with the Euro/GFS/HRRR). The 00z/29 run of the
HREF ensemble show large swaths of areas with updraft speeds greater
than 20 m/s (sufficient for hail development).

The first round of convection is expect to start making its way
across the CWA just before sunrise. The second round closely follows
and potentially will move through by late morning or early
afternoon. Then a third round could move through by late tonight or
early Friday morning. Despite it being the extreme short term now,
there is still the uncertainty of where these complexes may move
through and how they will affect each other and the highs over the
next day or so.

In terms of the smoke and hazy conditions, the HRRR 00z run is
indicating that the smoke should start clearing out of the area just
after sunrise. Visibilities and air quality should begin to improve
shortly after. Basically, today is going to be much less smokey and
hazy than the previous 2 days.

If the convection plays out as expected, temperatures will be
greatly limited today and Friday - essentially depleting the heat
indices. The heat advisory for Lawrence/Richland/Clay counties has
been cancelled early. Saturday - Monday will see highs primarily in
the upper 80s but then by mid week highs in the 90s will return.
Currently, there is no heat indices in the forecast. There is a
chance for showers and thunderstorms throughout the extended period.

.AVIATION...  (For the 18z TAFs through 18z Friday Afternoon)
Issued at 1245 PM CDT Thu Jun 29 2023

Severe squall line racing eastward along I-55 and already affected
PIA and SPI with w/nw wind gusts 45-55 kts and about to affect
DEC and BMI prior to 18Z. Severe storms racing east at 55-65 mph
and to affect CMI by 1830-19Z with w/nw wind gusts 50-60 kts
likely. Hail and very heavy rains also risk along and east of the
IL river next 1-2 hours with IFR to MVFR conditions. A lull in
convection from this evening into mid Fri morning, but another
round of convection could roll in late Friday morning or Friday
afternoon. CAMs differ on evolution of next round of convection on
Fri and left thunderstorms out of TAFs for Friday morning.
