What forecasters said that day

The local office's own words before this heat advisory 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 heat advisory went out at Aug 9, 12:25 PM CDT, 1 hour 29 minutes earlier.

Area forecast discussion, Aug 9, 12:25 PM CDT, 1 hour 29 minutes before
Area Forecast Discussion
National Weather Service Lincoln IL
1225 PM CDT Mon Aug 9 2021

.SYNOPSIS...
Issued at 244 AM CDT Mon Aug 9 2021

Scattered showers and storms will affect the area this morning,
with locally heavy rain possible. Strong to severe storms could
affect parts of northern and central IL, primarily north of I-74,
late this afternoon and evening. Otherwise, hot and humid
conditions will prevail this afternoon, with heat indices between
95 and 100 degrees. The hot and humid, and unsettled weather
pattern, will persist through mid week. Dangerously high heat
indices above 105 degrees are possible Tuesday.

&&

.UPDATE...
Issued at 1032 AM CDT Mon Aug 9 2021

Surface analysis this morning depicts low pressure centered over the
tri-state region of WI, IA, and MN. Showers and storms are noted
across northern IL along and south of a warm front. Showers and
storms are also ongoing across east-central and southeast IL, tied
to remnant moisture transport with a waning LLJ. Expect this
activity to gradually taper off and spread east through early
afternoon. The question remains on how far east clearing will get
today. As of 15Z, low clouds have started scattering out across
western IL with a thin blanket of cirrus still present.
Temperatures are anticipated to remain highest across the
aforementioned areas of clearing, with heat indices possibly
exceeding 100 across these areas. Heat indices should remain below
Heat Advisory criteria today, but tomorrow will likely need a
heat headline. Additional chances for storms remain possible this
evening, though there remains uncertainty how far south said
storms will get. A few runs of the latest CAMs suggest much of
this activity will stay north of the local area as it follows the
CAPE gradient which will be collocated with the better shear. Will
be evaluating this closely throughout the day.

&&

.SHORT TERM...(Today and tonight)
ISSUED AT 244 AM CDT Mon Aug 9 2021

Scattered showers and storms have redeveloped over the area
overnight and early this morning, in response to a convergent
30-40 kt LLJ oriented from MO into central IL. This has provided
good moisture transport in the 925-850 mb layer, and will persist
for the next several hours until the jet diurnally weakens after
sunrise. Pockets of locally heavy rain will be the concern this
morning as PWs remain high at 1.8-2.0" (highest SE IL) even after
last evenings MCS. Radar estimates show rainfall rates at 1-2"/hr
recently in Clay Co. so isolated flash flooding possible where
training storms occur.  Expect convection to diminish from the
west, finally fading out over east/SE IL by midday.

The bulk of the afternoon should be quiet, as attention turns to
the north and a seasonably strong shortwave trof tracking into the
southern Great Lakes. A shortwave rotating through the base of
the trof in southern WI is expected to form convection in northern
IL during the afternoon to early evening. The airmass will be
characterized by high instability and moderate deep layer shear in
this region, leading to potential supercell development. HREF and
individual CAMs keep most of this activity just northeast of the
CWA as it dives southeast along the CAPE gradient through the
evening. Locations near and northeast of I-74 bear watching if
storms can propagate far enough south and pose an evening severe
weather threat. This is the area outlined by the SPC Day 1 Slight
Risk.

Highs today will be dependent on the amount/speed of clearing
after morning convection, so have trended highs from 85 in east
central IL to near 90 in west central IL. Dewpoints will be
oppressively high due to the recent rains and evapotranspiration,
in the mid 70s. This will result in 95-100F afternoon heat
indices. Winds remain high for the season in southwest gradient
flow with 20-25 mph gusts.

.LONG TERM...(Tuesday through Sunday)
ISSUED AT 244 AM CDT Mon Aug 9 2021

Dangerous heat and humidity is still on track for Tuesday, when
mid level flow turns zonal and southwest flow persists below 900
mb. Mid to upper 70s dewpoints will combine with highs in the
lower 90s for 103-108F heat indices, so a Heat Advisory will
likely be needed. Convective trends are more uncertain due to lack
of a trigger, though with a very unstable airmass if something
goes up along a remnant boundary or subtle wave, damaging wind
gusts possible and noted by SPC Day 2 slight risk CWA-wide.

Temperature trends are similar for Wednesday and Thursday with no
change in the synoptic pattern, so aside from convective
influences, we may be near Heat Advisory criteria again. Regarding
convection, low amplitude waves in the quasi-zonal flow will keep
thunderstorm chances in the forecast Tuesday night through
Thursday night. Difficult to pin down timing specifics with a
spread in model solutions, so chance pops are warranted. Given the
very moist and unstable airmass, severe and heavy rain threats
will be monitored.

Medium range guidance continues to depict a late week pattern
change, as the upper level jet dives into the Great Lakes, pushing a
cold front through the region Thursday night or Friday. NBM pops
with the frontal passage are low due to better dynamics well off
to the east. Surface high pressure then builds across the Midwest
next weekend, bringing in a cooler and less humid airmass.

&&

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1225 PM CDT Mon Aug 9 2021

Clouds are thinning from west to east early this afternoon with
all airfields expected to lift into VFR category over the next
hour or two. Thunderstorms are expected to develop over northern
IL later this afternoon into evening, though there remains
uncertainty with when and how far south they will travel. Held
onto VCTS at our northern TAF sites for the time being. Breezy
south winds with gusts of 20-25 kts persist through this afternoon
before lessening some overnight.
