Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day

The local office's own words before this tornado 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 tornado warning went out at Aug 1, 11:06 AM CDT, 53 minutes earlier. Its key messages:

  • A few waves of storms will move through the area between this morning and afternoon. Some of these storms could be strong to severe with a slight risk (level 2 of 5) in place over the entire forecast area.
  • Heat indices have the potential to exceed 100 degrees south of I-70 this afternoon, but storms and leftover cloud debris could inhibit this from occurring.

.KEY MESSAGES...

- A few waves of storms will move through the area between this morning
  and afternoon. Some of these storms could be strong to severe
  with a slight risk (level 2 of 5) in place over the entire
  forecast area.

- Heat indices have the potential to exceed 100 degrees south of
  I-70 this afternoon, but storms and leftover cloud debris could
  inhibit this from occurring.

.UPDATE...
Issued at 1104 AM CDT Thu Aug 1 2024

Late this morning, outflow from the morning round of storms has
sunk south of the CWA and is evident on satellite imagery
stretching from just south of Flora to Mount Carmel. West of this
boundary, a line of showers and a few storms has seen some uptick
in intensity over the past hour and anticipate this trend to
continue as storms move into a more unstable environment to the
east. SPC mesoanalysis shows 1500 J/kg MLCAPE with diminishing
MLCIN downstream of the current storms. Deep layer shear of 35-40
kt is also evident in this location along with the aforementioned
boundary which will locally enhance lift and SRH all pointing to
some threat for severe storms near our southern counties, but
greatest just south of our forecast area currently. In addition
to the severe threat associated with this boundary, it is also
worth noting that the heat and humidity are maximized south of the
boundary. Given its location and additional approaching storms,
this should preclude the need for any heat headlines in the
forecast area.

.DISCUSSION...
Issued at 317 AM CDT Thu Aug 1 2024

Upper analysis early this morning shows shortwave ridging over the
Midwest states with a closed 500 mb low approaching the upper
Mississippi Valley. At the surface, low pressure is centered over
southern Minnesota with a cold front stretched southwestward into
the central Plains and a warm front extending eastward into north-central
Illinois. Radar mosaic as of 3 am shows a few clusters of storms
in west-central Illinois and northern Missouri, being fed by
large-scale ascent tied to the upper low, MLCAPE of 2000+ J/kg,
and a ~30 kt LLJ. There is still some uncertainty regarding the
evolution of storms through this morning, especially across
central Illinois as they move into an area of weaker shear.
Instability is strong enough to support some stronger wind gusts
and hail, though storm organization may struggle the further east
it gets. The 01.06Z HRRR seems to have a decent handle on things,
which shows storms working across the entire area through early
morning, petering out near the Indiana border sometime between
8-10 am and leaving behind a remnant outflow boundary or MCV
somewhere over east-central parts of the state.

Remnant cloud cover from morning convection will slow
destabilization, but with high dewpoints in place MLCAPE is
projected to still be sufficient for storm development later in
the day. Temperatures (upper 80s to low 90s) and heat indices
(near 100 to 105) for this afternoon have been lowered from
our previous forecast. Heat headlines have not been issued due to
lower confidence in temperatures, but may need a second look for
areas near/south of I-70 later this morning after the first round
of storms ease.

The aforementioned upper trough will swing into northern Illinois
later today, spreading seasonably strong mid-level flow (30-35
kts) and large-scale ascent over the area. CAMs show a broken
line of storms developing near or south of the I-72 corridor by
early to mid afternoon and spread it east-southeast through early
evening. Discrete storms could pose a risk for all hazards
initially before transitioning to mostly a wind threat as they
grow upscale and congeal into a line. A separate area of storms
may develop further north closer to the upper low as lapse rates
steepen. A slight risk for severe storms has been expanded to
encompass the entire forecast area for today.

A cold front will push through late tonight, turning temperatures
more seasonable to close out the week. Dewpoints won't decrease
significantly behind the front, with values still expected to
remain in the low 70s. A lull in precipitation should generally be
seen Thursday night into Friday morning. However, moisture rich
air, steep low-level lapse rates, and the closed upper low nearby
should be enough to support isolated to scattered showers and
storms during the day on Friday. Weak shear by this time will keep
the threat for severe storms rather low.

Surface high pressure settles southward into the area by the weekend
as the upper ridge over west-central CONUS begins nudging eastward.
Precipitation chances remain minimal through the weekend until flow
aloft transitions back to northwesterly on the eastern periphery of
the ridge, bringing daily chances for precipitation back as early as
Monday. Temperatures this weekend into early next week will be near
or slightly above normal, but then look to turn cooler by the middle
or end of next week as the upper ridge breaks down and mid-level
heights gradually fall.

.AVIATION...  (For the 12z TAFs through 12z Friday Morning)
Issued at 625 AM CDT Thu Aug 1 2024

A few waves of storms will occur today, with the first ongoing here
this morning. Another round is possible by this afternoon, but
placement and timing of storms still remains uncertain. The
better chances for afternoon storms look to be east of I-55, so
kept the mention of VCTS at these terminals for now. MVFR to
occasional IFR conditions will be possible with any thunderstorms,
but otherwise VFR will prevail. Winds will generally be out of
the south-southwest today then veer to the west-northwest
overnight as a cold front moves through.

MVFR to IFR conditions look common by Friday morning with the HREF
showing high probabilities for ceilings <2k ft arriving around or
shortly after 12Z.
