Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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.

The nearest sounding before it

Lincoln, IL (KILX), launched 12:00Z, 8.0 hours before the alert went out and 102 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

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 Jul 9, 1:16 PM CDT, 1 hour 45 minutes earlier. Its key messages:

  • Rain chances will be highest late this afternoon into early evening, then again Friday night. A few of the storms will be on the strong side, but the main threat of that will be south of I-72.
  • Locally heavy rain will result in the potential for areas of flooding, with the focus shifting more into areas south of I-72 by Friday night.
  • Temperatures remain typical for July. While a warming trend takes place next week, humidity levels will make it feel less oppressive than last week's heat wave.

.DISCUSSION...
Issued at 116 PM CDT Thu Jul 9 2026

Short Term (through Saturday):

Prominent MCV from the decaying convection across Missouri is
about to cross the Mississippi River south of Pittsfield.
Despite a fair amount of cirrus blowoff, MLCAPE's of 1000-1500
J/kg have allowed scattered storms to develop over the last hour
across eastern Illinois. Recent Day1 convective outlook shifted
the risk areas a little further south and are mainly
concentrated south of I-72. Greatest downdraft CAPE is expected
preceding the anticipated convection across central Illinois,
though there remains some uncertainty with the extent of
strong/severe storms. In general, much of the shower/storm
activity is expected through sunset. While development of
another MCS across Missouri is expected this evening, most of
the high-res guidance keeps this to our southwest.

A front across Iowa and southern Wisconsin is expected to only
slowly drift southward the next couple days. Additional
convective complexes are expected to ride along the boundary
Friday night, and highest rain chances remain over the south
half of the forecast area during this time. East-west upper
troughing will set up during the weekend, keeping the frontal
movement on the slow side. However, by late Saturday night, it
should finally be near the Ohio River, ending the rain threat.

Long Term (Sunday through Thursday):

Little change in the forecast for next week. A sprawling upper
high will dominate a large portion of the CONUS to start the
week, before the ridging amplifies near the Plains by midweek.
This pattern will result in seasonably warm temperatures near 90
degrees in our area, though with the Gulf cut off, humidity
levels should not get as rough as last week's heat wave. Still,
heat index levels of 95-100 degrees are likely Tuesday-Thursday.

As the upper ridge establishes itself, we'll be on the periphery
of a northwest flow, which can be favorable for MCS activity.
Right now, that activity looks to be more across the Great Lakes
region, so a dry forecast will be maintained in the extended
period.

&&

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1225 PM CDT Thu Jul 9 2026

Thunderstorms are expected to develop early this afternoon, as a
small scale disturbance moves out of Missouri. Main focus for
convection will be in the KSPI-KCMI corridor, closest to the
track of this feature. Will include a 3-4 hour TEMPO period in
this area for the highest potential, but maintain PROB30 groups
at KPIA/KBMI where development is less certain.

Going later into the night, focus shifts toward MVFR or
potential IFR conditions, as a front settles into the area and
winds become nearly calm. HREF probabilities of ceilings below
1000 feet peak around 11-13z at 40-60%. Will need to watch for
this potential with upcoming TAF issuances, but for now,
will go with MVFR ceilings mainly on the lower end.
