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.

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 10, 3:51 PM CDT, 0 minutes earlier.

Area forecast discussion, Jun 10, 3:51 PM CDT, 0 minutes before

Area Forecast Discussion
National Weather Service Lincoln IL
351 PM CDT Sun Jun 10 2018

.SHORT TERM...(This evening through Monday)
ISSUED AT 351 PM CDT Sun Jun 10 2018

Severe thunderstorms moving through east central IL at this time
expected to continue for at least the next 2-3 hours. Keeping an
eye on another storm, and possible additional development, in west
central IL from near UIN through Rushville to Petersburg. SVR
Watch cancelled to the north of this activity, including PIA and
BMI. Additional showers and t-storms in scent Iowa slowly
translating east to east-southeastward. Thus, will keep the
mention of showers and t-storms in the forecast into Monday
morning.

Another very warm and humid day is in store for much of the area
Monday with temperatures 85-90 degrees. Could see a few late
afternoon/evening t-storms Monday...particularly in southeast and
east central IL along the synoptic front expected to be just north
of I-70.

&&

.LONG TERM...(Monday night through Sunday)
ISSUED AT 351 PM CDT Sun Jun 10 2018

A deep upper trough in the Pacific NW is expected to rotate NE
from the Canadian Rockies toward Lake Winnipeg. This will push the
upper level ridge to the east of the western Great Lakes, allowing
a cold front to advance toward the Midwest. The front is expected
to move across the forecast area during the day Tuesday, resulting
in another potential for showers/t-storms.

A drier airmass will move in behind the front for Wednesday,
although temperatures will remain on the very warm side. The dry
weather will be short lived as a warm front lifts toward central
IL and shortwaves interact with the front to give us showers and
thunderstorms from Wed nite through Thursday nite.

The longer range models are in a bit of disagreement for late in
the week and into the weekend. The GFS and Canadian keep the main
upper ridge to the west of the our region, while the European
breaks it down and shifts it through IL. For now will side with
the more pessimistic GFS/Canadian solution and go with a chance
for t-storms late Friday into Saturday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 112 PM CDT Sun Jun 10 2018

Very active period in the weather for this afternoon/early evening
and again overnight in central and eastern IL. Strong to severe
thunderstorms near KPIA are expected to expand and spread toward
east central IL by early evening. Some existing storms in east
central Il at 18Z are expected to remain below severe limits and
exit the region around KCMI by 19-20z.

Additional t-storms, associated with a convective complex in
central IA, are expected to move into central IL later this
evening. Much of the lower atmosphere is expected to be stabilized
from the earlier convection, so the main concerns are expected to
be moderate/heavy rain and then lowering ceilings as a more
stratiform precipitation shield approaches. Most TAF sites in
central IL are expected to drop into the MVFR ceiling category,
but will need to watch closely for IFR conditions after midnight
and through daybreak.
