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 11, 7:18 PM CDT, 7 minutes earlier.

Area forecast discussion, Jun 11, 7:18 PM CDT, 7 minutes before

Area Forecast Discussion
National Weather Service Lincoln IL
718 PM CDT Mon Jun 11 2018

.SHORT TERM...(This evening through Tuesday)
ISSUED AT 250 PM CDT Mon Jun 11 2018

Frontal boundary extends across southwestern counties this
afternoon with partly cloudy skies and temperatures in the 80s
southwest of the boundary and mostly cloudy conditions and temps
mostly in the 70s northeast of the front. Instability is limited
to the boundary and southwest. Chances of precip should be limited
north of the front until later this evening when weak wave
approaches after the main mid-level ridge axis gets east of the
area. Wave should induce a more southerly component to low level
flow and should allow moist/unstable air to overide cool air and
produce storms. Models are quite diverse regarding coverage and
intensity tonight and Tuesday. NAM Nest is most rubust with areas
of several inches forecast in some areas that received 3+ inches
from last night. Given precip water values (near 90 percentile for
mid-June) can not discount this entirely. With at least some
potential will be going with a small flash flood watch for areas
impacted yesterday that are close to the boundary.

.LONG TERM...(Tuesday night through Monday)
ISSUED AT 250 PM CDT Mon Jun 11 2018

Cold front should push through forecast area Tuesday with slightly
drier air and a lull in precip chances. Late in the week heights
build as flow becomes more meridonal and trough digs along the
west coast. Storm track should push north of the area with only
isolated storms expected within the ridge by the weekend. Abundant
sunshine and 850 mb temps around 20C will support temps into the
90s for the weekend with apparent temperatures topping 100.

&&

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 710 PM CDT Mon Jun 11 2018

A warm frontal boundary extending across the far southern portion
of our central Illinois forecast area will remain the focus for
periodic showers and storms over the next 24 hours. The primary
periods for storms look to be earlier this evening, and again
between 09z and 15z as a storm complex progresses out of Missouri
across our southern counties. SPI will have the better chances of
storms during both of those periods of the 00z TAF, with DEC and
PIA also possibly seeing some storms as well. Kept BMI and CMI dry
for now. The northern terminal sites may be dealing with MVFR/IFR
clouds and vis overnight as they remain in a saturated air mass
north of the warm front, especially later tonight into early Tues
morning.

Winds will prevail from the east this evening, then become
variable under the weak surface pressure gradient. A trend in wind
directions toward the southwest is projected for tomorrow. Wind
speeds look to remain less than 10kt in general.
