.DISCUSSION...
Issued at 341 PM CDT Sun Jun 21 2026

*** Tornado Watch ***

20z/3pm radar imagery shows a band of rain with embedded
thunderstorms pushing across central Illinois. The pre-storm
environment remains stable across a large portion of the area:
however, MLCAPEs have increased to 500-1000J/kg south of a warm
frontal boundary draped along the I-70 corridor. With surface
dewpoints in the upper 60s/lower 70s in the warm sector, RAP
suggests further destabilization over the next 3-4 hours as
MLCAPEs reach 1000-1500J/kg. Deep-layer shear is currently being
augmented by an approaching MCV, while 0-1km shear has increased
to 20-25kt near the boundary. As a result, the southern part of
the rain band now contains rotating supercells capable of
producing tornadoes and damaging wind gusts. A Tornado Watch has
subsequently been issued for locations along/south of a
Shelbyville to Paris line through 9pm. Based on radar trends and
latest HRRR/RAP data, it appears the primary storm risk will
push into Indiana by 6-7pm. Meanwhile further west, will have to
keep an eye on a broken line of much weaker cells currently
firing along a Quincy to Kansas City line. These storms are in a
much more unfavorable environment and are not expected to
become severe: however, gusty winds will still be possible into
the evening as they spread E/SE into central Illinois...mainly
along/south of the I-72 corridor.

*** Quiet Mid-Week ***

Cool/dry weather will settle into the region for Monday and
Tuesday with daytime highs well below normal for this time of
year in the 70s and overnight lows dipping into the 50s. Given
persistent upper troughing over Canada, northwesterly flow will
continue for the rest of the week. The next embedded short-wave
trough and accompanying cold front will push through central
Illinois on Wednesday. While deep-layer moisture will be
lacking, there will be strong enough forcing to warrant low
chance PoPs (30-40%) for showers/thunder, especially during the
afternoon and evening.

*** Weekend Warm-Up and Storm Risk ***

The mid-week frontal boundary is progged to stall across the
Ohio River Valley on Thursday, then begin lifting slowly back
northward by the weekend as upper heights rise in response to an
upstream trough digging west of the Rockies. While the exact
speed of this process is still in question, model consensus
indicates the most favorable period for rain will be from late
Friday through late Saturday when several bouts of convection
may develop along/north of the front. It is still too early to
discuss any specific severe weather risks: however, all machine
learning algorithms show low probabilities (less than 15% chance)
for severe. Once the boundary lifts into the Great Lakes, a
return to more typical summertime weather is anticipated for
early next week. In fact, the 12z NBM shows a 30-50% chance for
temperatures climbing above 90 degrees by next Sunday.

.AVIATION /00Z TAFS THROUGH 00Z TUESDAY/...
Issued at 652 PM CDT Sun Jun 21 2026

2330z/630pm radar imagery shows scattered convection persisting
along/east of the I-55 corridor. Based on radar trends and
latest HRRR/RAP analysis, have opted to leave thunder mention
out of the TAF for the I-74 terminals. Further south, have
maintained a 1-3 hour window of thunder between 00z and 03z at
KSPI/KDEC. Once the convection pushes further east, the primary
aviation forecast concern will be low ceilings tonight into
Monday morning. A large area of IFR clouds across Iowa into
western Illinois will pivot southeastward into the area over the
next several hours...with the HRRR suggesting all sites down to
IFR after 05z. The low clouds will gradually dissipate/scatter
from northwest to southeast toward midday Monday...with partial
clearing expected across the board during the afternoon. Winds
will become NE with gusts of 20-25kt at KPIA/KBMI this evening
as low pressure tracks through the heart of central Illinois.
Further south, winds will veer to NW tonight, then eventually to
NE by Monday morning.
