.KEY MESSAGES...

- Scattered showers and thunderstorms are expected through this
  evening, and into the overnight hours southeast of the IL
  river. Damaging winds, hail, heavy rains and localized
  flooding is in play today. A Flood Watch is posted until 1 am
  tonight from Fulton to Macon to Vermilion counties north where
  1-2 inches and locally 2-4 inches of rain possible.

  humidity levels in check the next several days, with
  seasonable highs in the upper 70s to mid 80s.

&&

.DISCUSSION...
Issued at 245 PM CDT Wed Aug 19 2026

We continued the Flood Watch through 1 am tonight from Fulton,
Mason, Menard, Logan, Macon, Piatt, Champaign and Vermilion
counties north. Some areas could see 1-2 inches of rain through
early overnight in central IL with pockets of 2-4 inches
possible. PWATs are in the 1.6-2 inch range over CWA (highest
over southern CWA) and supports heavy rain threat next several
hours. Parts of the flood watch area has already seen 5-10
inches of rain since last Sunday Aug 9th.

Radar mosaic shows a few cells developing along a frontal trof
from southern Fulton county into central parts of McLean and
Ford county. Had a recent report and photo of a funnel clouds in
Bloomington and Galva (southern Henry county). Moderately
unstable tropical airmass over CWA with SB CAPES of 2-3k j/kg,
and highest over northern/nw CWa. The 0-6 km bulk shear values
are at moderate levels too from 35-45 kts over CWA and highest
over southern/sw CWA. A cold front over northern/nw IL will push
se thru CWA during tonight, while an associated short wave trof
over western Iowa tracks se through IL during tonight. This
will interact with the tropical air mass to likely produce
scattered showers and thunderstorms. SPC Day1 outlook has
marginal risk of severe storms over CWA for large hail and
damaging winds while tornado threat is over southern IL south of
CWA though a few more funnels may occur along weak trof over
northern CWA through 00Z/7 pm.

Quieter weather expected on Thursday and Thu night as cold
front nearing the Ohio river by sunrise Thu pushes into central
KY. Highs in the lower 80s Thu with dewpoints in the mid to
upper 60s. A northern stream system approached IL on Friday
bringing 20-40% chance of convection over northern cWA Fri
afternoon and across central IL friday night especially Fri
evening. SPC keeps severe risk west nw of IL on Fri with slight
risk of Nebraska and northeast KS. Highs in the low to mid 80s
Friday with dewpoints sneaking up into the upper 60s/lower 70s
by Fri afternoon.

Fairly quiet weather this weekend into early next week with just
slight pops at times while most areas should stay dry. Another
cold front to sweep through IL early Saturday and bringing in
less humid air during this weekend. Lows Saturday night in the
lower 60s and lows in upper 50s to around 60F Sunday night
making for more comfortable nights ahead. Highs Sat 80-85
(warmest in southeast IL) and upper 70s/lower 80s Sunday/Monday.
Still pretty not much weather expected into middle of next week
with some moderation of temperatures and dewpoints to more
summerlike readings.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 632 PM CDT Wed Aug 19 2026

Scattered showers and thunderstorms are currently ongoing along
a slowly sagging cold front. Thus, a TEMPO group for TSRA and
MVFR conditions has been added to the regional TAF sites between
00z-06z. Beyond that timeframe, a return to VFR conditions is
expected across the board. However, we will need to watch for
patchy dense fog prior to 12z, which could temporarily lower
visibility into the MVFR/IFR range.

...FUNNEL CLOUDS SIGHTED OVER CENTRAL ILLINOIS...

At 145 PM, broadcast media reported a funnel cloud near Bloomington,
and at 235 PM, a storm spotter reported one near the Knox and Henry
county line.

Atmospheric conditions exist that favor the possible formation
of weak circulations along a pre-existing boundary. Some of these
circulations are occurring underneath developing showers and
thunderstorms, where a funnel cloud may develop. Once the rain
begins, the funnel cloud usually dissipates.

Low hanging clouds can also appear to dip up and down at times,
but they will not show signs of any rapid rotation. An actual
funnel cloud will exhibit spinning in a counter-clockwise direction.

In rare instances these funnels may briefly touch down. Stay alert
and be prepared to move to a safe shelter if a funnel cloud
approaches the ground.
