.SYNOPSIS...
Issued at 259 AM CDT Sun Oct 24 2021

Multiple severe weather hazards exist today and tonight across
central Illinois, including the potential for flash flooding. Be
sure to review your weather safety plan and stay situationally
aware.

&&

.UPDATE...
Issued at 1038 AM CDT Sun Oct 24 2021

15z/10am surface analysis shows a warm front extending from
Kansas City...to just north of St. Louis...to near Robinson. Winds
have become southerly across the far southern KILX CWA where
temperatures have already risen into the middle 60s. Further
north, chilly E/NE winds north of the front have kept readings in
the 40s and 50s across the remainder of the area. Band of rain
that produced rainfall amounts of 3-5 inches and localized flash
flooding across parts of Morgan County earlier has now lifted
north of I-74. Scattered showers/storms are developing south of
the band and will continue to do so for the balance of the
afternoon. Latest model guidance suggests the warm front will
make it as far north as the I-72 corridor by late
afternoon/evening...so am expecting highs to eventually top the 70
degree mark for all points south of I-72. To the north, highs
from the Peoria area northward will remain in the 50s. As the
atmosphere destabilizes along/near the warm frontal boundary,
storms will increase in areal coverage/strength by mid-
afternoon...with favorable atmospheric profiles for rotating cells
and potentially large hail. The next round of convection will
develop further west along an approaching cold front across
Missouri. These storms will congeal into a linear structure, then
sweep across the southern half of the CWA this evening. Several
CAMs suggest the line will primarily impact points south of
I-72...with damaging wind gusts and perhaps a couple tornadoes.

&&

.SHORT TERM...(Today and tonight)
ISSUED AT 259 AM CDT Sun Oct 24 2021

This period will focus on (1) heavy rainfall and the potential for
flash flooding, and (2) all possible modes of severe weather.

Heavy Rainfall:
A band of moderate to heavy rainfall has already developed north
of a surface warm front. Several ingredients will come together
today to make this an unusual, if not extreme, late October QPF
event. These ingredients include (1) enhanced frontogenetic
forcing north of a sharpening warm front, (2) PWATs that exceed
the 99th percentile of climatology, thanks in part to deep/moist
isentropic ascent, and (3) long temporal exposure to these
conditions with the surface low steadily lifting across our
region.

The latest observed QPEs from dual-pol and MRMS are already
offering pockets of 1"+/hr rates within this rainfall band
spanning west central Illinois, and this air mass will continue to
moisten throughout the morning as the warm sector lifts closer to
our area.

We generally like what the latest HREF is offering in terms of
QPF across central Illinois. We particularly like the 24-hr QPF
leveraging the LPMM, which suggests a swath of 1-3" between I-72
and I-80, with localized amounts of 5-7" possible. Despite the dry
antecedent conditions, we believe there is enough variables in
play to support flash flooding and river flooding. For this
reason, we have collaborated a Flash Flood Watch, valid until 12z
Monday morning.

Severe Potential:
There will be a lengthy window of time for severe weather to
develop today, as both a warm front and cold front push across the
region. We believe this timing to span 4pm to Midnight, with all
modes of severe weather possible.

Obviously, there will be plenty of convective debris around to
dampen instability throughout this event, with most short term
guidance maintaining a cap throughout the warm sector. However, a
few parcels may become surface-based by 20-21z as lapse rates
steepen ahead of an intruding 500-mb wave, and low 60s surface
dewpoints pool along the warm front, which will likely have lifted
along the I-72 corridor by then.

If parcels can become surface based near the vicinity of the warm
front, there will be 500-1000 J/kg of available SBCAPE juxtaposed
to 50 kts of deep layer shear, and SRH values ranging between
300-400 m2/s2, per the RAP. This favors supercell development.

Given the modest instability and significant kinematic field in
place, we believe there is a brief window later this afternoon or
early evening where isolated supercells may be capable of
producing a strong tornado or two. This is especially evident
from the 00z HREF, where good clustering of updraft helicity
swaths lie along the I-72 corridor, and the STP has trended
upward. Mesoanalysis will be crucial this afternoon, with the
position of the warm front and system triple point still somewhat
uncertain.

By late evening, storms are likely to congeal into a QLCS as the
surface cold front enters in from the west. As the front becomes
more N-S oriented, the 0-3km shear vectors appear to become line
normal, with magnitudes between 30-40 kts over a large area. If
sufficient 0-3km CAPE exists along the cold front, there will
likely be a substantial straight-line wind threat, with the
potential for a few embedded mesovorts, especially where bowing
segments develop.

Convective activity then looks to exit our CWA shortly after 06z.

.LONG TERM...(Monday through Saturday)
ISSUED AT 259 AM CDT Sun Oct 24 2021

Gusty winds and scattered showers will linger into Monday as the
dynamic storm system makes its departure. Large scale subsidence
will begin to work in behind the departing wave, as an amplified
ridge of high pressure quickly builds across the region on
Tuesday.

Another dynamic storm system looks to lift across the Lower
Mississippi Valley Wednesday into Thursday, with the upper-level
wave becoming cut-off over the Tennessee Valley by Friday. This
spells a period of wet and unsettled weather through the middle
and late stages of this week with temperatures near or slightly
below normal.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 111 PM CDT Sun Oct 24 2021

IFR ceilings will prevail across central Illinois for the next
couple of hours before a warm front pushes northward and improves
ceilings later this afternoon/evening. Based on current placement
of front and 12z NAM/HRRR data, it appears will rise to VFR at
KSPI by 20z...then further NE to KDEC/KCMI by around 22z. KPIA
will likely remain IFR/MVFR for the entire 18z TAF period. Radar
imagery shows a relative lull in precip: however, a line of
convection is beginning to take shape across western Missouri.
These storms will continue to develop and track E/NE into central
Illinois late this afternoon and evening. Will continue to feature
VCTS at the terminals for now, but will likely upgrade to
prevailing once radar trends are more apparent and exact timing
becomes certain. One or two lines of storms will push through the
area this evening before a cold front sweeps the convection into
Indiana after midnight. Once the front passes, winds will veer to
NW and MVFR ceilings will spill back across all of central
Illinois overnight into Monday morning. Winds will also become
strong/gusty behind the front, with numeric guidance and forecast
soundings suggesting gusts in excess of 30kt on Monday.
