.DISCUSSION...
Issued at 136 PM CDT Thu Apr 10 2025

Latest water vapor imagery showed a series of shortwaves just to
our west and northwest that will track southeast across our area
through this evening. At the surface, a weak/stationary
convergence boundary was analyzed along a Galesburg-Springfield-
Flora line at 18z. Forcing ahead of these waves, and along and
south of the boundary will be a focus for scattered convection
until around 03z. Thermodynamic fields support a few strong
storms, primarily due to steep mid level lapse rates and a
pronounced near surface dry layer (inverted-v soundings below 850
mb). This would promote a few stronger downdrafts and small hail,
possibly up to quarter size. Deep layer shear is unimpressive,
generally under 25 kt, so we don't expect much organization to
these storms and mainly a pulse strong/severe storm.

Next item of interest is a chunk of seasonably cool air sliding
into the Midwest behind this system. 850 mb temps drop to -3C
early Saturday morning, concurrent with surface ridging sliding
over our eastern CWA. Near ideal radiational cooling in place,
especially near and east of I-57 where blended guidance shows lows
30-32F. Cooler end of guidance has upper 20s lows, so sensitive
early season vegetation could again be at risk, and will be
monitoring this period for a potential Freeze Warning.

A surge of warm advection will overspread the region this weekend
as return flow sets up on the back side of the ridge, with gusty
south winds pushing highs into the lower on Sunday west of I-55.
A few showers could occur as the low level jet veers into the area
Sunday morning, but this looks brief and focused farther to the
north.

Global ensembles continue to advertise a closed 500 mb low
crossing the far upper Midwest late this weekend, and a sub 1000
mb surface low tracking through the northern Great Lakes Monday.
This will keep windy conditions going Monday, along with our next
chance of showers and storms. 12z guidance shows a progressive
frontal passage, clearing central IL by mid morning. If these
trends hold any strong/severe storms would be more likely to our
east, in line with SPC's Day 5 outlook. Beyond this system,
cooler and dry air looks to overspread the area into midweek.

.AVIATION...  (For the 18z TAFs through 18z Friday Afternoon)
Issued at 1210 PM CDT Thu Apr 10 2025

Scattered showers/storms are forecast to develop later this
afternoon along a weak convergence boundary, particularly from
KSPI/KDEC to the south. Included a PROB30 to account for this,
with terminals farther north staying dry. This activity will
diminish by mid evening as a backdoor cold front works in from the
northeast. This will turn winds solidly northeast across the
entire area at 10-15 kt. After 06z, lake enhanced moisture on the
northeast flow should bring a layer of MVFR clouds in from the
northeast, with the back edge of this cloud deck eventually
pushing south of the area through late morning.
