.KEY MESSAGES...
- There is a chance of light snow this evening in southwest
Indiana and portions of southern Illinois. Some accumulating
snow is expected which may lead to slick spots on roads.
Another round of light snow is possible on Saturday.
- Significantly colder air will spread across the region this weekend
with the coldest temperatures Saturday night into Sunday.
Dangerously cold wind chill values (below 0) and impactful air
temperatures are likely.

.DISCUSSION...
Issued at 1253 PM CST Thu Dec 11 2025
A clipper system will slide southeast from the Central Plains into
the Wabash Valley through tonight. A band of light snow will develop
and pivot across portions of southern Illinois and southwest Indiana
from very late this afternoon through the evening. Most guidance
shows the band lifting northeast rather quickly, resulting in only a
few hour period of snow and likely will be largely done by midnight
or shortly thereafter.
No changes to the Winter Weather Advisory (only Pike County).
Buffered it with a Special Weather Statement for counties that could
see a dusting to an inch, resulting in scattered slick spots.
Continues to look like a rather sharp cutoff in snow accumulations
as is common with these clippers.
The next and probably more impactful weather for this forecast
package is the dangerously cold temperatures expected this weekend
as a 1045mb arctic high sinks south across the central CONUS. Air
temperatures likely will drop into the single digits in some areas
Saturday night and the entire region on Sunday night. Winds will be
strongest Saturday night into Sunday morning, resulting in wind
chills ranging from 0 to -10, and possibly as low as -15 in our far
north. We likely will need a Cold Weather Advisory for this period.
High temperatures will only be in the teens to low 20s on Sunday.
Thankfully the cold blast is short-lived, with southwest flow
returning early next week and temperatures back to near normal again
by Tuesday. Above normal temperatures are expected Wed-Thu, with
highs at least into the 50s and potentially even reaching 60 in some
areas by Thursday. Our next chance for precipitation may arrive
Tuesday night into Wednesday associated with warm air advection, but
looks very light if it materializes at all. A frontal passage may
occur later in the week, which could result in greater chances for
measurable rain.

.AVIATION /00Z TAFS THROUGH 00Z SATURDAY/...
Issued at 500 PM CST Thu Dec 11 2025
Expect flight conditions to deteriorate tonight as a clipper
makes its approach and passage. CIGS will degrade thru MVFR at
northern terminals (KMVN/KEVV/KOWB) while southern terminals
(KCGI/KPAH) retain mostly VFR bases. -SHSN are possible north,
where isolated heavier showers may degrade CIGS to IFR and VSBYS
to MVFR prevailing and offer a chance of IFR potential. The
window for snow will be short-lived, but restricted bases will
persist thru the remainder of the forecast north, while
restricted bases SCT south.
