- Freezing rain potential tonight/Friday

Low pressure passing by to the south across Indiana will result in
a north to northeast wind today through Friday morning. Cooler air
will begin to filter into the cwa tonight from southeast Ontario
sending surface temperatures below freezing. Meanwhile, aloft, an
approaching low in Iowa and it`s LLJ will pull warmer air
northward over the cwa resulting in a classic freezing rain
sounding. Overall, the forecast hasn`t changed much during the
past few days. QPF has decreased a bit with the latest guidance
since yesterday, but we`re still expecting around a tenth of an
inch of ice beginning just prior to sunrise and continuing into
the afternoon, before the wave moves east and takes the
precipitation with it. Surface temperatures will remain aob
freezing in the far northeast cwa and those areas will see the
most ice; the far southwest cwa might not see much ice at all.

After collaboration with surrounding offices, we`ll wait to issue
any headlines, since the event likely won`t begin until closer to
sunrise Friday.

Icy roads/sidewalks/driveways are a distinct possibility Friday
morning until they can be treated.

- Rain Sunday changing to snow Monday, colder

An upper ridge will move over the Great Lakes Saturday and Sunday
sending high temperatures into the 40s and 50s Sunday. Meanwhile,
low pressure over the Plains will move east resulting in rain
Sunday that`ll change to snow Sunday night as colder air flows
into the region behind the trailing cold front. Some lake effect
snow will develop as h8 temperatures fall to -16c Monday. Snow
showers will linger into Tuesday before the cold air lifts out.

Another brief shot of snow is possible Wednesday night as a
clipper moves southeast across northern Lower, but details remain
elusive as this wave of low pressure remains far enough north
that it may not impact the cwa.

.AVIATION /12Z TAFS THROUGH 12Z FRIDAY/...
Issued at 629 AM EST Thu Dec 25 2025

Latest IR loop shows high clouds moving over the state. There is
also a band of stratocu over northern Lower that`s moving south
and will move over the terminals later this morning and then move
out by late afternoon. We`ll then see a period of VFR until late
in the period when we expect light freezing rain to develop after
09z along with MVFR cigs.
