.DISCUSSION...

Issued at 142 AM CST Tue Dec 30 2025



Compared to the previous days, this forecast would be considered 

"boring". The winds have relaxed and we are moving into a period of 

drier, but seasonably cool weather. There is a cold front that will 

move through tomorrow that could have some snow flurries nick the

northern edge of the forecast area in the afternoon, but the 

amounts are not impressive. There is a 25-50% chance of more than 

a tenth of an inch, north of I-74, with this wave. This cold front

could also deliver some single digit wind chills north of I-70, 

Thursday morning. After tomorrow, we kick off the new year with a 

period of dry weather for much of the first week of 2026. 



This morning is pretty chilly with wind chills near zero (+- a 

couple degrees), but it is only temporary. Starting today, highs 

will be in the upper 20s to upper 30s. There is some gradual warming 

into the weekend. Highs by Sunday/Monday next week looks to be in 

the 40s. A cold front appears to move through early next week to 

drop highs back into the 30s. Lows of teens to upper 20s are 

forecast through the end of the seven day period.

.AVIATION...  (For the 18z TAFs through 18z Wednesday Afternoon)

Issued at 1141 AM CST Tue Dec 30 2025



Ahead of a weak frontal boundary, mostly light snow showers are

drifting southeast across eastern Iowa and northwest Illinois.

These may graze PIA and BMI to briefly reduce visibilities this

afternoon and evening, though the probability of a flight category

drop seemed too low (10-20%) to add that to the TAFs at this time.

Early Wednesday morning, the front will cross the area, bringing 

a wind shift to northwesterly and a medium-high (60-80%) chance 

of MVFR ceilings by 12z.
