.DISCUSSION...

Issued at 225 AM CST Wed Dec 31 2025



Welcome to the final day of 2025! There is a cold front that will 

move through today that could have some snow flurries move north of 

I-70 this afternoon, but the amounts are not impressive if you see 

any flakes at all. There is a 20-40% chance of more than a tenth of 

an inch, north of I-74, with this wave. Higher probs are found as 

you move northeast outside of the forecast area. This cold front 

could also deliver some single digit wind chills north of I-72, 

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

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



Highs will be in the upper 30s to low 40s today. Highs tomorrow will 

top out in the upper 20s to mid 30s as a result of the cold front 

passage today. There is some gradual warming into the weekend after 

tomorrow as high pressure builds over the Midwest. Highs by 

Sunday/Monday next week get in the 40s. Lows of teens to upper 20s 

are forecast through Sunday. Looking at the CPC 6-10 day outlook, 

the trend toward above-normal temperatures is favored to persist 

through the first week of January.

.AVIATION...  (For the 06z TAFs through 06z Wednesday Night)

Issued at 1052 PM CST Tue Dec 30 2025



A few shortwave disturbances embedded in northwest flow aloft 

will bring potential for MVFR or even brief/isolated IFR 

cigs/vsbys over the upcoming 24 hours. The first may continue to

bring some patchy flurries and freezing drizzle as well as MVFR

cigs near KCMI as it exits the area around 06Z. Another looks to 

arrive overnight, and will likely bring lowered cigs to MVFR range

near the I-74 corridor after 08Z. The last looks to have the most

potential for impactful conditions, with MVFR cigs and vsbys 

after 16Z-18Z as well as a chance for light snow. Winds SW 

08-12kts shifting to WNW by 08Z-10Z and increasing to 10-15 kts

with gusts around 20 kts. Winds decreasing to around 10 kts by

around 00Z.
