.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 00z TAFs through 00z Tuesday Evening)

Issued at 500 PM CST Mon Dec 29 2025



Satellite imagery showed decreasing cloud coverage as the sun set,

but lingering MVFR cloud streets appear persistent enough to

warrant holding onto MVFR ceilings in the TAF. I'd expect ceilings

to bounce between MVFR/VFR during the first few hours of the

period before improving to VFR by late evening. West-northwest wind

gusts will continue to gradually diminish into tonight. Into

Tuesday, winds turn to southwesterly, around 10 kts, and broken

mid-level (VFR) cloud cover overspreads the area from north to

south. Aside from a few flurries at the start of the period,

precip is not expected this period.
