KEY MESSAGES

- A quick moving band of snow showers is possible (15-20% chance) across the Quad State today. A quick dusting to a half inch is possible; however, widespread road impacts are not anticipated. - A surge of cold air will continue to push into the region today, with a second even colder surge Sunday night into Monday. There is a greater than 90% chance of wind chill values remaining below freezing throughout the Quad State through Wednesday morning.

- The northern half of the area has a greater than 90% chance of winds chills remaining below 20 degree from late Sunday night through early Tuesday morning.

- A wintry mix will be possible toward the end of the week (Wednesday night into Thursday) for mainly southern Illinois into southwest Indiana. Exact timing of the frontal boundary/features will determine if and where travel impacts may occur, but worth keeping an eye on that time period for now.

DISCUSSION

Issued at 148 AM CST Sat Jan 17 2026

Winter time is moving back in full force through much of this forecast! A strong cold front moving in from the northwest will allow temperatures to be much colder today with most locations staying below freezing for high temperatures. Additionally, the cold front is expected to become nearly stationary throughout the day before pushing off to the southeast this evening; however, the will be enough forcing along the boundary to touch off a band of snow showers. In fact, these snow showers are associated with the same system that brought snow squalls to northwest and central Missouri Friday evening/night. The snow squall parameter does decrease as the FGEN forcing diminishes, but it is still possible that the band could produce a quick burst of snow as it moves through the area from west to east throughout the day. Still not anticipating much in the way of snowfall totals (about a 15% chance of seeing greater than 0.2 inches), but enough to briefly reduce visibility and result in a dusting.

Broad troughing will then linger across the eastern CONUS with multiple shortwaves rounding the base of the trough and re-enforcing the colder air through at least Tuesday. The next shortwave will be Sunday afternoon/evening, which will be the next chance for a few snow showers or flurries. Not a lot of moisture to work with for that time period, so not expecting any impacts. The next will be roughly Monday night into Tuesday morning with even lest moisture, so just left that period dry for now. Outside of those small chances for flurries or very light snow showers, the main issue will be the cold air in place. High temperatures will struggle to get above freezing on Sunday and will remain well below freezing (in the 20s) for Monday before moderating a bit on Tuesday. Lows will be quite cold, dropping into the teens Sunday night and low teens and possibly some single digits Monday night into Tuesday morning. Wind chill readings will drop into the low single digits above zero through Tuesday morning!! In fact there is about a 60-80% chance of seeing single digit wind chill values each night and morning through Tuesday morning.

Temperatures will warm toward the end of the week, but only into the mid to upper 30s for most of the area. High pressure is expected to be in place across the southeast US, allowing moisture to advect northward into the Quad State area for Wednesday night into Thursday. At the same time, the next cold front is expected to sag southeastward into the area. There may be a brief overlap of colder air and deeper moisture to allow for a wintry mix of rain, freezing rain and snow. The exact details with this system will need to be ironed out over the next several days, but it is worth keeping an eye on if you have travel plans for the end of next week.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 502 AM CST Sat Jan 17 2026

Mid clouds will pass through the TAF sites today with a few snow showers possible this morning over southern IL/southeast MO and this afternoon elsewhere. Minimal impacts are expected from any snow showers or flurries, but a very brief visibility reduction is possible. The probability of a snow shower impacting any of the TAF sites is low enough to leave out of this issuance. Otherwise, gusty winds will be the rule through most of the day before diminishing tonight under clearing sky.
