Temperatures fall once again Thursday with a quick shot of snow over northeast Missouri, tracking southeast through interior sections of Illinois. Most of our accumulation will be light. However, be aware if traveling northeast toward Springfield, IL, where higher totals will impact travel Thursday afternoon into Thursday night.
It's going to be cold the next few days, but it'll be even colder this weekend. Wind chill values could at times reach dangerous levels.
