Additional snow showers are expected Sunday. Snow will be off and on once again, but mainly focused on sections of northeast Missouri and west-central Illinois. Drivers should remain cautious, as visibility will change rapidly in and out of snow showers. Practice extra caution, especially as you approach bridges and overpasses. A few slick spots are possible.
An arctic airmass will bring cold conditions to the area over the next few days, with morning wind chills below 0 in many areas each day through Tuesday.
