If you thought the worst part of winter was over, you may want to brace yourself as arctic air is about to blast Missouri soon and it may bring big snow with it.
A Cold Weather Advisory has been issued for much of South Dakota. Skies will clear Wed night allowing the temp to drop to near 20 below zero in some areas.
Missouri has had a very nice respite from bitterly cold temperatures and it looks like it will stay that way for awhile. But, an upcoming split of a polar airmass will almost certainly mean that cold is about to return to Missouri with a vengeance.
Illinois is about to enter what will hopefully be the coldest part of winter over the next few days as the National Weather Service is warning of incoming wind chills that could reach 30 below zero.
