Arctic air is plunging southward through the Plains and the leading edge of this cold front will stretch from central Oklahoma to western Illinois by late this afternoon. Low pressure is expected to move eastward along this borderline, pumping warm, moist air over the frigid, surface air, the perfect set up for an ice storm.
Severe icing conditions are forecast for northeastern Oklahoma, much of southern and central Missouri and west-central Illinois. Widespread power outages are expected and travel may grind to a halt. Just another reminder that our mild winter can disappear at the drop of a jet stream!
