The episode as NWS TSA wrote it up.
Surface High Pressure built into the region from the north supplying the cold air at the surface. An upper level storm system out of the southwest supplied the lift for the precipitation. Ice accruals of 1/2 to 1 inch were found across the region. The ice also extended across into Adair County Oklahoma. The ice brought down trees and utility lines/poles across the area. The ice track was fairly narrow due to colder air aloft farther north and west that supported frozen precipitation instead of freezing precipitation.
