The episode as NWS OUN wrote it up.
An Arctic airmass became established across Oklahoma and north Texas late on the 21st. As a strong upper level storm system moved into the region, sufficient lift overspread the region to foster widespread light precipitation. Several heavier bands of snow developed over far west-central Oklahoma, leading to significant snow accumulations along I-40. Elsewhere, only light snow accumulations occurred.
