The episode as NWS OUN wrote it up.
A clipper-type storm system moved through the central Plains during the overnight hours of the 9th and into the 10th. Although much of the heavier winter weather occurred north of the Oklahoma/Kansas border, light snow developed as far south as northern Oklahoma. The snow developed ahead of an arctic front that dropped temperatures into the teens. Some blowing and drifting of the snow occurred behind the front, with a few wind gusts over 30 mph. Snowfall totals ranged from 1 to 3 inches.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Norman, OK wrote its last area forecast discussion before the first event at Jan 9, 1:53 PM CST, 1 hour 7 minutes earlier.
