Several inches of light to moderate snow fell across part of the area on this Friday and Saturday. During the daylight hours Friday, a large shield of rain and snow formed across southern Kansas, and it gradually lifted into northern Kansas. Around midday, light rain and snow began falling across Rooks, Osborne, and Mitchell counties. Any rain that was falling changed to snow and, by late afternoon, the precipitation shield had lifted further north, with snow falling across Phillips, Smith, and Jewell counties as well. By 6 PM CST, a single, long, fairly narrow deformation snow band had evolved and extended from near Garden City across north central Kansas to Nebraska City, Nebraska. This band remained nearly stationary until 1 AM CST Saturday. The band then began slowly drifting east while gradually diminishing in intensity. The snow ended from west to east, across north central Kansas, between 6 AM and 2 PM CST Saturday. All six counties were covered by a minimum of 4 to 6 inches of fresh snow. The highest amounts included 9.0 at Hunter, 8.5 inches at Plainville, 8.0 at Beloit and Randall, 6.5 at Natoma, and 6.0 at Osborne, Jewell, and Smith Center. Surface winds were fairly light with this event, averaging 5 to 10 MPH Friday afternoon and night. During the daytime Saturday, winds increased to 10 to 20 MPH, which is tame for most snowstorms here. So, problems with drifting were minimal. Because this occurred primarily on a weekend, the impacts were pretty low.
This snowstorm occurred in the absence of any surface features. The closest surface system was a weak 1009 mb low moving east through Oklahoma. The upper-levels exhibited an omega shaped pattern with a high-amplitude ridge extending from Arizona to Idaho. A downstream trough was along the Colorado-Kansas border Friday evening, and this trough closed off into a 500 mb low along the Oklahoma-Kansas border by dawn Saturday. 300 mb analyses indicated strong divergence over the area while the band was strongest, with a coupled jet streak configuration. This band developed within  the area of deformation, in the 700-500 mb trough. Despite the appearance on radar, though, mesoanalyses did not indicate frontogenesis was occurring.
