Starting during the late evening hours of Saturday the 22nd, peaking in intensity overnight and gradually moving out by late morning on the 23rd, a notably-narrow band of heavy snow in the 6-8 inch range targeted mainly the northern halves of Phillips and Smith counties, with isolated 6 amounts also reported as far east as central Jewell County. Meanwhile, southern portions of these counties, along with all of Rooks, Osborne and Mitchell counties observed little to no accumulation. Within this six-county portion of North Central Kansas, the primary heavy snow band generally extended no more than 5-10 miles either side of a line stretched from near Long Island to Mankato. Per NWS cooperative observers, a few of the highest official snow totals featured 8.9 at Lebanon, 8.0 at Smith Center and 6.5 at Mankato. Only a short distance south of the primary band, locations such as Logan and Beloit hardly saw a single snowflake. Fortunately, winds were not a major issue during this event, with sustained northeasterly speeds of generally 10-15 MPH keeping blowing and drifting to a minimum.
Timing-wise, this quasi-stationary heavy snow band first started building southward into extreme North Central Kansas out of southern Nebraska during the 10 PM-12 AM time frame, peaked in intensity during the pre-dawn hours, and gradually weakened and slid off to the east during the morning of the 23rd. Not surprisingly, the meteorological culprit for this narrow, banded snow event was a concentrated zone of mid level frontogenesis evident at the 700 millibar level, driven by lift from passing upper level jet streaks. On the larger scale aloft, a broad, low-amplitude trough encompassed most of the nation. At the surface during this snow event, North Central Kansas became increasingly under the influence of high pressure building southward out of southern Canada.
