For this six-county North Central Kansas area, the first snow event of the 2016-17 winter season unfolded on this Saturday. While accumulations of generally 1-2 inches were noted in parts of Rooks, Phillips and Smith counties, the highest totals closer to 3 concentrated within Osborne and Jewell counties. Thanks to the wet, slushy nature of the snow, marginal near-freezing temperatures and light winds averaging around 10 MPH or less, this was a fairly low-impact event travel-wise. According to a combination of CoCoRaHS and NWS cooperative observers, some of the highest totals featured: 3-4 in and near Natoma, 3.5 near Alton, 3.0 in Mankato and Ionia, and 2.6 in Burr Oak.
As for precipitation timing, this was pretty much an all-day event. A shield of light-to-occasionally-moderate snow or a rain/snow mix moved in from the southwest by around 8 AM and finally departed Osborne and Jewell counties to the east between 10 PM-midnight. Thanks to daytime high temperatures topping out 32-34 degrees, some snow melted as it fell, with the most efficient accumulations holding off until late in the day/evening. As for forcing in the mid-upper levels, things were largely driven by a broad zone of isentropic lift focused out ahead of a slow-moving shortwave trough translating through the Central Plains from northwest-to-southeast. At the surface, high pressure was centered over the IL/IN area, with a weak ridge axis extending back westward into northern Kansas, keeping winds light.
