Although it did not cause significant travel issues, and it only stuck around briefly before rapidly melting, much of this six-county north central Kansas area accumulated one of the heaviest snows on record to occur this late in the spring. Specifically, the majority of the area measured somewhere between 1.5 and 5.5 inches of wet, slushy snow between the late evening of Monday the 19th and sunrise on Tuesday the 20th. Per CoCoRaHS/NWS observer measurements and NOHRSC analysis, the highest totals of 4-6 targeted the southern-most local counties (Rooks/Osborne/Mitchell), including 6 near Hunter, 5.5 in Natoma and Covert, 5 ten miles south-southwest of Beloit, and 4.5 four miles west-northwest of Plainville. Within the northern three counties (Phillips/Smith/Jewell) a few of the higher tallies included 3 at Ionia and 2.6 in Lebanon. A sampling of NWS cooperative observer stations for which this was the heaviest snow on record to occur on/after April 20th included: Natoma, Smith Center, Plainville 4WNW, Cawker City and Covert.
As mentioned, this snow did not stick around long, as while it accumulated during overnight temperatures in the upper 20s-low 30s (F), it melted quickly under widespread sunshine on the 20th as afternoon readings climbed well into the 40s. In the mid-upper levels, this event was driven by the gradual north-to-south passage of a fairly narrow, but intense zone of mid-level frontogenesis (very evident at 700 millibars). In the bigger picture aloft, this frontogenetic zone intensified along the southern edges of an expansive trough dropping south-southeast through the central United States. At the surface, winds across North Central Kansas during this event were  not a major issue, averaging only 5-15 MPH from the north. These relatively light breezes were fostered by expansive high pressure (1030 millibars over the Northern Rockies) oozing southeastward through much of the central and northwestern United States, in the wake of a strong cold front that surged southward across North Central Kansas about 24 hours prior to this event.
