A public report was shared from the WQAD Twitter page.
Between 10:30 a.m. and 12:30 p.m. CDT on this Thursday, an isolated, elevated supercell storm dropped east-southeast out of Nebraska and across primarily northern and eastern Phillips County along with parts of Smith County, before rapidly weakening. Along the way, there were a handful of severe-criteria hail reports, including stones up to golf ball size near Agra and quarter size in Kensington. As the storm began to weaken, penny size hail fell southeast of Smith Center. In the wake of this supercell, a few additional strong storms brushed across far northern Smith and Jewell counties during the early afternoon, but all of this six-county North Central Kansas area was pretty much storm-free by 3 p.m. CDT.
The development of this isolated severe storm was fairly unexpected, given rather weak forcing aloft and also warm mid level temperatures. However, in the mid-upper levels, the broad quasi-zonal flow in place over northern Kansas did in fact feature a subtle disturbance moving in from the west, along the southern periphery of a better-defined, low amplitude shortwave trough tracking out of the Northern Rockies into the Dakotas. Despite temperatures at the 700-millibar level averaging at least 12-14 C, this rogue severe storm thrived in a mesoscale environment featuring most-unstable CAPE around 2000 J/kg and seasonably strong deep-layer wind shear of 40-50 knots.
