Primarily between 7 pm-1 am CDT on this Saturday evening, much of this six-county North Central Kansas area observed widespread thunderstorm activity. However, all severe-criteria hail and wind reports, along with the heaviest pockets of torrential rainfall, targeted Jewell County along with northern and eastern portions of Smith and Mitchell counties. All severe reports in these areas occurred between 8-10 pm CDT in association with a southeastward-drifting supercell cluster that first blossomed over Franklin County Nebraska before crossing the state line into the local area. As this initially rather discrete severe storm affected Smith County mainly between 8-9 pm CDT, it resulted in several reports of quarter to golf ball size hail in the Bellaire and Lebanon areas, and even one baseball size report just south of Lebanon. In that same portion of Smith County, estimated wind gusts up to around 80 MPH downed several power poles. Even slightly outside the main path of this storm, severe outflow winds of 59 MPH were measured at Smith Center airport. As the initial supercell merged into newly-developing convection over Jewell and northern Mitchell counties to become a larger-scale cluster, additional severe reports included estimated 60 MPH winds at Burr Oak and half dollar size hail several miles east of Beloit. At the same time severe weather was ongoing in Jewell and Mitchell counties, additional strong storms flared up farther west across parts of Phillips, Rooks, Smith and Osborne counties between 9-10 pm CDT. After 11 pm CDT storms across the local area weakened considerably, and by 2 am CDT the entire area was essentially rain-free.
Rainfall-wise, the primary severe storm cluster produced three distinct, albeit small bullseyes of very heavy rainfall of generally 3-5. One of these was in northeastern Smith County, another in south central Jewell County where the NWS cooperative observer at Ionia measured 4.36, and the third one in northeastern Mitchell County where a CoCoRaHS observer reported 5.00 approximately five miles east of Beloit. Despite these pockets of very heavy rain there were very few ground-truth reports of flooding, although the Solomon River near Simpson crested only a few inches below flood stage on Sunday the 10th.
This was a fairly typical late-summer severe weather event featuring fairly high instability values but only modest deep layer wind shear and weak large scale forcing. In the mid to upper levels, generally quasi-zonal flow was in place over the Central Plains, containing one or more fairly subtle shortwave troughs. At the surface, storms initiated in the vicinity of a northwest-southeast oriented quasi stationary front draped through the local area along an axis from western Nebraska to southeast Kansas, with this front partially comprised of a remnant outflow boundary from storms the night before. With surface dewpoints well into the 60s F across the local area, most-unstable CAPE climbed as high as 2000-3000 J/kg. Although at least one storm in the local area briefly exhibited supercell structure, 0-6 kilometer deep layer wind shear only averaging around 30 knots promoted a predominant multicell/quasi-linear mode.
