Between 7-10 p.m. CDT on this Friday evening, a compact mesoscale convective system (MCS) with an initially intense, embedded supercell rolled from west-to-east across primarily Rooks, Osborne and Mitchell counties in this North Central Kansas area, producing several reports of damaging winds/large hail (including up to tennis ball size). This severe storm cluster first organized in northeast Colorado during the early-mid afternoon before traversing northwest Kansas mid-late afternoon and eventually infiltrating mainly the northern half of Rooks County between 7-8 p.m. CDT, during which time the dominant supercell reached its peak intensity within the local area. In Rooks County, there were several reports of hail ranging from ping pong ball up to tennis ball size, and broken windows were reported at a business south of Stockton along Highway 183. Also in Rooks County, damaging winds estimated up to 70 MPH caused tree damage in Damar and overturned a camper at Webster State Park. Between 8-9 p.m. CDT, the dominant supercell weakened slightly over Osborne County as it merged with other convection drifting north out of central Kansas, but it still yielded a report of ping pong ball size hail eight miles south-southeast of Osborne. Finally, between 9-10 p.m. CDT the most intense convection transitioned to a more linear mode as it crossed Mitchell County, yielding an unofficial mesonet-measured wind gust of 59 MPH seven miles east of Tipton. Although the main storm cluster departed east of the local area by 10 p.m. CDT, trailing showers/weaker storms lingered for at least a few hours before convection departed North Central Kansas for the night. Rainfall-wise, although limited parts of the area received at least 1-2 inches in a short time, there were no reports of significant flooding.
Turning to the meteorological background, this was a fairly classic setup for early-summer MCS development. In the mid-upper levels, the primary driver was a shortwave trough slowly migrating from the CO/WY/NE border area into the Central Plains over the course of the afternoon-evening. At the surface, North Central Kansas resided slightly north of a generally west-east oriented quasi-stationary front stretched from southern into east central Kansas. Locally, the early evening pre-convective environment was defined by temperatures in the 80s and dewpoints in the 60s (F), with mesoscale parameters featuring moderate mixed-layer CAPE of 1000-2000 J/kg but fairly strong deep-layer wind shear of 40-45 knots.
