Severe thunderstorms affected portions of north central Kansas during the evening hours of May 26th. Initial thunderstorm development for this event occurred well west of the area across NW Kansas and SW Nebraska during the late afternoon hours, in which several supercells developed in the vicinity of a low pressure, warm front, and dry line triple point. This is where the most severe weather, including tornadoes, occurred. Additional intense supercells developed along Interstate 70 near Russell, Kansas, but this activity remained primarily south of the Hastings CWA. However, a small area of severe wind gusts occurred further north into Mitchell County on the edge of stratiform rain and caused some power pole and tree damage in and around the Beloit area. The initial western supercells weakened before moving into our area. However, additional surface based supercells developed west of Hill City between 8-9PM CDT, and moved into western portions of Phillips and Rooks Counties between 9-10PM CDT. Large hail up to golf ball size was reported with a supercell in Rooks County. This supercell transitioned to a bowing structure as it shifted eastward and later produced quarter size hail in Mitchell County as well as damaging wind gusts in Jewell County between 10PM and midnight. Gusts were estimated to be at least 75 MPH as at least 8 power poles were snapped along with trees 18-24 inches in diameter. Non-severe thunderstorms continued into the early morning hours of May 27th.
Overall, this event was less impactful than forecast. Nearly all of the Kansas portion of the Hastings CWA was in a ���Moderate Risk��� in the SPC Day 1 Convective Outlook. A potent upper level disturbance provided strong deep layer shear, but the early-day convection along Interstate 70 led to decreased surface based instability further north. Also, the upper disturbance was slower to eject onto the Plains that originally expected. Ultimately, this kept the most intense convection (and associated tornadoes and significant severe hail) west and south of north central Kansas.
